DYNAMIC DIAMOND DRESSING TOOLS (ROLLERS)


DIRECT ELECTROLYSIS (G+)

This is used to dress vitrified CBN and conventional grinding wheels.
The diamond is deposited directly on the part with the desired profile by a nickel-based electrolytic process. A single, high-concentration layer is randomly deposited on the part. Once the diamond is deposited, it is then dressed to achieve the desired tolerances. These rollers are low-cost, have good tolerances and have very good cutting capacity.
They are usually used for short series.

INVERSE ELECTROLYSIS (G-)

This is used to dress conventional grinding wheels. The diamond is deposited by an inverse electrolytic process using a graphite mould.
A single, high-concentration layer is randomly deposited on the part.
Once the diamond is deposited, it is then dressed to achieve the desired tolerances. These rollers allow very small profile radii (concave and convex) and can work to extremely strict tolerances.

INFILTRATION PATTERN (S-)

This is used to dress vitrified CBN and conventional grinding wheels.
Very hard bonding agents are used at very high temperatures to ensure strong diamond adherence. It is possible to achieve strict tolerances because, after sintering, the surfaces undergo high-precision optical grinding. These tools are generally manufactured from natural diamonds specifically selected for this tool type, or from synthetic diamonds with the geometry required by the roller. PCD and CVD are also used to dress conventional corundum grinding wheels.

INFILTRATION RANDOM (SAC-)

This is used to dress vitrified CBN and conventional grinding wheels.
The tools can be made of either synthetic or natural diamonds.
Although diamond distribution during sintering can be random, concentration is controlled at a pre-determined level, allowing several dressings to be performed to regenerate the profile after use.
