The turbine housing serves as a core component of an automotive turbocharging system. It features an intricate internal structure with profiled flow passages, cross holes, blind holes and narrow gaps. After casting and machining, residues such as aluminum chips, burrs, cutting fluid, oil contaminants and release agents tend to remain inside. Even tiny residues may undermine turbine dynamic balance and airflow stability, which can directly trigger abnormal noise, shortened service life and unstable power output. For this reason, precision cleaning and deburring of turbine housings constitute a critical procedure in auto parts manufacturing. Conventional immersion cleaning, ultrasonic cleaning and simple high-pressure spraying struggle to reach deep inner cavities and deliver satisfactory results on root burrs of cross holes. Consistency of cleanliness is hard to stabilize to meet OEM specifications. The Sinobakr CNC high-pressure cleaning machine for automotive turbine housings is specially developed to address such pain points.

Equipped with a proven multi-axis linkage CNC system, this Sinobakr machine differs from ordinary fixed-point spray cleaning equipment. The high-pressure water jet nozzle moves along multi-dimensional paths under programmed control. It follows the contours of complex cavities including turbine volute passages, exhaust holes, cooling cross holes and mounting holes for targeted high-pressure water jet impact. The jet penetrates hidden areas inaccessible to conventional cleaning methods, efficiently stripping off machined aluminum chips and turned-over burrs while flushing cutting oil and polishing residues adhering to cavity walls. The non-contact water jet deburring process avoids scratching precision surfaces of turbine housings and eliminates mechanical stress from cutting tools, preventing deformation of thin-walled housings and making it suitable for vulnerable aluminum-alloy turbine housings.

The machine integrates a one-stop workflow. Once the workpiece is loaded and positioned, it automatically completes the whole process of high-pressure water jet deburring, circulating flushing, rinsing, air blow-off and hot-air drying. No repeated workpiece transfer or fixture replacement is required, which greatly reduces manual operation and the risk of secondary contamination. It is fitted with a precision filtration and circulation system with multi-stage filters to intercept stripped aluminum impurities and maintain stable cleaning water quality, extending the service life of high-pressure pumps and nozzles. Cleaning parameters, motion paths, pressure and duration can be saved and recalled on the CNC interface. Corresponding programs can be retrieved quickly during product changeover to accommodate different turbine housing models, supporting flexible mixed production of multiple variants on one line.

In terms of quality control, the complete process complies with cleanliness requirements of major domestic automotive OEMs. The size and weight of residual particles on cleaned workpieces can meet standards consistently, with traceable cleaning records. It caters to quality management demands of automated production lines for turbo parts of both new-energy and fuel vehicles. The machine is fully sealed for splash protection in high-pressure zones, with centralized waste liquid collection. Its noise level and safety interlocks conform to industrial standards, enabling stable 24-hour continuous production on the shop floor.

Leveraging the advantages of CNC high-pressure water jet technology, the Sinobakr turbine housing CNC high-pressure cleaning machine solves industry challenges including difficult deburring on cross holes in complex cavities and unstable cleanliness. It replaces inefficient traditional cleaning solutions and balances cleaning quality, productivity and yield rate. As a preferred automated facility for precision deburring, high-cleanliness washing and drying after finish machining of turbine housings, it is widely deployed in turbo component factories and supporting production lines for automotive OEM parts, facilitating high-quality manufacturing of auto components.
