Which is more tiring, hobbing machine or gear shaper?
Gear shaper is tired. The tooth profile accuracy of hobbing is lower than that of slotting, and the number of tangents forming the tooth profile envelope is only related to the number of chip grooves and the number of basic worms of hob, and cannot be increased or decreased due to the change of machining conditions. So it needs less energy than the gear shaper, so it is easier. Gear shaper is a tooth surface machining method for machining internal and external gears or racks on gear shaper with gear shaper cutter.
