What aspects come to mind when you think about brake disc coating?
That's right, there are a lot. Be it the selection of the powder, the powder feeder, the beam source, the optics, the nozzle, the powder feed flow and layer thickness measuring system, the performance and process online monitoring system and much more.
All of these issues have a direct or indirect impact on the quality of brake disc coatings and their costs.
Most manufacturers of laser systems for coating brake discs to comply with the new Euro7 standard commit to certain process components in order to position their systems on the market.
The Swabian special machine manufacturer Maschinenfabrik Arnold is going its own way here. Since 1985, the family-run medium-sized company has been supplying customer-specific laser systems worldwide and, if requested, lets its customers, who often have their own experience and process-technical knowledge of their components, decide on the component selection and system design.
This flexibility now also makes a difference in the development of systems for coating brake discs.
Arnold has developed a modular system that meets many requirements.
Let’s start with the system design.
The development of a layer technology requires an extremely flexible, easily accessible machine.
For this, Arnold has the BrakeMini
A manually loaded cell with all setting options and the adaptability of different beam sources and optics. This cell has been used successfully for a long time by development partner Oerlikon Metco in Wohlen (Switzerland).
The BrakeRotate was developed especially for large-scale production.
The BrakeRotate is characterized by a fast turntable for part changes during production, NC axes for all process-relevant movements, the possibility of integrating online monitoring systems, powder flow measurement systems, power measurement, layer thickness measurement. As a special treat, there are variants in the clamping technology that make it possible to machine both steel and aluminum brake disks. Whether diode, disk or fiber lasers. There are no limits here.
In early summer, Arnold will be installing another brake disc machine, the BrakeTwin put into operation. An absolute first. More details will be available here in the news in due course. Stay tuned.
Legal background: From 2027, particulate matter emissions must be gradually reduced to 3 mg/km
Technical possibilities: Hard-coated brake discs. Laser coating is emerging as the most efficient option
Additional advantages: Hard-coated brake discs are less susceptible to rust
