Centerless grinding machines are a type of grinding machines that do not require the use of the axis of the workpiece for grinding. "It is composed of three mechanisms: a grinding wheel, an adjustment wheel, and a workpiece holder. The grinding wheel actually performs the grinding task. The adjustment wheel controls the rotation of the workpiece and causes the workpiece to have a feed speed. As for the workpiece holder, which supports the workpiece during grinding, there can be several ways to cooperate with these three mechanisms, except for stopping grinding, which is the same in principle.". Centerless grinding machines can automatically trim and compensate. The guide wheel feed guide rail is a dual V-shaped needle roller guide wheel fed by a servo motor that can compensate for grinding wheel dressing. The machine tool is equipped with an automatic loading and unloading mechanism, which can perform automatic circular grinding.
The development of centerless grinding machines has gone through the process of completely relying on system suppliers to initially having general development capabilities. However, the application of CNC systems is still in the stage of improving the performance of mechanical transmission chains, replacing mechanical handwheels, and simple processing cycles. Compared with advanced levels, centerless grinding machines still have many gaps, and there is a lot to improve in terms of machine tool accuracy, automation functions, processing efficiency, and reliability of centerless grinding machines Breakthrough issues need to be resolved. Summarize the various structures and use processes of various products currently produced, analyze their advantages and disadvantages, explore what automatic functions the product should achieve, and have a plan for its gradual development to facilitate learning and work; Attaching importance to the development of CNC software, centerless grinders have the conditions to introduce technology or learn from overseas, to keep up with the development trend. In terms of hardware, combined with market needs, centerless grinders will apply new technologies and new functions one by one in product manufacturing, in order to narrow the gap with advanced levels.
In the centerless grinding machine industry, to promote industrial progress. The formulation of new standards and the revision of old standards lag far behind the development of the industry. Due to changes in government agencies, industry standards have not been addressed. Given the very backward standards, it seems impractical for mindless grinders to propose creating international brands. To create an international brand of centerless grinding machines, domestic standardization work must take the lead. To further establish contacts with international standardization organizations and establish cooperative relationships based on communication, thereby improving the international competitiveness of China's product standards, creating an international brand has the foundation.
