The future brake disc
Coated brake discs set new standards
They offer corrosion protection, reduce particulate matter and meet the requirements of the Euro 7 standard. Coated brake discs ensure consistent and reliable braking performance in all vehicle classes.
Maximum precision for the production of Euro 7‑compliant brake discs
Whether passenger cars, sports cars or trucks – the grinding of coated brake discs places the highest demand on dimensional accuracy, surface quality and process reliability. The Supfina Planet BD meets these requirements with patented, force-neutral processing kinematics, double-sided grinding for maximum efficiency and an innovative clamping and loading system.
Thanks to its flexible design, the Planet BD can machine brake discs of various sizes – economically, precisely and with short cycle times.
Depending on customer requirements, Supfina supplies the Planet BD as an individual solution for integration into existing lines - or as a complete system, including automation. This enables a continuous, perfectly coordinated process chain - from a single source.
One solution for all vehicle classes – with experience from over 30,000 processed brake discs.
Supfina's Solution:
Planet BD
Double disk grinding machine from the proven Planet series for grinding coated brake discs
- Double side grinding (simultaneous machining on both friction ring surfaces) for high throughput / short cycle times
- Coating and grinding as a complete solution as an option
- Maximum quality through innovative process control, optionally with in-process gaging
- Optional automation of loading and unloading for various feeding and discharging systems
- Significant cost reduction by optimizing the process chain coating – double surface grinding
- Safety thanks to Supfina experience
Economical grinding of carbide coatings
Are you already grinding your brake disc or is your brake rotor still grinding the grinding wheel?
Hard material grinding is a challenge for both grinding machine and tool. Especially when tungsten, titanium or niobium carbide has been applied by laser cladding (LMD), extreme high speed laser cladding (EHLA), high velocity oxygen fuel (HVOF) or cold gas spray technology.
The - depending on the coating process - not insignificant heat input into the workpiece can lead to distortion, which affects the final quality. A tailor suited grinding process adjusts the structure and roughness of the friction ring surface for optimum braking behaviour and restores axial run-out and thickness deviation for uniform braking behaviour.

Supfina offers the economical solution
Back in 2019, we began working with brake disc manufacturers, automotive OEMs and coating system solution providers to develop cost-effective grinding solutions for the production of coated brake discs, taking the entire additional process chain into account.
Right from the start, it was important for us to understand the process from powder to coating to grinding itself in order to be able to provide the market – together with our partners – with systems that work and are as cost‑efficient as possible.
Success that counts
Over 30,000 coated brake discs have already been successfully ground with our Planet BD machines - in real applications and with high repeat accuracy.

Brake discs for trucks
Precise grinding - even for XL brake discs
Brake discs for commercial vehicles have special requirements: Not only are they significantly larger, they often have massive pots with complex geometries.
With its high removal rate and stable processes, the Supfina Planet BD delivers precise results – even with heavy truck brake discs.
