Descripción

The customer, a Chinese transplant of a renowned German gear manufacturer, wanted to deburr four oil holes in a gear shaft.

Application details

Bore diameter: 3.0 mm
Material: steel
Production volume: 420'000 units p.a. / 1'680'000 bores p.a.
Machine: CNC Vertical machine center

Proposed solution

In this case, there are two possible solutions. The job could be done either by a COFA or by a SNAP tool. The unevenness of the bore edge is not too high so that the SNAP tool can handle the task too. Since the customer favoured a larger chamfer, the choice was evident.

Chamfering tool: SNAP3/3.0/10
Blade: GH-Q-M40201, Ø3.6 90°, TIN coated, front and back cutting

Machining parameters:
Working speed: 3500 rev./min.
Working feed: 100 mm/min.

Customer benefits

The customer has implemented a very cost efficient process not only because of the speed and its outspoken reliability but also because of the long tool life of the blades.

Another advantage is the very simple blade change that guarantees a most efficient servicing of the tool.
