Slant Bed CNC Lathe - SLL50

l  FEATURES:

l  Advanced Technology: Developed on technology of CINCINNATI, USA.

l  Strong Rigidity: 45° Slant type one-piece-bed achieving very strong rigidity.

l  Compact Design, Friendly Operation!  Linear Guide Way

l  Suitable turning for cylinder’s O.D & I.D, taper, thread, arc surface, slot, chamfer, and complex curve’s turning, boring. Widely used for automotive, aerospace, military, petrochemical, mechanical industries…

l  Built with Germany SIEMENS 828D CNC system, or JAPAN FANUC CNC system.

l  Automatic Chip Conveyor: Built-in fully automatic chip conveyor

l  Hydraulic controlled tailstock quill

l  Hydraulic Tool Turret: Fast movement, accurate positioning without shock. Strong hydraulic clamping is good for heavy turning.

l  High Precision Retention: All main casting parts have had TWICE aging treatments for stress relief.

l  High Accuracy: Main key castings were machined by Japan 5-face CNC machining center.

l  Linear guideway used on saddle for smooth & accurate movement.

l  Main motor & Two axis motors are Servo Motors with large power & heigh performance.

l  Direct-connection between servo motor with precision ball screws, without gap, for smooth, stable, and reliable rotation. Guarantee machine’s positioning accuracy.

l  Large flow cooling: Good for reduce heat distortion during machining.

l  Centralized automatic lubrication pump: Good for lubrication, extend machine’s working life and accuracy.

l  Spindle has good support with 3 pcs. precision bearings at front & 2 pcs. precision bearings at rear. Ensure the spindle having maximum axial and radial rigidity for better finishing quality. The high torque spindle motor provides heavy duty cutting to raw material.  

l  Electrical cabinet wiring according to GB5226.1 standard, adopts heat exchanger to discharge heat air quickly and keep constant temperature inside the cabinet.

l  Safety & comfortable working environment to operator by its protection system.
