(1) Ultrasonic Cleaning Machine
Working principle: Utilize the "cavitation effect" generated by ultrasonic waves in the cleaning solution to form the impact force when tiny bubbles burst, peeling off stubborn stains (such as polishing wax, sintered carbides) on the surface of parts.
Advantages: Suitable for parts with complex structures (such as blind holes, deep grooves, multi - hole parts), the cleaning accuracy can reach 5 - 10μm, with a high degree of automation and can be integrated into the production line.
Typical applications: Cleaning of precision components such as electronic components (such as PCB boards), watch parts, fuel injectors, etc.
(2) Spray Cleaning Machine
Working principle: Spray the heated cleaning solution (such as alkaline solution, water - based cleaning agent) onto the surface of parts through high - pressure nozzles, and use mechanical impact force and chemical action to remove oil stains and chips.
Advantages: High cleaning efficiency (single - batch processing time is 5 - 15 minutes), suitable for medium - to - large - sized parts (such as automotive engine blocks, box - type parts), and can be equipped with a rotating worktable to achieve all - round cleaning.
Technical parameters: The spray pressure is usually 0.3 - 1MPa, the temperature control range is 40 - 80℃, and a filtration system (with an accuracy of 50 - 100μm) is required to prevent nozzle blockage.
(3) Drum Cleaning Machine
Working principle: Parts and cleaning media (such as steel balls, plastic particles) rub against each other in a rotating drum, and combined with a cleaning agent to remove surface burrs and oxide scale, having both deburring and cleaning functions.
Advantages: Suitable for small - to - medium - sized parts produced in batches (such as standard parts, die - cast parts), which can reduce the cost of manual deburring, but may cause scratches on the surface of precision parts.
(4) Vapor - phase Cleaning Machine
Working principle: Utilize the vapor - condensation characteristics of solvents such as halogenated hydrocarbons, and dissolve the grease on the surface of parts through steam condensate. It is suitable for high - precision and easily corroded parts (such as optical lenses, semiconductor devices).
Advantages: No liquid residue, and parts can be directly assembled after cleaning. However, attention should be paid to the environmental friendliness of the solvent (such as replacing ODS substances with hydrocarbon solvents).
