產(chǎn)品概述 Product Description   

    CG系列重型臥式車床為我公司根據(jù)長期生產(chǎn)臥車的經(jīng)驗(yàn)，采用國際上先進(jìn)的設(shè)計(jì)手段和制造技術(shù)，執(zhí)行國家現(xiàn)行最新精度標(biāo)準(zhǔn)，精心設(shè)計(jì)的一種集電氣、自動控制、液壓控制和現(xiàn)代機(jī)械設(shè)計(jì)等多學(xué)科、多門類的精密制造技術(shù)為一體的機(jī)電一體化機(jī)床產(chǎn)品。機(jī)床結(jié)構(gòu)性能適用，機(jī)床具有動靜態(tài)剛度高、使用壽命長、加工效率高、各項(xiàng)功能安全可靠、操作方便和造型美觀等特點(diǎn)。

1、CG系列重型臥式車床適用于高速鋼、硬質(zhì)合金鋼等刀具，對黑色金屬、有色金屬和部分非金屬的軸類、圓筒類和盤類零件，進(jìn)行車削外圓、端面、切槽、切斷、鏜孔等

2、CG系列重型臥式車床主傳動與進(jìn)給傳動采用分離式結(jié)構(gòu)。

3、CG系列重型臥式車床床身采用整體三導(dǎo)軌，床身導(dǎo)軌采用磨削加工或鑲鋼結(jié)構(gòu)的低磨擦副滑動平導(dǎo)軌。

4、CG系列重型臥式車床的主傳動由直流電機(jī)驅(qū)動，經(jīng)機(jī)械三檔變速，實(shí)現(xiàn)主軸的轉(zhuǎn)速范圍。

5、主軸箱主軸為穿軸式結(jié)構(gòu)，采用高精度可調(diào)徑向間隙的雙列短圓柱滾子軸承，經(jīng)優(yōu)化設(shè)計(jì)采用較大的主軸直徑及最佳支承跨距，提高了主軸的回轉(zhuǎn)精度和動、靜剛度。主軸上的頂尖采用法蘭式短錐柄結(jié)構(gòu)，提高了頂尖與主軸的連接剛度。

6、刀架橫向采用梯形絲杠或滾珠絲杠，縱向采用高精度齒條及雙齒棒消隙結(jié)構(gòu)，提高了刀架的傳動精度。

7、尾座為整體箱形結(jié)構(gòu)，套筒內(nèi)的芯軸采用高精度可調(diào)徑向間隙的雙列短圓柱滾筒內(nèi)的芯軸采用高精度可調(diào)徑向間隙的雙列短圓柱滾子軸承，頂尖為法蘭式短錐柄頂尖，使尾座具有很高的剛度，套筒和尾座均為機(jī)動，并裝有液壓測力裝置。

8、可根據(jù)用戶要求，提供雙刀架、銑鏜裝置、磨削裝置、冷卻液裝置等。

    CG series heavy duty horizontal lathe is an electromechanical machine tool integrating electrical control, hydraulic control, modern machinery design and other disciplines, Our heavy duty horizontal lathe executes national lastest accuracy standard, which is designed and manufactured according to the international advanced technology and our many years experience. This kind of horizonta lathe has a perfect structure performance with high rigidity, longer service life, higher efficiency, safe and stable function with easy operation. 

1.CG series Heavy duty horizontal Lathe Series are widely used for turning not only the non-ferrous metals like various structure steels, casting steels and irons, but also the external/internal cylindrical / conical/ spherical surfaces, thread of non-metal materials and all kinds of the surface of curve rotary body.

2.Main transmission and feed transmission of CG series heavy duty horizontal lathe adopts separate structures. 
3.The machine bed of CG series heavy duty horizontal lathe adopts 3 guide rails, which adopts grinding process or inlaid steel structure of low friction & sliding flat guide rail.
4.The main transmission of CG series heavy duty horizontal lathe is driven by the AC motor directly.  It realizes different spindle speeds by 3 different mechanical gear shifts.

5.The main shaft of headstock is a cross-axle structure, which adopts double-row short cylindrical roller bearing with high precision and adjustable radial clearance. and adopts a larger spindle diameter and the best supporting span through optimization design, which improves the rotary accuracy and dynamic and static stiffness of the spindle.The center on the spindle adopts the flange type short taper shank structure, which improves the connection rigidity between the center and the spindle.
6.The horizontal direction of cutting tool carriage uses trapezoidal screw or ball screw, and the longitudinal direction adopts high precision gear and double-teeth rod gap clearance structure. Which improves the transmission accuracy of cutting tool carriage.

7.The tailstock is a kind of intergal box structure, the inner shaft adopts double-row short cylindrical roller bearing with high precision and adjustable radial clearance, and the center is a kind of flange type short taper shank, so that the tailstock has high rigidity. The sleeve and tailstock are both automatic and driven by the motor and equipped with hydraulic force measuring device.

8.This kind of heavy duty horizontal lathe can be also installed double cutting tool carriages, milling & boring device, and cooling device.
