W 2020 Spring-groove cutter - IWD GmbH

Problem:
Every extruded material has a layer on top of its surface(so- called skins) which show differences in height and thickness depending on the extruder type. This can cause problems during the milling process like the following:

• fast tool wear in the area of the skins
  

• cracked edges or frazzling at the cover layers
  

Solution:
Through the skew of the knife-like toothing (instead of the conventional rasp cut) a cracked edge will always be pulled into the disc area to be milled. Moreover the knife-like blades provide a complete overlap of each blade to one another which leads to a longer stability time.

Advantages compared to carbide-tipped tools:

• runs rather quietly
  

• good price- / performance ratio
  

• short production time even for the most complicated forms
