52-700 Solid Carbide Double Edge Upcut Spiral O Flute

Application

 

Plastic Milling

Sector

 

Plastics Fabrication Job Shop

Work piece

Material

 

TegrisTM, a 100 % polypropylene woven & laminated sheet

Machine

 

Komo 3 Axis CNC Router

Tool

 

52-702

Situation

 

Various types of 1/4" diameter tools have been tested without success.

Problem

 

This material has a low melting point and fraying of the woven fibers is common. The challenge with this material is to accomplish a good quality of cut.

Solution

 

The 52-700 has the right geometry for the polypropylene, the high rake angle of this tool sheared the fibers of the face cleanly and a 1/2" diameter was used to insure good chip flow.
