1. The design of grinding machine body is changed from loose frame structure to steel plate closed welding structure. It greatly improves the strength of the body and prolongs its service life.

2. For the collective welded steel plate and metal material, full vibration aging treatment technology is adopted, which can obviously eliminate the degree of natural deformation of the whole machine after processing.

3. The transmission part changes the original belt drive to rack drive, overcomes the uneven landing point of travel speed, and ensures its reliability and stability.

4. The original design that the swing rotation angle of the grinding head of the grinder is 30 to swing rotation angle greater than 90 makes it more convenient and faster to replace upper and lower workpieces and grinding wheels.

5. The design of automatic feed is adopted in grinding head processing, which improves the degree of automation. It effectively saves the manpower and time necessary for manual feeding, and improves the labor level of operators.
