The burr sits where no tool can reach.
Single-Robot Cell
1 · The challenge
Branched inside, not accessible from outside
Where this problem occurs
Predominantly aluminum die casting. All seven share the same characteristic: internal channels with cross-drilled holes and bore intersections. It is exactly at the crossing points that the burr forms which cannot be reached from outside.
Which burrs are meant
Four of them sit at or in bores. That is no coincidence, but the core of the task. There is no fixed standard burr type — what counts is the part geometry.
2 · Engineering considerations
Two factors decide before the machine
The burr root
Where the burr starts and how firmly it sits. The problem is not “the burr”, but its root.The accessibility of the deburring location
Whether a jet can reach it at all. That is the actual limit of the method, not the material.
Added to that are material, part geometry, size and weight, cycle time, residual contamination requirement, workpiece fixture and degree of automation.
The material is rarely the decisive factor. Aluminum, steel, stainless steel, brass, copper, zinc die casting and plastic can all be processed. Whether the method fits is decided by geometry, burr root and accessibility.
If the range of parts changes, that speaks for a movable jet guidance instead of fixed nozzles. If it stays the same, we check the more cost-effective stationary solution — even if that speaks against the more elaborate system.
3 · The machine concept
The robot cell with a single robot — our standard concept
- 01
The robot guides the nozzle
To every deburring location, including cross-drilled holes and internal channels. Standard is KUKA; we use ABB, FANUC and Yaskawa just as well if your factory standard specifies it. - 02
The nozzles are the tool of the method
We work with standard nozzles — and design and manufacture our own nozzle geometries when the application requires it. That is the difference between method development and system assembly. - 03
The water circuit is closed
Filtration is part of every system; we integrate more extensive water treatment depending on the project. - 04
Safety technology according to risk assessment
Safety fences, safety doors, light curtains — we design them according to risk assessment.
Where the concept is extended
- 01
Vision system
Detects position or result. - 02
Tool changer
Several nozzle tools in one cell, changed during the process. That way every burr location gets the suitable tool instead of one compromise for all. - 03
Barcode and DataMatrix systems
Component identification, deburring program per part, result per part written back. - 04
Automatic loading
Depending on the project. - 05
Line integration with further systems
Depending on the project. - 06
Rotary table
Depending on the project.
4 · The result — and its verification
Two results are verified
Process monitoring is qualitatively something different from the other four: it does not check the individual part but keeps the process within its window — the prerequisite for not having to check every part.
Where the limits are
When another solution fits
- 01
Dual-robot cell
When the cycle time cannot be reached with one robot. - 02
Stationary water jet deburring system
When always the same component runs in a fixed clamping position and fixed nozzle systems are enough. Then it is more cost-effective. - 03
Rotary indexing water jet deburring system (special solution)
When setup and clamping time are considerable in relation to the processing time. - 04
Industrial Parts Cleaning
When there is no burr to remove, but only cleaning to do.
Limits
When water jet deburring is not the right choice
Defined chamfers or radii are to be produced
The method removes burrs, it does not replace machining.Very firmly adhering or massive burrs are present
They have to be eliminated differently, by design or by manufacturing.The deburring location cannot be reached with any suitable nozzle concept
The method is not economically viable
For example at very small production volumes, or when a simpler deburring method is sufficient.Another method meets the requirements better
Technically or economically.
Tell us early what you have in mind. If another method is the better fit, we will say so.

Applications
Components on which this system design is decided
Each case sets out the design factors, the possible system concepts and the methods in detail — here you only find what it is about.
Hydraulic manifold
The channels are drilled, they intersect several times, and at every bore intersection a burr forms.
Valve block
The burr root sits at the bore intersection of two bores — no tool gets there, not because it would be too big, but because no path leads to it.
Components with heavy burrs
Casting flash and metal fines do not sit on one edge but spread out — and later they come loose by themselves.
None of these cases inevitably leads to the robot deburring cell. Which concept it becomes arises from the interplay of the design factors — the machine type is the result of the system design, not its starting point.
