add to favorites Hand cone method to test the hardness of the grinding wheel Cars 2018-11-14
No Picture

The hand cone method was first applied to the hardness test of the grinding wheel in 1926. This method is relatively simple. The inspector uses a steel cone to manually insert the surface of the cut off disc for stainless steel and rotate it. The hardness and hardness of the grinding wheel are judged according to the feeling and the depth of the insertion. This method is completely based on the experience and feeling of the inspector. There is no quantitative data and the precision is low. It is difficult to quantify the graded hardness.

  Similar to this method, there is Japan's Daeue test method, which is applied in Japan, Canada, and Taiwan. The Da Yue test method belongs to the mechanical cone measurement method and is developed on the basis of the hand cone method. This method can also be applied to rough China cut off disc that cannot be measured by sand blasting.

Due to the mechanical structure, the force, the rotation angle and the like are basically stabilized, the measurement reliability is improved, and the measurement result can be quantified, which is a reasonable measurement method. Similar to the hand cone method, there is also a scratch measurement method: this aspect is similar to the definition method of Mohs hardness. In practice, a grinding wheel of known hardness is used to draw another grinding wheel of unknown hardness, according to how much the abrasive falls off. To judge the hard and soft. Japan developed it into a mechanical scratch test method, which can achieve quantitative measurement of the fixed force. The former Soviet abrasive abrasives standard stipulates that the hardness of rubber abrasives is determined by the pressure cone method. In these methods of measuring hardness, the measurement force depends on both the strength of the bonding agent and the toughness of the abrasive, so the measured hardness does not reflect the inherent hardness characteristics of the grinding wheel.

The grinder is mainly composed of a base, a grinding wheel, an electric motor or other power source, a bracket, a shield and a water heater. The grinding wheel is disposed on the top surface of the base, and the base has a space for accommodating the power source. The power source drives a speed reducer, and the speed reducer has a transmission shaft passing through the top surface of the base for fixing the grinding wheel, and the base corresponding to the bottom position of the grinding wheel has a concave water collecting area, and the water collecting area extends outward to the first-class road, the water supply 7" cut off disc for stainless steelThe device is disposed above one side of the grinding wheel, and has a space for holding water in the water feeder, and a water outlet is provided on one side of the water heater corresponding to the grinding wheel. The overall transmission mechanism is very simple and perfect, which makes the grinding process more convenient and smooth and improves the grinding efficiency of the whole grinder.

A multifunctional cutting machine base comprises a base body, a guide rail, a rail positioning buckle and a tape measure, and the base body connecting the cutting machine part and the common base adopt the same size design to ensure mutual replacement with the common base, and the base body is placed without interfering with the cutting saw The position is provided with a guide rail slider parallel to the cutting direction, and the guide rail passes through the guide rail slider 7" cut off disc for stainless steelso that the guide rail slider can only move along the direction of the guide rail, the guide rail positioning buckle is arranged at both ends of the guide rail, and the guide rail positioning buckle is provided with an adjustable clamping portion. The rail positioning buckle can be fixed on the plate of different thickness, and the tape measure is fixed on the base body and can be stretched in the vertical cutting direction.

The beneficial effect of the design is that it is more convenient to use the functions of the base guide tape measure together, especially for the woodworking, the large mechanical equipment is not good to carry, so the improvement of the manual tool can greatly improve the work efficiency and save the time cost, and the common base Can be replaced with each other so that no improvement on the cutting machine greatly improves the interchangeability of the product. Since the guide rail can be fixed, the cutting is smooth and stable, and the cutting of the ordinary base plate requires the base to be placed on the ruler for a long time. The ruler is deformed, and the product only needs to force the side of the guide rail in the cutting direction to make the guide rail straight and not deformed, thereby greatly improving the service cost and the production quality. The base body is provided with a roller that can roll in the cutting direction to reduce the friction between the cutting machine and the plate member, and the plate can be prevented from being damaged due to the heavy rolling friction of the cutting machine. The base body is provided with an adjustable positioning cutting piece so that the cutting line of the cutting piece and the edge of the positioning piece are on the same straight line, so that the wire is directly drawn on the plate and then positioned to be used by the cutting machine. The two tape measure bases are fixed on the same section of the T-shaped long hook to ensure that the tape measure can be pulled out together and can be hooked forward or reverse to the reference surface, so that the left or right side of the cutting line can be selected as the reference without cutting direction. limit.

