Complex structures with numerous dead corners: Hidden areas such as flexspline tooth grooves, micro‑bearing clearances, cycloid wheel micro‑holes, and tiny slits easily trap micro‑chips and polishing residues, which cannot be completely removed by conventional cleaning methods.
Ultra‑high precision requirements: Parts feature micron‑level precision tolerances. Water‑based cleaning tends to leave water stains, water spots and whitening oxidation. Residual moisture causes failure of subsequent grease lubrication and part corrosion.
Stringent residue standards: No visible oil films, particles or dust contaminants are allowed. Parts must meet dust‑free, oil‑free and water‑free assembly requirements for precision transmission components.
Fragile materials prone to damage: Alloy steel, stainless steel, copper alloys, thin‑walled flexsplines and other components are sensitive to acids, alkalis and high temperatures, susceptible to deformation, scratches and oxidative discoloration.
Difficult mass‑production consistency: Manual cleaning and simple‑equipment cleaning result in large batch‑to‑batch variations, failing to meet automated mass‑production assembly demands for humanoid robots.

1. Complete Process Flow
2. Analysis of Core Process Advantages
Vacuum negative‑pressure ultrasonic degreasing: Air is removed from solvents in a sealed vacuum environment, significantly enhancing the penetration of ultrasonic cavitation. It penetrates deep into tooth grooves, micro‑holes and slits to rapidly remove stubborn cutting oil, polishing paste and heavy oil deposits, solving dead‑corner residue issues.
Multi‑stage fine rinsing and purification: Gradient‑clean hydrocarbon solvents are adopted for multi‑stage rinsing to gradually wash away micro‑particles, polishing powder and metal debris, eliminating secondary contamination and ensuring high surface cleanliness.
Low‑temperature sealed full‑process treatment: Cleaning is carried out at ambient and low temperatures without high‑temperature damage, effectively protecting the dimensional accuracy of thin‑walled flexsplines and precision gears and preventing deformation, oxidation, discoloration and corrosion.
Water‑free vacuum flash drying: Instant drying under low pressure with no water involved, leaving no watermarks, residual liquid or surface haze, perfectly matching subsequent oil injection and assembly procedures for precision reducer components.
Closed‑loop solvent regeneration and recycling: The equipment is equipped with an in‑house vacuum distillation regeneration system for real‑time filtration, purification and recycling of contaminated solvents, achieving a solvent recovery rate of ≥95% and greatly reducing mass‑production consumable costs.
