KAIWA's stainless steel vise for MC

KAIWA's stainless steel vise for MC

Kaiwa (Uenohara City, Yamanashi Prefecture) has launched a new stainless steel 5-direction centering vise for machining centers (MCs) that holds workpieces from four directions on both sides of the XY axis. It is suitable for ultra-precision machining of workpieces up to 50 mm in length and 60 mm in width using a 5-axis MC. The mouthpiece is interchangeable to suit the machining purpose. Even rectangular or round-shaped workpieces can be held securely. Both Y-axis and X-axis workpieces are fixed in the center position by separate screw tightening operations. "Mr. Yamazoe says, "The unique structure of the machine, which has no internal bearing mechanism, prevents rattling even after long-term use. The clamping jig of the optional vise has elasticity to soften the impact when the machining head and other parts collide. The vise is assembled from multiple parts. The external size is 120mm (length) x 110mm (width) x 90mm (height). Photo taken on November 1, 2019, credit: Nikkan Kogyo Shimbun / Kyodo News Images
