Cam shaft mechanism
A cam shaft activates the draw bar, both for locking and pushing out the cutting head. Only 1/2 turn is needed to lock and unlock. The cam shaft has a self locking angle on the surface and will not open up during machining, even despite heavy, interrupted cuts. This mechanism is used in most manual clamping units for turning, but also for flange mounting on DIN2079 spindles.
Quick screw mechanism
The movement of the drawbar is controlled by a quick-thread (two start) screw acting from therear of the unit. 1 turn is required to lock/unlock the cutting head. The mechanism is used in thetype 2000 manual clamping unit for turning.
Hydro-mechanical mechanism
On automatic clamping units for turning, hydraulic pressure is used to activate the forward and backward movement of the drawbar. | |
| The clamping mechanism is mechanically self-locking, i.e.the oil pressure is only applied when changing the tool, not during the cutting process. The unitsoperate with a hydraulic pressure of 100 bar for size C4 and 80 bar for sizes C5-C8. | |
