五、关于改装设计几个问题的商讨(1)如何正确选用改装方式已如前述,由集体传动改为单独传动,一般有两种方式。一种是增设附属变速箱,改装的工作量较大,因此耗用的费用也大,制造变速箱的工艺较复杂。但是通过这种改装,可以根据机床床身及几个主要构件的强度储备与刚性,而适当提高机床的切削功率与转速。另外一种则是保留原有的塔轮传动部份,只是单纯地将传动系统由集体传动改为单独传动。这种方案耗用的费用较少,对原有机床没有变动或很少变动。用这种改装方案,提高机床的切削功率与转速的可能性不大;但由于这种改装的工作量小,耗用费用较少,更因工艺要求低,一般
Fifth, on the conversion design of several issues of discussion (1) How to correctly select the modified way As mentioned above, the collective transmission to a separate drive, there are two ways. One is to add ancillary gearbox, modification of the workload, so the cost is also large, the process of manufacturing gearbox is more complicated. But through this modification, according to the machine bed and several main components of the strength of reserves and rigidity, and appropriate to improve the cutting power and speed of the machine. The other is to retain the original part of the tower drive, just simply the drive system from a collective drive to a separate drive. The cost of this program is less, no change on the original machine or little change. With this conversion program to improve the cutting power and speed of the machine is unlikely, but due to the workload of this modification is small, less cost, but also because of the low process requirements, the general
