Most gears are made of alloy steel and therefore milling will be a key challenge when processing gears without heat treatment and tempering in automatic lines. When gears are processed according to machining after heat treatment and tempering, it is important to choose a hard cutting CNC tool to solve the EDM process and reduce machining costs.
       

The productivity of the external turning process can be maintained with reasonable milling adjustments, efficient turning of internal diameters and ring grooves, efficient turning of internal diameters and flanks, maximum productivity improvement when milling tooth mouths, productivity of the hard cutting process when milling end faces and finishing hole diameters with tool radius compensation, safe and reliable interrupted grooving processing while minimising processing times, safe and reliable external finishing during interrupted hard cutting processing, and productivity of the hard cutting process during interrupted finishing of end faces and timing gear cones.
