New Polyurethane Polishing Head Optimizes CNC Automated Polishing for Precision Workpieces

Our company is pleased to announce the launch of upgraded polyurethane polishing heads, engineered to resolve common surface finishing challenges in CNC automated polishing processes for metal and hard material components.

With 18 years of material R&D experience and 8 dedicated production lines, we maintain strict quality control with laser particle size analyzers in our laboratory, and we carry out joint material research with Henan University of Technology. Our polishing consumables have been widely adopted by well-known manufacturers including Foxconn, Changying, and Biel Crystal, serving precision finishing requirements across multiple industries.

The polyurethane polishing head supports customizable dimensions ranging from 6 mm to 100 mm, with abrasive particle grades covering 60# to 5000#. It is specially formulated to efficiently remove knife marks left by CNC machining on workpieces, delivering consistent surface roughness without over-grinding or edge burning. The flexible polyurethane matrix holds abrasives uniformly, maintaining stable cutting performance during long-cycle automated polishing.

This product fits a broad range of workpiece materials: stainless steel, aluminum alloy, titanium alloy, brass, copper alloy, mold steel, gold, quartz glass, sapphire, and optical glass. Typical application scenarios include semiconductor aluminum cavities, hydraulic valve blocks, motorcycle wheel hubs, stainless steel pump bodies, automotive engine housings, and stainless steel food processing equipment.

As a source factory, we support rapid prototyping and full customization of shape, hardness, grit size and shank specifications to match customers’ CNC polishing stations. Our technical team can provide on-site process consultation to help customers reduce polishing cycle time, lower consumable replacement frequency, and improve finished part yield.

We keep advancing abrasive material innovation to meet the growing demand for high-precision automated surface treatment. Contact our sales team to request samples and process testing for your polishing projects.
