The Research Of CNC Spinning Machine Alteration Based On Lathe C630

The lathe refit is a means of technical reform that is to make use of the formerly idle and old equipments and give necessary technical reform so as to meet the new demand of production. According to the relative report, at some industrially developed countries, the average tenure of use for the equipment is limited in about 15-20 years and the period of technically aging for equipment is already shorter than 10 years. In those countries mentioned above the old machine tool refit rate exceeded more than 80%.Currently the equipments using in most part of the enterprises in our country were old. The problems of technically aging and inadequate exist obviously, the products produced by those equipments are low in accuracy, bad in surface quality, high in cost and unstable in performance and there are not very competitive in international market. This situation obstructed the forward development of our processing industry.This paper provides a detailed reconstruction scheme for CNC spinning machine based on lathe C630 and makes a feasible analysis to the lathe reconstruction. Moreover the writer completes the calculation of parameters for lathe's key components and checks of the longitudinal and horizontal leading screw. And a hydraulic system was design to adopt the Machine tool alteration.The design and the finite element analysis (FEA) of the integral injector were main parts of this paper. Roller bases which is a key component influenced on the precision of work piece is both the longitudinal block and the guide apparatus of cross blocks. Aimed at the roller bases deeply by the means of FEM. The goal is to reveal the main body of spinning machine. The method adopted and the results obtained have reference value for improving the level of design on Machine tool alteration.The refit machine promoted its processing accuracy and level of automatic control of the parts and greatly improved the productive efficiency and it has the following characteristics: small investment, better efficiency, less refit workload, short period of manufacturing and testing, high utilization rate of old equipment and easily resume its former processing function when stopping production of such parts in future, it is of practicalim portance to the small and middle-sized enterprises.
