A subcontractor for cast parts in Czechia wanted to render the production of 8 bores in a gearbox housing more efficient. Above all, the manual deburring and the related process uncertainties should be eliminated.
The proposed solution is a VEX drill-combi-tool that also takes care of the chamfering of both bore edges immediately after the drilling, in other words, in a single pass.
Tool: VEX GH-Q-O-4051
Helical drill bit: P-S-B4-0550-1A
Chamfer blade: GH-Q-M-30205
- Speed: 3500 rev./min.
- Feed: 0.08 mm/rev.
The eliminating of the manual deburring has increased the reliability of the process. 100% of the bores are deburred and in an even manner. The switch to the drill-combi tool has also led to significant savings (2 man-hours per shift).
