Suitable for mirror polishing of precision parts such as optical molds
Diameter range: φ0.5-φ6.0mm
Arc range: R0.25-R3mm
PCD extrusion tools are low-cost and high-efficiency tools for surface mirror processing. The high-precision, finely polished diamond extrusion workpiece surface, as the applied pressure exceeds the yield point of the part material, the surface of the part undergoes plastic deformation due to the cold extrusion of the shallow material, achieving the effect of extrusion polishing.
The milling process of precision molds has high requirements for precision and surface finish, and usually requires polishing, rolling and other technology to achieve the desired effect. In line with the mission of replacing imports and helping customers improve quality and efficiency, Moresuperhard has launched a sharp tool for surface mirror processing, low cost and high efficiency - PCD extrusion tools.
Application of PCD extrusion tools:
PCD extrusions tools are ideal for machining hardness of HRC45-HRC60 materials, such as mold steel, graphite, glass, ceramics, carbon fiber, sapphire and so on.
Features of PCD extrusions tools:
* Can be used for a variety of taper, arc, outer circle and other rolling processing
* The workpiece surface roughness is less than Ra0.08
* Improved wear resistance of workpiece
* Improvement of processing efficiency
* Long tool life
* Support non-standard customization
