Range of application

The innovative Supfina Race 707 and Race 717 are setting new standards in Superfinishing ball ­bearing inner and outer rings. Both have been optimized to meet the highest productivity demands, while achieving best quality results, fast ­set-up times and superior reliability.

Valuable input from our customers, combined with extensive experience of the Supfina 727 machine types for the large diameter range, are the cornerstones of this newly developed machine concept.

The Race 707 and Race 717 cater to different diameter ranges. While the Supfina Race 707 can machine rings of up to 90 mm diameter, the Race 717 covers a range of up to 180 mm.
