【正文】 發(fā)展儼然已超越其為數(shù)控加工中心配套的角色，在其特有的技術(shù)領(lǐng)域中發(fā)展出符合機(jī)床高精度、高效率、高可靠度及多任務(wù)復(fù)合等概念的獨特產(chǎn)品。 斗笠式刀庫 一般只能存 16~24 把刀具，斗笠式刀庫在換刀時整個刀庫向主軸移動。當(dāng)要換的刀具對正主軸正下方時主軸下移，使刀具進(jìn)入主軸錐孔內(nèi)，夾緊刀具后，刀庫退回原來的位置。s development. Rain hat type knife library normally only save 16 to 24 knife sword rain hat type, change cutters in the library in the sword to the spindle mobile library. Rain hat type knife library normally only save 16 to 24 knife sword rain hat type, change cutters in the library in the sword to the spindle mobile when spindle library on the library card slot cutter into the knife, spindle, when moving upwards from cutter knife library rotation. When to change tool to align the spindle, when spindle moves directly into the spindle cone hole cutter, clamping tool, return the original position knife library.
