1) Vertical machining center

　　立式加工是指用于立式加工的主轴。其结构形式是固定的列,工作台是矩形的,没有分度功能,适合处理盘,封面,董事会的部分,一般有两个直线运动坐标轴,并可以安装一个沿水平轴转盘工作表,以螺旋线的一部分过程。

　　Vertical machining center refers to the spindle used for vertical machining center. Its structure is a fixed column, the table is rectangular, no indexing function, suitable for processing disk, cover, board of directors. Generally, it has two straight-line motion coordinate axes, and can install a rotary table along the horizontal axis to spiral a part of the process.

　　立式加工安装方便，操作方便，加工观察方便，程序调试方便，应用广泛。但由于立柱高度和换刀装置的限制，过高的零件无法加工。模具型腔或凹面加工时，切屑不易排出，刀具损坏严重，加工表面受损，影响加工的顺利进行。

　　The vertical machining center is easy to install, operate, observe, debug and apply. However, due to the limitation of column height and tool changing device, high parts can not be processed. When the mold cavity or concave is processed, the chip is not easy to be discharged, the cutter is damaged seriously, and the machining surface is damaged, which affects the smooth processing.

　　2)卧式加工

　　2) Horizontal machining center

　　卧式加工是指主轴处于水平状态的加工。卧式加工通常是自动索引转盘,一般有三到五坐标运动,常见的是三个线性运动坐标和坐标旋转运动,工件卡,除了安装完成后,剩下的四个表面的顶面处理,它更适合于增加身体部位。与立式加工相比，卧式加工具有易去屑、加工优点，但结构复杂。更高。

　　Horizontal machining center refers to the machining center with the spindle in horizontal state. The horizontal machining center is usually an automatic index turntable, which generally has three to five coordinate movements. The common ones are three linear movement coordinates and coordinate rotation movements. The workpiece card, except for the top surface treatment of the remaining four surfaces after the installation, is most suitable for adding body parts. Compared with the vertical machining center, the horizontal machining center has the advantages of easy chip removal and machining, but its structure is complex. The price is higher.

　　3)龙门加工

　　3) Gantry machining center

　　龙门加工的外形与数控龙门铣床相似。龙门加工主轴主要是垂直设置,除了自动改变设备的工具,但也与主轴头的更换配件,数控设备功能也相对完整,可以多用途的机器,特别适用于加工大型工件和复杂形状的工件

　　The shape of gantry machining center is similar to that of CNC gantry milling machine. The spindle of gantry machining center is mainly set vertically. In addition to automatically changing the tools of the equipment, it also changes the accessories with the spindle head. The function of the numerical control equipment is relatively complete. It can be used for multi-purpose machines, especially for processing large workpieces and workpieces with complex shapes

　　4)五轴加工

　　4) Five axis machining center

　　五轴加工具有立式加工和卧式加工的功能。五轴加工，工件完成后可以安装在其他五轴加工的安装面。常用的五轴加工有两种形式:一是主轴可旋转900度。对工件进行垂直和水平加工;另一种是主轴不改变方向，而是由工作台带动工件转动900度。完成工件五面加工。

　　Five axis machining center has the functions of vertical machining center and horizontal machining center. Five axis machining center, the workpiece can be installed on other five axis machining mounting surface after completion. The commonly used five axis machining center has two forms: one is that the spindle can rotate 900 degrees. The other is that the spindle does not change the direction, but the worktable drives the workpiece to rotate 900 degrees. Finish five side machining of workpiece.

　　5)多轴加工

　　5) Multi axis machining center

　　多轴加工改变了传统机床的结构，通过连杆的运动实现多自由度主轴的运动，完成了对复杂工件表面的加工。

　　The multi axis machining center changes the structure of traditional machine tool, realizes the movement of multi DOF spindle through the movement of connecting rod, and completes the machining of complex workpiece surface.
