Model: SLL50 - Linear Guideway
(Guide Roll's turning + Normal parts turning)
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.
