disc tool turret / axial / hydraulic / modular
MDT * series 20
MODULAR DRIVEN TOOL DEVICE FOR AXIAL SYSTEM DIN 5480 / 5482 COUPLING
The MDT device is a module that can be applied externally to the DM, SM or BSV-N standard turrets, taking place in the space between disc and turret housing normally used for the coolant group.
The MDT/20 series modular driven tool device, has been developed for supplying the best performances on CNC turning centers on which the servomotor turrets are usually fitted on.
The tool engagement is driven by a direct hydraulic cylinder.
The main features are:
– For improving the transmission efficency the motor is jointed directly on the main gear chain.
– Thank to the splined shaft coupling, MDT system allows heavy machining with a very accurte tool position control, i.e. rigid tapping.
– For prevent external contamination, a pressurizing air system can be supplied.
The MDT device is available in two different types:
For toolholders with DIN 5480 coupling (1) and zero detent system. In this type it is necessary that the servomotor (2) is provided with "orientation function" by CNC, in order
to stop the MDT device in “zero position”. The MDT cylinder (3) can be directly driven by the same electrovalve already employed for the turret.
In the MDT/ series 20 the zero setting is managed directly by the servomotor, that must be provided with “orientation function” by the CNC.
The motor driver enable must always be “ON”, keeping the zero position to allow the turret rotation. If servomotor with brake is used, the driver can be “disable” at the end of orientation, always keeping the brake on and the motor position control.
