Bierther Submikron lapping discs – For maximum precision and efficiency in surface finishing
Flat grinding wheels are characterised by their very high removal rates and achieving high accuracies the workpieces, in relation to Roughness, Flatness and Planar parallelism, aus. Thanks to diamond and CBN grinding wheels, it is possible to machine hard materials such as ceramics or hard metal. Advantages: Low process forces and maximum accuracy! We supply the right wheel type for your requirements: round, hexagonal or segmented.
Cast iron lapping disc
The cast qualities used are characterised by Cinder-free, homogeneous base structure with uniform graphite distribution in form, size, and small hardness differences across the entire cross-section.
Possible grooves Ungeared, radial groove, waffle groove, spiral groove
Steel lapping disc
We predominantly use S355 one, which has undergone heat treatment to eliminate stresses from the material.
On request, we supply all desired steel grades.
Possible grooves Ungeared, radial groove, waffle groove, spiral groove
Support disk
These unused discs serve as reliable pulley unit in continuous use for polishing discs and polishing cloths. Versions available in: Aluminium (optional with non-stick coating), cast iron, steel, granite.
Copper lapping disc
For all types of lapping machines, we supply the matching lapping discs and segments made from Copper.
Possible grooves Ungeared, radial groove, waffle groove, spiral groove
Bronze polishing disc
For all types of lapping machines, we supply the matching lapping discs and segments made from Bronze.
Possible grooves Ungeared, radial groove, waffle groove, spiral groove
Tin-plated disc
For all types of lapping machines, we supply the matching lapping discs and segments made from Zinn.
Possible grooves Ungeared, radial groove, waffle groove, spiral groove
Grinding discs for grains
Bonded abrasive discs are distinguished by high removal rates and long service lives, and offer a cost-effective alternative to diamond and CBN grinding wheels for many materials. The use of bonded abrasive discs prevents the washing out of soft zones on workpieces that occurs when lapping with loose abrasive, which also avoids the „orange peel“ effect that frequently occurs during subsequent polishing processes for some materials.
A positive side effect is that in most cases, only water needs to be supplied as a cooling liquid for the solid grinding discs made of silicon carbide or aluminium oxide. As a result, no lapping sludge is produced and cleaning of the workpieces becomes considerably easier.
A widespread application method for grinding discs lies in the manufacture of cutters, shears, and knives.
Silicon carbide disc

Nut types
Unused
- Application: small parts, polishing pad backing disc
- Advantage: lower tendency to scratch, lower lapping agent consumption
Radial nut
- Maximum depth 40 mm
- Application: Standard Products
- Benefit: cost-effective, higher material removal rate than with non-grooved discs, better flatness
Waffle nut
- Maximum depth 40 mm
- Application: Double-sided lapping machine, high flatness requirements, difficult-to-machine materials
- Benefit: cost-effective, higher material removal rate than with non-grooved discs, better flatness
Spiral nut
- Max. nut depth double nut width
- Application: High flatness requirements, difficult-to-machine materials
- Advantage: higher removal rate and better flatness than with radial grooves
