Cnc Turning Parts For Machining

CNC turning machining parts mainly refers to various parts processed by CNC lathes.

1, Parts with high precision requirements: The accuracy of precision CNC machining parts includes size, shape, position and surface, etc., and surface accuracy refers to roughness. CNC lathes have good rigidity, high manufacturing and tool accuracy, can be manually and automatically compensated, can process parts with high dimensional accuracy, and some can be replaced by grinding. Its movement depends on high-precision calculation and drive, and can process parts with high shape accuracy. One clamping to complete the content, can improve the position accuracy, stable quality. With constant linear speed cutting function, it can process parts with small and uniform surface roughness, suitable for parts with different roughness requirements.

2, parts with small surface roughness value: CNC lathe used in precision CNC machining has excellent constant linear speed cutting function, which can efficiently process parts with minimal surface roughness value and uniformity. This is because in the specific case where the material, the finishing margin and the tool have been determined, the roughness of the part surface mainly depends on the two key factors of feed rate and cutting speed. When these two parameters can be accurately controlled and optimized, CNC lathes can give full play to their advantages, thereby producing parts that meet the requirements of high precision and excellent surface quality.

3. Parts with complex surface outline: Because the CNC lathes used in precision CNC machining have excellent linear and circular interpolation functions (it is worth mentioning that some CNC lathes even have some non-circular curve interpolation functions), because of this, it can be extremely good at turning extremely complex rotary parts composed of arbitrary straight lines and all kinds of plane curves. Moreover, it also includes those list curves that have been processed by fitting calculations and cannot be accurately described by equations. This powerful processing capability makes CNC lathes play a vital role in the field of precision manufacturing, providing a strong technical support for the production of high-precision, high-quality complex parts.

Machine parts Machining is a complex process that involves several key steps and technologies.

The following is the main content of mechanical parts processing:

Selection of raw materials and quality testing: the selection and quality of raw materials directly affect the molding of finished parts, generally choose metal materials, such as steel, aluminum and so on. In order to ensure the quality of raw materials, raw materials need to be tested to ensure that the composition, strength, hardness, appearance and so on meet the requirements.

Processing technology design: processing technology is the core, its quality directly affects the product yield and quality. Processing process design needs to be designed according to different requirements such as the shape, size, material and customer needs of the parts, determine the processing sequence, parameters, tools, fixtures, etc., and reasonably plan the processing flow.

Numerical control machining technology: Numerical control machining technology has become one of the important technologies in the field of mechanical parts processing in recent years. Compared with the traditional ordinary machine tool machining, CNC machining has the advantages of high precision, high efficiency and low error. In NC machining, the automatic machining control is carried out by computer, and the machining operation of workpiece is realized by writing program. At the same time, CNC machining can also achieve a variety of forms of processing, including milling, turning, drilling and so on.

Measurement technology: Measurement technology is a crucial part of the machining of mechanical parts. The precision and quality of the machining can be checked through the measuring instrument, and the machining process can be controlled and adjusted. In the machining of mechanical parts, the measuring equipment used includes micrometer, height meter, quadratic element, etc. With the continuous development of science and technology, high-precision measuring equipment such as the new coordinate measuring machine is also used in the machining of mechanical parts, which improves the accuracy and efficiency of the machined parts.

Quality inspection after processing: After the processing is completed, the quality of the parts needs to be tested. Through precision inspection equipment, check the size, shape, surface finish, material composition and other parameters of the parts. If it does not meet the requirements, it needs to be re-processed or adjusted.

Follow-up treatment of the parts: After processing, the parts also need to undergo follow-up treatment. Common follow-up treatment are surface treatment, rust prevention treatment, cutting processing and so on. They can make parts more beautiful, improve corrosion resistance and mechanical properties.
