Description

A Double Wheelhead Grinding Machine with Automatic Grinding Function

technical field

The invention relates to a machine tool, in particular to a double grinding wheel head grinder with automatic sand repairing function.

Background technique

Grinding machines are used in the field of mechanical processing. The traditional grinding machine has a compact structure and is suitable for processing workpieces with a single inner hole. It can also grind the inner hole end face and inner conical end face of the part, as well as rough and finish machining of different inner hole sizes. After the sub-process is completed, secondary clamping is required. The processing efficiency is low, and the processing accuracy is not high. The traditional grinding machine does not have the function of automatic sand repair, and the grinding wheel head needs to be disassembled for sand repair. The sand repair process leads to secondary clamping, which affects the processing efficiency and processing accuracy. In the special processing process, there will be multiple inclined processing surfaces. It is difficult to process inclined surfaces. Traditional grinding machines use tooling replacement or re-clamping for processing, which affects processing efficiency and processing accuracy.
