The universal gear grinder HOEFLER, Model H 1250, has wear-free guides, and the table hydrostatic slides. This grants highest grinding quality. The numerical control is equipped with a diagnostic system for data communication, central -, interpolation-, and adjustment-processor, as well as for programme memories. The diagnostic system recognizes programme errors and gives information and status messages. Errors are indicated in a plain language. In case of a break down of electric current the grinding wheel leaves the gear immediately to avoid damages. Memory programs simplify the production of gears in series. The machine can grind in one flank -, two flank- or contact line grinding. The CNC drive corrects smallest irregularities. The machine is equipped for meshing and flank line corrections. The machine table is equipped with a regulation of peripheral speed for checking the dividing process.
