KENT USA®’s industry-standard CNC knee mills come factory-installed with the unassailable
ACU-RITE MILLPWR G2 system. Designed with advanced safety and superior operational
features, our knee milling machines make for an ideal choice at production and training
facilities alike.
These features enhance functional efficiency and precision while also significantly improving
and ensuring safety for the user—providing a secure environment for operators of all skill
levels—at machining facilities large and small.

The ACU-RITE MILLPWR G2 system offers several of these safety and operational features
designed to promote successful machining and ease-of-use:

1. E-Stop Functionality:
   Emergency stops (E-stops) are located on both the head control and the ACU-
   RITE G2 Control. Whether the operator is near the control or on the other side of
   the table, either E-stop will completely shut down the machine.
2. Safety Microswitch for Switching Gears:
   The spindle rotates according to the forward/reverse switch settings while in high
   gear. Traditionally, in low gear, the direction reverses—requiring manual
   adjustment. KENT USA® CNC Knee Mills are equipped with a microswitch that
   automatically toggles the motor to reverse when shifted to low gear, ensuring
   correct rotation in both high and low gears. This feature prevents potential
   damage to the tool, machine, and operator.
3. RPM Setting on Acu-Rite G2 Control:
   Operators can set the RPM directly on the CNC control, allowing them to preset
   spindle speeds for corresponding tools. When tools are changed in the correct
   sequence, the system automatically resets to the pre-set RPM for each specific
   tool.
4. Digital Inverter Drive Head:
   The digital inverter drive head has fewer moving internal components compared
   to standard variable speed heads, which traditionally use cone-shaped pulleys to
   vary speed. Instead of relying on mechanical adjustments, the digital drive head
   uses frequency drive to change speeds, providing a more efficient and precise
   control.
5. Spindle Load Meter:
   The DRO on the head control displays the spindle load, helping to detect when
   cutters are starting to wear out. Traditionally, this would be detected manually by
   listening or feeling for additional required pressure. The spindle load meter offers
   a proactive visual reference, allowing operators to stop the machine immediately
   upon detecting an unusual load, change the tool, and resume operations.

All told, these ACU-RITE MillPWR G2 system features ensure safety and peace-of-mind for the
user, allowing him or her to pursue enhanced precision and efficiency while operating the
machine. Whether the user is a first-year machine tool technology student or a seasoned
technician in charge of large production runs, ACU-RITE’s MILLPWRG2 system is a robust
solution for modern machining needs.
