Gear cutting machine, end mill and form milling method

Abstract

The present invention relates to a gear cutting machine, an end mill and a form milling method. The gear cutting machine performs gear cutting for a workpiece, especially performs gear cutting for a tooth-form wheel disc, through a forming mill having at least one tool rest used for installing at least one end mill, wherein, the tool rest or the end mill and / or workpiece support are adjustable, an axis of the end mill can be arranged into a processing tooth surface approximately parallel to a clamped workpiece, and wherein, an axis of a tool is suitable for a contour of the tooth surface, and the end mill has an outer contour corresponding to the contour of the tooth surface.

Description

technical field [0001] The present invention relates to a gear cutting machine tool for cutting teeth of a workpiece, especially a toothed wheel, by performing form milling with an end mill. Background technique [0002] Tooth milling cutters in the form of end mills are used on gear cutting machines for cutting teeth of toothed discs and milling worm gears depending on the forming method. The use of such end mills starts with eg module 10 toothed discs and extends to the largest cutting tooth sizes. When milling worm gears, these end mills are also used in very small modules to machine worm gears and worm discs. [0003] Tools in the form of end mills or, even better, flank milling cutters are also used to pre-mill large cutting teeth. End mills are preferably used where no other tool can be used, for example because of collisions, such as when machining closed herringbone gears, when machining double helical gears with a small intermediate space, or where there is no sui...

Problems solved by technology

In order to avoid local overloading of the tool, the tool speed must therefore be adjusted, which results in a longer overall machining time
