Precision Lathe Gh1640zx / Gh1660zx / Gh1860zx / Gh1880zx)

FEATURES:The surface of the bedways is hardened and precision ground. The design of the main drive is optimized and the gears in the headstock are precision ground.The spindle bore size is 80mm. The spindle system is high in rigidity and accuracy. There is no vibration when turning with a cutting depth of 10mm.There is no need of changing gears. The machine can turn about 200 kinds of metric, whitworth, module and D. P. Threads including special whitworth threads such as 7-1/2, 9-1/2, 10-1/2, 11, 11-1/2, 13, 13-1/2, 19, 27t. P. I. And pipe threads.An automatic stopping device is used to realize automatic stop for the machining of a certain length workpiece, which is safe and reliable. A pedal or electromagnetic braking device stops the machine quickly and effectively.ITEMGH1640ZX)MACHINING Max.swing diameter over bedФ400mm Max.swing diameter over carriageФ200mm Max.swing diameter in gapФ600mmMax.workpiece length1000mm Effective gap length200mmSPINDLE Spindle boreФ80 Taper of boreM.T.No.7 Number of speed12 Range of speed42-1800rpmTHREAD CUTTING Metric range/No.0.5~20mm/24 Whitworth range/No.72~1-5/8T.P.I/61 D.Prange/No.96~3-1/4D.P/45 Modulerange/No.0.25~10M.P/20FEEDING Longitudinal0.04~2.46mm(0.0015"~0.00913") Cross0.02~1.23mm(0.005"~0.0365")TAILSTOCK External diameterФ75mm Taper of boreM.T.No.4 Max.traverse130mmOTHER Max.travel of compound rest130mm Max.cross slide travel280mm Max.size of tool shank(WxH)25x25mm Power of main motor5.5kw Overalldimensions(LxWxH)2310/2810x1100x1255mm Net weight2250/2550kgRODUCT FEATURES:
