The areas of application of the particular methods can be briefly summarized as follows.
Discontinuous Generating Gear Grinding with two Disc Grinding Wheels:
• gear quality up to quality 2 according to DIN 3961 [DIN78],
• long machining durations,
• suitable for gears up to module 36 mm and about 5 m external diameter,
• single production, especially dressing tools,
• machining occurs with conventional grinding wheels.
Discontinuous Generating Gear Grinding with a Double-Tapered Wheel:
• average to high gear quality (quality 3 to 6),
• average to short machining durations,
• also applicable for large gears up to module 40 mm and about 4.5 m external diameter,
• very flexible handling,
• machining occurs with conventional grinding wheels.
Continuous Generating Gear Grinding with a Grinding Worm:
• average gear quality (quality 4 to 7),
• suitable for gears up to module 8 mm and about 0.8 m external diameter,
• batch and small batch production, less suited to single production,
• machining occurs with conventional grinding wheels or with galvanically bonded cBN grinding wheels.
Discontinuous Profile Grinding:
• average to high gear quality (quality 3 to 6),
• the only possible method to produce gear rings,
• high flexibility in NC dressing control,
• machining occurs with conventional grinding wheels or with ceramically or galvanically bonded cBN grinding wheels.
Continuous Profile Grinding:
• average gear quality (quality 4 to 5),
• very short machining durations (1 to 3 s/tooth),
• suitable for gears up to module 3 mm and about 0.14 m external diameter,
• large match production,
• machining occurs with conventional grinding wheels.
