Gear shaping is a flexible process to manufacture internal and even external gears. Especially, to manufacture internal gears or external parts with interfering contours, when gear hobbing is not possible. For these applications, gear shaping is the most chosen process.

Gear shaping belongs to the generating process due to its continuous rotational movement during the operation. The workpiece and the tool form a pair of gears where the rotation speed of these partners is coupled by the number of teeth ratio. The gear profile is generated by the rolling action on the same pressure line. During the operation, a stroking motion of the tool is needed to ensure the cutting operation. This oscillating cutting movement (cutting stroke and return stroke) is realised by the simultaneous radial feed of the tool on the desired profile. During the return stroke, the tool is raised from the gear by a special raising system to prevent any scraping on the tooth flanks and to avoid significant tool damage. To reach the defined tooth height of the workpiece, the centre distance between the partners is adjusted continuously until the required geometry is reached.

Gear shaping and shaper cutters Samputensili

Samputensili offers a wide range of shaper cutter geometries to the market, see picture below. Due to customer demands and the workpiece geometry, it is possible to use disc-type shaper cutters, shank-type shaper cutters, deep counterbore-type shaper cutters or internal hub-type shaper cutters.

In close collaboration with our customers we choose the best fit combination out of geometry, cutting material and coating for the tool regarding its future application. We can offer shaper cutters out of high speed steel, MC90 or carbide. Furthermore, we offer all well know coating solutions such as Futura Nano, AlcronaPro or Altensa.
