Gashes for Involute Gear Hob

Gashes for Involute Gear Hob

A high number of gashes increases the cutting capacity of the hobs and the density of the envelope network; they do however also reduce the useful tooth length, unless the cutter diameter is increased accordingly. 

For solid type hobs the gashes are up to a helix angle of 6° made axially parallel and over 6° with helix. For more details on gear cutting tools and involute gear hobs, please get in touch on our website.
