Lathe thread rolling machine

Types of Lathe Thread Rolling Machines

There are four main types of machines that can perform the function of a lathe thread rolling machine:

• Cylindrical Die Rolling Machines:

The cylindrical thread rolling machine uses two dies to create a thread on the workpiece. One die is stationary, while the other is movable. The workpiece is placed between the two dies, and pressure is applied to the movable die, which causes the thread to deform into the workpiece. Cylindrical die rolling machines are versatile in their ability to create threads on various workpiece shapes, including cylindrical, conical, and spherical parts.

• Flat Die Rolling Machines:

Flat die thread rolling machines use two flat dies to form the thread on the workpiece. As with the cylindrical die machine, one die is stationary, while the other applies pressure to deform the thread into the workpiece. Flat die rolling machines are well-suited for creating external threads on cylindrical workpieces. They are also used for rolling threads on screws, bolts, and other fasteners.

• Planetary Die Rolling Machines:

Planetary thread rolling machines have multiple dies arranged in a circular pattern around the workpiece. As the workpiece rotates, the dies are pushed inward to create the thread. Planetary threading machines are suitable for high-volume production of threaded parts. The machines are known for their high speed and efficiency. They can simultaneously form multiple threads on a workpiece.

• Axial Rolling Machines:

The axial thread rolling machine is also known as the radial thread rolling machine. This machine forms threads by moving the workpiece axially against a stationary die. It functions similarly to a lathe machine, but instead of cutting the thread, it deforms the material to form the thread. Axial rolling machines are commonly used to produce external and internal threads on workpieces. They are ideal for creating threads on cylindrical parts like shafts, rods, and pipes.

Specifications and Maintenance

• Specifications

The specifications of the lathe thread rolling machine vary depending on the model and type, such as external or internal thread rollers. Here are the specifications of the machine under different aspects.

Rolling speed and force: The process of rolling threads on a workpiece involves the application of force and movement. The rolling speed and the force with which the rollers are pushed into the workpiece are vital to the quality of the thread produced. The force and speed can be adjusted in the machine. The rolling force is measured in tons, and the speed is measured in revolutions per minute (RPM). The rolling force capacity of the machine can range from several tons to tens of tons, depending on the model. The rolling speed of the machine can also vary, typically ranging from 30 to 100 RPM.

Thread size capacity: The sizes of threads that can be rolled with the machine are based on the diameter and pitch of the threads. The machine can be used to create threads with various dimensions, ranging from micro-sized threads to larger threads. The maximum diameter of the workpiece that can be accommodated by the machine determines the maximum size of the threads that can be rolled. The thread size capacity of the machine is usually expressed in terms of the maximum diameter and pitch it can handle.

Power rating: The power rating of the machine's motor determines the strength of the machine. The power of the motor is the force behind the rollers. The power rating of the machine can vary depending on the model. It is usually measured in watts or horsepower. The rating can range from several hundred to several thousand watts. Higher power ratings indicate greater motor strength and the ability to handle larger workpieces and higher rolling forces.

Precision and repeatability: The precision and repeatability of the machine is important when trying to achieve consistent thread quality. The precision refers to the tight tolerances and accuracy of the machine's components, while repeatability describes its ability to consistently produce the same results. The precision and repeatability of the machine are achieved through features like precise controls, rigid construction, and high-quality components. The machine can help in making threads with high accuracy and repeatability.

Durability and build quality: The machine is usually made of high-quality materials. The machine is designed to withstand heavy-duty use and provide long-lasting performance. The heavy-duty construction of the machine ensures that it can withstand the forces and stresses of the thread rolling process. The durability and build quality of the machine make it suitable for use in demanding industrial applications.

• Maintenance

Proper maintenance is essential for the optimal performance and longevity of the lathe thread rolling machine. Here are some maintenance tips.

Cleaning: Regularly clean the machine to remove chips, debris, and oil buildup. This prevents contamination and friction, which can lead to damage.

Lubrication: Apply lubricant to the moving parts and surfaces to ensure smooth operation and reduce wear. Lubrication is important in preventing overheating and premature wear of components.

Inspection: Periodically inspect the machine for signs of damage, wear, or loose components. Check the rollers, guides, and drive systems to ensure they are properly aligned and functioning. Look at the electrical connections and controls for any loose parts.

Adjustments: Follow the manufacturer's instructions to make the necessary adjustments to the thread rolling machine. This may include adjusting the pressure and speed of the rolling process and making changes to the machine's settings.

Safety: When performing maintenance tasks, it is important to follow all safety precautions. Disconnect the power and wait for the machine to cool down before performing maintenance. Wear proper protective equipment to prevent accidents.

Training: Ensure that people who are responsible for maintenance have the proper training and skills. Training helps them understand the machine's structure and key components. This will enable them to properly maintain the machine and identify potential issues.
