<p>同动式刀库虽然与普通的圆盘式刀库的外观并无大差异，但同动式刀库运用的前提是主轴必须是直结式主轴，而因此产生的取消环形打刀缸而采用机械凸轮机构实现杠杆式打刀，从而消除了由于直结式主轴的多项弊端。同动式刀库更适合BT40的主轴，而且装刀数量一般是20/24把要比夹臂式16把多。… <a href="/bethel/wd/show_445.html"

由于现时代钻攻中心和高速加工中心等一系列高速产品都选用了直结式主轴，但这样一来主轴不但承爱了两端的轴承定位，也同时受主电机直联而产生了三点过定位问题，为了解决过定位的问题，原来主轴所依循的长径比规律也因此必须做出改变，主轴必须尽… <a href="/bethel/wd/show_396.html" target="_blank">[了解更多]</a></p> </div> <!-- 内容列表结束
