防护装置

The possiblehost objective reason all is very many, but, our country numericalcontrol engine bed function part development backwardness -- varietyfew, unit technical level low, performance quality insufficientlystable, the cost stays at a high level, the delivery insufficientlywas prompt and so on -- not to be able to satisfy the numericalcontrol engine bed main engine product need to develop, had noalternative but to say was most direct, the most main reason, Becauseall numerical controls engine bed all is by each kind of function part(including host 轴头, straight line rolls guide rail, ball bearingguide screw vice-, numerical control tool rest, knife storehousemanipulator, rotary table, numerical control servosystem, surveyfeedback as well as safe protective equipment and so on), the functionpart which on foundation rack and so on the lathe bed, column thecollection attire becomes is the numerical control engine bedimportant component, moreover is the indispensable part.

可能主客观原因都是很多的，但是，我国数控机床功能部件的发展落后──品种少，单元技术水平低，性能质量不够稳定，成本居高不下，交货不够及时等──满足不了数控机床主机产品发展的需要，不能不说是最直接、最主要的原因，因为所有的数控机床都是由各种功能部件（包括主轴头、直线滚动导轨、滚珠丝杠副、数控刀架、刀库机械手、回转工作台、数控伺服系统、测量反馈以及安全防护装置等）在床身、立柱等基础机架上集装而成的，功能部件是数控机床的重要组成部份，而且是不可或缺的部份。
