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
Proposed solution
Proposed solution
HEULE proposed the follwing solution:
Tool: COFA 4M/4.0/Z1-OM
Blade: GH-C-M-0914-T nrs
Machining parameters:
- Cutting speed: S = 1200 min-1 / v = 15 m/min
- Feed: f = 0.2 mm/rev. (F = 240 mm/min)
Customer benefits
Customer benefits
The capabitlity of the deburring process has been proven and the manual reworking has become no longer necessary. The cycle time could be improved. This resultet in productivity gains of at least 20 %.
Customer satisfaction
Customer satisfaction
Long term member of the staff possessing a large amount of knowhow are as much excited about the results with the new tool as the head of production who can rely on a reliable solution now.
