href='http://www.simonredekop.com/news/168.html'>http://www.simonredekop.com/news/168.html</a></span>  更新时间?019-09-10</div> <div class="mm"><p> <a target="_blank" href="http://www.simonredekop.com/news/168.html">天津数控车床加工的操作技?/a> </p> <p> 一、编程技?</p> <div style="text-align:center;"> <img src="/uploads/image/20190910/20190910092228_7402.jpg" alt="" /> </div> 1. 零件的加工顺序:<br /> 先钻孔后平端(这是防止钻孔时缩料);<br /> 先粗车,再精车(这是为了保证零件精度);<br /> 先加工公差大的最后加工公差小的(这是保证小公差尺寸表面不被划伤及防止零件变形)?br /> 2. 根据材料硬度选择合理的转速、进给量及切深:<br /> 1)碳钢材料选择高转速,高进给量,大切深。如?Gr11,选择S1600、F0.2、切?2mm?br /> 2)硬质合金选择低转速、低进给量、小切深。如:GH4033,选择S800、F0.08?切深0.5mm?br /> 3)钛合金选择低转速、高进给量、小切深。如:Ti6,选择S400、F0.2、切?.3mm。以加工某零件为例:材料为K414,此材料为特硬材料,经过多次试验,最终选择为S360、F0.1、切?.2,才加工出合格零件?br /> 二、对刀技?br /> 对刀分为对刀仪对刀及直接对刀。我厂大部分车床无对刀仪,为直接对刀,以下所说对刀技巧为直接对刀?br /> 先选择零件右端面中心为对刀点,并设为零点,机床回原点后,每一把需要用到的刀具都以零件右端面中心为零点对刀;刀具接触到右端面输入Z0点击测量,刀具的刀补值里面就会自动记录下测量的数值,这表示Z轴对刀对好了,X对刀为试切对刀,用刀具车零件外圆少些,测量被车外圆数值(如x?0mm)输入x20,点击测量,刀补值会自动记录下测量的数值,这时x轴也对好了;这种对刀方法,就算机床断电,来电重启后仍然不会改变对刀值,可适用于大批量长时间生产同一零件,其间关闭车床也不需要重新对刀?br /> 三、调试技?br /> <p> 零件在编完程序,对好刀后需要进行试切调试,为了防止程序上出现错误和对刀的失误,造成撞机事故,我们应该先进行空行程模拟加工,在机床的座标系里面对刀具向右整体平移零件总长?—?倍;然后开始模拟加工,模拟加工完成以后确认程序及对刀无误,再开始对零件进行加工,首件零件加工完成后,先自检,确认合格,再找专职检验检查,专职检验确认合格后这才表示调试结束?</p> <p>
