Research On 30t Boring And Milling Machine Cnc Retrofitting

Equipment is main production implements of enterprise and is very important label for modernizes. Adopt new techniques and technical accelerating enterprise equipment improves is that country's equipment policy but also one item important strategic task of enterpriseThat 30T boring and milling machine was introduced to Shenyang Blower Works (Group) Co., Ltd from American Lucus Company in 1980. After several years the machine tool was old. NC and spindle and servo unit was aging. SBW sets up a project to retrofitting on the machine with advanced technology.This paper introduces how to retrofitting on the CNC machine tool are as follows.(1) Fagor 8025 CNC applying, CNC parameter optimizing and PLC program and M function code editing(2) CNC machine tool enclosed control with the optical scales.(3) DC servo driving device reforms on the DC servo motor; the 590 DC digital converter retrofitting on spindle.By applying a series of advanced technology retrofitting on 30T boring and milling machines that have made the function of 30T boring and milling machine tool advanced and improved. And have strengthened machine tool reliability. This project application having guiding for NC machine tool changed to CNC machine tool. Fagor 8025 CNC and KSA63 wide range speed control servo unit and 590 DC digital converter and optical scales enclosed control of application show a way to retrofitting. After retrofitting on the machine tool have improved the accuracy and the efficiency and reached currently CNC machine tool advanced level.
