机床参数保护导致的，应该改一下参数
7 o( X8 l1 Y: O. a9 {7 w1 r" z
我公司代理多种品牌的数控车床和车铣复合机，立式/卧式加工中心，数控钻攻中心的销售,维修，价格从几万到几十万都有，精度要求有很多方法可以做到，如果您对数控机床的加工精度要求很高，那么你必须要对加工的工件进行精度误差检测吧？这样误差量出来了的话，就是精度一般的数控机床，有经验的加工师傅也可以做出你想要的高精度;就算是使用一台价值200万的机床加工工件也是需要检验加工工件尺寸的，并且第一件工件也是需要调试好多次才会稳定加工尺寸的。现在有的台湾，日本品牌的数控机床推销员夸张的说：他们的定位精度可以做到0.005毫米，其实使用电机驱动丝杆定位的数控机床正常情况下不可能达到0.005毫米的定位精度，因为丝杆是有热胀冷缩性质的，1米长的丝杆每升高5摄氏度就会延长0.005毫米，但是加工零件精度要想控制在0.005以内还是有方法的，例如:1, 补偿加工程序坐标, 这是国内外一般数控系统都可以做得到的，只是这种方法需要机床操作人员修改程序或者刀具补偿值，2，另外一个方法就是加装光学尺，这样可以实时测出这个热胀冷缩量，再把这个误差量进行实时修正，目前任何数控系统都可以做到这一点，关键是要加装光学尺；3，第三个方法就是在恒温车间，做好温度掌握心中有数，在温度比较稳定的情况下精加工。现在国产机床的生产工艺和技术能力都和国外品牌是一样的， 机床的关键零部件也都是完全一样的采用世界知名品牌的。这就决定了质量精度也是同一标准范围；
