Safe-Lock™: Roughing application in the packing machine industry

Problem:

  • Only Weldon holders could be used
  • High tool wear on one flute (Tool breakout on the opposite side of the Weldon flat)

=> Target: Increase of tool life by usage of high precision tool holding instead of Weldon.

 

Target:

  • Increase of tool life by usage of high precision tool holding instead of Weldon

Application: Contour milling

Material: Steel
Cutting tool: HPC solid carbide cutter with variable flutes Ø = 20 mm, Z=4

Application parameters:

Cutting depth: axial (ap) =0.75xD, radial (ae) =10 mm
Cutting speed (vc): 180 m/min
Feed rate/flute (fz): 0.07 mm

Result:

This comparison shows the wear characteristics of the cutting tools at various machining times. Of note is that, in the case of Safe-LockTM, even at double the machining time, wear is less prevalent and more
controlled than for Weldon - with 100% protection against pullout.
