Diamond grinding cup wheel dressing principle

This method of cbn grinding wheel dressing process, high-speed rotating grinding wheel, diamond grinding wheel connected to the positive supply and the negative electrode power tools, diamond grinding wheels and tools between the electrodes is injected into the grinding coolant, voltage is applied between the tool electrode and the grinding wheel Room will spark discharge between the diamond cup grinding wheel and trim adhesive metal electrodes, temperature instantaneous discharge of the metal binder vaporized metal bonded grinding wheel surface is effectively removed, diamond grains are fully exposed to achieve wheel dressing. Features 3.2 EDM finishing trim can be achieved online, easy to guarantee the accuracy of the grinding wheel, grinding force small wheel trimmed, high-precision shaping and shaping and sharpening can be completed at the same time, but the plastic slower and EDM diamond grinding wheel dressing because the discharge temperature is too high to make abrasive performance changes, effective control of the wheel surface temperature is the key to spark a diamond grinding wheel dressing.

Electrolytic dressing method of diamond cup grinding wheel

Principle of electrolytic dressing dressing electrolysis method is mainly used for metal bond diamond cbn grinding wheel, while electrolytic dressing, metal bonded grinding wheel with a DC power supply as a positive phase electrolysis anode electrode and the DC power tool as a negative phase electrolysis cathode, between the anode and the cathode having a grinding liquid is injected into the electrolysis of the electrolytic solution as, the diamond grinding wheel, the electrolyte, the tool electrode and the power supply circuit constituting the electrolysis, dressing, so that the electrolyte filled gap between the cathode and the anode, current from flowing through the electrolyte dressing grinding wheel, the surface of the metal component metal bond diamond Plastic Base Grinding Wheel under the action of electrolytic solution agent, dissolved in the electrolyte, and the electrolyte compound hydroxide ions generated by the flow of fine solids electrolyte away, greatly reducing the diamond grinding wheel surface bond strength, this time to use mechanical trimming method, trimming performance you can get a great deal of improvement. So electrolytic dressing is dominated electrochemical, mechanical action, supplemented by a complex method of trimming. 5.2 electrolytic dressing method is characterized by the electrolytic dressing method can facilitate the realization of metal bond diamond wheel ELID and shaping and sharpening can be done at the same time, easy to control the diamond cutting wheel surface state, the advantages of electrolysis dressing diamond grinding wheel is trimmed time is short, small grinding heat, avoid dressing diamond grinding wheel due to high temperature carbide diamond cup grinding wheel life leads to decline, the disadvantage is shaping electrolytic dressing method accuracy is not high, trimming the cost of larger, more complex process.

Advantages of diamond grinding wheel dressing elastic soft law

Compared with other finishing methods, soft elastic trimming method is more suitable for finishing powder metal bond diamond wheel, because the plastic powder metal bond diamond cutting wheels both metals have high hardness, so trimming rather difficult, mainly in: dressing tool surface abrasive wear quickly, followed by trimming workers prone to clogging chip space can not continue to make dressing. The soft elastic trim Law dressing tools - when the belt is always a new sharp abrasive wheel is trimmed in contact, can form a good dressing environment, effectively removing bonded diamond cup grinding wheel surface between the abrasive and finishing mill cutting force is small, high-quality grinding surface.

Principle of diamond grinding wheel dressing law

  Has a good grinding performance on diamond cup grinding wheel industrial ceramics, carbide, optical glass, diamond tools and other difficult materials gem has a very wide range of applications. However, the presence of high hardness of diamond grinding wheel, trim rather difficult and prone to clogging and other issues in the dressing process, seriously affecting the quality and efficiency of the grinding surface dressing, limiting the application of diamond cutting wheels, a variety of diamond grinding wheel dressing article methods were compared and studied, analyzed the principles of various trim trimming methods, characteristics and use of the occasion. Dressing dressing grinding method is to use an ordinary abrasive grinding wheel and diamond grinding wheel, diamond abrasive grinding wheel rotary motion, while doing ordinary abrasive grinding wheel rotational movement also do feed movement, the role of the abrasive surface of the diamond wheel friction By slowly rotating, rotating metal bond while squeezing a certain pressure to crack the binder, with the continuous effect of friction, resulting in further expansion of the crack binder, binder eventually broken, so blunt diamond particles falling from the wheel surface, revealed sharp diamond particles so as to achieve the purpose of dressing.

The policy measures and recommendations of diamond grinding wheel industry

1, diamond cup grinding wheel industry have an objective understanding, and give due support support. Diamond grinding wheel in the national economy, although is a small industry, but indeed ranging from aerospace to almost all areas of health care and so on. Tradition, diamond grinding wheel teeth machinery industry, as it is not yet an alternative, it is indispensable. Revitalization of the machine tool industry, modernization, localization, and the rapid development of CNC grinding machine grinding machine upgrade, if accompanying traditional diamond grinding wheel can not follow up, will leave defects. Advanced CNC grinder prolonged dependence on imports of high-grade diamond cbn grinding wheel, will be upset. Therefore, we recommend that the relevant state departments of diamond grinding wheel can be placed to encourage the industry to upgrade traditional industries of the column, to give the industry and corporate research and development to support innovation and support. Industry and the establishment of joint research and joint educational research institutions, etc. to give financial support. For users to use the new high-end diamond grinding wheel prototype subsidies.

2, diamond grinding wheels for mechanical products, should be encouraged to export, the export tax rebate should be restored to 11%.

3, strictly control the scale of 8000 tons or less, using only existing technology to produce new ordinary products diamond double row cup wheel production projects; and to gain access to the national industrial policy guidance directory.

4, the proposed increase and establish industry standards for admittance, duly approved by the State to perform in order to promote industrial upgrading and accelerate the elimination of backward production capacity.

5, support industry corporate mergers and acquisitions, the state Ministry "on accelerating corporate mergers and acquisitions advice," to encourage the support of the relevant credit policy, fiscal policy and national elimination of backward production capacity.
