Precision machining refers to the machining technology with a machining accuracy of 1 micron. It is realized by using precision machine tools, precision measuring tools and measuring instruments under strictly controlled environmental conditions, and the machining accuracy reaches and exceeds 0.1 micron. Precision machinery not only pursues the precision of processing and the limit of surface quality, but also includes the automation of product design, manufacturing and management. It can quickly respond to the needs of environmental trends, improve manufacturing rates, improve working conditions, and ensure product quality.

Precision machining processes are mainly fine turning, fine boring, fine milling, fine grinding and grinding.
① Fine turning and fine boring: Most of the precision light alloy (aluminum or magnesium alloy, etc.) parts of aircraft are processed by this technology. Processing on a high-precision lathe can achieve a precision of 1 micron and a surface unevenness with a height difference of less than 0.2 microns, and the coordinate accuracy can reach ±2 microns.
②Finish milling: used to process aluminum or beryllium alloy layout parts with complex shapes. Rely on the accuracy of the guide rail and spindle of the machine tool to obtain high mutual position accuracy.
③ fine grinding: used for processing shaft or hole parts. Most of these parts are made of hardened steel, which has very high hardness. Most high-precision grinding machine spindles use hydrostatic or hydrodynamic fluid bearings to ensure high stability. Fine grinding can achieve dimensional accuracy of 1 micron and out-of-roundness of 0.5 micron.
④ Grinding: Use the principle of mutual research of joint parts to select and process the irregular protruding parts on the processed surface. The abrasive particle diameter, cutting force and cutting heat can be accurately controlled, so it is a very high-precision machining technique in precision machining technology.

The process results of precision machining are:
① The geometric shape and mutual position accuracy of the parts reach the micron or arc second level;
② The boundary or characteristic size of the part is smaller than microns;
③ The microscopic roughness of the surface of the part (the balance height difference of the surface roughness) is less than 0.1 microns;
④ Mutual parts can meet the requirements of the joint force; ⑤ Some parts can also meet the exact mechanical or other physical characteristics requirements, such as the torsional stiffness of the torsion bar of the float gyroscope, the stiffness coefficient of the flexible element, etc.
Precision machining is also called CNC machining. It is mainly used in metal manufacturing, special equipment manufacturing, automobile manufacturing, railway, ship and other transportation equipment manufacturing, electrical machinery and equipment manufacturing, etc.

FAQ:

Q: Do you have stock in stock?
A: This product is a customized product, the pattern and price are only for the buyer's reference.

Q: Order process
A: We can quote according to the drawings or samples of the products to be produced by the buyer, and provide specifications, materials, production requirements, etc. The specific unit price will be quoted according to the size, quantity, material and thickness, process complexity, production requirements, etc.

Q: Delivery time
A: Different materials and styles have different production processes and different time. Please consult customer service for details.

Q: About transportation
A: Because the customized products have different specifications, varieties, materials, etc., the freight cannot be accurately calculated, so the quotation does not include the freight. If you need a quote including shipping, please contact us. thanks!
