Accessories / Special Features:
* Machine is at present set up for high precision drilling of injection pump parts (approx. Ø 25 x 150 mm, bore approx. 5 mm). Parts are conveyed via an inclined conveyer belt in to a 2-position alignment station where the position is checked. The parts are then conveyed automatically and in pairs via a loading portal (2 x double grippers), which is mounted at a right-angle to the machine, into the working zone where they are clamped between the drill bushing holder and the motor-driven tailstock. When work is finished, the second gripper pair carries the workpieces into a blowing-out and testing station for drill breakage. After positive assessment the parts fall into a transportation container.
* SIEMENS Model OP 17 SPC Control for cycle programming and supervision.
* 2 cooled and oil-mist lubricated FORTUNA high speed spindles, capacity approx. 2 / 3.5 kW.
* Drilling slide feed via DC motor and ball screw spindle.
* Separate drilling oil unit, approx. 1,500 litre, with various pumps and an extensive band filter cleaning system.
* Separate hydraulic unit, approx. 10 kW.
* Separate BKW Coolant Unit for cooling spindle and hydraulic oil.
* 2 separate switch and control cabinets with CE mark.
