Key Features

● Reinforced Casting & Thermal Treatment: All major components are made from high-strength, dense cast iron, treated with annealing and artificial aging to eliminate internal stress—ensuring long-term accuracy retention and extended machine life.

● Wide Rectangular Hard Guideways: The machine bed features a wide hard rail structure, ground to high precision and coated with wear-resistant guide tape, delivering exceptional vibration damping and rigidity for heavy interrupted cutting operations.

● Triple-Bearing Spindle System: A robust three-bearing spindle configuration provides superior axial and radial rigidity, ensuring smooth rotation and stable cutting performance under high-load machining.

● Integrated Chip Management & Lubrication: Equipped with a side chip removal system for efficient swarf evacuation and a dedicated oil pump that delivers forced lubrication to key components, maintaining stable performance during extended operations.

● Rugged Mechanical Transmission: The mechanically controlled speed and feed system is optimized for both roughing and finishing, ensuring stable power transmission across a wide range of speeds and feed rates.

Frequently Asked Questions

1、What types of workpieces are suitable for your heavy duty lathes?

Minnuo heavy duty lathes are designed for large, long, and heavy components, such as wind turbine shafts, marine propeller shafts, large rollers, pressure vessel flanges, and oil drilling equipment. These machines are ideal for industries like energy, marine, aerospace, and heavy machinery.

2、What is the maximum turning capacity of your heavy duty lathes?

Our standard heavy duty lathes can handle turning diameters up to 2,000 mm, lengths up to 10,000 mm, and load capacities over 15 tons. Custom models can be configured for even larger sizes and heavier components.

3、How do you ensure rigidity and stability during heavy machining?

Minnuo heavy duty lathes feature one-piece cast iron beds, extra-wide guideways, large spindle bores, and reinforced tailstocks. These structural features ensure exceptional rigidity and vibration absorption during heavy cutting operations.

4、Can you recommend equipment if I only have the parts drawings?

Yes! Just send us your part drawings or specifications, and Minnuo’s engineering team will recommend the suitable heavy duty lathe model within 10 minutes. For full production lines, we will provide a tailored solution within 5 working days.

5、Do you offer customization services for heavy duty lathes?

Absolutely! We offer customizations including bed length, spindle bore diameter, main spindle power, chuck size, and steady rest options, as well as integration with automation systems to meet your exact processing needs.

6、How is the quality of your heavy duty lathes guaranteed?

Each machine is manufactured using premium processing equipment, with precision hand scraping of contact surfaces, and undergoes dynamic balancing tests, laser alignment checks, and full-function dry runs before shipment. Inspection reports are delivered with the machine.

7、What is the delivery time for heavy duty lathes?

Standard models can be delivered within 15–20 working days. For large or fully customized machines, the delivery time is usually 30–60 working days, depending on complexity and workload.

8、What after-sales service do you provide for heavy duty lathes?

We offer a one-year warranty, with 24/7 technical support. Our service team provides remote video diagnostics, phone consultations, and on-site assistance to solve any issues quickly. Spare parts support is guaranteed for 10+ years after purchase.
