The increasing requirements for bore grinding applications using dressable CBN abrasive tools have required yet another step towards an even more optimised bond. As a market leader in the field of vitrified CBN wheels, Meister Abrasives is enlarging its range of high-performance tools to meet these demands.
The already successful HPB (High-Performance Bond) systems must be developed further to meet the needs of customers seeking to achieve ever-higher stock-removal rates for very small bores while optimising surface quality at the same time.
Under the designation HPC for High-Performance Cutting, the company has succeeded in enhancing still further the benefits of the Meister high-performance tools, especially in fine abrasive grit sizes from 500-1500 mesh.
The result – stock-removal rates which compare favourably with far coarser grits, combined with much finer surface qualities, while the greatly increased dressing intervals give an added boost to cost-effectiveness.
For very small abrasive grit sizes therefore, this new development in bond technology offers unequalled:
- Pore volumes
- Reductions in cutting forces
- Stock-removal rates
- Improvements in component geometry
- Dressing intervals
The company's technological approach is based on the use of strength-enhancing synthetic raw materials which improve the bond's toughness and the grit retention forces.
Although aimed primarily at applications using very fine CBN grits, the technology is also basically suitable for coarser grit sizes.
