性能特点  Performance Features

◆ 曲轴内部油路循环设计，抑制曲轴热变形。
◆ 自有特殊技术控制游隙。
◆ 钢珠零间隙导向，垂直精度长期保障。
◆ 可调节垫圈，以很小的代价恢复设备精度。
◆ 机身拉杆和滑座导向一体化，结构紧凑合理，滑座由滚珠作为导向，精度高。
◆ 液压锁紧拉杆，稳定性可以长期保持。
◆ 两侧分离式离合制动器使得曲轴受力平衡，减少轴承磨损。
◆ 床身刚性挠度值的严格控制1/15000；床身材质严格把控QT500-7。

◆ The internal oil circulation design of the crankshaft suppresses thermal deformation of the crankshaft.
◆ Own special technology to control the clearance.
◆ Steel ball zero gap guidance ensures long-term vertical accuracy.
◆ Adjustable washers to restore equipment accuracy with minimal cost.
◆ The body pull rod and slide guide are integrated,with a compact and reasonable structure.The slide seat is guided by ball bearings, with high accuracy.
◆ Hydraulic locking rod,stability can be maintained for a long time.
◆ The separated clutch brake on both sides balances the force on the crankshaft and reduces bearing wear.
◆ Strictly control the rigid deflection value of the bed by 1/15000;The bed material is strictly controlled by QT500-7.
