Heavy Duty Lathe

The heavy-duty lathe is engineered for precision turning and cutting of large workpieces and steel rods, ideal for industries like oil pipe networks, aerospace, and heavy-duty shaft processing. Its robust design ensures durability and high performance under demanding conditions. Key features include:

Reinforced Base: One-piece casting with extra support for large workpieces and heavy cutting.
Spindle & Headstock: 9″-20″ bores, turbine speed change, alloy gears, and sealed oil lubrication for low-noise durability.
Quick-Change Gearbox: Universal metric/inch threading without gear changes for efficiency.
Durable Construction: FC-30 steel, annealed, high-frequency treated, and precision-ground for long service life.

It is suitable for turning and cutting of large work piece and steel rod materials for heavy industries like oil pipe network, aerospace and heavy-duty shaft processing.

1. Base
- (1) One piece casting work with reinforced inner structure, extra 3rd support to be suitable
  for processing of large work piece and
  enhanced heavy-duty cutting ability.
- (2) The gap part base special with reinforced structure, it is no influence on cutting stability
  to break the gap for necessary.
2. Spindle & Headstock
- (1) Bore 9″, 10″,12″, 15″, 20″ (only fit to swing over bed over 1120mm)
- (2) Turbine speed change, turbine speed change mechanism with on easy speed jumping and
  three-point support for
  the box.
- (3) Fitted with adjustable, electromagnetic brake for easy braking adjustment according to
  different work piece materials and speed.
- (4) Gear and shaft are made of super alloy material with bearings to offer durable cutting
  and low production noise.
- (5) Sealed oil bath lubrication system with enforced oil supply by mechanical pump to
  achieve better lubrication effects.
3. Gear box
- Adopt quick-change universal 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.
4. Apron
- Equipped with rapid feeding, rapid transmission, forward / reverse movement, and safety device matched with sealed oil bath auto-lubricating system.
5. Saddle
- Anti-friction processed surface with regular oil injection, lubricated and friction endurable.
6. Tailstock
- Two stage feeding device, swing arm movement to have smooth and labor saving operation.
7. Electrical control
- 20HP / 30HP Motor, 2 stage safety start-up device and overloading power cut system.
8. Casting
- FC-30 steel are used for main structures like base, spindle, saddle and Tailstock, which are annealed and have no deformation.
9. Processing
- Base, spindle, saddle, dovetail slot surface of cross slide, top slide and tailstock quill are high frequency treated, precision ground
  for extended service life.
