Milltronics USA is introducing the VK4II CNC knee mill. Though it boasts more than two dozen improvements over the previous version, this mill retains the Milltronics Millslide Z axis. This machine offers a true three-axis control and can be run as a manual, teach or full CNC. The system provides greater rigidity and allows a programmable Z axis that can also be operated manually with a quill handle.

The X-, Y- and Z-axis travels measure 33" × 15" × 5.25", with 16.5" knee and a 5.9" quill (manual). The machine has a 54" × 12" table with a 1,500-lb. capacity.  The #40-taper, 3,900-rpm spindle is powered by a 7.5-hp back grear motor. The head tilts ±90 degrees, offering ±11.5" of ram travel swiveling ±90 degrees. Standard handwheels are directly coupled to the ballscrews and provide feedback to the operator. Options include flood coolant and drip pan, table guard, power knee and power draw bar.

Featuring the 8200-B CNC, the machine can be programmed with easy conversational G code or via a CAM system. The CNC is a PC-based control with advanced processing speeds, 2 GB disk storage, a 12" monitor and membrane keys. It has easy navigation function keys, solid model graphics, 3D pocket, DXF import, pockets, islands and tool tables. It also comes with help screens, mid-program restart and handwheel run. It features a variety of canned cycles such as drilling, boring, tapping and milling.
