But because of the number of axis increased , the factor and the complexity that influent the working accuracy increased too 但是由于聯(lián)動軸數(shù)的增加,影響機床加工精度的因素及復(fù)雜性也相應(yīng)增加。
The machine is characterize by good rigidity 、 high working accuracy easy in operation . it can be operated with high speed and heavy cutting load and is efficient in production 本機床具有剛性好、強度大、精度高、操作方便、調(diào)整簡單等特點,能進行高速及重負荷切削,有很高的生產(chǎn)效率。
The enactment of the cutter is one of the important factor , in the aspect of cutter compensation , it only has radius compensation and length compensation in planar . in three - dimensions , especially on five - axis tandem drive numerical control machine , it still need further study . so in order to improve the working accuracy of numerical control machine , the study of five - axis cutter radius compensation in this paper is very useful 刀具的設(shè)定是影響機床加工精度的重要因素之一,就刀具補償而言,目前的數(shù)控機床只是在二維空間內(nèi)具有刀具半徑補償、及刀具長度補償,三維空間內(nèi)的刀具補償,特別是在五軸聯(lián)動數(shù)控機床上,由于刀具擺動軸的出現(xiàn),使得刀具補償難以實現(xiàn),還需進一步深入研究。
A good vibration damping measure is very important for the enhanced working accuracy of machine tools , especially for that of ultra - precision machines . taking the sub - micron cnc ultra - precision turning machining for an example , this paper illustrated the vibration damping design features on configuration and material selecting , and put the emphasis on the vibration analysis of air spring vibration and aero - static bearing spindle . the theoretical analysis and experimental result have proved that the vibration damping measure is practical 良好的減振措施是提高機床,特別是超精密機床加工精度的重要技術(shù)之一.本文以亞微米超精密車床為研究對象,論述了該機床從結(jié)構(gòu)到材料選取上的減振特點,并重點進行了空氣彈簧和空氣靜壓軸承主軸減振分析,由理論分析和實驗表明:減振措施合理,減振效果良好
In case that the rolling bearings with no inner ring or outer ring and without inner and outer rings ars selected , the sueface haedness of the holes or housing holes as race , the working accuracy and surface quality shall be similar with the race of bearing rings in order to guarantee that loading capacity and operating performance are identical with the bearings equipped with rings 選用無內(nèi)圈或無外圈,以及無內(nèi)、外圈滾動軸承時,作為滾道的孔或外殼孔表面的硬度、加工精度和表面質(zhì)量應(yīng)與軸承套圈的滾道相仿,以保證負荷能力和運轉(zhuǎn)能與有套圈軸承相同。
