Numerical Control Machine Returning Reference point by??rule and line,Affect Stability Of Machine,And that,Affect Precision of Machine.

数控机床回参考点的准确性，不但影响机床的稳定性，更重要的还影响加工精度及加工尺寸的稳定性。

Milling groove machine is used in processing weaving trade in " pin plate " use privately cut machine tool, belong to the modular machine tool, this machine tool have 4 works position and 8 milling heads, can at the same time process 8 workpieces, have higher processing efficiency and processing precision, and can at the same time still realize needle groove and circular arc groove same work position, it surmounted the shortcoming of that machining process complex, processing efficiency low and process precision do not be in height of the processing of pin plate beforetime, so it have better application prospect.

铣槽机是用于加工纺织业中&针板&的专用切削机床，属于典型的组合机床，该机床具有四工位、八铣头，能同时加工八个工件，具有较高的加工效率和加工精度，同时还能实现针槽与圆弧口槽同工位一次完成，克服了以前针板加工中加工工序复杂、加工效率低、加工精度不高的缺点，有较好的应用前景。

During the process, the whole position errors on the plane were measured by using the equipment that can only measure a small field. The positional errors on the entire plane table of CNC machine tools were obtained by measuring the error of the basic postion near the original point.

该方法以距离机床坐标原点较近的点（该点的误差直接通过测量仪器获得）为基点，从而获得离机床坐标原点较远位置点的误差，依此类推，最终获得整个机床平面上位置点的误差信息。

Hydraulic planer the advantages of a smooth drive, the introduction of hydraulic drive, ram a uniform velocity,and can achieve variable speed; load capacity than the general mechanical transmission large Shaper;ram can be in any position to immediately stop or start;Stage movement to apply the hydraulic drive,feed rate can be in a certain range without adjustments; Machine done by hydraulic valve protection, are not too easy to damage the machine parts;Part of the oil is not easy to work wear, so long machine life;manipulating simple and convenient.

液压刨床的优点是传动平稳，由于采用液压传动，滑枕的运动速度均匀，且可实现无级调速；负荷能力比一般机械传动的牛头刨床大；滑枕可以在任何位置上立刻停止或起动；工作台的进给运动也采用液压传动，进给量可以在一定范围内无级调整；机床由液压安全阀做保护，过载时不容易损坏机床的零部件；零件在油里工作不易磨损，因而机床寿命长；操纵简单，使用方便。
