Small modulus involute gear milling cutter structure and tooth profile design requirements

The structure and tooth profile design requirements of small modulus involute gear milling cutters are as follows, for reference and understanding.

Small modulus involute gear milling cutter structure:

There are two types of small modulus gear milling cutter structure, with shoulder and flat shoulder, no matter it is processingInvolute gearOr machining cycloid gears or other non-involute gears.

The commonly used milling cutter materials are: high-speed tool steel and cemented carbide.

Tooth profile design requirements for small modulus involute gear milling cutters:

Knowing from the formation principle of involute tooth profile, those with the same modulus and different numbers of teethgear, Due to the different diameter of the base circle, the involute tooth profile is different.

Therefore, theoretically speaking, gears with the same modulus and different numbers of teeth require special milling cutters.

In order to reduce production costs and simplify tool management, standard modular gear milling cutters are classified in actual production, and each milling cutter processes involute gears with different tooth numbers but the same modulus within the specified range.
