Haas Technical Center offers Mould Maker, VM-6. The new large-frame VM-6 is a high-performance VMC that provides the accuracy, rigidity and thermal stability required for high-precision work. It has 64" x 32" x 30" travels, a 12,000-rpm spindle driven by a 30-hp vector dual-drive system, a 24-pocket side-mount tool changer and a high-speed control with full look-ahead capability. The VM-6 features massive cast-iron construction, with extensive internal ribbing on the castings to increase rigidity and damp vibrations. High-precision linear guides on all axes further increase rigidity, while offering low-friction and long-term reliability. High-speed brushless servos, combined with fine-pitch ballscrews and high-resolution encoders, ensure precise positioning and extreme repeatability. The VM-6"s 40-taper spindle uses a unique inline direct-drive system that couples the motor directly to the spindle to reduce heat, vibration and noise. This results in smooth, quiet operation and extreme thermal stability. On-the-fly wye-delta switching provides plenty of low-end torque, as well as high rpm for high-speed machining. To further ensure thermal stability, coolant is circulated through the VM-6"s head casting to remove heat generated by the spindle. To prevent radiated heat from affecting the casting, the headstock is insulated and cool air is circulated through the entire assembly. The VM-6 comes standard with a 24-pocket side-mount tool changer that swaps tools in 2.8 seconds.
