摘    要
金屬切削機(jī)床是用切削的方法將金屬毛坯加工成機(jī)器零件的機(jī)器，它是制造機(jī)器的機(jī)器，又稱為“工作母機(jī)”或“工具機(jī)”。
在現(xiàn)代機(jī)械制造工業(yè)中，金屬切學(xué)機(jī)床是加工機(jī)器零件的主要設(shè)備，它所擔(dān)負(fù)的工作量，約占機(jī)器總制造工作量的40%～60%。機(jī)床的技術(shù)水平直接影響機(jī)械制造工業(yè)的產(chǎn)品質(zhì)量和勞動(dòng)生產(chǎn)率。
儀表機(jī)床具有價(jià)格便宜，重量輕，占地小，操作維護(hù)簡便方便的特點(diǎn)，儀表機(jī)床仍然具有很高的市場(chǎng)價(jià)值。

Abstract
Metal-cutting machine tools is the method of cutting metal machine parts into a rough processing machine, it is a machine manufacturing machines, also known as "machine tool" or "machine tools." Metal-cutting machine tools is the method of cutting metal machine parts into a rough processing machine, it is a machine manufacturing machines, also known as "machine tool" or "machine tools."                    
In modern machine building industry, metal cutting machine learning is the main processing equipment, machine parts, it has to assume the workload, accounting for the total manufacturing work machines 40% ~ 60%. The skill level of machine tool directly affects the mechanical manufacturing industry product quality and labor productivity.
Instrumentation machine with cheap, light weight, occupies an area of small, simple and convenient operation and maintenance features, instrumentation machine still has a high market value.     
Key words: Instrument Machine Tool
