Deburring Systems
High-Speed CNC Hydro-Deburring System
The Accu-Jet® is a CNC controlled, hydro-deburring machine tool designed to flush and deburr precision metal or plastic parts. At the heart of the Accu-Jet® is a four-axis CNC controlled Cartesian gantry robot designed to pick a part from a feed conveyor, flush and deburr the machined surfaces using high-pressure water at high speed, and return the part to an exit conveyor. Cycle times can be greatly reduced with an optional fifth axis, allowing simultaneous processing of paired part features. High-pressure water up to 10,000 psi is recirculated and filtered to provide a closed-loop and environmentally friendly process. The Accu-Jet® is also available with optional feed and exit conveyors, a high-impact air blow-off, and vacuum drying to provide users with a complete integrated solution. Part manufacturers seeking flexibility, reliability and repeatability can rely on the Accu-Jet® to solve their production deburring requirements.
High-pressure water jets are used to effectively deburr and flush away unwanted burrs, chips and debris from narrow cavities, internal intersections, threads, and component edges of complex machined parts. Pressure acts as a means of accelerating the water to supersonic speeds and when water hits the part, it shears, pushes, and erodes away the burrs and removes debris in its path without damaging surface finishes or radius edges. This method is environmentally safe and does not use potentially damaging abrasives or solvents. Depending on the part geometry, a combination of specialized fixed and rotating nozzles are used to direct high-velocity water jets at specific areas or at the overall surface of a workpiece.
Hydro-deburring cannot remove all types of burrs. To test if highpressure deburring is the appropriate deburring method, see if the burr can be removed by pushing it with the lead of a 0.7 mechanical pencil without breaking the lead.
This technology produces consistent repeatable results at high production rates. Designed for total flexibility, this equipment can adapt to a variety of parts and be programmed for an infinite number of configurations.
Complex machined parts made of steel, ductile iron, aluminum and plastic such as fuel-injection components, ABS and traction control valves, transmission parts, pump housings, and pistons.
Precision Deburring
A CNC-controlled, gantry-style Cartesian robot manipulates workpieces precisely in close proximity to high-pressure water jets to effectively remove unwanted burrs, chips, and debris from narrow cavities, threads, and workpiece edges without damaging surface finishes or radius edges.
Ideal for Compact Precision Parts
Kemet can supply custom designed grippers to handle workpieces of up to 20 lbs in weight and 12 inches cubed in size.
Flexible and Reliable
With a CNC programmable robot, replaceable high-pressure deburr bolted tooling, and robot gripper, the Accu-Jet® allows process flexibility by adapting rapidly to various part configurations.
Integrated Part Loading
After passing through an identification station, workpieces are picked up from the feed conveyor by the gantry robot. The workpiece is then transported into the process cabinet for flushing and deburring.
Dual Manifold
An optional servo-controlled D axis can significantly reduce cycle times on workpieces with paired hole patterns. This feature permits paired holes to be flushed and deburred simultaneously, resulting in shorter cycle times.
Indexing Rotary Axis
The rotary indexing R axis changes the part orientation to expose different surfaces to the high-pressure deburring tools.
Rotary Deburring Probe
The rotary horizontal probe effectively deburrs and flushes away chips from threads, narrow cavities, and difficult-to-access intersections; all in one operation.

Six-Axis, Robotic Hydro-Deburring System
The RDB-700 is a robotic cleaning and deburring system designed to remove burrs, chips, and non-parent material from medium-sized, complex machined components. Using highpressure rotary water jets, an articulating robot is programmed to deburr all the machined holes, intersections, and difficult-to-access cavities of a workpiece mounted on a fixture. The lance nozzle precisely sprays a pressurized water-based solution to clean, flush, and deburr in a single operation. After cleaning, air is directed through the lance nozzle and the robot again passes through all machined areas, blowing excess solution away from the part.
The RDB-700 is a flexible system that combines reliability, precision, and quality – ideally suited to a machine shop environment.
