Swiss-quality deburring and polishing
Stäheli AG is the Swiss market leader in deburring and polishing complex workpieces with its unique abrasive flow machining (AFM) process. Our viscous grinding compound reaches internal parts of your component that are difficult to access. Our service: perfect deburring, internal surface polishing and clean borehole chamfering. Our machining methods are ideal for a huge variety of components from every industry, including medical technology, sensor technology, chemical pharmaceuticals, mechanical engineering and tool manufacturing.
Our services in detail
In the videos below, we go through the details of the individual machining steps:
1. Custom clamping device
For each new product, we manufacture a custom-made clamping device for deburring the workpieces. The clamping device ensures the components are fixed securely on the one hand while also determining the flow of the grinding paste. That lets you machine one specific part while protecting the others. The clamping device is cleaned, repaired if necessary and stored with us in preparation for future tasks.
2. Mixing the grinding medium
Deburring with abrasive flow machining involves pressing a viscous grinding compound through the workpiece. We specifically adapt the properties of this grinding compound to the component and machining process with our own mixtures and formulations.
3. Deburring with viscous grinding paste
The viscous grinding paste can be used to deburr, chamfer or polish difficult-to-reach internal component parts. The grinding paste passes through the part to be machined under high pressure. The abrasive flow machining process deburrs high-precision workpieces to perfection.
4. Cleaning parts
To ensure precision parts or medical engineering parts can be further processed by the customer after deburring, it is important to clean them with approved cleaning processes.
5. Our quality controls
Following deburring and polishing, the workpiece machining is checked and inspected. Our services range from visual inspections to surface quality measurement reports for each workpiece, depending on the customer’s requirements.
