What Are The Uses Of A Polishing Machine?

Surface Treatment: Enhancing Aesthetics and Corrosion Resistance
The most basic function of a polishing machine is to perform micro-cutting on the workpiece surface using high-speed rotating abrasives or soft polishing wheels, eliminating scratches, oxide layers, and burrs.

Dimensional Correction and Geometric Precision Control
In precision mold processing, polishing machines play a crucial role in final dimensional correction. For example, in the plastic mold industry, mold cavities need to be controlled within ±5μm using a fluid polishing machine (utilizing high-polymer soft abrasives flow and grind under pressure) to ensure burr-free injection molded products. In aerospace blade manufacturing, five-axis linkage polishing machines can polish complex curved surfaces with a precision of 0.01mm, avoiding stress concentration caused by subsequent manual correction.

Functional Enhancement: Optimizing Material Surface Properties
Through specific processes, polishing machines can endow workpieces with special functions. For example, in the medical device field, polishing machines treat the surface of titanium alloy implants to below Ra0.2μm, reducing bacterial adhesion; in the semiconductor industry, polishing machines, combined with chemical mechanical polishing (CMP) technology, achieve global wafer planarization, ensuring lithography accuracy. The new magnetorheological polishing machine uses a magnetic field to control the flow of abrasive, which can form a nanoscale corrugated structure on the surface of optical lenses, thereby improving laser transmission efficiency.
