Milltronics USA’s VM8434XP is a #50 taper VMC designed for applications that need extra cutting power, like the rest of the XP Series VMCs. The VM8434XP is built with linear cross roller guides for rigidity, direct-coupled ballscrews for faster response and a dual-wound spindle motor for faster acceleration/deceleration and more torque, the company says. With 35 hp for maximum metal removal, the VM8434XP also includes a heavy-duty belt driven, 8,000 rpm spindle that generates 365 foot-pounds of torque with a maximum cutting feed rate of 500 ipm.

Features such as a coolant ring and washdown system, lift-up chip conveyor, and height adjustment on the control are standard on XP Series machines. The VM8434XP is now the largest XP Series machine with 84" x 34" x 30" travels and a 86" x 34" table.

All XP Series machines are equipped with the 9000 Series control that includes 120-GB disk storage, 4-GB memory, improved graphic performance, mid-travel tactile keys and a 15" LCD touchscreen. The 9000 control allows operators to run parts programmed conversationally or by toolpaths generated by a CAM system.

The 9000 Series control also supports the optional ChipBoss feature that uses algorithms to calculate toolpaths and control maximum allowable cutter engagement. ChipBoss lets you use the whole length of a tool rather than just the tip, which means you can cut profiles at full depth rather than taking multiple depth passes. This new optional software works by automatically controlling the tool’s chip load, keeping it constant and creating the optimal chip, which results in faster cycle times, better tool life, and more accurate parts. Cycle times (depending on geometry) can be reduced by as much as 50% percent with up to three to five times better tool life, the company says.
