Tool Turrets
Pragati Automation Pvt Ltd offers a range of Tool Turrets for CNC machine tools. Principle of working: electric motor drives the cam shaft through a system of gears; cam shaft indexes the follower shaft through a 'parallel index' drive mechanism; cam shaft is also geared to the 'drum cam' which controls clamping and release of the 3 piece coupling; one revolution of cam shaft completes one indexing cycle of 'declamping-indexing-clamping'; and absolute position encoder gives feedback of the turret position – proximity switch inspects the clamped position of the turret. Other types of tool turrets are: BTP turrets, servo turrets, vertical turrets and trainer turrets. Pragati Automation is a well known manufacturer of machine tool accessories particularly for CNC machines.
- Three piece face gear coupling allows tool disc to be indexed without lifting – it also ensures high repeat positioning accuracy and rigidity
- 'Parallel index' cam mechanism allows fast and smooth indexing of heavy tool discs – computer generated cam profiles ensure shock-free indexing action
- Totally enclosed, robust mechanism, with oil bath lubrication
- Electrical elements are conveniently located in a separate area, free from oil and coolant and bidirectional working can index in either direction to allow shortest indexing time
