<p>現(xiàn)在鉆攻中心普遍都是BT30規(guī)格的直聯(lián)式主軸，同動式刀庫一般是用在高速加工中心BT40規(guī)格的直聯(lián)式主軸，夾臂式刀庫相對比較合適BT30規(guī)格的主軸。從外形上看，夾臂式刀庫是前置在主軸箱前面的，同動式刀庫與普通的圓盤式刀庫沒大區(qū)別。夾臂式刀庫裝刀數(shù)量常見16和21位，同動式刀庫裝刀數(shù)… <a

<p>同動式刀庫雖然與普通的圓盤式刀庫的外觀并無大差異，但同動式刀庫運用的前提是主軸必須是直結式主軸，而因此產生的取消環(huán)形打刀缸而采用機械凸輪機構實現(xiàn)杠桿式打刀，從而消除了由于直結式主軸的多項弊端。同動式刀庫更適合BT40的主軸，而且裝刀數(shù)量一般是20/24把要比夾臂式16把多。… <a href="/bethel/wd/show_445.html"

由于現(xiàn)時代鉆攻中心和高速加工中心等一系列高速產品都選用了直結式主軸，但這樣一來主軸不但承愛了兩端的軸承定位，也同時受主電機直聯(lián)而產生了三點過定位問題，為了解決過定位的問題，原來主軸所依循的長徑比規(guī)律也因此必須做出改變，主軸必須盡… <a href="/bethel/wd/show_396.html" target="_blank">[了解更多]</a></p>
