1、 The speed regulation range should be wide, and it is required to achieve stepless speed regulation within the range of 0.05-4m/min. The motion should be smooth, with no crawling at low speeds and no impact at high speeds.2、 Within the above speed range, it can automatically change direction, with a smooth switching process, minimal impact, quick start and stop, and high switching accuracy.3、 The worktable should have a certain amount of dwell time before moving forward at the end of the stroke to prevent the size of the T-piece from being too large due to short grinding time, and the dwell time can be adjusted within 0-5s.4、 The workbench can perform micro shaking, with a shaking frequency of 60-180 times/min. If the external grinder is equipped with an internal grinding head accessory, it can also grind inner holes and taper holes. ...

Analyzing the reasons for errors in CNC cylindrical grinding machines

2025-04-07

During the machining process, CNC cylindrical grinders often encounter some problems, including unstable grinding accuracy, substandard surface roughness, machine tool vibration, and wheel breakage.Unstable grinding accuracy may be caused by grinding wheel wear, incorrect installation, or unstable workpiece clamping. Regular inspection and replacement of the grinding wheel should be carried out to ensure correct installation and stable clamping of the workpiece.If the surface roughness does not meet the standard, it may be due to inappropriate grinding wheel size or improper grinding parameter settings. The solution is to choose the appropriate grinding wheel size and adjust the grinding parameters to a good state.Machine tool vibration may be caused by unstable installation, unbalanced grinding wheel, or excessive grinding force. To ensure smooth operation of the machine tool, it is necessary to ensure sta...
