Surface Polishing
Surface Polishing
Surface polishing services that remove machining marks and deliver mirror, satin or hairline finishes on aluminium, stainless steel, brass and copper components.
Product Overview
Surface Quality That Shows in the Finished Product
Polishing is often the final operation before a part is seen and judged. We remove machining marks progressively through grinding, buffing and final polishing, and we inspect under controlled lighting so that surface defects are caught before the parts are packed.
Zhigao is a manufacturer of surface polishing serving customers in Europe, North America and Asia. Every order is produced to your drawing and inspected against your specification before shipment, with full documentation supplied.
