Do you know where the performance of the centerless cylindrical grinder mechanism is worse than that of a regular cylindrical grinder?
Release time:2020-12-07
The characteristics of the centerless cylindrical grinder are as follows: compared with ordinary cylindrical grinders, the mechanism performance of the centerless cylindrical grinder has the following features.
1. Continuous processing, no need for tool return, short replication time for workpiece clamping, and high productivity.
2. The positioning mechanism of the bracket and guide wheel has better support rigidity than the top and center frame mechanisms of ordinary cylindrical grinders, with a larger cutting amount, and is conducive to the processing of slender shaft workpieces, making it easy to achieve high-speed grinding and strong grinding.
3. The workpiece of the centerless cylindrical grinder is positioned on the positioning mechanism by the outer circle, and the grinding amount is the margin on the diameter of the workpiece. Therefore, the wear of the grinding wheel, the compensation of the feed mechanism, and the repeated positioning accuracy error of the cutting mechanism have an impact on the diameter and size accuracy of the part. It is only half of a regular cylindrical grinder, does not require a center hole, and is easy to automate loading and unloading in advance.
4. The wide grinding wheel centerless grinder has a pass through mechanism that can increase the machining allowance each time. When cutting in, it can perform sequential shape grinding or multi wheel grinding on complex surfaces, with high productivity and wide applicability
There is no mechanism to ensure the relative positional accuracy (coaxiality, perpendicularity, etc.) between the grinding surface and the non grinding surface of the 5 centerless cylindrical grinder, resulting in poor roundness when grinding circumferential discontinuous outer surfaces.
6. Grinding surfaces can easily produce odd numbered edge roundness, which often creates the illusion that the measured size is smaller than the maximum physical size, affecting assembly quality and work performance.
7. Machine tool adjustment is complex and time-consuming. It is necessary to adjust the height of the bracket, distance, and related process parameters for each replacement of workpieces with different diameters. Therefore, adjusting the technology is difficult and not suitable for small batch and single piece production.
