What are precision turning parts?

The precision turning parts are a kind of parts made by the turning machine. It uses the rotation movement of the workpiece and the straight line or curve motion of the tool to change the shape and size of the parts, and machine the parts according to the requirements of drawing.

What are the characteristics and advantages of precision turning parts?

The accuracy of precision turning parts is IT11-IT7, some can reach IT6, and the roughness RA on the surface can reach 12.5-08um.There are many types of precision turning parts: shaft parts, cylindrical parts, discs, and set parts. It is famous for maintaining the thermal stability. Reasonable turning systems can reduce or even eliminate the grinding process and the high tool costs. A reasonable turning process can obtain the surface smoothness of only 0.0028mm, 0.0002mm circularity, and ± 0.005mm tolerance for diameter.

The differences between precision turning parts and traditional turning parts are the following:

  1. Different working methods

The CNC turning process adopts a digital signal control system. It can automatically adjust the parameters of the machine, such as speed, and cutting volume, through the preset program to achieve automation of processing. Ordinary turning relies on the manual operation of workers, with certain limitations.

  1. Different control methods

The control system of CNC turning can use digital input instructions to achieve automatic programming of the machine. It is a simple and convenient operation and can control the processing accuracy. Ordinary precision turning relies on workers’ experience and skills, which makes it relatively easy to cause errors.

  1. Different processing accuracy

CNC turning can meet the high-precision requirements through the program preset. It has high processing accuracy and stability and can adapt to the processing of various materials. The processing accuracy of ordinary precision turning is restricted by workers’ experience and operating skills, which cannot ensure high-precision processing and a narrow scope of application.

  1. Different production efficiency

CNC turning to adopt advanced processing methods of automation, which can complete a single, small, medium -batch or even large-scale production, and the production efficiency can be greatly improved. Because of the relatively slow operation, ordinary turning is suitable for the production of small batches or individual parts.

In actual production, CNC turning has the advantages of process standardization, program automation, high processing accuracy, and high efficiency.

What are the applications of precision turning parts?

  1. Machinery manufacturing: precision turning parts are used to in the industry equipment, such as various shafts, discs, sets, and other parts of rotating symmetry.
  2. In the aerospace industry:  turning processing technology is used to make components such as engines, propellers, flight control systems, and wings. Parts in the aerospace industry often require high precision, high strength, and lightweight, and precision turning parts can meet these requirements.
  3. The automobile industry: turning processing is widely used in the production of automotive engines and chassis support components. Parts such as shafts, bearings, crankshafts, and camshafts. The automotive industry usually requires high-precision and high-quality surface treatment, precison turning parts can meet these strict requirements.
