The grinding wheels are kept flat and parallel to each other. The springs are placed in a rotary carrier plate and passed between the wheels many times while the top wheel is fed down incrementally.
The rotation of the carrier plate and top wheel movement are controlled by servo motors. Downward cutting and grinding time is programmable, to avoid spring burnt out and achieve tighter tolerance of squareness and spring length.
