* A stand alone refrigerated spindle coolant chiller and temperature stabilizer unit
 pumps temperature controlled fluid completely around the main drive motor
 stator. This precise system can hold the spindle motor/spindle assembly to +/- 1
 degree C of the work shop's ambient temperature during the full range of cutting
 speeds. Work piece accuracy is tremendously enhanced because of spindle
 thermal stability along with extending the life of the entire main motor/spindle
 bearing assembly.

* Fail Safe sensors and gauges strategically positioned through this coolant system
 feedback real time information to the CNC controller which constantly monitors all
 functions. A fault in any area shuts down the machine, displays the fault area on
 the OPT monitor for the operator and records the warnings in memory.
 
 

* The disc magazine type Automatic Tool Changer (ATC) is utilized for its simple
 but highly reliable design. 12 sets of BT40 tools can be stored in the ATC with a
 maximum diameter of 80 mm (approx. 3") and length of 3OO mm (approx. 12")

* A remote hand-held control unit is provided for auxiliary set-up, loading and
 unloading of the ATC magazine.
 
 

* Formed as part of the base casting of the AV-128 frame are dual coolant and chip
 troughs. Flooded by powerful coolant spray lets at the ends of the troughs, chips
 and coolant are flushed forward and directed into the front roll-out chip drawers.
 Chips are screened and separated from the coolant which is recirculated.
A Chip Conveyor System is available as an option.
 
 

* Laser certified Class-3 grade super precision ball screws are used on all three
 axes. Oversized in diameter for extra rigidity, they are set in pre-loaded double
 end bearing housings laser positioned for axial integrity alignment. Ballscrews
 are then critically pretension to provide the maximum possible rigidity and
 positioning precision demanded by high speed fast servo motor ramp
 acceleratlon/deceleration rotational forces.
 

* Sustaining this precision during demanding production hours of high speed
 motion and positioning requires eliminating the effects of ball-screw thermal
 growth from heat build-up. Otherwise, problems with positioning and
 repeatability will develop. A completely separate free standing oil refrigerated
 chiller system feeds temperature controlled oil flowing through the center of each
 ball-screw. This draws heat build-up from the periphery of the ball-screw into the
 interior coolant cavity and evacuates the heat by transferring it to the flowing oil
 coolant . Coolant temperature is precisely maintained by monitors in the chiller
* Specially designed rotary couplings at  either end of the ball screw provide a
 leak free connection for the ball-screw  coolant oil flow.
