The latest generation of the Milltronics USA, Inc. VK Series is its VK4II CNC knee mill. With more than two dozen improvements over the previous version, the VK4II retains the Milltronics MillSlide Z-axis. Popular in tool rooms, prototype, R&D and job shops, VK Series machines offer a true three-axis control and can be run as manual, teach or full CNC. The company says its MillSlide provides greater rigidity and allows a programmable Z-axis that can also be operated manually with a quill handle.

Travels are 3 (X) by 15” (Y) by 5.25” MillSlide (Z) with 16.5” (knee) and 5.9” quill (manual). The machine has a 54” by 12” table with 1,500 lbs. capacity. Powered by a 7.5-hp back-geared motor, the VK4II is a No. 40 taper with a two-speed 3,900-rpm spindle. The head tilts ± 90°, offers 11.5” of ram travel, which also swivels ±90°. Options include flood coolant and drip pan, table guard, power knee and power draw bar.

Featuring the Milltronics Series 8200-B CNC, the VK4II can be programmed with easy conversational, G-code or a CAM system. The 8200B is a PC-based control with advanced processing speeds, easy navigation function keys, solid model graphics, 3D pocket, DXF import, pockets & islands, tool tables, help screens, mid-program restart, handwheel run, scaling, mirror image, rotate and a variety of canned cycles such as drilling, boring, tapping, milling and more.

According Milltronics, the VK4II is a machine that fits its customers’ requests.
