Although the volume of precision gear is small, it is also a part that many mechanical equipment need to use. So what kinds of cutting tools are there for precision gear machining?

1. Gear slotting cutter this is an external gear that seems to have the meaning of a blade. Because the gear is higher, it is called gear slotting cutter. When cutting, the wheel embryo and the prop make meshing movement according to a certain transmission ratio. And the cutting tool moves up and down along the axis to cut the tooth width.

2. Rack slotting cutter: the rack slotting cutter is a kind of gear profile that is the same as the standard rack, but the gear should be higher than a part, and the higher part of the tooth top is the same as the arc.

3. Gear hob: the shape is very like a screw, but the profile is a rack tool. When using this tool, in order to cut straight teeth parallel to the axis of the gear blank, it is necessary to rotate the axis of the tool to the rising angle of the next screw.

Differences between various knives: the several knives introduced above are not only very different in shape, but also in different places. When these cutters are installed on different gears, we should pay attention to what kind of cutters each gear should match.

Material of cutting tools: because different cutting tools are made of different materials, we should try to choose the right cutting tools when choosing cutting tools.

The above is an introduction to the precision gear processing tools. If you need precision gears, you are welcome to consult IHF Hefa gear manufacturers.
