External cylindrical grinder is a type of cylindrical grinder with a simple structure, easy operation, and adaptability, suitable for grinding inner, outer cylindrical, and conical workpieces. It is suitable for use in workshops with single piece, small batch, and batch production. The workpiece rotation, outer circular grinding wheel, inner circular grinding wheel, oil pump, and cooling are respectively driven by separate motors. The headstock motor adopts a permanent magnet DC motor to achieve stepless speed change of the workpiece through the motor speed control plate. The longitudinal movement of the machine tool worktable can be achieved by hydraulic stepless rotation or by handwheel rotation. The lateral feed movement of the grinding wheel holder has several forms, including hydraulic acceleration movement, automatic periodic feed, and manual feed. Safety Operating Procedures for External Grind...

Talking about the wear and heating phenomena of CNC cylindrical grinding machines

2025-04-07

What factors affect the roundness of the CNC cylindrical grinder during the grinding process?During the grinding process, the clamping degree of the workpiece, whether the grinding amount is appropriate, and whether the grinding head is stable and whether there will be swinging will affect the grinding roundness of the grinder. So for these aspects, problems should be avoided in order to ensure the quality of grinding.Are the specific grinding methods the same for different CNC cylindrical grinders? Furthermore, is the working efficiency of the grinder very high?Different types or types of CNC cylindrical grinders have different specific grinding methods, so they are not the same. And for this type of grinder, its working efficiency is generally acceptable, but not very high, because it is determined by the performance of the machine itself, mainly in grinding the inner hole. ...

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...
