Rotary Truer and Roller Dressers - ElectroplatedPositive electrolysis: 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 chemical electrolysis process using nickel. 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. This type of roller is economical, has a good tolerance and a very good cutting capacity. It is usually used for short series. Negative electrolysis: This is used to dress conventional grinding wheels. The diamond is deposited by an inverse electrolysis 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. This type of roller allows very small profile radii (concave and convex) and tight tolerances to be achieved. Rotary Truer and Roller Dressers - SinteringThis is used to dress vitrified CBN and conventional grinding wheels.
iamond distribution is random, but concentration is controlled at a pre-determined volume, which allows for several dressings to be performed to regenerate the profile after use. Rotary Truer and Roller Dressers - InfiltrationThis 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. Extreme tolerances are achieved because the tool is an exact negative of a tool previously produced by a profile cutter on an optical grinder. ManufactureThese profile tools are manufactured from natural diamonds specifically for this type of tool, or from synthetic diamonds with the geometry that the roller requires for its task. In both cases, the stones are distributed according to specific criteria. Polycrystalline diamond PCD or CVD is also used to dress conventional corundum grinding wheels. |
