Shaft‑type parts are essential basic components for mechanical equipment, automotive transmission and engineering machinery, including straight shafts, stepped shafts, crankshafts, eccentric shafts and other variants. After turning, roll grinding, milling, heat treatment and surface treatment processes, cutting oil, grinding paste, metal chips and dust contaminants remain on shaft surfaces, keyways, oil holes and step gaps. Shaft workpieces feature numerous deep holes, annular grooves and dead corners at steps. Conventional high‑pressure spray cleaning and manual cleaning struggle to remove contaminants in concealed areas, often resulting in uneven cleaning, residual chips and water stains. Residual impurities may cause assembly wear and seal failure, directly undermining the operational stability of complete equipment and failing to meet high‑cleanliness requirements for mass‑produced precision parts. Targeting the processing characteristics and cleaning challenges of shaft workpieces, Barke presents a complete ultrasonic cleaning machine solution for shaft‑type parts.

This solution adopts an integrated process of main ultrasonic cleaning, multi‑stage rinsing and hot‑air drying, equipped with circulating filtration and oil‑water separation systems for mass‑production conditions of shaft parts. Relying on ultrasonic cavitation effect, powerful stripping action reaches hard‑to‑access spots such as oil holes, keyways and step gaps, efficiently removing oil stains, iron filings and processing residues. The uniform and gentle cleaning force prevents surface scratches and preserves dimensional accuracy as well as surface roughness, realizing precision damage‑free cleaning and meeting protection requirements for shafts of different materials.

The machine is fitted with a closed‑loop circulating filtration system to continuously filter metal abrasives from cleaning fluid. The oil‑water separation unit removes floating oil in a timely manner, slowing down cleaning fluid deterioration, cutting consumable replacement costs and effectively preventing secondary contamination, so as to guarantee stable cleaning performance during long‑time mass production. Process parameters can be flexibly adjusted according to workpiece dimensions and oil contamination levels. After ultrasonic cleaning, workpieces go through multi‑stage rinsing to eliminate residual detergent, followed by constant‑temperature hot‑air drying to thoroughly dry parts and remove water marks. Clean and dry shafts can be directly delivered to assembly or subsequent processing procedures.

Compatible with automatic loading and unloading mechanisms, the solution can be integrated into automated production lines to reduce manual operations and lower collision risks during handling. It delivers consistent cleaning results and controllable cleanliness, suitable for batch cleaning of long and short shafts of various specifications. Widely used in automotive components, motors, engineering machinery and precision transmission industries, it solves industrial pain points such as insufficient cleaning and unstable yield of shaft‑type parts, helping manufacturers improve cleaning quality, shorten production time and achieve quality improvement, cost reduction and efficiency enhancement.
