Tungsten carbide slotting cutter, a type of gear machining tool, is gear-shaped or rack-shaped. It can be used in machining inner gearing and outer gearing spur gears and helical gears through generating method.
The precision of standard tungsten carbide slotting cutters can be divided into class AA, class A and class B according to the international standard. Normally, they are used to machine gears with precision of class 6, class 7 and class 8 respectively. Gears that need shaving or grinding again for the needs of machining should adopt pre-shaving or pre-grinding slotting cutters respectively to ensure there is a certain amount of machining allowance on the gear surface. Therefore, the teeth shape of these slotting cutters needs special design.
Tungsten carbide slotting cutters can be classified into four types according to its shape: disk, bowl-shaped, cylindrical, taper-shank. Disk slotting cutters are mainly used in machining inner gearing and outer gearing spur gears, helical gears and herringbone gears. Bowl-shaped gears are generally used to machine inner gearing spur gears with circular bead, which are different from disk slotting cutter in that when they work, nuts can be placed inside the slotting cutter and thus will not hamper machining. Cylindrical slotting cutters are used in machining inner gears and outer gears with small modules. Taper-shank are mainly used in machining inner gearing spur gears and helical gears.
