New Polyurethane Polishing Head Optimizes CNC Automated Polishing for Metal Surface Finishing

Shenzhen, China – September 23, 2026 – Lichuang New Materials, a professional manufacturer of advanced abrasive and polishing consumables with 18 years of R&D experience, announces the upgraded polyurethane polishing head, engineered specifically for CNC automated polishing operations to efficiently remove knife marks and achieve consistent metal surface finishing.

Designed to address common industry pain points such as uneven surface treatment, inconsistent roughness, and short tool life during CNC machining, our polyurethane polishing head combines premium polyurethane bonding matrix with carefully graded abrasive grains. The product range covers diameters from 6mm to 100mm, with grit options spanning 60# to 5000#, allowing flexible selection from heavy stock removal to ultra-fine mirror polishing.

Core Advantages

• Excellent knife mark removal capability: Uniform abrasive distribution delivers stable cutting performance, efficiently eliminating machining tool marks on aluminum alloy, stainless steel, titanium alloy, copper alloy and other metal workpieces.
• Compatible with CNC automatic polishing: Rigid shaft structure ensures stable rotation under high-speed CNC operation, reducing vibration and improving repeatability of polishing results for mass production.
• Customization & rapid prototyping: As a source factory, we support customized dimensions, hardness, grit formulations and shaft configurations. Rapid prototyping service helps clients quickly validate new polishing processes.
• Controlled surface roughness: Paired with our precision testing equipment including laser particle size analyzers, every batch maintains stable grain quality, supporting reliable Ra value control for precision components.

Application Scenarios This polyurethane polishing head is widely adopted for polishing semiconductor aluminum cavities, automotive brake calipers, motor end covers, hydraulic valve blocks, motorcycle wheel hubs, stainless steel flanges and precision hardware parts. Our products have been supplied to well-known manufacturers including Foxconn, Longcheer and Biel Crystal, with proven performance in mass production lines.
