Ta-Center
Numerical control boring and facing heads with automatic balancing on machining centers with automatic tool change and special machines.
General features
TA-CENTER boring and facing heads are made to be used on machines with automatic tool change, therefore on essentially all machining centers. A U-Drive unit commands the feed control of the tool slide and the tool placement even during rotation. This unit is managed directly by an axis called “U” by the machining center NC.
Organized in this way, the machining center is the solution to a series of different processes like inner and outer turning operations, grooves, conical and variable boring, concave and convex corner rounding, cylindrical and conical threading, phonographic grooves and spherical machining.
Any application on machines that do not permit the connection to an axis of the NC, may be made by managing the motor of the U-DRIVE with a practical, simple, and economical U-CONTROL positioner with wireless REMOTE-CONTROL. The positioner can be connected to the M functions of the machine to receive start signals of the various operations programmed on the REMOTE-CONTROL. Spherical machining is not possible with machines equipped with the U-CONTROL WIRELESS KIT.
U-Drive
The U-DRIVE drive unit must be mounted on the machining center in a proper position next to the spindle so as to ensure the mechanical connection of the drive with the TA-CENTER head. The main components of the U-DRIVE are:
– base element
– servomotor
– mechanical unit for automatic connection of the TA-CENTER to the drive
– the unit comes with air inlet connection for cleaning the drive.
The U-DRIVE drive unit can be configured in different ways depending on the application on the machining center for example:
– horizontal
– horizontal at 90°
– vertical.
And it can be easily connected to the NC.
U-DRIVE application
D’ANDREA has developed a standard U-DRIVE drive unit (horizontal and at 90°), on which different types of motors can be fitted.
The U-DRIVE can be easily positioned on the machine with a support plate adaptor to the machine connected and fastened to the holes on the front of the spindle.
Other special configurations can be provided upon request.
Command Unit
TA-CENTER can be applied on machining centers and can be managed directly from an axis called “U” of the numerical control.
Any application on machines that do not permit the connection to an axis of the NC, may be made by managing the motor of the drive unit with a practical, simple, and economical U-CONTROL positioner with wireless REMOTE-CONTROL.
The positioner can be connected to the M functions of the machine to receive start signals of the various operations programmed on the REMOTE-CONTROL.
Coolant supply
Coolant exits from the two adjustable nozzles in the TA-CENTER located next to the slide after crossing the taper and the rotating body of the head. This noteworthy advantage ensures longer duration of the insert, quicker cutting speed and achievement of good surface finishes.
The centralized supply of coolant does not harm the TA-CENTER, its internal labyrinths are protected by O-rings. It is advisable to not exceed a pressure of 40 BAR.
Balancing
Sui portautensili D’andrea possono essere montati utensili standard per eseguire lavorazioni semplici e multiple di tornitura interna ed esterna, alesature coniche anche variabili, raggiature concave e convesse, canalini, filettature cilindriche e coniche, sfacciature, spirali fonografiche ecc.
Tool applications
Standard tools can be mounted on D’ANDREA toolholders to perform simple and multiple machining of internal and external turning operations, tapered and variable boring, concave and convex corner rounding, grooves, cylindrical and conical threading, facing, phonographic grooves, etc.