 There are at least two positioning positions of the guide rails on the base body and respectively located on both sides of the cutting line, so that the cutting machine can cut the plates of different widths and place the guide rails on the easy-fixing side, which is convenient for cutting narrow plates.

The market is weak, the competition between the peers is fierce, and the cutting-slice industry enterprises are faced with the dilemma of low profits. The comprehensive analysis is nothing more than the following reasons: 1. There is no sound market mechanism As is known to all, the flat cutting disc on sale industry is difficult to form a relevant management mechanism due to the low barriers to entry. Although many associations and institutions in the industry have called for fair and reasonable competition, they have little effect. The traditional distribution center of cutting chip products is a systematic marketing strategy, and the lack of relevant regional protection, the stable price system is even more difficult to talk about. Once the professional market is formed, and with the strong supervision of the market, the production enterprises can be guaranteed to be worthy of the name, forming a consumer's purchase centripetal force, avoiding the phenomenon that the peers flock to, blindly produce, cause inventory, and lower prices. 2, no comprehensive brand ability The cutting piece products that are generally circulated in the market are simple in style, outdated, and have a rough workmanship, even without brand protection, so that consumers' trust cannot be obtained. According to relevant market research, 45.3% of hardware consumers use the brand as the primary demand for purchasing products when purchasing cutting products, which implies that it is even more difficult for unnamed brands to gain a foothold in the market. In this era of information redundancy, the brand is obviously a target, which can concentrate the people with fixed characteristics under their unified management, which is more conducive to the promotion of enterprises. 3. Foreign companies seize the market A large number of hardware products in China are produced in small workshops, especially in the fiber cutting disc Chinese supplier industry. Because of their lack of professionalism and exquisiteness, many foreign-funded enterprises have opportunities to take advantage of. On the contrary, foreign cutting companies are mostly “small but specialized, small and fine”; foreign famous brand cutting products make domestic enterprises far behind, so domestic cutting products are difficult to enter the high-end market, and only some services are not very demanding. Business. 4, the cost of rising public From the industry operation report of the previous two years, the main reason for the decline in profit growth in the industry is the increase in costs. The increase in administrative expenses and the increase in financial expenses were relatively large. Electricity, workers' wages, and purchase of raw materials all increased in varying degrees. Many enterprises returned funds, processed inventories, and sold products at low prices. In addition, due to environmental protection or market reasons, enterprises have to increase the cost of transformation and upgrading, and the current transformation and upgrading is not a simple furnace, the site is increased, but the quality changes, intelligent, automated and widely used, advanced The use of technology and technology has increased investment in fixed assets, increased costs, and diluted profits. Nowadays, the quality of our products is constantly improving. Many products have been able to reach foreign standards. The continuous decline in prices is caused by mutual price reduction. It is hoped that enterprises can communicate with each other and learn from each other to achieve the goal of common improvement. In the process of learning, we must digest advanced experience, we must not make hard imitation, and we must respect the intellectual property rights of R&D enterprises. This is also the basis for in-depth exchanges.
add to favorites Cutting the chip size selection principle? Cars 2018-11-13
No Picture
When selecting the particle size of the cutting piece, it should be selected mainly according to the requirements of processing precision, surface roughness and cutting efficiency. The general principles are as follows: It is required that the workpiece to be ground has a high roughness, and the coarse grain size should be selected; the surface roughness is required to be low, and the fine particle size should be selected. When the workpiece requires high geometric accuracy and low surface roughness, the mixing particle size should be selected. The geometric accuracy of the workpiece is high. When the contact area between the aluminum flat cutting disc and the workpiece is small, the fine particle size should be selected. When the contact area is large, the coarse grain size is selected. The workpiece material is hard and brittle, and the fine grain size should be selected; the workpiece material is soft and tough, and the coarse grain size should be selected. The workpiece has poor thermal conductivity, is prone to heat deformation, and is prone to burn. The coarser grain size should be selected. Cutting piece hardness selection principle? When selecting the hardness of the cutting piece, it is mainly selected according to the nature of the workpiece material and the cutting method. The hardness of the dicing sheet refers to the ease with which the abrasive grains on the surface of the dicing sheet fall off under the action of the cutting force. The hardness of the dicing sheet is soft, indicating that the abrasive grains of the dicing sheet are easily detached, and the hardness of the dicing sheet is hard, indicating that the abrasive grains are difficult to fall off. The hardness of the cutting piece and the hardness of the cutting piece are two different concepts. The same cutting piece can be made into a cutting piece of different hardness, which is mainly determined by the performance and quantity of the bonding agent and the manufacturing process of the cutting piece. The significant difference between cutting and cutting is that the cutting piece has "self-sharpness". Selecting the hardness of the cutting piece is actually choosing the self-sharpness of the cutting piece. It is hoped that the sharp grinding particles should not fall off too early, and should not be blunt. Does not fall off. The general principles are as follows: When cutting hard materials, the abrasive particles are easy to blunt, in order to make the blunt abrasive particles fall off in time, a softer cutting blade should be selected. When cutting soft materials, the abrasive grains are not easy to be blunt, in order not to cause the unburnt particles to fall off prematurely, a harder cutting piece should be selected. When cutting very soft and tough non-ferrous materials (such as aluminum and copper), in order to avoid the blockage of the cutting piece, a softer cutting piece should be used. The cutting speed of the cutting piece is low, and a hard cutting piece should be selected; the 5 inch resin cutting disc for metal has a high line speed, and a soft cutting piece should be selected. The contact area between the cutting piece and the workpiece is large, and a soft cutting piece should be selected; if the contact area is small, a hard cutting piece should be selected. When grinding a workpiece with poor thermal conductivity, deformation, and burn, a softer cutting piece should be used. In dry grinding, in order to reduce heat generation and avoid burns on the workpiece, the hardness of the cutting piece should be 1:1 softer than that of the wet grinding. When the cutting efficiency requirement is high, a softer cutting piece can be selected. When the roughness requirement is low, a harder cutting piece can be selected.

