When using theT41 green cutting disc size, the hardness of the grinding wheel is also a problem that users often pay attention to. Because its hardness affects the effect of the cutting material, how to choose the hardness of the T41 green cutting disc grinding wheel? The hardness of the grinding wheel of the cutting disc refers to the difficulty of the abrasive disc falling off under the action of external force. In order to meet the requirements of different workpiece material grinding, the grinding wheel is divided into different hardness grades. The grinding wheel is selected too hard, the blunt abrasive grains are not easy to fall off, the grinding wheel is easy to block, the grinding heat is increased, the workpiece is easy to burn, the grinding efficiency is low, and the surface quality of the workpiece is affected; the grinding wheel is selected too soft, and the abrasive grain is also off when it is sharp. Increases the wear of the grinding wheel, easily loses the correct geometry and affects the accuracy of the workpiece. Therefore, the choice of the hardness of the grinding wheel should be appropriate, and should be considered according to the contact area of the grinding wheel and the workpiece, the shape of the workpiece, the way of grinding, the cooling method, the type of bonding agent of the grinding wheel and other factors.

In the processing of grinding machines, cutting machine tools or portable power tools, the wheel guards are one of the important means to protect the personal safety of the operators. Moreover, the wheel guards not only protect the personal safety of the operators, but also improve them through improvement. An important entry point for processing efficiency.
Protection problem The protective cover is the most important protection device of the grinder. Its function is: When the grinding wheel is damaged due to work, it can effectively cover the grinding wheel fragments and ensure the safety of personnel.
The shape of the wheel guard is round and square, and the maximum opening angle is not allowed to exceed 90°; the material of the shield is steel with a tensile strength of not less than 415 N/mm2. When replacing a new grinding wheel, the protective cover should be installed firmly and reliably, and the protective cover should not be dismantled or discarded.
The existing protective cover is usually composed of a simple cover, and an opening for the cut off disc for stainless steel machine is opened on the upper side, and the debris is prevented from flying out from the periphery during the processing. However, since the residue remains in the protective cover after being blocked by the protective cover, it takes a long time, and a lot of residue and dust are accumulated in the protective cover. In order not to hinder the cutting work, the construction personnel also need to regularly clean the residue. Cutting operations cause a lot of inconvenience and affect work efficiency. In addition, too much residue in the shield can easily spill to the outside, affecting the surrounding environment, and too much residue can easily cause secondary splashes during the cutting process and damage the construction personnel.cut off disc for stainless steel

Resin bond cutting sheets and diamond cutting sheets are all kinds of cutting sheets. What is the difference between the two? Resin cutting piece is a cutting piece made of resin, such as phenolic, epoxy, polyurethane, etc., polyvinyl alcohol, resin cutting piece is high in strength, can add reinforcing fiber mesh and steel bar in aluminum abrasive cutting disc, such as cutting piece, grinding At present, most of the resin cutting sheets are not waterproof and can not be ground with grinding fluid. Of course, there are some resin cutting sheets that need to be added with grinding liquid grinding, such as epoxy. The grinding of resin cutting sheets is smooth and not easy. burn. The resin cut sheets are generally classified into ordinary resin cut sheets and super hard resin cut sheets according to abrasives. The ordinary resin cutting sheet is a cutting piece mainly composed of white abrasive, brown fused alumina, silicon carbide and the like, and the super-hard resin cutting sheet is a 5 inch resin cutting disc for metal mainly composed of diamond or CBN. Resin cutting discs for grinding high speed steel, tool and die steel and superalloys above FtRC50, super heat resistant stainless steel, cermets, ceramics, glassware, limonite, high speed steel, alloy tools and many others The ideal grinding tool for superhard materials. Diamond cutting piece, which is made of diamond abrasive as raw material, and is made of metal powder, resin powder, ceramic and electroplated metal as bonding agent, and is made of round-shaped fixed abrasive with central through hole. It is also grinding cemented carbide and glass. Special tools for high-hard and brittle materials such as ceramics and precious stones. The resin cutting piece is a cutting piece made of resin, which is widely used in the industries of cutting piece, double end face, heavy load cutting piece, polishing wheel, etc. The selection of the 14 inches cutting disc is seriously affecting the grinding effect and the grinding cost. Key factor. At the same time, different resin-cut sheets have different applications depending on the shape and size, and the abrasives and binders are different. There are different types of refiners for resin-cut sheets, among which white fused alumina, black silicon carbide, and brown fused alumina are widely used. 1 White corundum (WA): The hardness is slightly higher than that of brown corundum. The toughness is lower than that of brown corundum. When grinding, the abrasive grains are easily broken, so the grinding produces small heat, which is mainly suitable for grinding hardened steel, stainless steel and high carbon. Metal materials such as steel and high speed steel. 2. Black silicon carbide (C): It is brittle and sharp, and its hardness is higher than that of white corundum. It is mainly suitable for grinding metal materials with low mechanical strength, such as cast iron, yellow copper and aluminum. 3 Brown corundum (A): high hardness and high toughness, mainly suitable for grinding metals with high tensile strength, such as cast iron, carbon steel, alloy steel, hard bronze and other metal materials.

