普通車床生產(chǎn)廠家的車床主軸在軸承上運(yùn)轉(zhuǎn)的平穩(wěn)性直接影響工件的加工質(zhì)量，一旦主軸的旋轉(zhuǎn)精度降低，則機(jī)床的使用價(jià)值就會(huì)降低。進(jìn)給箱：又稱走刀箱，進(jìn)給箱中裝有進(jìn)給運(yùn)動(dòng)的變速機(jī)構(gòu)，調(diào)整其變速機(jī)構(gòu)，可得到所需的進(jìn)給量或螺距，通過(guò)光杠或絲杠將運(yùn)動(dòng)傳至刀架以進(jìn)行切削。Our company is located in Xuyi economic and Technological Development Zone, the lobster capital of China, 100 kilometers away fr
