The customer, a Chinese transplant of a renowned German gear manufacturer, wanted to deburr four oil holes in a gear shaft.
- 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
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
Working speed: 3500 rev./min.
Working feed: 100 mm/min.
