As core precision components of automobile engines, engine blocks and cylinder heads feature complex structures, dense oil passages and numerous crossed blind holes. After machining, aluminum chips, iron scraps, oil contaminants and burrs are likely to remain on workpieces. Conventional cleaning equipment suffers from blind cleaning zones, incomplete deburring and inconsistent cleanliness, failing to meet strict mass‑production assembly standards of OEM manufacturers. To address these industry pain points, Sinobakr provides a dedicated CNC high‑pressure cleaning solution. Combining precise CNC control and high‑pressure water‑jet technology, it realizes one‑stop precision cleaning, deburring, degreasing and drying for engine blocks and cylinder heads, suitable for large‑scale production of passenger and commercial vehicle engine parts.
This solution adopts multi‑axis CNC linkage control system equipped with 3‑5‑axis precision servo drives. Cleaning trajectories for holes, inner cavities and threaded channels of engine blocks and cylinder heads can be pre‑programmed. The machine performs automatic positioning and targeted spraying during operation, overcoming the limitations of conventional fixed‑spray cleaning. Equipped with a variable‑frequency high‑pressure booster system, the cleaning pressure can reach up to 50 MPa with stepless adjustment to fit different materials and contamination conditions. Wear‑resistant gem nozzles support direct, angled and side spraying modes. High‑pressure jets penetrate deep into crossed holes, deep blind holes and narrow oil galleries to thoroughly remove embedded chips and machining burrs without damaging workpiece substrates, ensuring dimensional accuracy and surface integrity of components.
Compared with traditional ultrasonic cleaning and manual processes, the Sinobakr CNC high‑pressure cleaning solution delivers outstanding performance. Fully automatic operation covers six‑sided comprehensive washing, inner‑cavity flushing and high‑pressure air‑knife drying after workpiece clamping. Manual intervention is minimized to cut labor costs and human‑induced errors. For cast‑aluminum and cast‑iron engine parts, cleaning pressure, flow rate and cycle time can be flexibly tuned. It effectively solves common defects such as residual contaminants, loose burrs and oil adhesion, and consistently achieves the micro‑level high‑cleanliness acceptance criteria required by OEMs.
The solution balances high‑volume production performance with energy‑saving durability. An intelligent multi‑stage water circulation and filtration system enables water recycling, lowering water and consumable costs while complying with modern factory environmental requirements. Robust mechanical structure and heavy‑duty key components support 24‑hour non‑stop mass production with low failure rate and easy maintenance to improve line throughput. Modular design allows customized machine dimensions and axis configurations according to workpiece specifications and output demands, catering to both component workshops and large‑scale OEM plants.
Integrating accurate numerical control and high‑pressure water cleaning technology, Sinobakr’s dedicated solution resolves cleaning, deburring and degreasing challenges for critical engine components in one process. With stable cleaning quality, high productivity and low operation‑and‑maintenance costs, it safeguards mass‑production precision manufacturing, and helps customers boost product qualification rate and core market competitiveness.
