(Remote diagnostics also possible) • Equipped with automatic threading device for inserting the grinding wheel into the tooth gap • The machine operates with three grinding methods: a. Generating grinding with CBN grinding worms = fastest processing b. Profile grinding with CBN profile grinding wheels (one or two wheels) = highest precision machining! c. Combination of a and b (most economical solution): pre-grinding with grinding worm / finish grinding with the profile grinding wheel in single part operation • Automatic shifting of the grinding worm or automatic positioning of the profile wheel • Automatic workpiece loading device with a ring loader mounted to the counter column, which automatically loads raw and finished parts. The workpieces are conveyed to the ring loader via a separate FLEX LINK chain conveyor, picked up and also removed. This enables unmanned operation. • Hydraulic workpiece clamping in the table, but without clamping fixtures. Tailstock carriage is present on the counter column, but without tailstock itself. Carriage stroke up to approx. 350 mm • Complete work area enclosure with sliding door and separate CO2 extinguishing system/IR sensor No original coolant system (since there is central supply), and no dresser available Condition : good to very good – demonstration ready under power, compact design! Delivery : ex stock - as inspected Payment : strictly net - after receipt of invoice We appreciate your interest – over 200 gear machines in stock at all times.
