This series lathes are improved from original model design, new standards are adopted. After improvement, rigidity of spindle system is enhanced and is suitable for powerful and high speed cutting. Feed of carriage in longitudinal and cross are fined, thus the surface quality of parts is improved. The machine is available for turning cylinder and cones, and do the works of end turning, grooving, drilling, boring and trepanning, and also can cut all kinds of inside and outside metric threads, inch threads, module threads, etc. The machine is characterized by compact structure, convenient operation, low noise and high efficiency, and is also provided a complete set of accessories. The machine is especially suitable for various machining industry, such as machine building industry, light-textile industry, petrochemical industry, valve industry, roll industry and so on.SPECIFICATIONS: GH61140J GH61160J STANDARD EQUIPMENT Swing Over Bed: 1400mm 1600mm 4-jaw 1250(1400)mm chuck Swing Over Gap:(GH62100T) -- Follow rest 70~200mm Swing over carriage: 1050mm 1250mm Revolving center Max. turning length: 1000~12000mm Oil gun Max. weight of workpiece between centers: 6000kg Special tools Width of the bed: 755mm 30 " Center sleeve Spindle noses No.: 1:20 Steady rest 70~600mm Diameter of spindle front bearing: 200mm 8 " Auto travel of carriage Diameter of spindle hole: 100mm 4" Auto travel of cross slide Taper hole of spindle: Metric No.140 OPTIONAL ACCESSORIES Number of spindle speeds: 12 Digital readout device Range of spindle speeds: 4.25~192rpm Open type steady rest 480~880mm Main motor power: AC 22 KW Grinder Workpiece held on the steady rest 70~480mm Auto travel of compound slide Section of tool shank: 45 x 45mm 1.8" x 1.8" Max. travel of top slide 350mm Rapid moving speed of tool post Longitudinal 1.2m/min Cross 0.6m/min Metric Threads number and range: 46,1~224mm Inch threads number and range: 46,28 ~ 1T.P.I.
