摘 要

數(shù)控機(jī)床是裝備制造業(yè)的基礎(chǔ),振興裝備制造業(yè)首先要振興數(shù)控機(jī)床業(yè)。一個國家數(shù)控機(jī)床業(yè)的水平已經(jīng)成為衡量該國制`造業(yè)水平、工業(yè)現(xiàn)代化程度和國家綜合競爭力的重要標(biāo)志,直接關(guān)系到國家經(jīng)濟(jì)建設(shè)和國防安全及戰(zhàn)略地位。數(shù)控車床作為一個重要的組成部分，對其研究有著重要的意義。
CK0620型微型數(shù)控車床是一種多功能的臺式車床。它具有簡單實用、操作方便、高性價比等特點，能實現(xiàn)直線、錐度、圓弧、螺紋等復(fù)雜的零件加工，并可作為教學(xué)用機(jī)床。對其研究,可以對數(shù)控車床的基本原理、基本結(jié)構(gòu)有所了解，為以后的工作打好基礎(chǔ)。
本文主要針對CK0620型車床的主軸系統(tǒng)、進(jìn)給驅(qū)動系統(tǒng)、數(shù)控系統(tǒng)作為主要研究對象。該機(jī)床主軸系統(tǒng)采用變頻電機(jī)驅(qū)動與箱內(nèi)減速器組合，進(jìn)給系統(tǒng)采用步進(jìn)電機(jī)驅(qū)動與滾珠絲桿螺母副傳動組合，使得該機(jī)床結(jié)構(gòu)簡單、操作容易、加工精度較高等特點。

ABSTRACT

NC machine tools is the basis of the equipment manufacturing industry, revitalizing the equipment manufacturing industry is first necessary to revitalize the NC machine tool industry. A country's level of CNC machine tool industry has become of an important sign of the country's manufacturing industry to measure the level of industrial modernization and the country's comprehensive competitiveness , directly bearing on national economic construction and national defense and national security and strategic position. CNC lathe as a key component of the research is of important significance.
Micro-CNC lathe of CK0620 is a multi-functional desktop lathe. It is simple and practical, user-friendly, cost-effective, and other characteristics, to achieve a straight line, taper, arc, thread and other parts of the complex processing, and as a teaching machine. From the research, we can know the basic principle and the basic structure of the CNC lathe, laying a good foundation for future work.
This main content of the paper is studying the spindle system, the feed drive system, the NC system. The machine spindle motor drive system uses frequency reducer combination with the box, feeding system using stepper motor-driven ball screw and nut combination of transmission, making the machine structure is simple, easy to use, high precision machining and other features.


Key words: CNC lathes, spindle system, feeding system, the NC system
