Heavy Duty Lathe

This heavy-duty lathe is ideal for turning and cutting large workpieces and steel rods in oil, aerospace, and shaft processing. Its robust cast base ensures stability, while the 9″–20″ spindle with turbine speed change delivers quiet, precise performance. A quick-change gearbox enables versatile threading, and the rapid-feed apron, anti-friction saddle, and two-stage tailstock enhance efficiency. Made with FC-30 steel and powered by a 20HP or 30HP motor, it offers durability and safety.

Robust Base: One-piece cast with reinforced structure for stable heavy-duty cutting.
Versatile Spindle: 9″–20″ bores with turbine speed change for precise, quiet operation.
Efficient Gearbox: Quick-change for inch, metric, DP, MP, and multi-threading.
Durable Build: FC-30 steel, high-frequency treated for long-lasting performance.

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.
