The customer is looking for a solution to deburr radially bores of shelves from the medical industry. The solution has to work automatically and machine front and back of the bores in one single operation. Up to now, the work has been done manually.
- Bore: Ø8.6mm
- Material: Plastics
The solution from HEULE is a COFA6 VEX-S combined tool, which has been specially adapted to the customer. In one operation and without any further tool change the bores are deburred on both sides. The used drill is a HM special drill, coated with TiN (Spade drill).
It is compulsory that the workpiece is supported during the machining. This is because of the thin plate which cannot resist the cutting pressure otherwise. If not, the plate could possibly crack. When programming is to consider that you drive an extra distance into the plus of the Z axis after drilling and deburring because when retracting the tool the shelf will not be released immediately. Otherwise there is a danger that the the drill is milling a groove into the plate.
Drilling: Working speed 3000 rev/min, working feed 0.1 mm/rev
Deburring: Working speed 3000 rev/min, working feed 0.2 mm/rev
Coolant: none, dry machining
The customer is very satisfied with the result and the reached production time. Our solution eliminates the manual deburring. Furthermore, by including the deburring into the drilling tool, the bore is produced completely in one operation. The process is done reliably by a machine.
