Descripción

Our customer, a subcontractor to a German elevator manufacturer was looking for a solution for chamfering front and back of a threaded bore without having to clamp the workpiece a second time.

Application details

Bore diameter: Ø12.0 mm
Chamfer diameter: Ø14.5 mm
Material: GG25

Proposed solution

HEULE recommended their SNAP tool out of Thread tool series SNAP5/M14 with carbide blade GH-Q-M34192 coated for more demanding requirements.

Machining sparameters:

Speed: 1100 rev./min.
Feed: 0.15 mm/rev.
Coolant: external coolant

Customer benefits

By using the SNAP Thread Tool the customer gains time, money and process capability. Key advantage is that the reclamping and readjustment of the workpiece is no longer required. This allows short cycle times and improved accuracy.
