Flat & Profile Grinding
Flat grinding is our core process for the fine and finish machining of flat workpiece surfaces. On Mägerle machines we clamp workpieces magnetically, by vacuum table or with mechanical clamping systems such as Erowa — depending on material and geometry. Profile grinding enables the production of complex contours to drawing — from gear profiles to guideways and special tools. The combination of high-precision machines, dressed profile grinding wheels and decades of experience guarantees dimensional accuracy in the micron range. Depending on requirements, we use reciprocating grinding, plunge grinding or creep-feed grinding.
- Surface finish to specification
- Repeatability for series
- Contour variety through profile grinding
- Almost all materials can be processed
Double-Disc Grinding / Flat Honing
Double-disc grinding is the method of choice for the highest requirements in flatness, parallelism and thickness tolerance. On Peter Wolters machines, workpieces are placed in externally toothed carrier discs and simultaneously ground on both sides between two grinding wheels. The key advantage: with rolled, stamped or forged components, material stresses are neutralised by the simultaneous grinding of both surfaces. The result is particularly flat workpieces — even from difficult raw materials. Compared to conventional lapping, this process significantly reduces machining times.
- Flatness through two-sided machining
- Parallelism of outer surfaces
- Tight thickness tolerances (±0.005 mm)
- Clean parts, easy to maintain
Clamping Technology
Magnetic clamping
For ferromagnetic materials. Fast setup, uniform holding force across the entire surface.
Vacuum clamping
For non-magnetic materials such as titanium, brass, aluminium or ceramics. Gentle fixation without deformation.
Zero-point (Erowa)
Maximum repeatability for series production. Fast changeover, reproducible positioning.
Mechanical Clamping
For complex geometries and special cases. Individual solutions depending on workpiece shape.
