机床釆用铸造整体箱形宽大底座，床身、主轴箱安装于底座上部，箱型滑鞍在床身上运动，形成Z轴运动，X轴滑板在滑鞍上运动，形成X轴运动。床身、主轴箱,滑鞍

及X轴滑板均釆用优质铸铁。

The machine tool adopts a wide and large monoblock casting base seat, the body and the spindle box are mounted at the upper part of the base

seat, the box-type saddle is moving on the body to form the Z-axis movement, and the X-axis slide plate is moving on the saddle to form the X-

axis movement. The body, the spindle box, the saddle and the X-axis slide plate all adopt the cast iron.

X,Z向运动导轨副釆用超重负荷直线滚动导轨副，使用高强度螺钉安装于床身，X轴滑板及滑鞍上。中置滚珠丝杠，两端固定并经预拉伸。滚珠丝杠两端支承为特制轴

承组件单元。丝杠轴端与进给伺服电机轴釆用弹性联轴器联接。可实现高精度、高刚性、高速度运动。

X and Z direction movable guide pairs adopt overweight load Linear rolling guide pairs, which are mounted on the body, the X-axis slide plate

and the saddle by using high strength bolts. A ball screw is arranged in the middle, with both ends fixed and pre-stretching treated. The

supports for both ends of the ball screw are specially made bearing assembly unit. The axle heads of the ball screw are connected with the servo

motor shaft through a resilient coupling. High accuracy, high rigidity and high speed movement can be realized.

机床主轴为套筒式单元主轴，套筒材料为体质合金刚，轴承安装孔精度磨削而成。主轴材料为氮化合金刚。合理的轴承组配方式，使主轴单具有很高的回转精度及刚

度，主传动带轮一般釆用多楔带轮，实现高效平稳地运动。机床主轴头部型式为A2-5，可以安装中空、中实夹盘及各类不同形式弹性专用卡具，机床主轴也可选装C

轴功能，如再安装部分动力刀座，即可完成钻铣功能。零件卡紧方式可为液压及气动。

The spindle of the machine tool is a sleeve type unit spindle, the material of the sleeve is constitutional alloy steel, and the bearing

mounting hole is made through precise grinding. The material of the spindle is nitride alloy steel. Rational assembling mode for bearing makes

the spindle has very high swing precision and rigidity, the main drive pulley generally adopts multi-wedge pulley, and realizes high efficient

and smooth movement. The model of the spindle nose of the machine tool is A2-2, hollow solid chuck and various types of special elastic chucking

appliances, the spindle can mount an optional C-axis function, if a partially dynamic tool holder is mounted, the milling and drilling can be

finished. The clamping method for parts can be hydraulic or pneumatic.

机床标准换刀方式为直线排刀式，也可换装六至八位刀塔，或排刀与刀塔混合安装，使刀位数更多、更丰富。

The standard tool changing method of the machine tool is linear tool-arranging type, 6-8 tool turrets also can be mounted, or the tool-arranging

type and the tool turret are mounted together, so that the number of the tool position is large and abundant.

机床外观紧凑，操作方便宜人，维护简单。

The machine tool has the advantages that the appearance is compact, the operation is convenient, and the maintenance is simple.