The chamfering, after a series of processes, finally becomes a qualified mechanical component. The aluminum abrasive cutting disc is used as an assistant in the processing of mechanical parts. His quality, reliability, high efficiency and safety are the focus of each machining center when purchasing. Faced with the development trend of the future machinery industry, the future machining center's requirements for cutting sheets tend to be as follows; First, the hardness of the 14 inches cutting disc, more and more new metal products in the future, then the hardness requirements of the cutting piece product are also more and more, the hardness of the cutting piece product determines everything of the product, currently, by the super hard cutting piece High precision and high efficiency grinding results have been widely recognized.  Second, the improvement of the physical structure of the cutting piece, such as increasing the number of abrasive grains acting on the workpiece per unit time, increasing the average length of the grinding, and increasing the grinding contact surface, all of which change the amount of grinding per unit time, effectively Improve the efficiency; the cutting piece that really improves the efficiency of the product can truly grasp the future market.  With the development of the machinery industry in the future, more and more cutting film companies have begun to enter this market. Many companies have begun to update their product technology, hoping to develop more products that are more suitable for the development level of the machinery industry at that time.
add to favorites Cone Crusher Realizes Full Advantage of Iron Ore Hardware - Hard disks 2018-11-13

The iron ore is the source of iron and grinding mill grinding roller driving method industry. With the rapid development of economy, China's steel industry also develops rapidly. Therefore, our demand for iron ore is increasing greatly. However, the grade of our country's grade is low. The domestic iron ore companies need to process large amount of raw ore in order to ultimately select the iron with economic value. Since the overall development level of mining equipment in China is very low, the raw ore can not be made full use. As a result, large numbers of tailings are produced in the production process, which causes great waste and loss of natural resources and energy, and immense damage to environment. The processing procedure shows that cone crusher can realize the full advantage of iron ore by further crushing the iron ore into small particle size.

At present, coal washing crushing plant equipment for iron ore processing include jaw crusher, cone crusher and ultra-crushing impact crusher. The working principles of all kinds of crushers are different and the characteristics of the processing are different. The jaw crusher is mainly used for coarse crushing of raw ore. The iron ore can be made full use through cone crusher, after which the iron ore can be crushed through impact crusher to meet the required fineness of production.

Only taking full advantage of iron ore can meet the requirements of the rapid development of iron ore, which can also make full use of other mineral resources with environmental conservation. It is necessary to constantly improve the technical level and performance advantages of crushers, which not only realizes the reasonable and perfect use of iron ore, and also plays an important role in promoting the utilization of other mineral resources.

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.

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.
