How to polish the surface of abrasive molds

Polishing machine related: Grinding surface polishing technology includes four major series: cyclone type, centrifugal type, fork-shaft type, and horizontal type, as well as more than ten machine models and corresponding abrasives, slurries, and auxiliary materials. Through process testing and research on the finishing and polishing of hundreds of mechanical parts, good results have been achieved. This has yielded significant economic and social benefits.
The practical process of tumbling finishing technology is as follows:

Degreasing treatment → Polishing and deburring → Sorting → Cleaning → Drying → Rust prevention treatment

Degreasing treatment: Parts must be thoroughly degreased before finishing. Ultrasonic cleaning is the most effective method. If oil contamination enters the workpiece, the cutting force of the abrasive blocks will be significantly weakened, the abrasive effect will be reduced, the finishing effect and efficiency will decrease, and the surface of the finished parts will not be shiny.

Finishing: Finishing mainly involves selecting or determining the equipment type, equipment specifications, process materials, process parameters, etc., based on the structure, shape, size, and finishing requirements of the parts to be finished by the polishing machine.

The post-processing of finishing includes three aspects: sorting of grinding blocks and workpieces, cleaning of grinding blocks and workpieces, and dehydration and rust prevention of workpieces.

Polishing machine related: Common methods for separating grinding blocks and workpieces include manual/mechanical/vibration screening, manual electromagnetic sorting, and conveyor belt magnetic sorting. The appropriate method can be selected based on the actual conditions of the polishing machine. Ultrasonic cleaning is the best method for cleaning grinding blocks and workpieces, followed by rinsing thoroughly with clean water. Special attention should be paid to dehydration, drying, and rust prevention treatment of the workpieces.
