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 Japan – for performance that is second to none.  An optional high-speed head with 6000 rpm spindle is also available – again, a first in its class.  Some lead, others follow.

 

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 done right.

Position-Trac scale has absolute encoder technology.  This allows MillPwr G2 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.

 

 

 

 

 

 

The quick-release knob allows the quill to be quickly release from the Z-axis drive mechanism so that the operator can use the quill/handle freely in manual DRO mode.  The Z-axis position readout is maintained to allow Z-position reading/display while in this manual DRO mode.

 

MillPwr G2 is manufactured in the United States at Acu-Rite’s ISO-9001 registered facility.  MillPwr G2 is backed by a comprehensive 1-year warranty.
