medical customer cuts saws used in knee replacement surgeries, notes Jeff Hahn, Mitsubishi Laser national product manager. The hybrid laser offers better accuracy and a simpler machine tool design, with the stability inherent in the system’s cast frame made from Di- anite, which Hahn says is Mitsubishi’s version of Meehanite. “Generally, the hybrid has the best accuracy,” Hahn notes. “Bone saws are generally a very intricate piece, and it’s nothing that you’re going to go fast at. But with the 2-D hybrid 2-kW laser, in this applica- tion, it’s cutting thin stainless at about 0.0060" (0.152-mm) thicknesses, and when you’re using nitrogen-assist, it will give you a low HAZ.”
The HV II machine, which Mitsubi- shi demonstrated at Fabtech 2011, features the company’s latest M700 series control with a 15" (380-mm) color touchscreen display. The HVII series is available with either a 2, 3, or 4-kW laser resonator. Travel in the Z axis is two times faster than previous models, according to the company, resulting in cutting part-to-part transition times in
half. Larger stroke in the Z axis allows preformed parts to be loaded in and out. The machine also offers an attached tool storage center, a fine-pierce option, and a diminished clamp zone for increasing parts production and quality. ME