Electroplated metal diamond cutting piece Advantages of electroplated diamond cutting blades: 1 The electroplating process is simple, the investment is small, and the manufacturing is convenient; 2 no need to trim, easy to use; 3 single-layer structure determines that it can reach a very high working speed, currently abroad has reached 250 ~ 300m / s; 4 Although there is only a single layer of diamond, there is still enough life; 5 For the rollers and cutting blades with high precision requirements, electroplating is the only manufacturing method. Because of these advantages, electroplated dicing sheets occupy an undisputed dominant position in high-speed, ultra-high-speed grinding. Defects in electroplated customized metal cutting disc: There is no strong chemical-metallurgical bond on the bonding surface between the plating metal and the substrate and the abrasive. The abrasive is actually embedded in the coating metal by mechanical embedding, so the holding power is small, and the diamond particles are In the high-efficiency grinding with heavy load, it is easy to fall off (or the coating is peeled off), resulting in overall failure; in order to increase the holding force, the thickness of the coating must be increased. As a result, the bareness of the abrasive grains and the space of the chip are reduced, and the cutting piece is prone to occur. Blockage, poor heat dissipation, and the surface of the workpiece is prone to burns. At present, the domestic electroplated cutting piece manufacturing has not yet realized the optimal topography of the cutting piece according to the processing conditions. The inherent disadvantages of the single-layer electroplated diamond cutting piece will inevitably limit its application in efficient grinding. Single layer brazed diamond cutting piece In order to give full play to the role of diamond, it is necessary to increase the holding force of the bonding agent on the diamond and improve the bonding strength of the cutting piece. The single-layer high-temperature brazing super-hard abrasive cutting sheet can overcome the shortcomings of the 125*1*22 EN12413 cutting disc, and can realize the chemical metallurgical bonding between the diamond, the bonding agent and the metal matrix, and has high bonding strength, and only needs to maintain the bonding layer thickness. In the high-load high-speed and high-efficiency grinding, the abrasive grains can be firmly held in the high-load high-speed and high-efficiency grinding, so that the exposed height of the abrasive grains of the brazed cutting piece can reach 70% to 80%, thus increasing the capacity. The chip space, the cutting piece is not easy to block, and the use of the abrasive is more sufficient. Under the same processing conditions as the electroplated cutting piece, the single-layer high-temperature brazing super-hard abrasive cutting piece has lower grinding force, power loss and lower grinding temperature, which means higher working speed can be achieved, which is 300-500m. Ultra-high speed grinding above /s has special significance.

An angle grinder, also known as a grinder or a disc grinder, is an abrasive tool used for FRP cutting and grinding. An angle grinder is a hand-held power tool that uses FRP to cut and polish. It is mainly used for cutting, grinding and brushing metal and stone. The angle grinder consists of a motor, a carbon brush, a transmission mechanism, a cutting blade, and a key. Mainly used for the grinding of steel pipes, equipment, welds and metal materials. The speed of the flat abrasive cutting disc is 11,000 rpm, and it takes 15 minutes to stop after half an hour of continuous operation. The precautions for the use of the angle grinder are as follows: 1. Wear overalls before operation, fasten the cuffs, wear protective equipment and protective glasses when working, but do not wear gloves. 2. Check if the angle grinder has a certificate and it is out of date. Check if the cornea machine can be used, whether the angle grinder has a leakage part, and the metal part of the wire has a part exposed in the air. 3, before use, we must first check the corneal film should meet the requirements, no cracks. Arranging the wire of the angle grinder should not affect the use of the angle grinder or the wire when it is working. 4, must use the corneal machine when using, do not let the cornea machine out of injury. When operating, the mind should be highly concentrated, and it is not allowed to operate while talking to people. The direction of the corneal cutting piece cannot be directed toward the person. Make sure that the corneal machine switch is in the off position before turning on the power to prevent accidental contact. 5. After the cutting piece opens the switch, it is necessary to wait for the cutting piece of the angle grinder to rotate stably before working. 6, do not use too much force when used, corneal rupture hurts, the angle of use of the cornea is generally between 30 ° to 45 °. 7. When replacing the cutting piece, make sure that the cornea machine switch must be in the off position. After the power has to be disconnected, replace the cornea. Be careful when the cornea is turned and hurt. Stop for fifteen minutes after half an hour of continuous work. If the cornea is heated during use, stop working. After the temperature drops, confirm the carbon brush wear inside the carbon brush inside the motor. If the wear is serious, the cornea must be replaced.

