日本动力工具公司和美国密特勒罗基·西斯特姆兹(M·S)公司共同开发出超精密“中心微进给气动夹头”,可保证每分钟一万转的超高速。第一批产品为3英寸规格的夹头,已经投放市场。能承受高速回转的夹头在结构上有许多难点,但由于该夹头采取了由内部的卡爪和传动装置组成的“斜楔机构”,改变了传统的夹头结构,致使卡爪对工件的夹紧力并无太大下降,夹头下降率控制在30%
Nippon Power Tools Co., Ltd. and Mithrasia West Mills Co., Ltd. jointly developed the ultra-precision “center micro-feed pneumatic chuck” that can guarantee a super high speed of 10,000 revolutions per minute. The first batch of products for the 3-inch chuck specifications, has been put on the market. The chuck capable of high-speed rotation has many structural difficulties, but because the chuck adopts a “wedge mechanism” composed of an internal claw and a transmission device, the traditional chuck structure is changed, causing the jaws to work on the workpiece Of the clamping force is not much decline, chuck reduction rate control at 30%
