With the rapid development of the new energy vehicle industry, aluminum alloy die-cast housings such as motor housings, electronic control housings and gearbox housings feature increasingly complex structures packed with cross holes, blind holes, oil passages and interlayer cavities. Aluminum swarf, burrs, cutting fluid and release agent left after CNC machining have become critical pain points that restrict component cleanliness and vehicle reliability. Traditional manual deburring, brush washing, conventional spraying and ultrasonic cleaning struggle to reach dead corners inside cavities, often resulting in excessive residues, unstable quality and fluctuating yield rates. These methods can hardly meet the stringent VDA19 technical cleanliness requirements set by OEMs. Equipped with mature multi-axis CNC high-pressure water jet technology, the Bucker CNC high-pressure cleaning machine provides an integrated solution for deburring, swarf removal and precision cleaning of automotive die-cast housings. It is widely applied in mass production lines for new-energy three-electric housings and conventional automotive die castings.

The machine adopts a multi-axis servo CNC linkage control system, paired with rotatable and telescopic high-pressure water nozzles and fixture rotary tables. Following pre-programmed instructions, it accurately targets every hole and cavity of the workpiece. Multi-directional high-pressure water jets reach hidden areas inaccessible to conventional processes, including intersecting cross holes, deep blind holes, threaded holes and water cooling channels. Deburring and aluminum swarf flushing can be completed simultaneously in one clamping setup, eliminating workpiece transfer and secondary treatment. This greatly shortens cycle time and supports integration with automatic production lines. The high-pressure water jet is a non-contact physical cleaning process without abrasives or cutting tool contact. It will not scratch soft aluminum alloy surfaces or cause thermal deformation and dimensional deviation of workpieces. It balances cleaning performance and part accuracy while avoiding secondary contamination caused by grinding.

The Bucker high-pressure system supports wide pressure adjustment and is compatible with a range of wear-resistant nozzles. Jet parameters can be flexibly adjusted according to housing materials, hole sizes and burr levels to realize flexible production for die-cast housings of various specifications. The whole cleaning process is closed-loop and controllable. Cleaning fluid passes through multi-stage filtration, and contaminants are discharged with water in a timely manner. It delivers consistent cleaning results with minor batch-to-batch cleanliness variation, steadily complying with the automotive VDA19 cleanliness standard. It effectively reduces risks such as oil circuit blockage, seal failure and motor short circuit caused by particle residues, helping component manufacturers pass OEM cleanliness audits and sampling inspections smoothly.

For on-site line deployment, the equipment integrates auxiliary modules including automatic loading and unloading, waste liquid filtration and recovery, and air blow drying. It can connect to MES systems for traceability of processing and cleaning records, satisfying the quality traceability requirements for auto parts. Compared with similar imported equipment, Bucker offers local advantages in customized commissioning, after-sales maintenance and delivery lead time. It can quickly optimize fixtures and cleaning programs for different housing structures and cut customers’ production line modification costs.

As cleanliness thresholds keep rising in automotive manufacturing, the Bucker CNC high-pressure cleaning machine leverages core CNC water jet technology to solve the cleaning challenges of complex inner cavities of die-cast housings. It balances cleaning quality, production efficiency and manufacturing cost, serving as key cleaning equipment for stable and compliant mass production of new-energy automotive die-cast components.