Abrasive belt grinding is a special form of grinding tool for sanding belts, which is tensioned by means of a tensioning mechanism, and the driving wheel is moved at a high speed, and under a certain pressure, the abrasive belt is brought into contact with the surface of the workpiece to realize The entire process of grinding. Broadly speaking, abrasive belt grinding and grinding wheel grinding are also high-speed micro-edge cutting tools the cumulative effect of micro-cutting of abrasive grains, so the grinding mechanism is basically the same. However, due to the different composition and use of the belt itself, the grinding of the belt is different from the grinding of the 12 inches cut off wheel in terms of the grinding mechanism and its comprehensive grinding performance. 1) Grinding wheel grinding is rigid contact grinding, while belt grinding is elastic contact grinding, even in the case of using inelastic steel contact wheels, because the substrate that makes up the belt is sticky. The knots have a certain elasticity, not to mention the elastic rubber as the contact wheel in most cases. Because of this, the belt grinding has the same sliding, ploughing and cutting effects as the grinding wheel, as well as the pressing action of the abrasive grains on the surface of the workpiece, and causes plastic deformation, chill layer change and surface tearing. And a combination of thermoplastic flow caused by friction causing the temperature of the contact point to rise. Therefore, from this point of view, abrasive belt grinding has multiple effects of grinding, grinding and polishing. This is also the reason why the surface quality of the abrasive belt is ground.12 inches cut off wheel On the other hand, due to the elastic grinding characteristics of the belt, the length of the belt in contact with the workpiece in the grinding area is larger than that of the grinding wheel, and the number of abrasive grains participating in the grinding is large, and the load of the single abrasive grain is applied. Small and uniform, the abrasive particles are damaged. The wear ratio of the entire belt (the ratio of the amount of grinding material removed to the amount of belt abrasive consumption is called the grinding ratio, and the reciprocal of the grinding ratio is called the grinding ratio) is much smaller than that of the grinding wheel. 2) The distribution of the abrasive grains on the grinding surface is disorderly and irregular. In actual grinding, the abrasive grains are cut with a large negative rake angle, a small relief angle or even a negative relief angle. The cutting conditions are very bad. The abrasive belt is different. The abrasive material of the abrasive belt is specially manufactured. The geometry of the abrasive grain is often in the shape of a long triangle, and it is made by a series of advanced techniques such as electrostatic sanding. The size and distribution of the abrasive grain are uniform and the contour is good. And the sharp-edged outward form is implanted on the surface of the abrasive belt substrate, and the portion where the rubberized layer is exposed is more. Therefore, the abrasive grains of the abrasive belt are sharper than the abrasive grains of the grinding wheel, the cutting conditions are good, the material deformation during grinding is small, the cutting rate is high, the grinding force and the accompanying grinding heat are small, and the grinding temperature is low. 3) The grinding wheel is filled with bonding agent, and the chip space is small. The belt space between the abrasive belts is generally at least 10 times larger than that of the grinding wheel. In addition, the abrasive grains have a high contour, so the effective cutting area of ​​the abrasive belt is large, the cutting ability is stronger than the grinding wheel, and the grinding debris can be taken away at any time. Rarely remains on the surface of the belt to cause clogging without increasing the frictional heat and the temperature in the grinding zone is low. 4) The circumference of the belt can far exceed the circumference of the grinding wheel from the design point of view, which makes the belt have a good heat-dissipating area during grinding and can pass the suspended part of the belt. The contact part of the contact wheel, the tensioning wheel, the pressing plate and the like 〉 the oscillation during operation, the grinding debris stuck on the abrasive belt is naturally shaken off, further reducing the phenomenon that the abrasive grains are stuffed, thereby reducing friction and heat generation, which is also One reason for the low grinding temperature of the belt. It can be seen that the processing mechanism of abrasive belt grinding is a more complicated form which is the same as grinding wheel grinding and different from grinding wheel grinding. This is the theoretical basis and the fundamental starting point for analyzing and understanding the grinding mechanism of abrasive belt.

