Radia Breaker – Exact radii profiles for maximum process reliability
When it comes to exact radii profiles, a standarddressing device fast at the limit. Our radii dressing device has been specially designed to shape convex and concave grinding wheel geometries precisely, reproducible and stable in internal and external grinding – with a transverse shape deviation of maximal ±1 μm.
What do radii dressing devices – and when do you need them?
Radia dressing equipment are used wherever grinding wheels are to receive exact, reproducible radii profiles – for example for tools, fit surfaces or shape contours with high quality standards. They enable the targeted alignment of concave and convex radii and thus ensure constant grinding results, narrow tolerances and smooth surfaces.
In contrast to standard solutions, they are specially designed for swivelling – with play-free mounting, driven radius axis and variable tool mounting. Whether single-grain diamond or rotating diamond roller: radii dressing devices are a central component for stable grinding processes in complex profile requirements.

Radiating device RAS-400×175
The RAS-400×175 radii dresser has been specially designed for precise alignment convex and concave radii developed on external circular grinding machines. It is mounted directly on the machine table and is mounted on both sides with high accuracy – ideal for use with high timing. The radius movement takes place via a servomotor with play-free harmic drive transmission. The diamond roller is driven by the proven dressing spindle AS58x94F/025. Alternatively, the system can also be used with a single grain diamond.
Technical data:
- Maximum adjustable radius: R = 20 mm
- Largest grinding wheel Ø: 400 mm
- dressing spindle AS58x94F/025
- Diamond roller mount Ø: 20h2 mm
- Diamond rollers clamping width: 10 mm
- Diamond rolls outer Ø: 60 mm
- Speed of fat burning: max. 22000 min-1
Radiating device RAS-610-R65
The RAS-610-R65 is specialized in precise alignment of concave radii and is ideal for large grinding wheels up to Ø 610 mm. The radius movement takes place via a servo drive with non-playing harmonic drive transmission. The feed of the individual grain diamond is controlled and pneumatically clamped by a stepping motor. The system is designed for maximum accuracy, high repeatability and reliable operation in daily series.
Technical data:
- grinding wheel Ø 610
- R max. = 65 (concav)
- Single grain diamond: Ø 8 x 35
RAS-125-01 Radiator
The RAS-125-01 is a compact, fly-mounted radii dressing device for precise individual grain alignments. It is designed for grinding wheels up to Ø 120 mm and radii up to R = 25 mm. The pivoting movement of the dressing arm is effected hydraulically, the radius movement takes over a servo drive with harmonic drive transmission. After alignment, the system automatically returns to the rest position – ideal for applications with a clear clock structure and limited installation space.
Technical data:
- Maximum adjustable radius: R = 25 mm
- Largest grinding wheel Ø: 120 mm
- single cornealing diamond: Ø 8 x 35, 1 carat
RAS-118-01 Radiator
The RAS-118-01 has been developed specifically for use in internal circular grinding machines with narrow installation spaces. Equipped with a dressing spindle AS58x94F/025, it is suitable for grinding wheels up to Ø 120 mm and radii up to R=25 mm. The pivoting movement takes place hydraulically, the radius movement is carried out by means of a compact direct-current transmission motor with reduction. After alignment, the arm automatically returns to the rest position – ideal for confined spaces and repeatable profiles.
Technical data:
- Maximum adjustable radius: R = 25 mm
- Largest grinding wheel Ø: 120 mm
- dressing spindle AS58x94F/025
- Diamond roller mount Ø: 20h2 mm
- Diamond rollers clamping width: 10 mm
- Diamond rolls outer Ø: 60 mm
- Speed of fat burning: max. 22000 min-1
Radiating device ABV-320F/001
The ABV-320F/001 is a flyingly mounted dressing device for circular grinding machines, designed for convex and concave radii Wheels to Ø 500 mm. The radius movement takes place via a servo drive with a screw gear that can be adjusted without play. By default, single-grain diamond is executed; alternatively, Diamond roller are used – driven by dressing spindle AS58x94F/026. The device convinces with flexibility, stable guidance and high repeatability with varying disc diameters.
Technical data:
- grinding wheels Ø: 400 mm; radius concave max. 30 mm; radius convex max. 20 mm
- grinding wheels Ø: 500 mm; radius concave max. 30 mm; radius convex max. 10 mm
- Single cornealing diamond: Ø 9.52 mm x 35 mm
