重型数控立式铣车床的横梁升降装置

Cross rail lifting device of CNC heavy duty milling-turning lathe

通过研制重型数控立式铣车床的横梁升降W轴进给装置,实现了滑枕定悬伸等刚度切削,显著提高了横梁升降的速度和精度;通过取消60t重的横梁平衡重锤装置,大大降低了机床的重量和成本。

Through the preparation of heavy CNC vertical milling-turning lathe cross rail lifting W shaft feeding device,realizes the RAM will overhang and stiffness cutting,significantly improves the beam lifting speed and accuracy;greatly reduces the weight and cost of the machine tool by removing 60 tons of cross rail balance weight device.
