——A precompensation method of thermal errors in CNC machine tools is presented.

但是，在机床上安装测温元件比较麻烦，引线也影响机床的正常工作。

The moulds and precision functional parts have applied to the machine tool made from the well-known and main manufactures in the world, such as Amada, Strippit, Murata, Trumpf, YangLi, JFY, Yawei and the like. They are widely used the field of sheet metal processing such as metal punching, sheet metal forming, etc..

模具及机床精密功能件等产品能够与世界主流机床配套，如Amada、Strippit、Murata、Trumpf、扬力、金方圆、亚威和捷迈等知名公司，并且广泛应用于金属冲裁、成形等钣金加工领域。

The purpose of the gross and the clamps design for assailing silk on the body crest face of the D3115 diesel engine machine is to be accord with the size request of 43,83, and 71 when processing the 14 threads.For satisfying the request of producing rate,and because of the number of the threads is numerous.we adopt the single work form combination machine to carry out processing of the threads.

D3115，柴油机机体顶面攻丝机床总体及夹具设计的目的是使在3115柴油机机体上加工14个螺纹孔M14-6H时，在14个螺纹孔间符合43、83、71尺寸要求，且为了满足生产率的要求，顶面的螺纹孔数量较多，特采用立式单工位形式的组合机床对多孔进行攻丝加工。

Calculates the coordinates of the spindle and drive shaft and checking the center distance, determined department spindle must use dislodges the gear.

根据柴油机齿轮室盖的结构特点、加工部位、尺寸精度、表面粗糙度及生产率等要求，确定该机床为单工位卧式组合机床；为确保加工精度，采用&一面两销&的定位方案；为实现无级调速，安全可靠，选择液压滑台；根据零件的大小及被加工孔的位置确定主轴箱的轮廓尺寸；由加工工艺选择滚珠轴承主轴，通过计算扭矩确定主轴和传动轴的直径；齿轮的模数是通过类比法确定；齿轮齿数和中间传动轴的位置是由&计算、作图和多次试凑&相结合的办法确定；计算主轴、传动轴的坐标并进行中心距验算，确定部分轴上需采用变位齿轮；轴上的齿轮套、键等零件按轴号选取相应的标准件。

Meanwhile, she is equipped with the most advanced production and inspection machines: one Mitsubishi 4-axis drilling-milling machine center, five 3-axis drilling-milling machine centers, 50 CNC lathers, 14 general lathers, Three-Dimensional Inspection Machine, Angle Inspection Machine, Salt Spray Machine, Surface Roughness Inspection Machine etc.
