Polishing machine grinding equipment is a device used in factory workshops to deburr workpieces. It consists of basic components such as a base, a disc, polishing fabric, a polishing cover, and a lid. The weight of a polishing machine ranges from approximately 1000kg-1500kg, and some even reach several tons. Once the polishing machine equipment malfunctions, it is difficult to complete the entire repair process manually during maintenance. When repairing the bottom of the grinder, we can use a screw jack to lift the grinder.

The bottom of the grinder is the base part, and the base is a sturdy heavy-duty cast iron structure that supports other components of the machine. It houses the hydraulic oil tank and grinding wheel head assembly.

Due to its simple operation, strong load-bearing capacity, strong braking ability, and high stability, the screw jack can effectively assist maintenance personnel in lifting the bottom of the grinder, making it convenient for them to disassemble parts of the grinder base, replace parts, and perform rust removal treatment on the base.
