Working principle of automatic loading and unloading CNC cylindrical grinder

2025-04-07

Automatic loading and unloading CNC cylindrical grinder is a grinder that processes the outer surface and shoulder end face of cylindrical, conical, or other shaped lines of workpieces; Widely used, capable of processing various cylindrical conical outer surfaces and shaft shoulders.This CNC cylindrical grinder is mainly used for grinding cylindrical and conical surfaces. There are two basic grinding methods: longitudinal grinding and cutting in grinding. During longitudinal grinding, the grinding wheel rotates as the main motion, and the feed motion includes: the workpiece rotates for circular feed motion, the workpiece moves back and forth along its axis for longitudinal feed motion. At the end of each longitudinal or reciprocating stroke of the workpiece, the grinding wheel periodically performs a transverse feed motion, and all excess is gradually ground away in multiple reciprocating strokes.When cutti...

How to improve the precision of cylindrical grinding machine

2025-04-07

External cylindrical grinding machines are widely used in the bearing industry, and their development is particularly prominent in the automotive and motorcycle industries. It is based on the contour shape of the processed workpiece, using many straight lines and arcs to form the outer contour of the grinding wheel. By analyzing machine tools, understanding the causes of machine tool failures and errors is beneficial for improving the precision of machine tools.There are five measures to improve the precision of cylindrical grinding machines:(1) Reduce the original error. Identify the causes of errors, eliminate and reduce them;(2) Compensate for the original error. Artificially creating some errors to offset the original errors;(3) Transfer the original error. Transfer geometric errors, thermal deformation, etc. in the process system;(4) Divide the original error equally. Divide the error into several part...

The reason for the ripples on the surface of the finished product of the cylindrical grinder

2025-04-07

The reasons for causing ripples on the surface of workpieces processed by cylindrical grinders are as follows:1. Static balance difference of grinding wheel;2. If the hardness of the grinding wheel is too high or the viscosity of the grinding wheel is uneven, the grinding wheel becomes dull, the friction between the grinding wheel and the workpiece increases, and the periodic vibration of the workpiece increases;3. The main bearing of the grinding wheel is worn, and the large clearance of the main shaft causes floating during rotation, resulting in imbalance and vibration of the grinding wheel;4. Poor contact between the taper hole of the flange of the external grinding wheel and the taper end of the grinding wheel spindle can cause the grinding wheel to bounce during grinding;5. The vibration of the grinding wheel rack motor is caused by the transmission belt being too tight, loose, or uneven in length;6. ...
