Best-Selling Flat Bed Cnc Lathe - CNC horizontal lathe machine SK61128 series – Premach

Property of the lathe

Mated with FANUC, SIEMENS or other CNC system, with programmable control and CR display. AC servo motor is used for longitudinal and transversal feeding, pulse encoder is used for feedback.
There are four kinds of main drive of turning for different model: manual 21 kinds with 3.15- 315r/min, 2.5-250(21)r/min, 2-200r/min and four stepless speed change driven by servo spindle motor, which increases the constant power range. Two linkage control axes, Z axis and X axis, use ball screw pairs and AC servo motors to achieve longitudinal and lateral movement. The semi closed loop control has good positioning accuracy and repetitive positioning accuracy.
Wide cutting range, can process outer circle, inner hole and end face. Grooving, processing conical surface, chamfering, conical or cylindrical thread and arc surface.
The bed surface of the machine is of Flat-V structure. It is iron cast with high-strength resin sand.
The bed surface is subject to medium frequency quenching treatment. The hardness is HRC50.
The quenching depth is deep, which is conducive to the second regrinding of the machine tool.
The machine body has strong rigidity, large bearing capacity and good stability. The carriage is treated by sticking plastic (polytetrafluoroethylene soft belt). Because the polytetrafluoroethylene material contains lubricating elements, the difference between the dynamic and static friction coefficients are small, which greatly reduces the friction between the drag plate and the guide way surface of the bed and prevents creeping. The machine bed is cast with an arch gate for backward chip removal, and the chips are directly discharged to the chip receiving tray, which is convenient for chip removal and cleaning.
