Spherical Polyurethane Polishing Head for Complex Contour CNC Polishing

Release Date: September 17, 2026 Lichuang New Materials, a trusted source factory of precision grinding and polishing consumables, has launched its spherical polyurethane polishing head, specially engineered for CNC automated polishing of curved, contoured and irregular workpiece surfaces. This new polishing solution effectively removes machining knife marks and achieves consistent fine finishing on complex geometry parts.

Formulated with porous polyurethane matrix uniformly embedded with high-performance abrasive grains, the spherical polishing head features a smooth dome profile that fits seamlessly into curved cavities, rounded edges and 3D contoured surfaces. Unlike cylindrical polishing heads that struggle to reach complex geometries, this spherical design ensures even contact pressure across curved workpieces, eliminating uneven polishing, knife marks and surface burrs without over-grinding sharp corners.

Key Product Specifications

• Diameter range: 6–100 mm
• Grit options: 60# to 5000#
• Shaft-mounted structure, compatible with standard CNC polishing spindles
• Custom hardness, abrasive grades and dimensions available, rapid prototyping supported

With 18 years of material R&D experience and 8 automated production lines, Lichuang New Materials conducts strict quality inspection with laser particle size analyzers. We maintain long-term technical cooperation with Henan University of Technology to continuously upgrade polyurethane composite formulas. Our polishing consumables have been supplied to leading manufacturers including Foxconn, Changying Precision and Biel Crystal, covering consumer electronics, automotive components, semiconductor equipment and optical parts industries.

This spherical polyurethane polishing head delivers stable wear resistance and low heat generation during high-speed CNC continuous operation. It reduces the risk of workpiece thermal burn and extends service life, helping manufacturing customers streamline automated polishing workflows, shorten cycle times and cut overall consumable costs for mass production.

It works excellently on aluminum alloy, stainless steel, titanium alloy, brass, copper alloy, mold steel and quartz glass. Our engineering team provides customized polishing solutions according to your workpiece material, surface roughness target and contour shape requirements. OEM and ODM orders are warmly welcomed from global industrial partners.
