Polyurethane Polishing Head — Optimize CNC Automated Polishing for Metal Knife‑Mark Removal

Introduction

We are pleased to launch our high‑performance Polyurethane Polishing Head, specially engineered for CNC automated polishing operations. Designed to solve common manufacturing pain points such as residual tool marks, inconsistent surface roughness and uneven finishing on metal workpieces, this new polishing consumable delivers stable material removal performance and consistent surface quality for mass‑production workshops. As a source factory, we support rapid prototyping and full customisation to match diverse polishing scenarios across multiple industries.

Core Product Advantages

1. Efficient knife‑mark removal capability The polyurethane matrix is compounded with precision abrasive grains, achieving controlled cutting force. It effectively erases CNC machining knife marks on stainless steel, aluminium alloy and other metal parts. It helps lower Ra value steadily without generating excessive secondary scratches, greatly reducing subsequent manual polishing workload.
2. Wide‑range specification coverage

• Diameter range: 6‑100 mm
• Grit size: 60#‑5000#

From coarse grinding for heavy burr removal to ultra‑fine finishing for mirror‑level surfaces, different grit options satisfy the whole polishing workflow. Multiple head shapes and shank sizes are available to fit most CNC automatic polishing machines.

3. Stable performance for automated production Good elasticity and wear‑resistance of polyurethane material guarantee long service life during continuous CNC high‑speed running. The polishing head maintains uniform contact with complex curved surfaces, avoiding over‑grinding on edges and corners. It brings repeatable finishing results, perfectly adapting to batch automated production requirements.
4. Flexible customisation & rapid prototyping As an original manufacturer, we provide one‑stop custom solutions. We can adjust abrasive formula, hardness, shape, dimension and grit according to your workpiece material, surface requirements and machine parameters. Rapid prototyping service shortens your sample verification cycle to accelerate project iteration.

Main Application Scenarios

• CNC automatic polishing for stainless steel, aluminum alloy and other precision metal components
• Removal of tool marks, burrs and surface defects on machined parts
• 3C hardware parts, auto accessory, hardware mould and sanitary ware finishing process
• Mass‑production workshops pursuing consistent surface roughness and reduced manual post‑processing

About Us

LiChuang New Material focuses on the R&D and production of high‑end polishing and grinding consumables. We keep developing practical polishing solutions oriented to real‑world manufacturing problems. Except for standard‑series polyurethane polishing heads, we also support tailor‑made products for special working conditions.

If you are looking to upgrade your existing CNC polishing process, welcome to contact our technical team for samples and technical consultation. We can recommend suitable grit and dimension matching your actual processing conditions.
