The carrier ring is connected via vertical guide bars to a hydraulic feed unit at the base of the machine. This controls the drilling feed rate and also provides the facility for the carrier ring to be raised up for working space when setting the machine.
The clutch facing will be drilled stepwise in groups of holes until the numeric controlled index table has completed one revolution. Then the drilled disk will be rejected and a blank one will be located in the drill position.
Clamping is hydraulically operated, using a clamp plate which comes down centring the disk between conical spikes.
The magazine feed system also works hydraulically and has no interchange parts.
All ducts for dust extraction end at the common 140 dia connection point.
The machine is equipped with a PLC SIEMENS S7.
The complete cycle consists of:
- Loading by the feeding system
- Holding-down by the clamping device
- Drilling of the first group of holes
- Indexing step
- Drilling of the next group of holes etc.
- Release of clamp at the end of the cycle
- Machine stops when set on SEMI or starts again when set on AUTO
