Heat Treatment
• Heat treatment process gives the hardness , but it is not enough to achieve high
performances
• With optimized parameters Fubri obtained better Toughness and better fatigue
resistance which :
• decrease the risk for micro-chipping

Roughing hobs
This type of hob has two different shape
of teeth in order to better divide the amount
of material removed
The roughing hob is based on:
About 75% of removed metal takes
place in tip area of cutter teeth.
The tip radius determines the duration of
service life
Large number of gashes (MAXIMUM FEED)
ECONOMICAL AND EFFICIENT HOB
