Description

TECHNICAL FIELD

[0001] The application relates to the technical field of rotors, in particular to a vane rotor device and a high-precision frozen trimming machine. BACKGROUND

[0002] The high-precision frozen trimming machine is a device used for trimming and processing the surface of a material. It is commonly used in the fields of micro-machining, fine trimming and precision part manufacturing. The working principle of the machine is to use freezing technology and high-speed projectiles to process the surface of the material. The machine rapidly cools the surface of the material by using high-speed injection of frozen gas (such as liquid nitrogen), causing thermal stress and thermal contraction of the surface. Then, high-speed projectiles (such as metal particles, sand or ceramic microbeads) are fired to remove or trim the defects, oxides or other contaminants on the surface of the material. The high-speed projectiles cause surface deformation, peeling or trimming during impact, and can remove tiny impurities and fine defects, thereby improving the quality and precision of the surface.
