Tungsten carbide keyway broach, as its name implies, is a kind of cutter using for splining.
Types of keyway:
Woodruff keyway has the same keyway size and limit deviation with flat key keyway. Therefore, the tungsten carbide keyway broach can be used in both of them.
Taper key keyway is 0.5~1.3mm shallower than flat key keyway. The groove depth of guide sleeve should be increased if the standard keyway broach is used in splining taper key keyway at one time. But if it is doing for many times (b≥14mm), then the gasket thickness should be calculated again.
Thin flat key keyway is 0.9~3.5mm shallower than flat key keyway, and the groove depth of guide sleeve during splining at one time should be chosen based on the guide sleeve size a. But if it is doing for many times, proper gasket thickness should be selected.
The characteristics of tungsten carbide keyway broach:
I. It has large broaching allowance and teeth number, therefore if the groove is quite deep, then the splining should be done by two times.
II. The broaching surface roughness is relatively high (Ra 2.5~1.25 μm or even higher). When low surface roughness is required, keyway broach with lateral wiper should be adopted.
III. When the guide sleeve is not long enough, the broach may bend upwards and even break during operation.
IV. Edge-line of teeth with enough width should be guaranteed in order to increase broaching stability.
