Expanding the options of SMG405GF3 gear grinding machine

While producing the grinding machine for the customer we faced with the need to manufacture of eight parts of “pulley wheel” type of different diameter. To do this, we turned to a contractor, but the timing and cost did not suit us.
Our technologists offered to manufacture the pulleys on our own using the SMG405GF3 gear grinding machine.
The advantage of grinding the pulley teeth as a whole is that there is no milling with special cutters, as well as the elimination of the problem with bending and vibration of end tools with a long overhang.
This method allows producing pulleys with the up to 550 mm diameter on the eth SMG405GF3 machine for any belt profile and number of teeth.

The full production cycle of a 112-teeth pulley including measurement by the built-in measuring system was 6 hours
The following accuracy parameters have been achieved:

·       profile wave - 6 micron,
·       accumulated cyclic error 0,011 mm,
·       lead variation 0,002 mm.
