16 Quality All tools are delivered with control certificate Every manufacturng step are controlled The modern checking equipment guarantee an absolute reliability The hobs are manufactured following definite tolerance classes. These are DIN3968, ASA B , BS (Class A AA AAA)

17 Coatings Highs Performance Coating The coatings are selected based on gear cutting operation and particularly in relation with the cutting speed TIN : TICN ALTIN : ALCRONA: TIALCRN ALTISIN

18 Coatings Multi Layers Technology In order to increase the performances of the coating film, we use the Multi Layers Technology with different type of material for each layer. TiCN layer TiAlN layer TiCN layer Substrate

19 Technical Assistance & After Service FUBRI can supply the following services Technical assistance during the design and the in the initial stage of production (choice of tools and time optimization ) Information on working conditions for cost optimization Expert after sales assistance in order to solve possible problems during the use of tools Manteinance of tools (resharpening, recoating, etc.)

20 HOBS

21 HOBS We supply all types of hobs: HSS from MN 0.3 to MN 33 up to Ø 310 Carbide up to MN 4 Spur type Shank type Heavy duty Parallel side spline Roller chain sprocket Pulley Special hobs to customer specification

22 Some example of special hobs produced by FUBRI Double hob for roughing an finish operation in the same working cycle Hob for air compressor rotors Hob without centering bore for high production hobbing machine

23 Some example of special hobs produced by FUBRI Roller Chain sprocket hobs Special profile hos Hob without centering bore for high production hobbing machine

24 Precision class: The hobs are manufactured following definite tolerance classes. These are DIN3968, ASA B , BS , which define: Quality: AAA very high precision ground profile; AA high precision ground profile; A precision ground profile; B standard ground profile. Standard accuracy for FUBRI hobs is DIN 3968 class AA

25 Precision achievable with different process and tools Gear accuracy class 25

obtained better Toughness and better fatigue resistance which : decrease

26 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

coating solutions for dry cutting Special surface

27 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 Dry cutting with a hob ALTIN coated

28 Big module hobs 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. Module Ø L Bore

29 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

30 Roughing hobs Reduced thickness of second tooth Reduced height of the tooth First tooth Second tooth

31 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.
