What cutting tool does the CNC Machine use to milling polyurethane (no burr, good finish)? LINKUT diamond milling cutter, CVD cutter, MCD cutter with great application for milling 

polyurethane / polycarbonate materials .

Polyurethane / polycarbonate materials is a new polymer synthetic material between rubber and plastic. It has both the high strength of plastic and the high elasticity of rubber. It is a 

difficult to process material. The material itself has large elasticity and the accuracy requirement is within a few threads. The previously commonly used tools are white steel tool and 

high-speed steel tool, but the accuracy is not easy to ensure, the dimensional tolerance is also different, the roughness is not good, and burr is easy to occur. 

Turning polyurethane with polycrystalline diamond (PCD) tool has better effect. The processing of polyurethane is mainly to process the outer circle and slotting. The PCD tool  has a 

sharp edge, which is easy to arrange and cut without burr.

After machining, the size of the parts is stable and the surface roughness is high. Due to the super wear resistance of PCD materials, the size of the cutting tool remains unchanged in 

the process of machining parts, and the size and geometric tolerance of the machined workpiece are guaranteed. The roughness of products processed with PCD tools can reach 

Ra0 8-Ra0. 16. Turning, milling and boring can replace the traditional grinding process, which greatly improves the processing efficiency and processing cost.