From the relevant industry, we have learned that the common maintenance measures for high performance cutting discare as follows:

1. When the cutting piece is no longer sharp and the cutting surface is rough, it must be repaired in time. Grinding does not change the original angle and destroys the dynamic balance.
2. If the cutting piece is not used immediately, it should be laid flat or suspended by the inner hole. The other pieces or feet should not be stacked on the flat saw blade, and attention should be paid to moisture and rust.
3. The inner diameter correction of the cutting piece and the processing of the positioning hole must be carried out by the factory. If the processing is poor, it will affect the product use effect, and may be dangerous. The hole expansion principle should not exceed the original hole diameter of 20mm in order to avoid affecting the stress balance.
In short, only keep in mind the maintenance measures of the above special stainless steel cutting blades, in order to make it better extend its service life.

The most easily damaged in the cutting piece is the brush. When it wears, its resistance will become larger, and the electric spark will become larger, which will cause damage to the rotor. In the long run, the stator will also be destroyed, so it should be checked regularly for replacement. The replaced brush should be consistent with the previous one, otherwise it will accelerate the self-wearing. The most important thing is to match the size of the brush holder and to be tight. If it is tight, the brush is ground up. The reason is that the brush or heat is generated during work, and the heat is swollen and contracted. After the expansion, it is easy for the seat to be stuck, because the brush and the reversing piece cannot be in good contact. , thus burning the rotor. There is a locking button on the nose, and the angle grinder can be removed after pressing. Long-term application is not flexible due to dirt. It is difficult to eject after pressing. If it cannot be ejected after changing the cutting piece, it is easier to break the gear when it is turned on. In the repair, you only need to use the "oil cleaner" to spray the dust, you can have the original sensitivity.

When using customized metal cutting disc, sometimes the effect is not ideal, the thickness is not uniform, and the edge is incomplete. The main reasons for the poor performance of these resin cutting sheets in specific operations are as follows: 1. The screw of the fixed trolley screw housing is loose. At this time, the rotating screw needs to be adjusted. 2. The gap between the screw and the nut is large. The operation does not eliminate the gap. Pay attention to remove the gap in one direction during operation. 3. The resin cutting piece end is skipped large, and the saw blade needs to be tested. 4. The drive chain is too loose. 5, in the operation of the machine is not stable, there will be such a situation. 6. The main bearing clearance is too large, the spindle bearing is damaged, causing the saw blade to run unsteadily, and the radial amplitude of the saw blade is too large. These are the causes of the problem. We often use resin dicing sheets and ceramic dicing sheets, the difference between the two is that the dicing sheet has different bonding agents. In terms of the nature of the binder, the ceramic binder is an inorganic binder and the resin binder is an organic binder. Thus the properties and uses of the two cutting sheets are different: 125*1*22 EN12413 cutting disc: A dicing sheet made of a resin binder. The resin has a small shrinkage rate and a low hardening temperature, and can be made into a plurality of complicated shape cutting sheets, and can also be embedded with a reinforcing material such as a metal ring and a glass mesh cloth, so that the cutting piece has high rotation strength and can be subjected to heavy load or impact force. Working under great bad conditions. Such as high-speed heavy-duty cutting blades with a speed of 50 m / s, the load is generally as high as 5000 cattle. The resin has a certain elasticity, and the mirror-polished cutting piece made of the same can obtain a small surface roughness of the workpiece. It is also possible to form a cut or grooved cut piece of 0.8 mm or less by utilizing the plasticity before the resin is hardened. Ceramic cutting piece: The ceramic cutting piece is used to make the synthetic cutting piece, which has good stability. It can be wet-grinded by various cutting fluids during processing, and can also be dry-grinded. Ceramic cutting discs are widely used for internal and external grinding, flat surfaces, and are suitable for forming grinding and grinding of tools, gears, threads, crankshafts, etc. The ceramic cutting piece can also be made into a high-speed cutting piece, which can be used for high-speed grinding, working speed up to 60 m / s, and slow-feeding to strongly grind ceramic cutting piece, with a depth of 10 to 20 mm. The types of common resin-cut sheets on the market are: A, WA, SA, PA, GC, C, 38A, DA, and 19A. Users can choose according to their own use.

