Chamber cleaning system
Changing range of parts, small to medium production volumes, several process steps in one closed chamber.
Here it is not enough for the result to be right. It has to be verified.
Aerospace
Residual contamination, surface quality, process reliability, working to the requirements specification, complete documentation — that is the task. The system is its result.
1 · What is different in this industry
Not the requirement on the part — the one on the verification
The technical requirements for cleanliness and deburring resemble those of the automotive industry. What differs is how much of it has to be verified, and how. In series production a system is accepted and runs. Here it is additionally required that every step remains traceable.
Residual contamination
The permissible amount and size of particles in the component.Surface quality
The process must not change the surface.Process reliability
Not one good result, but every one.Working to the requirements specification
The requirement is fixed beforehand and is tested against.Documentation
All of it traceable, even years later.
The last two are the actual difference. Residual contamination and process reliability are demanded by the automotive industry as well. Requirements specification and documentation shift the task from the result to the way there — and with it to the working method of the system builder.
2 · Which components are involved
What counts is not the industry, but the component
Internally branched housings, channels with cross-drilled holes, blind holes and bore intersections pose the same task — whether the part later works in a gearbox or in an aero engine.
Documented component class
Control components
Materials: we process aluminum, steel, stainless steel, brass, copper, zinc die casting and plastics alike. There is no limit at the material.
3 · How we verify the result
Two results, five test methods
Not one thing is tested, but two: residual burr — is the burr gone? And residual contamination — is the part clean?
Visual inspection
Burr visibly present or not.Camera-based inspection
The same, automated, reproducible, in the cycle.Residual burr inspection
The deburring result itself.Residual contamination analysis
The cleanliness, where required per VDA 19 / ISO 16232.Process monitoring
The running process, not the individual part — it keeps the process within its window and is thus the prerequisite for not having to test every part.
Process monitoring is qualitatively something different from the other four. In an industry that demands process reliability, that is the decisive point. The residual contamination analysis is carried out by an independent, accredited test laboratory — not by us. In an industry that demands verification, that is not a disadvantage but the point: the figure our release depends on comes from a third party that is not bound by our instructions.
What „working to the requirements specification“ means with us in practice
The requirement is not tested at the end, but released stage by stage.
Release chain
- 01Requirements specificationThe requirement is fixed beforehand.
- 02Design releaseEvery design stage is released by you.
- 03Factory acceptance test (FAT)Internal acceptance before delivery.
- 04Site acceptance test (SAT)Second acceptance after installation at your site.
If the agreed values are not reached, we do not release the system. And the documentation stays where the system stands: traceability down to the individual component is possible depending on the project — via barcode or DataMatrix recognition, the processing program can be selected per part and the result written back per part.
4 · Which solutions answer this
Only now the system
Requirement and verification chain are fixed — the concept follows from them.
4.1 · Cleaning
Immersion and spray-immersion cleaning system
When the component has to be fully immersed or outer surfaces and cavities have to be treated at the same time.
Continuous and rotary indexing cleaning systems
Where high production volumes arise in short cycles and the range of parts is fixed at the planning stage.
We add ultrasonic cleaning with immersion and flooding processes, vacuum drying for very high drying requirements. The water quality is a design factor of its own — up to demineralized water when the residual contamination requirement and the downstream process demand it. Where needed, we design the water treatment as well.
4.2 · Deburring
The high-pressure water jet reaches bores and internal channels that mechanical tools cannot — reproducibly and in the cycle, which tips the balance where process reliability is required.
We design the pressure to the task, not from a catalog — and we avoid unnecessarily high pressure, because it damages components without removing the burr any better. Where surface quality is required, that is not a side remark but the core of the system design.
4.3 · Automating
Loading and unloading, linking, buffering: with robot, handling and material flow and conveying technology from our own design engineering. Here, automation is at the same time a contribution to process reliability — an automated sequence is the reproducible one.
5 · Where we advise against it
The most important point on this page is in the limits, not in the services
Where a defined chamfer or a radius is required, the water jet is the wrong process. It removes the burr, it does not shape the edge. Where surface quality is required, that is the first question to be clarified — before any system design.
Very firmly adhering or massive burrs
Cannot be removed cost-effectively with the water jet.Deburring location not reachable with any nozzle concept
Then we say so — and not only at acceptance.Unrealistically low residual contamination requirements
We raise them before the quotation. In an industry that works to the requirements specification, that is exactly where it is decided whether a project holds.Spray shadow when spraying
With complex geometries and many blind holes, immersion and flooding deliver the better results.
6 · Where we stand in aerospace
The third industry with all three areas of work
Alongside the automotive industry and machinery manufacturing, this is the third industry in which all three areas of work are backed by delivered systems.

Questions and answers
Frequently asked questions from aerospace
How are cleaning quality and technical cleanliness verified and documented for aerospace components?
Not by looking. What counts as clean is written beforehand in the requirements specification — and that is what is tested against, not a general yardstick. Depending on the requirement, five methods come into question: visual inspection, camera-based inspection, residual burr inspection, residual contamination analysis and process monitoring. The first four test the part, the fifth the running process — it keeps the process within its window and is thus the prerequisite for not having to test every part. The residual contamination analysis is carried out by an independent, accredited test laboratory, not by us: the figure our release depends on comes from a third party that is not bound by our instructions. Verification is done stage by stage instead of at the end — requirements specification, design release, factory acceptance test, site acceptance test after installation at your site. If the agreed values are not reached, we do not release the system. Which methods and which depth of documentation it becomes in the individual case depends on the requirements specification and your specifications.
Applications
One task from this industry
One worked-out task is assigned to aerospace. What tips the balance in it is on its own page.
Every case lists the design factors, the possible system concepts and the processes in detail — here is only what it is about.
High technical cleanliness
It is not cleanliness itself that is difficult, but its verification: a component that is clean, but not demonstrably clean, cannot be used in a manufacturing operation with a verification requirement.
The assignment classifies — it claims no project. And it decides nothing about the system: which concept a task needs arises from the interplay of the design factors, not from the industry.
