Republic Lagun Machine Tool ATV-914-HC-ET Ultra Precision Lathe


  • Extreme accuracy, high precision pre-loaded angular contact ball bearing spindle, permanently lubricated.
  • Guaranteed spindle runout of 50 millionths of an inch, in a controlled environment.
  • Digital or Electronic Threading makes threading on a chucker lathe easier than ever. The Touch screen LCD allows to select thread pitch. Choose target thread per inch or mm pitch on screen, set spindle rpm and start threading just like on conventional lathes. Simple no threading attachment. No threading gear box. Less moving parts, quiet operation; maintenance free design. Servo driven design. An internal servo motor drives the leadscrew so the feed rate is synchronized to spindle rpm’s. (see Note #1 bellow)
  • Electronic Variable Speed (EVS) drive providing spindle speeds 50~4,000 RPM, eliminating vibration associated with belt vari-drive systems.
  • Hardened and precision ground alloy tool steel bedways.
  • Hardened and precision ground spindle.
  • 5C lever type ball bearing collet closer for fast-lever collet chucking with a single movement.
  • One-piece headstock and bed construction.
  • Control console with load meter, digital display of spindle RPM, speed selection potentiometer, forward-stop-reverse switch and emergency stop.
  • The control console is integrated with a Digital Read Out or (DRO) with touch screen functions for an all in one versatile machine. With linear Mitutoyo scales for X and Z axis feedback.
  • Pre-loaded ball bearing 8-station indexing turret with locking lever.
  • Full bearing carriage with Turcite-B anti-friction material and precision gears and clutches, completely enclosed in a special oil bath system.
  • Independent electric variable feeds to carriage and cross slide by D.C. Motor. Feed rates can be changed instantly at any time, even while cutting.
  • Easy reading dial for cross feed turret with pointers and easy to read, smooth carriage handwheel.
  • Carriage slide and bed ways are pressure lubricated to insure long life.
