# Polyurethane Polishing Head for CNC Automated Deburring & Knife‑Mark Removal

Polyurethane Polishing Head for CNC Automated Deburring & Knife‑Mark Removal

Overview

Traditional post‑processing often requires manual disassembly polishing to eliminate tool marks, burrs and surface defects on metal workpieces. This method consumes abundant labor time and brings inconsistent surface quality. Our polyurethane polishing head is specially engineered for CNC in‑machine automated polishing. It realizes knife‑mark removal, deburring and surface finishing directly on the CNC machine, cutting secondary manual operations and stabilizing workpiece surface quality for mass production.

Our workshop supports rapid prototyping and full customization as a direct source factory. The polyurethane polishing head covers wide size and grit ranges to match diverse metal polishing scenarios.

Key Specifications

• Diameter range: 6‑100 mm
• Grit size: 60#‑5000#
• Mount: standard straight shank for CNC tool holder installation
• Material: high‑elasticity porous polyurethane abrasive composite

Core Advantages

1. CNC In‑Machine Polishing No need to take workpieces off fixtures. Complete knife‑mark removal and surface finishing within the existing CNC machining cycle. Reduce workpiece clamping errors and improve overall production throughput.
2. Controllable Material Removal & Uniform Surface Finish The porous polyurethane matrix delivers moderate cutting power with good surface conformability. It removes tool traces without generating deep secondary scratches. Different grit options support tasks from heavy scratch elimination to pre‑mirror fine finishing.
3. High Consistency for Mass Production Compared with hand polishing, the abrasive polishing head runs with programmed CNC paths. Every batch of parts gains repeatable surface quality, lowering reject rates caused by manual operation differences.
4. Flexible Customization Support As a source manufacturer, we offer rapid prototyping service. Customize outer diameter, thickness, shank form, hardness and grit grade according to your workpiece material and surface requirements. Custom solutions are available for aluminum, stainless steel, zinc‑alloy and other common machined metals.

Typical Application Scenarios

• Remove CNC turning & milling knife marks on aluminum alloy parts
• Deburr and finish stainless‑steel precision components
• Surface pre‑polishing for die‑cast zinc and magnesium alloy parts
• Automated finishing for consumer‑electronics structural components
• Mass‑production workshop aiming to cut manual polishing workload

Why Choose Our Polyurethane Polishing Head?
