add to favorites New development of diamond grinding wheel Cars 2019-01-20
No Picture
Diamond grinding wheel is a special tool for grinding hard and hard materials such as cemented carbide, glass, ceramics and precious stones. In recent years, with the rapid development of high-speed grinding ultra-precision grinding technology, higher requirements have been placed on the 12 inches cut off wheel. The ceramic resin bond grinding wheel can no longer meet the production needs. The metal bond grinding wheel has high bonding strength and good formability. Production has been widely used due to its long service life and other significant characteristics. The metal bond diamond grinding wheel mainly has two types of sintering and electroplating depending on the manufacturing method. In order to give full play to the role of super-hard abrasives, foreign countries began to develop a new type of grinding wheel by high-temperature brazing process from the early 1990s, that is, single-layer high-temperature brazing super-hard abrasive grinding wheel. 1. Ceramic diamond grinding wheel Ceramic bond diamond grinding wheel has the common characteristics of diamond and ceramic bond. Compared with ordinary corundum and silicon carbide grinding wheel, it has strong grinding force, low temperature during grinding and relatively small wear of grinding wheel. It can adapt to various coolants. The role of the grinding wheel during grinding is good, the precision of grinding the workpiece is high; there are more air holes in the grinding wheel, which is good for chip removal and heat dissipation during grinding, not easy to block, not easy to burn the workpiece; self-sharpening of the grinding wheel The sex is better, the trimming interval is longer, and the trimming is easier. Therefore, the use of ceramic bond diamond grinding wheels in some developed countries abroad is increasing. 2. Sintered diamond wheel The sintered metal bond grinding wheel is mostly made of a metal such as bronze as a bonding agent, and is manufactured by a high-temperature sintering method. The bonding strength is high, the formability is good, the high temperature resistance, the thermal conductivity and the wear resistance are good, the service life is long, and the load can be withstood. Because the grinding process of the grinding wheel inevitably has shrinkage and deformation, the standard cut off wheel for metal must be shaped before use, but the dressing of the grinding wheel is difficult. Nowadays, the common grinding wheel rolling method is not only time-consuming and labor-intensive, but also the diamond particles fall off during the dressing process. The dressing wheel itself consumes a lot and the shaping precision is low.

As an operator skilled in the use of sand making machine, there is a way to increase the production of sand making machinery in the same environment. Therefore, mastering some basic methods of operating equipment can improve work efficiency and thus improve the production efficiency of the enterprise. First, the sand making machine needs to pay attention to the tightness of the power transmission belt during the normal operation. If the conveyor belt is too loose during use, it will affect the power transmission of the motor to the sand making machine. At this time, the production volume will naturally decrease, and the conveyor belt will be too loose and the machine will be destroyed. Therefore, in normal use, it is found that the belt is loose, and it is necessary to strengthen it in time. Second, the habit of regularly checking the internal components of the sand making machine should be developed. For example, the internal parts of the sand making machine and the impeller are all inspected regularly. There are also some other wear parts. The wear is more common and should be replaced in time. If some wear parts of the sand making machine are worn on one side and the other side is light, the balance of the machine will be affected and the damage to the machine will be great. Therefore, when these parts are found to be worn, they must be replaced in time. However, you should pay attention to when replacing the parts. When replacing the parts, you must replace them at the same time to ensure the weight of the two sides is the same; otherwise, the parts will still be damaged due to the imbalance of the two sides. Third, to ensure the normal operation of the spindle of the key components of the sand machine balance is very important. The spindle components of the sand making machine are easily worn, so the time interval for periodic inspections is shortened. According to the experience of Yamatake mechanical technicians, it is appropriate to replace the spindle of the sand making machine every 7200 hours. During this time, the spindle can be cleaned at regular intervals and then added to the lubricant. The above points are summed up to compare the effective ways to increase the output of the sand making machine. The production efficiency of the sand making machine equipment is improved, so the efficiency of the enterprise can be good. More importantly, these methods can extend the life of the sand making machine and save the production cost of the enterprise.

