Threading is a machining method used to make parts with thread shapes. Usually use thread lathe, thread milling machine, thread cutting tool and other equipment for thread machining. The process of threading involves cutting threads on a workpiece in order to fit them into other parts. Thread processing is usually used to manufacture bolts, nuts, screw conveyors, propellers, screw pumps and other parts.
Threading is a common machining method, which is used to make all kinds of threaded parts. There are many ways to thread machining. I will introduce several common thread machining methods below.
Advantages Of Threading
- Thread processing can improve the accuracy of parts.
Through thread processing, the thread line on the surface of parts can be more clear and regular, so as to improve the precision and quality of the thread. This is especially important for some high-precision mechanical parts, such as aircraft engines, automotive engines and precision instruments.
- Thread processing can improve the strength of parts.
Threading can increase the surface area of the part, thus improving the strength and tensile properties of the part. This is especially important for some mechanical parts that need to withstand high pressure and high load, such as the cylinder block and crankshaft of the automobile engine.
- Thread processing can also improve the tightness of parts.
The thread machining can make the thread line on the surface of the parts tighter, so as to improve the sealing performance of the parts. This is especially important for mechanical parts that need to be protected from leaks, such as pipes, valves and taps.
- Thread processing can also improve the beauty of parts.
Thread machining can make the thread line on the surface of parts more regular and beautiful, so as to improve the appearance quality of parts. This is especially important for some mechanical parts that need to be beautiful, such as car hubs and exhaust pipes.
Methods Of Threading
- Cutting method.
Cutting method is a traditional thread processing method, mainly through the lathe, milling machine and other mechanical equipment, using the tool to process the workpiece. The cutting method has the advantages of high precision and high processing efficiency, but it needs professional machining technology and equipment.
- Rolling method.
Rolling is a method of processing the workpiece through a roller or drum. Rolling method has the advantages of fast processing speed and good processing quality, but it needs professional rolling equipment and technology.
- Squeeze method.
Extrusion method is a method of extruding material into the shape of thread, which is mainly suitable for the machining of small threaded parts. Extrusion method has the advantages of fast processing speed and low processing cost, but it needs professional extrusion equipment and technology.
- Electric discharge machining method.
Edm is a method of machining by discharge, which is mainly used for thread machining of hard materials. The advantages of EDM are high precision and high processing efficiency, but it needs professional equipment and technology.
No matter what thread machining method is used, professional technology and equipment are needed to ensure processing quality and efficiency. Threading is an important machining technology, which provides necessary parts and equipment for various industries.
