Heavy Duty Precision & Porwerful Lathe
HG-660 / 760 / 800 / 840 X 1200, 1700, 2200, 3200, 4200, 5000

*Standard accessories shall be subject to the quotation.

This machine is suitable for heavy cutting, easy operation, high tenacity, stability and heavy workload, which are good for heavy turning of mold, gear, wheel, shaft, central spindle etc.

  • 1. Base
    • Designed for heavy duty cutting; this base is made of high quality Mechanite casting and design of rigid construction increase the loading capacity and processing stability.
  • 2. Compound rest
    • Adopt 4-point tightened the rest to ensure the stability of compound rest. Wider tool post and top slide are induction hardened and ground precisely to promise a long life.
  • 3. Spindle & headstock
    • 12-step speed change, the spindle is supported by three points with bearings. G ears and spindle are made of high quality alloy carbon treated, spindle bore 80mm or 105mm, precision ground to acquire much superior hardness and tenacity.
  • 4. Gear box
    • (1) Adopt metric / inch gearbox for inch, metric, DP, MP, threading and multiple threads, all
      function is reached without any change gear, wide and complete range of threads and
      operating easily to improve production efficiency.
    • (2) Two T.P.I per inch is available for inch threading, which provide wider threading range
      than other similar specification of lathe and more convenient for operating.
  • 5. Carriage & saddle
    • The contacting surfaces with bedways are pasted with Turcite-B. The slot surface of dovetail slide way has been ultra-frequency heat treated (induction hardened and ground) to promise a long service life.
  • 6. Apron
    • Enforced oil feeding device, which ensure the slide ways with proper lubricating, effectively keep high accuracy turning, reduce the wearing of slide ways. Provide safety device to prevent the collision while turning from danger.
  • 7. Cross slide screw
    • Two point support and suitable for heavy duty turning.
  • 8. Tailstock
    • Two steps fixed device for Tailstock increase the capacity of heavy duty turning and drilling stability.
    • Two steps feeding device for easy operation.
  • 1. Follow rest
  • 2. 4-jaw independent chuck 20", 25"
  • 3. Face plate with 4-jaw 24", 26", 28", 30"
  • 4. Longitudinal & cross rapid feeding
    - only for HG-1200, 1700
  • 5. Halogen light
  • 6. Digital readout
  • 7. Back splash guard
  • 8. Quick change tool post (instead of tool post) (standard or Equrpean style)
  • 9. CE equipment
  • 10. Taper turning attachment
  • 11. Grinder
  • 12. Hydraulic copy attachment
  • 1. XZ-axes auto lubrication system
  • 2. Metric/ lnch gear box
  • 3. Coolant device
  • 4. Longitudinal apron motion feed
  • 5. Tailstock two steps device
  • 6. 3-jaw scroll chuck
  • 7. Back plate of chuck
  • 8. Steady rest
  • 9. Center sleeve
  • 10. Dead center
  • 11. Tool post screw wrench
  • 12. Level pads
  • 13. Tools & tool box
  • 14. Operation manual
  • 15. Longitudinal & cross rapid feeding
    - only for HG-2200, 3200, 4200
