Polyurethane Polishing Head | CNC In‑Machine Automated Polishing

13 | Published by Lichuang at Aug 25, 2026

Product Introduction

Our polyurethane polishing head is purpose‑built for CNC in‑machine automatic polishing operations. It efficiently eliminates milling and turning tool marks on metal workpieces directly on the CNC machine. It cuts tedious offline manual polishing steps, stabilizes surface finishing quality and boosts overall production efficiency for mass‑volume manufacturing.

As an original source factory, we support rapid prototyping and full‑range customization. A broad selection of diameters and grit grades are available to match aluminum alloy, stainless steel and other metal polishing requirements.

Specifications

Diameter: 6‑100 mm
Grit: 60#‑5000#
Shank: standard straight shank for direct CNC tool‑holder mounting
Base material: porous elastic polyurethane bonded abrasive

Product Strengths

✅ In‑situ CNC polishing Complete knife‑mark removal and surface finishing without removing parts from fixtures. Avoid secondary clamping errors and shorten production cycles.

✅ Balanced cutting performance Moderate abrasive cutting power with good surface conformability. Remove tool traces without creating deep new scratches. Covers coarse scratch removal through pre‑mirror fine polishing.

✅ Consistent mass‑production results Program‑controlled CNC polishing delivers repeatable surface effect across batches. Reduce defect rates caused by inconsistencies of manual hand polishing.

✅ Flexible custom solutions Adjust dimensions, hardness and grit according to your workpiece material and finish target. Custom samples can be quickly developed.
