AC-Freq 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.
Did you know?
In IMTS-1992, Kent show case the first AC-Freq drive head on
a knee mill to the general machine tool public. This caught
our competitors by surprise and generated a lot of interest -
well actually more from our competitors than shop users at
the time. We are the first to put in a digital rpm display
for easy and precise spindle speed adjustment. We are the
first to put in an analog spindle load meter. Today, we
lead this field with the highest performance AC-Freq drive
head on the market with 0-4500 rpm in under 3 seconds. We
use the latest generation of flux-vector inverter drives
made in the USA - for performance that is second to none.
An optional high-speed head with 6000 rpm spindle is also
available - again, a first its class. Some lead, others
We don't use 3rd party installer:
It is surprising to us that most of our competitors in this
field actually do not install the cnc package themselves -
they usually hire a 3rd party person to do the installation.
While this saves overall cost, we believe it does not
provide the best overall quality and reliability for our
customers. A 3rd party installer gets paid per job, whether
it takes 1 day or 1 week to finish the job. His main goal
is to get it done as quickly as possible, not necessary do
the best job possible. In contrast, Kent cnc mills are
installed by full-time Kent employees - his job is to do it
right. Not the fastest way every time, always the right way
every time. Take comfort in knowing that your cnc mill was
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 design 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. The 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.

ACU-RITE MILLPWR CNC SYTEM - 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.
MillPwr is manufactured in the United States at Acu-Rite's
ISO-9001 registered facility. MillPwr is backed by a
comprehensive 1-year warranty.
