Description

A self-centering fixture for CNC grinding machines

Technical Field

The utility model relates to the technical field of numerical control grinding machines, and more specifically, to a self-centering fixture for numerical control grinding machines.

Background Art

CNC grinders are machine tools that use grinding tools to grind the surface of workpieces through CNC technology. Most grinders use high-speed rotating grinding wheels for grinding, while a few use other grinding tools such as oilstones and abrasive belts and free abrasives for processing. CNC grinders include CNC surface grinders, CNC centerless grinders, CNC internal and external cylindrical grinders, CNC vertical universal grinders, CNC coordinate grinders and CNC forming grinders. Most of the existing CNC grinder self-centering fixtures cannot change the direction of the workpiece. A few CNC grinder self-centering fixtures can change the direction, but the accuracy is not high and the load that can be carried is small. For this reason, the following device is designed to solve the above problems.
