Bierther Submikron lapping discs – For maximum precision and efficiency in surface finishing
Bierther Submikron Sanding discs stand for Precise surface finishing with uniform material removal and high accuracy in terms of Flatness, Planar parallelism and Roughness. Depending on the application, different types of grinding wheels are used – including bonded abrasive wheels as well as diamond and CBN grinding wheels for machining hard materials such as ceramics or hard metal. The low process forces enable stable and reproducible results while maintaining high removal rates.
Sanding discs
- Uniform material removal
- High planarity and precision
- Low process forces
- Long service life
- Efficient and economic processes
Your advantage By using modern lapping discs, processing can be made significantly more efficient, as high material removal rates are combined with excellent surface quality.

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
High-performance grinding discs offer high material removal rates, long service lives and an economical alternative to diamond and CBN grinding discs. They prevent wash-outs in soft material zones, thereby reducing surface defects such as „orange peel“ in subsequent polishing processes.
In many applications, water suffices as a coolant, significantly simplifying cleaning and process handling. Typical areas of application include the production of cutters, shears, and knives.
Silicon carbide disc
- available in grit sizes F80-F1500

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
For combined processes, we also offer composite polishing pads and bi-composite polishing pads.
