·This series of lathe use the cylndrical surface,circular conical surface,fracture surface,surface of revolution,chaffcutter,screw thread and boring of the black metal,non-ferrous metal and part of the nonmetallic parts to make the rough and finishing.And it suitable for the industry of ships,locomotives,areospace,military and metallurgy which need to machining effectively,batchly and precisely of the rotating parts.The lathe is widely used,simply operated,easily finished and adaptable for craft.And it is the ideal large mechanical processing equipment. ·The body of the lathe adopts the organization of whole double rectangular intermediate frequency quenching process guide,which has strong rigidity rigidity,large loading capacity and stable accuracy retentivity. ·The main transmission of lathe is drive by a dc moter,and after the four grade hydraulic automatic transmission,leading the machine to get four section stepless speed regulation.The main spindele box has large size and three point form supported by the heavy loading bearing,which making the rotation stable and the lathing subtly. ·Spindle uses the hydraulic four grades frequency conversion to the stepless speed regulating.And this lathe is the ideal products for batch processing large and medium sophisticated parts. |
