Product Introduction
This series of heavy-duty manual lathes are mainly used for various turning tasks. They can turn the end faces, outer circles, inner holes, metric threads, imperial threads, module threads, diametral pitch threads, etc. of various parts. The upper tool holder can be used to turn short tapers alone, and the upper tool holder can be used in conjunction with the longitudinal feed to turn long tapers. In addition, it also has the functions of drilling, trepanning, and boring. The machine tool has high power, high speed, and strong rigidity. Carbide tools can be used for strong turning to process various ferrous and non-ferrous metals.
Product Advantage
The 1100mm guideway minimizes sag (less than 0.05mm for a 6m workpiece) and ensures straightness within 0.1mm/m, critical for manufacturing drive shafts and hydraulic cylinders.
Capable of handling workpiece weights up to 10 tons (with optional steady rests), these lathes excel in high-load environments such as steel mills and forging plants.
The enclosed lubrication system (2.5L capacity) automatically distributes oil to guideways and gears, reducing lubrication frequency to once per 40 hours. Corrosion-resistant coatings on exposed parts extend service life in humid environments.
Supports metric (0.5–30mm), imperial (4–60 TPI), module (0.5–16mm), and DP (6–80) threads, with a thread dial indicator for precise alignment. The lead screw backlash is adjustable to less than 0.03mm for accurate thread cutting.

Products Uses
1. Large-scale machinery manufacturing
In shipbuilding, it is used to process key components such as large ship crankshafts and propeller shafts. These components are large in size and heavy in weight, and have extremely high requirements for processing accuracy and equipment load-bearing capacity. Heavy-duty general-purpose lathes can meet their processing needs and ensure the reliability and stability of the components. In the manufacturing of large-scale power generation equipment, such as steam turbine rotors for thermal power generation and main shafts of hydro-turbine generators, heavy-duty general-purpose lathes can perform high-precision turning processing to ensure the efficient operation of the equipment.
2. Mining machinery processing
Large gears, shaft parts, and cylinders in mining machinery usually need to be processed on heavy-duty general-purpose lathes. Through the precision processing of heavy-duty general-purpose lathes, their dimensional accuracy and surface quality can be guaranteed, and the service life and work efficiency of mining machinery can be improved.
3. Metallurgical equipment manufacturing
Heavy-duty general-purpose lathes can turn rollers to achieve precise sizes and surface shapes to meet the requirements of rolling steel of different specifications. In addition, large reducer gear shafts and other parts in metallurgical equipment also need to be processed by heavy-duty general-purpose lathes to ensure their transmission accuracy and load-bearing capacity.
4. Defense industry
Heavy-duty general-purpose lathes play an important role in the manufacture of large-scale weapons and equipment such as tanks and artillery. With their high precision and high rigidity, heavy-duty general-purpose lathes can process high-quality parts that meet defense requirements and ensure the performance and reliability of weapons and equipment.

FAQ
What is the maximum cutting diameter?
The CW61140E handles a maximum cutting diameter of 1400mm (over bed) and 800mm (over cross slide), while the CW61160E increases this to 1600mm (over bed) and 900mm (over cross slide).
Can the tailstock be adjusted for off-center machining?
Yes, the tailstock base features T-slots for lateral adjustment, allowing offsetting by up to ±1mm for taper turning (angles up to 3°) without reconfiguring the workpiece.
Is the lathe suitable for high-speed cutting?
While optimized for heavy-duty, low-speed cutting (3.15–100 RPM for roughing), it supports moderate speeds (100–315 RPM) for finishing operations on aluminum and brass.
What coolant system is recommended?
A 0.125kW high-pressure coolant pump (10 bar) is included, with a flexible hose and adjustable nozzle to direct coolant to the cutting zone. Water-soluble coolant (5–8% concentration) is recommended for optimal chip evacuation and tool life.
