機床釆用鑄造整體箱形寬大底座，床身、主軸箱安裝于底座上部，箱型滑鞍在床身上運動，形成Z軸運動，X軸滑板在滑鞍上運動，形成X軸運動。床身、主軸箱,滑鞍
及X軸滑板均釆用優(yōu)質(zhì)鑄鐵。
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向運動導軌副釆用超重負荷直線滾動導軌副，使用高強度螺釘安裝于床身，X軸滑板及滑鞍上。中置滾珠絲杠，兩端固定并經(jīng)預(yù)拉伸。滾珠絲杠兩端支承為特制軸
承組件單元。絲杠軸端與進給伺服電機軸釆用彈性聯(lián)軸器聯(lián)接。可實現(xiàn)高精度、高剛性、高速度運動。
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.
機床主軸為套筒式單元主軸，套筒材料為體質(zhì)合金剛，軸承安裝孔精度磨削而成。主軸材料為氮化合金剛。合理的軸承組配方式，使主軸單具有很高的回轉(zhuǎn)精度及剛
度，主傳動帶輪一般釆用多楔帶輪，實現(xiàn)高效平穩(wěn)地運動。機床主軸頭部型式為A2-5，可以安裝中空、中實夾盤及各類不同形式彈性專用卡具，機床主軸也可選裝C
軸功能，如再安裝部分動力刀座，即可完成鉆銑功能。零件卡緊方式可為液壓及氣動。
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.
機床標準換刀方式為直線排刀式，也可換裝六至八位刀塔，或排刀與刀塔混合安裝，使刀位數(shù)更多、更豐富。
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.
機床外觀緊湊，操作方便宜人，維護簡單。
The machine tool has the advantages that the appearance is compact, the operation is convenient, and the maintenance is simple.
