Gear shaving cutters

The quality of the serration’s internal surface is critical to enhance the chip flow, which determines the life of the cutting edges and the finishing quality of the shaved surfaces.

TSA has designed a production system of excellence, integrating the most accurate and efficient manufacturing processes in the production of shaving cutters.

  • Use of specially formulated steels
  • Cutting of serrations using its own designed CNC machines
  • Vacuum heat treatment which prevents the accumulation of salts on the inner side of the teeth, maintaining the quality of the finished surface along tool life
  • A second treatment (nitriding) is applied to increase the surface hardness, improving the performance of the tool
