Long thought of by many as today’s easiest-to-operate CNC for vertical knee mills, HEIDENHAIN’s ACU-RITE-brand MILLPWRG2 control is now also available for bed mills with AC motors.
Combining the latest technology with the finest qualities in traditional machining, this new bed mill control package offers many useful machining features including full 3D contouring capabilities. It is available as a complete retrofit package for 2- or 3-axis machines or already installed on many new machines.
With its conversational 2-1/2 axis shop floor programming and built-in calculators, the MILLPWRG2 continues to provide convenience to machinists by eliminating time-consuming calculations and the need to learn complicated programs. In addition, it has the ability to run G-code files from CAD/CAM programs, which gives users the capability of the full 3D contouring. Consequently, it maximizes productivity for machinists of all levels, from the less experienced operator to the most seasoned veteran.
The MILLPWRG2 control features a sturdy operator console that includes a 12.1-inch flat panel color LCD display, a color-coded well-organized keypad, and USB and Ethernet as all standard equipment. This new offering is specifically designed for bed mill applications that are CNC ready (meaning the machine has the ball screws and motor mounts already installed), and includes powerful AC motors and drives, a remote handwheel as standard, and spindle control override. It also allows machine function capabilities to be integrated, (when the machine is equipped for spindle drive inverter, coolant pumps, indexers, oilers, misters, etc.).

- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- flat ( screw flat)
flat ( screw flat)
Flat surface machined into the shank of a cutting tool for enhanced holding of the tool.
- milling machine ( mill)
milling machine ( mill)
Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.
