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.

The needs and development of Ghana Gold Crusher in China heavily depends on the state investment in fixed assets. Since the reform and opening up, China’s fixed asset investment has got rapid growth, which has driven the boom of investment in mining machinery industry. In recent years, China has taken measures to control the investment in fixed assets, but it doesn’t have big influence on the mining machinery. The investment in mining machinery industry is increasing continuously. In 2002-2009, the fixed assets in mining machinery have kept steady growth, which has shown that the returns on capital in mining machinery industry are higher than the social average assets. So the mining machinery is worth the investment.

From the current situation of domestic mining machinery market, the foreign capital has stepped up its investment in China. The world largest engineering machinery manufacturer Caterpillar Inc has announced that it plans to invest $10 billion in China’s engineering machinery market. Domestic enterprises are facing severs challenges.The document formulated by the state to promote industrial structure optimization and upgrading in the “12th five year plan” stressed the need to improve the level of domestic production of major technical equipment. The countries will strengthen the policies to support the high-efficiency and clear power generation and transmission, large-scale petrochemical, transportation equipment, high-level CNC machine tools, automation control, integrated circuits, and advanced power devices industry. It can be inferred that the market will be further concentrated to large enterprises with the development of future mining machinery and the deepen competition in the jaw crusher and other industries. The strong will get stronger and the weak will get weaker. The domestic enterprises need to relay on their own forces to compete with multinational companies.

No Picture
This paper only analyzes how the raw materials are mainly phenolic resin and glass fiber mesh affect the quality stability of the resin grinding wheel. The most outstanding quality stability of resin grinding wheels is as follows: (1). The change of product strength and cutting performance of resin grinding wheel within a certain period (under normal air temperature and humidity conditions); (2). The change of the strength and cutting performance of each grinding wheel of the resin grinding wheel during the production cycle (such as different seasons in a year). Both of the above cases can be expressed by the measured strength retention rate and the thin flat cutting disc performance reduction rate. The influence of raw materials on the quality stability of resin grinding wheels is mainly reflected in: (1). Liquid phenolic resin. The fluctuation range of solid content, viscosity, gel time and water solubility of liquid phenolic resin has different degrees of influence. Therefore, the grinding wheel manufacturer must combine its own mixing, molding and hardening process characteristics according to its own product performance requirements. , develop the technical indicators and scope of liquid resin suitable for you. In addition, the liquid phenolic resin must be properly stored because the liquid phenolic resin is inherently unstable, and the specifications will change even at room temperature. The grinding wheel manufacturer must store the liquid phenolic resin under low temperature conditions to ensure the stability of the liquid phenolic resin, thereby ensuring the stability of the resin wheel mixture and ensuring the stability of the resin wheel quality. (2). Powder phenolic resin. For powder phenolic resins, flow length (fluidity), particle size (grain size, fineness), urotropine (six times) content and gelation time fluctuations all affect the quality of the grinding wheel. In this regard, the flow of the flow should be considered first. These indicators illustrate the behavior of the resin under certain experimental conditions. They are only the performance of the resin, and the extent of the impact on the performance of the grinding wheel can only be determined by the actual application of each resin wheel factory. The flow of the powder resin is the most important performance index affecting the structure of the binder. The particle size (grain size, fineness) affects the amount of the wetting agent, and the content of the volatiles (free phenol, water) is also important. In the actual grinding wheel production process, it is necessary to ensure the stability of the performance of each batch of powder resin, so as to ensure the quality of the grinding wheel. (3). Stability of the technical indicators of the mesh The mesh was originally applied to the resin wheel and the most important role was to increase the strength of the wheel. As the performance of the resin grinding wheel continues to increase, the role of the mesh in the resin grinding wheel is very important. Mainly manifested in: fluctuations in the strength of the grinding wheel, deformation of the slice (mainly double-wire grinding wheel), delamination of the grinding plate, and so on. The thickness of the mesh has an influence on the strength and viscosity of the cutting disc for stainless steel and the cutting and grinding performance of the resin grinding wheel. In theory, under the condition that the grinding wheel production process is stable and allowed, the mesh with the higher amount of glue, the grinding wheel The higher the strength, the better the bonding performance and the more stable the cutting.

There are many quality problems in the production process of resin grinding wheels. Since the manufacture of 12 inches cut off wheel is a multi-disciplinary synthesis of composite materials, the causes are complicated and numerous. Raw material problem Resin grinding wheel is a complex system composed of a variety of main and auxiliary raw materials. As long as the material is abrasive and bonding agent, the auxiliary material includes filler, reinforcing material, coloring agent and the like. 1. Problems that should be concerned about abrasives At present, the quality of abrasives on the market is uneven, mainly as follows: (1). The chemical composition of the abrasive is often qualified, but the physical properties are poor; mainly due to the gap between the bulk density of the abrasive and foreign countries. (2). The particle size composition of the abrasive is chaotic, which is quite different from the standard specification; it is mainly manifested in the difference between the basic particle content of the same grain size abrasive and foreign countries. 2. In terms of binder, mainly phenolic resin: (1). Resin quality stability problems, especially the level of free phenol in the resin. Excessive free phenol content will accelerate the cracking of the resin after heating and hardening of the resin wheel, affecting the strength of the grinding wheel; (2). Mixing uniformity of resin powder and urotropine, urotropine as a hardener of resin, insufficient addition of urotropine, incomplete hardening of resin, affecting the strength and hardness of the grinding wheel; Excess urotropine does not combine with the resin, and decomposes and volatilizes during the hardening process, which increases the pores of the grinding wheel and reduces its strength and hardness. (3). The binder particle size is too thick or too fine: It is generally believed that the particle size of the binder is fine, which is advantageous for uniform distribution of the binder. If the particle size is too coarse, the molding material is not easily mixed uniformly, which affects the hardness and strength of the standard cut off wheel for metal. Even for the coarse-grained resin sheet cutting wheel and the shaped grinding wheel, the size of the binder (resin powder) selected should be finer than 320#. However, if the particle size of the phenolic resin powder is too fine, the mixing is difficult, and the uniformity of the mixture is difficult to be achieved, thereby affecting the cutting performance of the resin grinding wheel.

