PC50 CNC Boring And Milling Machine Upgrade

PC50 type CNC boring and milling machine is the one xi 'an coal company imports from the United States, and it is the main equipment that our company process the compnents of a machine such as radial, traction, the connection. After 20 years of use, reliability and accuracy of machine are reduced, effectiveness of the control system is brought down, the rate of being faulty is high. With the special support of PC50 type CNC boring and milling machine of xi'an coal company upgrade, the article is mainly focus on the study of the key technology of upgrading, and restoring the machine back to the same type of new purchase equipment of the same processing capability.This article is mainly from the following three aspects to discuss the upgrade process of nc machine tools:(1) To detect PC50 type CNC boring and milling machine technical parameters of the status quo, to analyze them comprehensively, to formulate the technical requirements of upgrading, and to complete the general design about the machine tool upgrading. On this basis, to determine the detailed design about mechanical unit maintenance, electrical transformation, upgrading scheme(2) To research and formulate the detailed design about machine tool servo drive,numerical control system upgrade project, to complete the drive motor, ball screw, bearing,measurement and other key components of selection design, to select the appropriate data system which is used to develop and debug.(3) In order to satisfy the machine tool upgrading technical requirements, with the new CNC, electrical hardware, electrical control part to carry on the design of nc machine tools,the article will analyze the original machine action sequence and process,and complete with auxiliary motion of the machine tool, protection device, the control unit of hydraulic system functions such as program development work.In this article, the author studies on upgrading the technology, effectively improve the function of PC50 type CNC boring and milling machine and machining precision, has reached the expected goals, also accumulate experiences for the subsequent equipment upgrades for xi'an coal company.
