The Main Functions of CNC Pipe Threading Lathe

01/

Pipe Cutting: The machine is equipped with cutting tools that can accurately and precisely cut pipes to the desired length. This is the initial step in the threading process.

02/

Facing: The lathe can face the ends of the pipes, ensuring they are flat and perpendicular to the axis of the pipe. This is important for creating a proper thread.

03/

Chamfering: The machine can be programmed to chamfer the pipe ends, creating a beveled edge. Chamfering is often necessary for ease of threading and for achieving proper connections.

04/

Threading: The primary function of a CNC pipe threading lathe is, of course, threading pipes. The machine uses cutting tools to create external threads on the pipe's outer surface. The threading process can be customized based on the type of thread required, such as API threads or NPT (National Pipe Thread) threads.

05/

Thread Depth Control: The machine allows for precise control of the thread depth, ensuring that the threads meet the specified standards and requirements. This is crucial for proper engagement and sealing when connecting pipes.

06/

Taper Threading: Some CNC pipe threading lathes are capable of taper threading, allowing the creation of tapered threads on pipes for specific applications.

4 Tips for Choosing the Best CNC Pipe Threading Lathe

Consider The Size And Type Of Pipes You'll Be Working With
One of the most important factors to consider when choosing a CNC pipe threading lathe is the size and type of pipes you'll be working with. Different lathes are designed for different pipe diameters and thicknesses, so it's important to choose one that can handle the pipes you'll be using. Additionally, some lathes are designed for specific pipe materials, such as steel or plastic, so you'll need to make sure the one you choose is compatible with the material of your pipes.

Look For Quality Construction And Durability
Another important consideration when choosing a CNC pipe threading lathe is the quality of its construction and durability. Look for a lathe that is made with high-quality materials and is built to last. You don't want to invest in a lathe that will break down quickly or require frequent maintenance and repairs.

Pay Attention To The Machine's Features And Capabilities
The features and capabilities of a CNC pipe threading lathe can vary widely between different models. Some lathes may have more advanced programming options or automation capabilities, while others may be more basic. Consider your needs and the types of threads you'll be cutting, and look for a lathe that has the features and capabilities that will best suit your requirements.

Choose A Lathe From A Reputable Manufacturer
Finally, it's important to choose a CNC pipe threading lathe from a reputable manufacturer. Research different manufacturers and read reviews from other users to get an idea of the quality and reliability of their products. Choosing a lathe from a well-respected manufacturer can help ensure that you're investing in a high-quality machine that will provide reliable performance for years to come.

What to Do if the CNC Pipe Threading Lathe Loses Power

When a CNC pipe threading lathe is first put into use, it must return to the reference point when the system is restarted after a power failure. That is, when the axes are moved outside the non-interference zone by manual means, then make each axis return to the reference point. Otherwise, a collision accident may occur. Therefore, after machining every day, move the axes of the machine to a safe position. At this point, you will not need to return again after operating or powering off again.

Failure caused by external hardware operation is a common fault in CNC repair. Generally are due to detection switches, hydraulic systems, pneumatic systems, electrical actuators, mechanical devices caused by problems. Some of these faults can be found through the alarm message to find the cause of the fault. For general CNC system, there is a fault diagnosis function or information alarm. CNC pipe threading lathe maintenance personnel can use this information to narrow down the diagnosis. Some faults have alarm information, but it does not reflect the real cause of the fault. In this case, it is necessary to analyze and solve the problem according to the alarm information and the fault phenomenon.

For the repair of CNC pipe threading lathe, the important thing is to find the problem. Especially the external fault of CNC machine tool. Sometimes the diagnosis process is complicated, but once the problem is found, it is relatively simple to solve. The following two principles should be followed for external fault diagnosis. First of all, to master the working principle of the machine tool and action sequence. Second, to be able to use the PLC ladder. NC system status display function or off-board programmer to monitor the operating status of the PLC.

Precautions for Daily Maintenance of CNC Pipe Threading Lathe

When taking out a certain circuit board from the whole CNC pipe threading lathe, attention should be paid to recording its relative position and the connected cable number. For the fixed installation of the circuit board, the corresponding crimped parts and screws should also be taken down before and after for record. The dismantled crimp parts and screws should be placed in a special box to avoid loss, after assembly, the box should be used in its entirety, otherwise the assembly is not complete.

The soldering iron should be placed in front of a smooth hand and away from the maintenance circuit board. The tip of the soldering iron should be properly trimmed to accommodate the soldering of integrated circuits and to avoid touching other components when soldering.

Measurement of resistance between the lines, should be disconnected from the power supply, measurement of resistance should be red and black pencil interchangeable measurement twice, to the resistance value of the large as a reference value.

Most of the circuit board brush with solder resist film, so the measurement should find the corresponding solder as a test point, do not eradicate the solder film, some boards are all brushed with insulation, then only at the solder point with a blade to scrape the insulation layer.

Should not be arbitrarily cut off printed lines. Some maintenance personnel have certain home d maintenance experience and are used to cutting off lines to check, but most of the circuit boards on CNC equipment are double-sided metal hole boards or multilayer holeized boards, the printed lines are fine and dense, once cut off it is not easy to weld, and it is easy to cut adjacent lines when cutting lines, and then there are some points where the CNC pipe threading lathe does not make it detach from the lines when cutting a certain line, and it needs to cut several lines at the same time to do so.

Components should not be removed and replaced at will. Some maintenance personnel, without identifying the faulty components just by feeling that a component is bad, immediately dismantle and replace it. This has a high rate of misjudgment and a high rate of artificial damage to the dismantled components.

Dismantling components should be used to absorb tin and tin rope, do not take hard. The same pad should not be heated for a long time and repeated disassembly, so as not to damage the pad. Replace new devices, their pins should be properly treated, and acidic solder oil should not be used in soldering.

Record the switch on the line, jumper position, should not be arbitrarily changed. Pay attention to marking the components on each board when carrying out cross-checking of more than two poles, or when swapping components, so as to avoid confusion, resulting in even good boards not working.

Check the power supply configuration and type of the circuit board of the CNC pipe threading lathe, and according to the needs of the inspection, the power supply can be supplied separately or in full. Pay attention to the high voltage. Some boards are directly connected to high voltage or have a high voltage generator inside the board, which needs to be properly insulated, so special attention should be paid during operation.