Each year, a considerable number of (heavy) quantities of various galvanized steel sheets are imported. Commonly used imported galvanized sheets are hot-dip galvanized sheets, electro galvanized sheets and galvanized lacquered sheets. Among the imported galvanized sheets, there are high-quality grade (first-grade) galvanized sheets, and non-premium grade galvanized sheets, so-called “second-class products”. In these different quality goods, external claims may occur; on the other hand, the import tariffs of high-quality steel products and non-quality goods are not the same. In the daily inspection or customs clearance work, it is often reported as non-quality products. As an inspection and quarantine department that inspects the quality of goods, we should pay attention to quality control, and also promote market economy and trade, and safeguard national interests and customs interests. At present, there is no standard for the inspection and identification of non-preferred grades of galvanized steel sheets in China's current national standards or production country standards or international general standards. Generally, the inspection and identification of non-quality galvanized steel sheets are based on the standards of similar quality products. Therefore, in the practice of steel inspection, exploring and mastering the correct inspection methods and inspection scales to determine the quality grade of the goods, and summarizing a set of effective empirical methods in practice will be of great significance to the inspection and quarantine work.

1. Please check carefully before installing the cutting wheel to confirm whether the cutting wheel is deformed, cracked or collapsed. 2. When the flange is too small or the precision is poor, the fiber cutting disc Chinese supplier is easily damaged. Please use it after improvement. 3. When the cutting wheel is marked with the direction of rotation, it must be in the same direction as the machine. On the contrary, the cutting is not sharp and it is difficult to perform the performance of the cutting wheel. 4. If a cutting wheel that does not match the cut workpiece is used, it is prone to abnormal wear, poor sharpness, abnormal heat, and the like. 5. If an abnormality is found during the cutting process, stop immediately. 6. When the cutting is not sharp, the grinding wheel should be trimmed. If it continues to be used, it will cause overheating and overloading and damage the grinding wheel. 7. In the rotation of the grinding wheel, it is strictly forbidden to cut by hand, and it is not allowed to touch the grinding wheel by hand or body. 8. The cutting wheel is strictly prohibited for operations other than grooving or cutting, to avoid abnormalities due to uneven force. 9. The surface quality and cutting performance of the workpiece are mainly related to the abrasive grain size of the durable cutting off wheel. The finer the particle size, the better the surface finish. At the same time, it is also related to the workpiece material, hardness, cutting amount, machine tool conditions, processing requirements and other factors. 10. The ultra-thin cutting wheel has been shaped and edged before leaving the factory and can be used directly by the user. If the user needs further shaping, it is recommended to use green silicon carbide or white corundum whetstone. The particle size is larger than the size of the cutting wheel. If the user needs to further sharpen or use a section of the blade, it is recommended to use green silicon carbide or white corundum. Whetstone, the size of the cutting wheel is finer than the size of the cutting wheel 1-2 or the same number.

Diamond ultra-thin cutting wheels are mainly used for precision grooving and cutting, and generally adopt deep-cut slow-feed grinding method. The utility model has the advantages of large grinding depth, small feed speed, large contact area between the thin flat cutting disc and the workpiece, narrow slit, high metal removal rate, high grinding precision, good processing surface quality and high material utilization rate. The general rules are as follows: 1). The integral cutting wheel is thin (more than 0.5mm), small outer diameter (20-100mm), fine grain size, high dimensional and dimensional accuracy, light weight, and generally used under high speed conditions. The general speed is 5000-40000 rpm. 2). The base type cutting wheel is mostly thick (0.5-2mm), large in diameter (100-200mm), coarse in grain size and low in precision. It is generally used under the condition of lower speed and deep depth of cut. The general speed is 3000-10000 rpm. 3). Ultra-thin cutting wheels use fine particle size, and generally the thinner the thickness of the abrasive, the finer the grain size will be, and the surface quality will be better. However, the finer the abrasive grain size, the corresponding cutting sharpness decreases, and the feed rate is correspondingly reduced to accommodate the machinability of the abrasive grain size. 4). The cutting depth of the ultra-thin cutting wheel is generally determined by the user according to the cutting part. Most of the cutting is made by the slow-feed grinding process, and the depth is cut once. In this way, since the cutting wheel is thin and the cutting conditions are poor (the three sides are in contact with the workpiece), it is difficult to dissipate heat, so it is necessary to increase (flow, pressure) cooling of the cutting zone. 5). When the cutting wheel is used immediately when the user is used on the machine, it is recommended to increase the cutting speed or reduce the feed rate. When the cutting wheel is used for a period of time, it is recommended to use it. The appropriate particle size of the oil stone is used to sharpen the surface of the cutting disc for stainless steel to adjust its sharpness. 6) The cutting amount is generally related to the material to be processed, hardness, precision, processing requirements, etc. It is recommended to use it under the original conditions of the user when using it for the first time. Do not change the cutting amount easily. 7) The user's use condition is also the main factor affecting the cutting performance. In particular, the spindle axial movement, radial runout, flange parallelism and dynamic balance accuracy of the machine tool directly affect the cutting precision of the cutting wheel.