The flat abrasive cutting disc is a kind of resin grinding tool which uses special fiber fabric as reinforcing material. It is used in many fields of industry: automobile, ship, machine making and metallurgy, chemical construction and so on. The reason why there are such a wide range of applications is because of its superior performance. The cutting sheet has high tensile strength, impact resistance and bending strength, and is suitable for grinding and derusting various metal and non-metal materials, which is both rapid and economical. It has high toughness impact strength and high grinding rate. It is used for grinding, grinding and polishing. It is easy and safe to use. Most of the abrasive tools are artificial abrasives made of abrasive plus binder, and natural abrasives directly processed from natural mineral rock. In addition to the strong performance of the cutting blades, the cutting blades produced by our company are widely used in machinery manufacturing and other metal processing industries, as well as in grain processing, paper industry and ceramics, glass, stone, plastic, rubber, wood, etc. Processing of non-metallic materials. The cutting piece belongs to the grinding wheel. In the industrial production and manufacturing, sometimes it needs to be polished and cut. The cutting piece is used for the grinding of some mechanical products. It is what we need to use. An important abrasive tool, here is the safety precautions for the grinding wheel cutting piece. Nowadays, the cutting blade technology is more and more developed. The hardest part of the cutting piece should be the diamond material. It is mainly composed of the base body and the cutter head. The base body is the main support part of the bonding cutter head, and the cutter head is It is the part that plays a role in cutting during use. Need to pay attention to the process of use: 1. When replacing the cutting piece, first turn off the power supply and hang the warning sign. The cutting piece must be concentric and fastened to avoid falling off and hurting people. 2. During operation, if the cutting piece is damaged, it must be stopped immediately, and the replacement cutting piece should be replaced and then run. After the cutting is completed, first turn off the power supply, and when the cutting piece stops rotating, take the object again to avoid the flying cutting piece hurting people. 3. It is strictly forbidden to sand the objects on the cutting piece. For the use of the cutting piece, it is necessary to pay attention to the operation using a suitable method to ensure high cutting efficiency and good economical effect on workpieces of different materials.

When grinding, the axis of the grinding wheel should be equal to the axis of the workpiece to ensure the roundness of the spherical surface. The error of the contour can usually be judged based on the grinding pattern. If the surface of the ball is convex, it indicates that the grinding wheel is grinding in the lower half of the grinding wheel, that is, the center of the grinding wheel is lower than the center of the workpiece. At this time, the center position of thethin abrasive cutting disc for metal should be adjusted so that it is equal to the center of the workpiece until it is ground. The surface of the sphere has a cross-web pattern. The error is required to be within 0.003-0.004mm.
When grinding the outer spherical surface, the grinding wheel frame should be rotated at a certain angle, so the trimming of the inner hole size of the grinding wheel should be completed before the machine tool is adjusted. After the grinding wheel is blunt in the grinding process, it is not necessary to trim the inner hole. It is only necessary to trim the end surface of the grinding wheel with a sand bar, so that the grinding wheel can be restored sharply and the inner hole size of the grinding wheel can be kept unchanged. After the grinding wheel is blunt, it should be repaired in time to ensure the quality of the processing.thin abrasive cutting disc for metal Since the grinding wheel axis and the workpiece axis cannot be absolutely equal when the spherical grinding is performed, a small step is generated on the workpiece, which affects the accuracy of the workpiece. At this time, a center hole of less than 1 mm can be drilled at the top of the spherical surface to avoid.
When grinding on both sides, the two grinding wheels cannot be adjusted to parallel position
The two grinding wheels should be adjusted to an inclined angle to form a thick, fine, and light-grinding zone between the grinding wheels. The size of the feed port should be 2/3 grinding allowance for the finished product size, and the size of the discharge port should be the finished product size.
In double-face grinding (straight-through feed), the parallelism of the workpiece cannot be ignored.
1) If the accuracy of the perpendicularity of the double-face grinding machine is too poor, the accuracy of the parallelism of the workpiece will be low. The grinding head should be overhauled and calibrated to make it accurate.
2) If the feeding or discharging guide is not parallel to the grinding wheel, the parallelism of the workpiece will be excessive. The feeding and discharging layers should be adjusted.
3) If the feeding speed is not uniform during grinding, the parallelism of the workpiece will be too bad. The feeding mechanism should be checked and adjusted.
