Are you struggling with burrs in areas that are difficult to process using conventional tools, such as small gears, cross holes, and deep holes? Manual deburring often results in inconsistent quality, high operator workload, and reliance on skilled workers, making it difficult to establish a stable mass-production process. The “JDM” water jet deburring machine from Sugino Machine (Thailand) solves these challenges by utilizing high-pressure water up to 70 MPa. It removes burrs from complex-shaped parts without contact while simultaneously achieving stable quality and process automation. In this article, we introduce the key features and benefits of the “JDM”.

Water Jet Technology Ideal for Removing Burrs in Deep Holes and Cross Holes

For deburring areas that are difficult to access with conventional cutting tools—such as small gears and cross holes—automated water jet processing is highly effective. In particular, the new “JDM” combines high-pressure performance with specialized design to automate and reduce labor in deburring processes that previously required manual work.

Q. What is Water Jet Deburring?
Water jet deburring is a deburring method that removes burrs using the impact force generated when high-pressure water sprayed from a nozzle strikes the burr.

Q. Why is it suitable for deburring?
Even when there are minute level differences, uneven surfaces, or dimensional variations, high-pressure water can uniformly affect the target area within its effective range, making it ideal for deburring complex-shaped parts. In addition, it suppresses excessive material removal, allowing edge shapes to be maintained while reducing quality variations and achieving stable, consistent finishing quality.

▲ Unlike creating “C” (chamfer) or “R” (radius) shapes, water jet deburring selectively removes only burrs while maintaining the edge.

Q. Why is it effective for automation?
Deburring complex shapes and deep holes is highly difficult with manual work and also challenging to automate through conventional machining. Water jets maintain impact force even at a distance, making them highly effective for automating deburring processes and reducing labor requirements in such areas.

Features of the Dedicated Deburring Machine “JDM”

“JDM” is a specialized machine developed specifically for deburring small workpieces. Compared to conventional models, it increases water jet pressure to improve deburring performance. In addition, the newly developed dual-nozzle system enables a more compact machine design.

【Main Features】
・ High-Pressure Water Jet up to 70 MPa
By increasing pressure beyond conventional models (approx. 50 MPa), deburring performance is significantly improved. This expands the range of burr types and materials that can be processed and enables automation and labor reduction for deburring processes that previously relied on manual work.

▲ Capable of removing burrs from cross holes and gear sections.
