一、前言加工淬硬模具上的精密孔系,始终是对模具制造技术的挑战。如果不是简单的圆孔,而是连续轨迹曲面,又要保持凸凹模均匀而小的间隙,则就更困难了。我们如果利用具有连续轨迹计算机数字控制(简称CNC)的坐标磨床来加工,就能可靠地实现模具的技术要求,并能大大缩短圆孔和曲面的加工时间,以及能克服以往加工的困难及型面交、切点处不光顺的疵病,达到精度高的目的。因此,连续轨迹的CNC坐标磨床是现代磨具制造车间不可缺少的设备。二,CNC坐标磨床的性能连续轨迹CNC坐标磨床具有很高的加工精度。它的定位精度一般为0.003mm,加工坐标精度可稳定保证在0.005mm以内。由于这类机床有良好的重复定 First, the preface Processing hardened mold on the hole, is always the mold manufacturing technology challenges. If it is not a simple round hole, but the continuous track surface, but also to keep the punch and die uniform and small gap, then more difficult. If we use the continuous track computer numerical control (CNC) for the coordinate grinder to be processed, we can reliably achieve the technical requirements of the mold, and can greatly shorten the processing time of the hole and the surface, as well as to overcome the difficulties and the type of processing Face to face, cut-point at the defect, to achieve the purpose of high precision. Therefore, the continuous trajectory of CNC grinding machine is an indispensable equipment in the modern abrasive manufacturing workshop. Second, CNC coordinate grinder performance Continuous trajectory CNC coordinate grinder with high processing accuracy. Its positioning accuracy is generally 0.003mm, processing coordinates accuracy can be guaranteed within 0.005mm. Because of this type of machine has a good repeat
