Acu-Rite MillPwr CNC System -- FEATURES:
* Easy to use, menu prompted, conversational format
* 3D tactile-feel color keypad
* 10" flat panel LCD color display
* 3" floppy disk drive
* Remote stop/go switch
* Close loop feedback using precision linear glass scales
with absolute encoder -Position-Trac technology
* Precision hardened and ground ballscrews
* Direct DXF file input capability
* Alphanumeric engraving on line or arc
* Automatic cutter compensation for diameter and length,
with tool library
* Scale, skew, rotate, and mirror
* Position-Trac scale has absolute encoder technology. This
allows MillPwr control to find machine "home" position in
any axis by moving only up to 2" of travel. Once homed,
work piece datum is established and the control can repeat a
position even after being powered off. As an added benefit,
software limits can be set to safely keep machine travel
within machine travel limits without the need of additional
hardware limit switches and home switches.
AC-FREQUENCY DRIVE HEAD - A BETTER WAY:
AC-Freq drive models vary spindle rpm by changing the
frequency (Hz) of the power to the motor by electronic means
via a frequency inverter. No more sliding vari-disc with
plastic inserts means a more reliable milling head with less
maintenance issues. Runs quieter and smoother than standard
conventional mechanical sliding pulley drive systems. Three
phase power or single phase power. No need for a phase
converter - great for the shop or at home.
A HIGHLY RECOMMENDED OPTION:
A quick-change tooling system that allows quick tool change
while preserving the tool length preset will more than pay
for itself in a relatively short amount of time. The
standard R-8 spindle desing was simply not meant for cnc
uses. A good solution is the Mach-1 quick change tooling
package. Another way is to go with a NMTB-30 spindle and an
air-powered drawbar. This later method yields better
performance in terms of heavy cutting applications, since
a 30-taper tool holder is normally more rigid than a R-8
style quick change adaptor/holder. Thus Universal Kwik-
Switch system is an alternative to the NMTB-30 spindle where
heavy cutting applications is an issue. Here the standard R-
8 spindle is replaced with a custom Kwik-Switch spindle.
