In recent years, the development of cutting machine technology has continuously increased its spindle speed and feed rate, so that it can achieve rapid cutting with higher cutting speed, greater material removal rate, and higher precision. Tools like superhard materials put forward more demands. Only a few years ago, the spindle speed of some machine tools was only 6,000r/min, but now it has reached 30,000 to 40,000r/min, and the axis movement acceleration can reach 2G. With the support of powerful computer capabilities, this machine tool can realize the motion functions required for processing. In order to convert this speed advantage into a machining advantage at the point of action, it is necessary to use the corresponding tool material. However, if you use cemented carbide tools, the cutting speed can only reach 400m/min; while the cutting speed of PCD tools can reach as high as 3,000m/min. In addition to higher processing speeds, the main advantages of PCD and PCBN tools include longer tool life, and in most cases better surface quality, reduced tool changes, and reduced non-motorized man-hours.

The grinding wheel is a necessary tool for the grinding machine. To make the grinding wheel grind to an accurate size and smooth surface, it is necessary to prevent vibration during the grinding process. The structure of the grinding wheel is composed of a large number of unevenly distributed particles, and the inherent imbalance cannot be avoided, which will inevitably cause a certain eccentric vibration. The eccentricity of the grinding wheel installation, the uneven thickness of the grinding wheel, the imbalance of the spindle and the adsorption of the cooling liquid by the grinding wheel will increase the vibration.

The strength of diamond is an important index to ensure the cutting performance. High strength will make the crystal is not easy to break, the abrasive particles are polished in use, sharpness decreased, resulting in deterioration of tool performance; When the strength of diamond is not enough, it is easy to be broken after impact and difficult to undertake the heavy cutting task. Therefore, the strength should be between 130 and 140N.

Having been in the machining industry for many years, you must be no stranger to tool failure.
Tool failure will affect machining accuracy and productivity, operator safety, and part quality.
When tool breakage is observed, the machining process should be carefully analyzed in time to find the root cause.

The processing of the sliding valve hole of the automobile automatic transmission valve body is the most demanding station in the whole box hole processing technology. In the common processing of aluminum alloy valve bodies with silicon content between 8% and 16%, MORE usually adopts a combination of two tools: "first rough and then fine processing".
