There are various types of cutters which include gear shaving cutter and gear shaper cutter among others. Gear shaper cutter, is actually a gear that has teeth with appropriate clearances and cutting edges capable of cutting different types of gears. Its stroking and rotation functions facilitate the process of molding generation. They are used in the production of things such as clutches racks, gears, racks and several others. Where hobbing cannot be used because of difficulties in accessibility, the gear shaper cutters may be used instead.
A gear shaving cutter is a device that is used in the final process after roughing using a hob or a sharper has been completed. In the shaving process, tiny amounts of metallic particles are removed from the gear teeth’s working surface whereby chips which look like hair are produced. This ensures that the finishing of the tooth surface is much better and also there are no load concentrations of the tooth end. The shaving process facilitates the reduction in the noise produced by the gear and this increase gear’s load power and repair life.
Gear shaving is a very important aspect in the process of gear cutting. Though it does not provide the required standard, it only cuts off small amounts of metal so that the final product is within 6.5 Micro meters .The process that follows is what eliminates the error or reduces it so that it becomes negligible. The process can only be completed after the teeth have been hardened. This process is quite ideal especially for making gear box gears but works well before the gears are hardened.
The shaving process concentrates on meshing the gear with a cutter that has serrations which cuts the edges of the teeth being worked on. If the gear is helical, it is advisable to a spur gear so that it is possible to mount the cutter at an angle to the axis of the gear. When using the gear shaving cutter, it is advisable to use traverse shaving where the shaving is done and the gear reciprocates in the direction of its axis.
Gear shaving cutters work well if the process of cutting employs dry cutting and which should be done at a high speed. High speed cutting is known to reduce the tool costs because it makes the life of the tool longer. Dry cutting also reduces the cost of cutting because no oil is used. If the process is strictly followed, it improves the life of the gear. Gear cutters can also be used by people who are not highly skilled as long as they follow the laid down procedure and instructions. The cutters are also user friendly and can serve one for a long period of time if they are maintained.
