Boring:
It is a commonly used method for machining cylinder bore holes, which cuts the cylinder bore holes with a boring tool to achieve the required size and accuracy. The boring process is suitable for cylinder barrel machining of various materials, but the machining efficiency is relatively low and the technical requirements for workers are high.
Articulated hole:
It is a high-precision hole machining method used to improve the accuracy and surface quality of cylinder bore holes. The reaming process is suitable for small batch, high-precision cylinder barrel processing, but the processing cost is relatively high.
Rolling:
By using rolling tools to roll the inner hole of the cylinder, the surface quality and dimensional accuracy of the inner hole can be improved. The rolling process has high production efficiency and good processing quality, and is suitable for mass production of cylinder tubes.
Honing:
It is a high-precision hole machining method that uses a honing head to grind and polish the inner hole of the cylinder, achieving a mirror level surface quality. The honing process is suitable for high-precision and high surface quality cylinder barrel machining, but the machining cost is relatively high.
Cold drawing:
It is a processing method for stretching and reducing steel pipes through cold drawing molds, used for producing high-precision cold drawn pipes. Cold drawn pipes have the advantages of high inner and outer surface smoothness, high dimensional accuracy, and good mechanical properties, and are suitable for processing hydraulic and pneumatic cylinder barrels.

Carbon steel seamless pipe:
Carbon steel seamless pipe has the advantages of high strength, wear resistance, and easy processing, and is a commonly used material for hydraulic and pneumatic cylinder barrels. By precise cutting and chrome plating treatment, the durability and surface quality of seamless carbon steel pipes can be further improved.
Alloy steel:
Alloy steel has high strength and wear resistance, and is suitable for hydraulic and pneumatic cylinder barrels in harsh environments such as high pressure, high temperature, and high corrosiveness. Common alloy steel materials include 35CrMo, 42CrMo, etc. After quenching and tempering treatment, these materials have good comprehensive mechanical properties.
stainless steel:
Stainless steel has excellent corrosion resistance and is suitable for hydraulic and pneumatic cylinder barrels that require resistance to chemical corrosion. Stainless steel cylinder barrels are commonly used in industries such as food, medicine, and chemical.

Improve surface quality:
Through precision machining technology, the surface quality of the cylinder bore can be significantly improved, the friction coefficient can be reduced, and wear and leakage can be minimized. The surface roughness can reach Ra0.2 or below, achieving a mirror level processing effect.
Improve dimensional accuracy:
Precision machining technology can ensure the dimensional accuracy of the cylinder bore and meet the requirements of high-precision hydraulic and pneumatic systems. The roundness, straightness, and other positional tolerances of the cylinder barrel can also be strictly controlled.
Improve production efficiency:
Adopting efficient precision machining processes such as rolling and cold drawing can significantly improve production efficiency and reduce production costs. Meanwhile, precision machining techniques can also reduce subsequent processing steps and shorten production cycles.
Enhance product competitiveness:
High precision and high-quality hydraulic and pneumatic cylinder barrels can improve the performance and reliability of products, enhancing their market competitiveness. In the market, the demand for high-precision hydraulic and pneumatic cylinder barrels is increasing day by day, becoming an important way for enterprises to enhance their brand image and market share.
