Normally, the round bar is either held stationary or rotated within the machine for the threading to be done by the cutting tool. The machine can manufacture any size of threaded bars depending upon the sizes of its cutting dies.

Bar thread machines can be categorized as follows:

• Manual Bar Threading Machine: The simplest form of the bar threading device, a manual thread machine, requires manual intervention to operate. By manually moving the round bar of the machine, threads can be cut. Training is necessary to understand how to thread bars manually precisely.
• Portable Bar Threading Machines: These are small and lightweight machines, making it easier to carry them from one location to another. Since they are not very big in size, threading small diameter bars is made easy. Power supply is not essential as they usually run on batteries.
• Automatic/ CNC Bar Threading Machine: These complex machines help thread bars automatically without human help. Using computer numerical control, the precise shape and dimensions of the threads can easily be achieved. Cutting, rotating, and holding the bar are all done automatically by the machine. This leaves threads with high precision and uniformity, which is better than manual threading.
• Hydraulic Bar Threading Machines: In this type of machine, hydraulic power is used to rotate the bar and hold it while cutting is done using the hydraulic system. The machine is used for heavy-duty threading applications. It can handle thicker diameter bars easily. Production is increased, and worker fatigue is decreased when hydraulic systems are used.
• Robotic Bar Threading Machines: This is an advanced machine that uses robotics technology to thread bars. Robotics can achieve threading operations much more quickly and precisely than traditional methods. Complex shapes and sizes of threads can be created with ease. Threaded bars manufactured by this machine are of very high quality.

Specifications and maintenance of round bar thread machine

• Speed: The speed of a round bar thread machine refers to the threading speed or rotational speed of the bar. It may be measured in revolutions per minute (RPM) or other units. The speed affects the machining efficiency and production capacity.
• Material compatibility: Material compatibility describes whether the machine can process different materials, such as steel, stainless steel, alloy, etc. It ensures that machines can meet various threading needs for round bars of different materials.
• Machine size: Machine size usually includes length, width, height, and weight. It determines the space occupied by the machine and its installation and placement requirements in the workshop.
• Operating system: The operating system of a round bar thread machine is the control method or system used to control the machine's operation. It may be a manual, semi-automatic or fully automatic operating system, which determines the operating mode and control accuracy of the machine.
• Accessory parts: The accessory parts of a round bar threading machine include chucks, clamps, threading heads, tool holders, etc. These parts are关键组件 for fixing, holding and machining the round bar, ensuring the stability and accuracy of the threading process.

Maintenance

• Clean: Regularly clean the machine to remove any dust, debris, or chips. This can help prevent clogging and overheating of the cooling system, ensuring the proper heat dissipation of the machine.
• Lubrication: Based on the instructions, apply lubricating oil to lubricate parts of the machine periodically. Lubricating oil can reduce friction and wear between moving parts, ensuring smooth operation and prolonging service life.
• Check Electrical System: Periodically check the electrical system of the machine, ensuring that the wiring is firm and reliable, avoiding electricity leakage or short circuits. Also, check the switch and control device, ensuring they are sensitive, and effective.
• Cooling System Maintenance: The machine's cooling system is crucial for heat dissipation. Regularly check the coolant level, supplement the coolant as required, and clean the cooling fan and radiator to ensure good cooling performance.
• Inspect Components: Periodically inspect the machine's critical components, including thread cutting tools, clamping devices, guide rails, etc. Ensure that these components are not worn, loose, or damaged so that they can maintain good working conditions.
• Adjust Machine: Adjust the threading machine periodically to maintain its threading accuracy and stability. This includes adjusting the position and tightness of clamping devices, the alignment of guide rails and threaded tools, etc.
• Pay attention to operating skills: Using a round bar thread machine properly is also essential for maintenance. Operators should pay attention to the correct operation, avoid overloading and over-speed threading, and reduce the machine's wear and damage.

Scenarios
