Bearing Bushing
Descripción
The customer, a subcontractor to the German automotive industry, was looking for a suitable to chamfer the backward bore edge in a tube in a reliable and constant manner. The existing solution using a competitior's tool achieved no constant deburring result and thus caused quite some manual reworking.
Application details
Application details
In every workpiece, there are four bores of which the bore edges at the back of the bores only need to be deburred / chamfered:
- Bore-Ø d: 4 mm
- Outer Tube-Ø: 30 mm
- Inner Tube-Ø D: 26 mm
- Chamfer diam. burr free: max. 0.5 mm
- Material: Steel 1.0580 E 355
- Production volume: 680'000 bores per year
- Machine: Long turning lathe
- Processing: Radial processing from bar
- Coolant pressure: 30 bar