Some common sense before choosing and using diamond cutting blades Before choosing and using China cutting disc for metal, users must understand the following common sense about low price disc for metal : 1. The difference between CVD diamond coating and amorphous diamond coating Amorphous diamond (also known as diamond-like carbon) coating is a carbon film deposited by PVD process. It has a part of diamond SP3 bond and a part of carbon SP2 bond; its film hardness is very high, but lower than the hardness of diamond film; its thickness is also thinner than the diamond film we usually deposit. When processing graphite, the life of amorphous diamond coated tools is 2 to 3 times that of uncoated cemented carbide tools. In contrast, CVD diamond is a pure diamond coating deposited by CVD process. The tool life of processing graphite is 12 to 20 times that of cemented carbide tools, which can reduce the number of tool changes and improve the reliability and accuracy of processing. consistency. 2, can not use hard diamond tools to process hardened steel Diamond is composed of carbon atoms. When some materials are heated, they absorb carbon atoms from the diamond and form carbides in the workpiece. Iron is one of these materials. When machining iron-based materials with diamond tools, the heat generated by the friction causes the carbon atoms in the diamond to diffuse into the iron, causing the diamond coating to fail prematurely due to chemical wear.

How to use the thin flat cutting disc correctly 1. The correct choice of cutting machine should pay special attention to the power, speed, rigidity and precision of the cutting machine. ¢150 below the diamond saw blade should be used 1 ~ 1.5KW, speed 7255 ~ 14500r. pm adjustable speed cutting machine, ¢ 150 ~ 230 saw blade should use 1.5 ~ 3KW, speed 4000 ~ 11000r. pm adjustable speed cutting machine; The diameter stone saw blade should be 15HP (electric) or more, the line speed is 20~60m/s, and the speed cutting machine should be used. The medium diameter engineering saw blade should be 30HP (electric) or 55HP (gasoline or diesel power) or above, and the line speed is 35~. 70m/s adjustable speed cutting machine; the power of large-diameter saw blade cutting machine is related to the diameter and number of saw blades. For example, the domestic general ¢1600 single-piece sawing machine has a power of 37~45KW and a speed of 270~360r.pm. 2. The correct installation of the diamond circular saw blade and the installation accuracy are closely related to the cutting efficiency, cutting quality and service life of the saw blade. After installation, ensure that the saw blade runs smoothly during the cutting process without vibration (except for the quality of the saw blade itself and the rigidity of the cutting machine). When installing the saw blade, first make sure that the direction of the cutting edge indicated on the saw blade is the same as the direction of rotation of the cutting machine spindle; to clean the surface where the saw blade mounting hole, the cutting machine spindle and the flange are in contact with each other, it is necessary to ensure that they are cleaned. The contact between the flat and good; the diameter of the flange should be reasonably selected according to the diameter of the saw blade. If the cutting disc for stainless steel is too small, the end face of the saw blade will be large when the flange is too large. If the flange is too large, the weight of the spindle will increase, which will increase the runout and reduce the processing depth of the material. After installation, the blade and flange must have the specified value to reach the specified value.

Grinding wheel classification: According to different abrasives, the grinding wheel has ordinary abrasive grinding wheel (corundum grinding wheel and silicon carbide grinding wheel), natural abrasive grinding wheel and super-hard abrasive grinding wheel (diamond and cubic boron nitride CBN, etc.); According to the shape, it can be divided into flat grinding wheel and special-shaped grinding wheel (beveled grinding wheel, cylindrical grinding wheel, dish-shaped grinding wheel, bowl-shaped grinding wheel, cup-shaped grinding wheel, etc.); according to different bonding agents, it can be divided into ceramic bonding material grinding wheel and resin bonding material grinding wheel. Rubber bond grinding wheel, diamond bituminous bond grinding wheel, etc. The main factors affecting the characteristics of the grinding wheel are abrasive, particle size, hardness, binder, shape, size, and tissue number. Usually, the grinding wheel is running at high speed, and the necessary inspection should be carried out on the thin abrasive cutting disc for metal before use; the rotary inspection (ensure that the grinding wheel will not burst at the highest line speed); the balance test, the static balance and the dynamic balance test (to prevent the grinding wheel from working) Causes machine tool vibration); After a period of use, the grinding wheel should be trimmed to maintain its grinding efficiency and self-sharpness.