Guide: The cutting of the cutting piece depends not only on the cutting piece itself, but also on the use of the machine tool, the connection of the 12 inches cut off wheel to the machine tool, the tool holder system of the cutting piece, the dynamic balance of the cutting piece, the safety monitoring system of the cutting piece, etc., and the cutting The film-related technology has also made new progress with the advancement of science and technology along with the cutting chip technology. Cutting blade holder system for high speed cutting CNC machine tools such as machining centers have always used the traditional 7:24 solid taper shank tool system. Due to the combination of the taper and the taper, the joint rigidity of the shank and the spindle is low. The spindle speed exceeds 10000 r/min. The shortcoming is more obvious. For the tool change with the ATC tool holder, the radial dimension of the cutting piece may change after each tool change, and there is a problem of low repeatability. To solve these problems, the standard 7:24 tool holder is mainly improved. Inspired by the HSK tool holder, a new type of coupling technology with a 7:24 tool holder has emerged in recent years. For example, Japan Nikko Co., Ltd. and Dazhaohe have developed three types of contact (3LOCKSYSTEM) and double-sided (BIGPLUS) 7: 24 joint holders. Compared to standard 7:24 shanks, they have higher joint rigidity and precision for high speed, high efficiency cutting and are compatible with existing 7:24 shanks or machine tools, which is a 7:24 shank for the future. In the development direction, in addition to the modification of the standard 7:24 shank structure, the new HSK shank and KM shank are mainly used. The HSK shank is a new type of high-speed tapered shank. The interface adopts the method of simultaneous positioning of the tapered surface and the end surface. The shank is medium-sized and the length of the cone is short, which is beneficial to realize the light-weight and high-speed of the tool change. Due to the use of end face positioning, the axial positioning error is completely eliminated, making high-speed and high-precision machining possible and also the development direction of cutting blades manufacturing in our domestic manufacturing plants. The technology of connecting high-speed standard cut off wheel for metal and spindles will continue to develop with the advancement of science and technology, and some new concept holders - HSK, KM, 3LOCK, BIGPLUS and other tool holders will be further improved and improved. The current development direction of the main shaft and cutting blade connection technology is: (1) adopting a double-sided positioning system; (2) High clamping precision, good clamping rigidity and compact structure; (3) the handle with balance and vibration damping device; (4) Develop multifunctional and intelligent tool holders.

Cooling device is the indispensable part in the Stone Crushing Equipment Sale operation process of ball mill. Fine cooling effects can be achieved by adding cooling device to the whole set of ball mill. The temperature of cooling device can be set according to the concrete production requirements so as to coordinate and supplement the insufficiencies of other cooling measures. Therefore, ball mill is favored by most customers. Colling machine makes up the shortages of relevant measures; meanwhile, there are also certain disadvantages for colling device . In the wide and long-term usage, the colling equipment of ball mill is checked all the time.

The Safety Guarantee Impact Crusher working process and state are recorded all the time so as to make the technicians to research and contrast the features of colling equipment of ball mill. 1. Single function. It only can be used to coll the temperature of material. It doesn't have any effects on the dehydration of similar materials. 2. High cost. High cost will be spent on the application of colling machine of ball mill. Meanwhile, the dosage is relatively higher when colling machine is used. 3. Security risk. The colling machine will be abraded when the materials stay in the colling machine for a long term. Therefore, the security risk such as water leakage may exist.

Laboured work. The supporting machines of ball mill require that the particle purity of materials discharged from the colling machine is higher. However, colling machine cannot finish its work under this circumstance. At the same time, integument will form on the internal surface if the colling machine works for a long time, thus the utilization efficiency of colling machine will be greatly reduced. Limited usage. Because the installation of colling machine should be coordinated with other machines especially the welding work is difficult in working process of the large-scale ball mill, the limitation exists in the application process. As for these insufficiencies, we hope that more theories and researches will solve them to make colling machine exploit its advantages to the full. In order to better improve the colling measures, we will do their best to make research to solve these problems.
