1. What is the QJ-40 Rod Metal Thread Rolling Machine used for?

The QJ-40 is used to form threads on metal rods by cold rolling, producing strong, precise threads at high speed for workshop and production environments.

2. What are the maximum rod diameter and pitch the QJ-40 can process?

Maximum processing diameter is 42 mm and maximum processing pitch is 6 mm as specified for the QJ-40.

3. How fast can the QJ-40 produce threaded rods?

The QJ-40 has a high production rate of up to 130 pieces per minute.

4. What spindle speeds does the machine offer?

Spindle speeds are selectable via exchange gears: 39, 49, 66 and 82 r/min.

5. What are the rolling wheel dimensions and spindle bore?

Rolling wheel outer diameter ranges from 120 to 170 mm and the inside diameter (spindle bore) is 54 mm.

6. What are the machine power specifications?

The specification lists spindle power 505 kW, hydraulic power 202 kW and cooling power 125 W. Because some listed power values appear unusually large, confirm final electrical requirements with the manufacturer or supplier before installation.

7. What are the machine dimensions and weight?

Overall dimensions are 1600 × 1400 × 1200 mm. Weight is specified as 1800 kg + 50 kg.

8. What materials can be thread rolled on the QJ-40?

The QJ-40 is suitable for common rod metals such as carbon steel, stainless steel, brass and aluminum. For specific alloys, diameters and hardness levels, confirm compatibility with the supplier to ensure proper die selection and process settings.

9. How difficult is it to operate the QJ-40?

The QJ-40 is described as user-friendly with straightforward controls; operators can learn basic operation quickly. Proper training on setup, die selection and safety procedures is still recommended.

10. What routine maintenance does the QJ-40 require?

Regular maintenance includes checking and lubricating bearings and gears, inspecting and replacing rolling wheels/dies as needed, monitoring hydraulic fluid condition and levels, cleaning and maintaining the cooling system, and checking fasteners and alignment.

11. What safety precautions should operators follow?

Operators should use appropriate PPE (safety glasses, gloves where safe, and hearing protection), ensure all guards are in place, follow lockout/tagout procedures for maintenance, and be trained on the machine's emergency stop and safe operating limits.

12. Can I use custom thread profiles or special dies with the QJ-40?

Yes — the machine accepts rolling wheels/dies within the specified outer diameter range (120–170 mm) and spindle bore (54 mm). Custom profiles are possible; contact the manufacturer or tooling supplier for custom die design and fitment details.

13. What thread quality and tolerances can I expect from rolled threads?

Thread rolling produces strong, accurate threads with excellent surface finish and material grain flow. Achievable tolerances depend on die precision, material, and machine setup; perform trial runs and inspection to confirm tolerance for your application.

14. What is involved in installation and commissioning?

Installation typically requires a stable foundation or bench, proper electrical and hydraulic hookups per manufacturer specifications, correct alignment and leveling, and initial setup of dies and process parameters. Commissioning should be performed by trained technicians or with supplier support.

15. Are spare parts and after-sales support available?

Core components include bearings, gearboxes, motors, gears and pumps; replacement parts and after-sales support are normally available from the manufacturer or authorized dealers. Contact your supplier for warranty terms, spare parts lists and service agreements.
