Profile milling
Profile milling is an imaging milling process . This means that the contour of the milling tool is transferred directly to the workpiece. Complicated shapes such as gears, T-slots , prisms, dovetail guides or semicircular guides can be produced on conventional milling machines with tools that are appropriately ground to the profile to be produced.
In profile milling of gears , unlike in hobbing, the cutting movement is only performed by the rotating milling tool while the workpiece is stationary. Here, the workpiece in the universal dividing head is rotated one tooth pitch after each milled tooth gap. A specially adapted disk milling cutter is required for each tooth shape. The milling tools are subdivided between the individual modules and the specified number of teeth (for example No. 8, z = 135 – ∞, m = 1.5).
