重型立车如何更好的完成其加工工艺？

在重型立车加工中，操作者应该注意什么，才能更好的进行重型立车加工？虽然和普通车床的加工差不多，但还是有一些区别需要我们特别注意，因为重型立车是一次装夹，所有车削加工都是连续自动完成的。重型立车如何更好的完成其加工工艺？下面我们大家一起来简单了解一下。

对于重型立车，经济有效的加工方法必须是切削条件的合理选择，切削速度、进给速度和切削深度会直接造成刀具的损坏。如果切削速度增加，刀尖的温度会升高，导致机械、化学和热磨损，一般切削速度提高20%，刀具寿命会减少1/2。

用户应根据加工材料、硬度、切削状态、材料类型、进给速度和切削深度等选择合适的切削速度，规律稳定是理想的状态，粗车时，选择强度高、耐用度好的刀具，满足粗车要求；车削时，选择精度高、耐用度好的刀具，以满足加工精度的要求。

为了减少换刀时间，方便对刀，尽量使用机夹刀和机夹刀片，重型立车应尽量使用通用夹具夹紧工件，不要使用专用夹具；零件的定位基准应重合，以减少定位误差。

另外，加工路线要事先确定，要满足加工精度和表面粗糙度的要求；尽可能缩短加工路线，从而减少刀具的空转时间。这样更有利于重型数控立式车床加工过程的顺利完成。

重型立车切削作为制造技术的主要基础技术，随着制造技术的发展，在20世纪末取得了长足的进步，进入了以发展高速切削、发展新的切削技术和加工方法、提供成套技术为特征的新的发展阶段。是制造业中重要工业部门的主要加工技术，如汽车工业、航空航天工业、能源工业、军工、新兴模具工业、电子工业等，也是这些工业部门快速发展的重要因素，然而，数控立式车床不会改变其作为制造技术主要基础技术的地位，重型立车在开环控制伺服电机轴上装有角位移检测装置，通过检测伺服电机的旋转角度，间接检测运动部件的位移并反馈给CNC装置的比较器，与输入指令进行比较，由差值控制运动部件。

为了适应市场和科技发展的需要，满足现代制造技术对数控技术的更高要求，满足数控馈入化、网络化、普及化、个性化、多品种、小批量、柔性化和快速发展的要求，重要的发展趋势是体系结构的开放式数控技术，快速成型、并联机构机床、机器人机床、多功能机床等整机中的制造工艺技术，以及高速电主轴和直线电机，软件补偿精度等单元技术取得突破。
