The difference between the gear hobbing machine hob hob with single and multi line please tell me what it is
Hob line number is the number of teeth, that is, the relative movement of the tool and the workpiece. Single track hob refers to the hob turn, the workpiece to a tooth. Double line hob refers to the hob turn, the workpiece to two teeth, and so on in turn. The more the number of hob, the higher the machining efficiency.
This is actually very simple as long thread form almost but the gear ratio will turn to recommend a specific group of host is the expertise of 124669105 mechanical processing technology alliance
Multi thread hob is long hob, 2 to 3 head, high efficiency, the processing of gear precision is lower. Single track hob is a single head hob, relatively speaking, the processing of gear less efficient, higher processing accuracy. The head number is also called the number of teeth. The number of teeth of the hob is not the number of teeth cut in a circle. That is called the number of grooves, which is easily mistaken for those who are not in the trade.
Multi thread hob is long hob, 2 to 3 head, high efficiency, the processing of gear precision is lower. Single track hob is a single head hob, relatively speaking, the processing of gear less efficient, higher processing accuracy.The knife tooth gear cutter for spiral arranged along the cylindrical or conical, used for gear, processing method according to the exhibition of cylindrical worm and other cylindrical workpieces with tooth (see gear, gear). According to the different uses, the hob can be divided into gear hob, worm gear hob, non involute generating hob and fixed hob, etc..
