Thread milling cutter "MGF"
Chamfering and thread milling in one operation
Significant time savings and improvements to thread production on CNC machining centres can be achieved by the use of thread milling tools which can do the chamfer and thread milling in one operation.
As a standard, we offer you two types: our thread milling cutter "MGF" with a chamfering part at the shank for thread lengths of 1.5xD, 2.0xD and 2.5xD. For other thread lengths, our universal thread milling cutter "UMGF" with rear and front chamfering tool can be used.

We offer you the thread milling cutter "MGF" in the following cutting materials:


Schematic sequence:
Chamfering and thread milling with "MGF", conventional milling
  1. Approach
  2. Countersink
  3. Withdraw
  4. Radial setting to nominal thread diameter - positioning loop
  5. Forward advance around the pitch with simultaneous rotation of the tool around the centre axis of the thread
  6. Radial movement back to the bore centre - retraction loop
  7. Reverse stroke from the finished thread bore.

Advantages:

  • Short production time due to high cutting speed and rapid advance
  • Use of standard tools to produce the core diameter, the chamfer is included on the thread mill
  • Excellent surface finish by variation of the cutting parameters
  • Exact pitch
  • Short milling chips (no chip problem compared to cutting taps)
  • Different tolerances and thread sizes can be produced (6H, 6G or M18x1,5, M20x1,5 and M24x1,5)
  • One tool for blind and through holes
  • One tool for right- and left-handed threads
  • Less tool magazine slots necessary
  • No chip rests in the bottom of the thread hole
  • Low cutting pressure when working on thin-walled pieces
  • Exact thread depth
  • Core hole and thread are exactly concentric
