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

Optimized heat treatment Standard heat treatment

Hobs for Dry Gear Cutting

Optimized material :

High performance PM Steels and

or carbide for small module

coating solutions for dry cutting

Special surface finishing

Easy chip evacuation

FUBRI is a company specialized to design and produce also hobs with a

module up to 33 mm.

The big module hob normally has a standard profile, but FUBRI can produce

also big hobs with special profiles.

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

Roughing hobs

First tooth

Second tooth

Reduced height of the tooth

Reduced thickness of

second tooth

FUBRI produces the big module hobs with a new technology

able to save production time and to cut up to 50% the

delivery time.

A special production line, with unconventional machines

tool, can solve the emergency problems of the customers

with a very quickly delivery.

In the same time the accuracy is guaranteed.
