Description

Technical Field

[0001] The present disclosure specifically discloses the technical field of grinding machines, and in particular relates to a high-precision machining mechanism of a fully automatic grinding machine. Background Art

[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. A grinder can process materials with higher hardness, such as hardened steel and cemented carbide, and can also process brittle materials, such as glass and granite. A grinder can perform high-precision grinding with very small surface roughness, and can also perform high-efficiency grinding, such as high-power grinding.

[0003] According to application number 202021154841.5, a high-precision grinding machine is disclosed, including an equipment body, a waste collection mechanism and a workpiece fixing mechanism. The waste collection mechanism includes a cleaning water tank, which is fixedly connected to one side of the inner cavity of the equipment body. A water pump is fixedly connected to the bottom of the inner cavity of the cleaning water tank. A shunt pipe is fixedly connected to the top of one side of the water pump through the equipment body. An atomizing nozzle is fixedly connected to the end of the shunt pipe. By setting this device, the equipment can cool down the grinding tool while cleaning the waste. By setting a cleaning water tank, a water pump, a shunt pipe, a motor output shaft, an atomizing nozzle, and a drain pipe, the equipment can effectively collect the waste generated when the workpiece is ground;

[0004] Existing grinders require manual movement of the workpiece forward and backward or left and right. When the workpiece needs to be ground on different surfaces, it needs to be clamped again, which reduces work efficiency. In addition, the existing grinding waste cannot be collected, which affects the movement of the workpiece and degrades the processing accuracy.
