High speed in gear technology

The Felsomat Flexible Hobbing Center 80 is providing the competitive edge in manufacturing with a perfect mechanical engineering. Especially developed for high speed cutting (HSC process) for transmission manufacturing, the FHC 80 is reducing the machining time to a level deemed unreachable so far. In combination with an ultra rapid integrated loading system it is possible to achieve machining times less than 8 seconds per work piece – and all this with a minimum of floor space and a maximum of work area.

High Performance Facts:
Chip-to-chip time < 1 second due to
Loading/unloading parallel to the hobbing process
Pendular machining with 2 spindles
Lowest cost per piece and longer tool life
Ideal for dry machining
Rigid and sturdy work piece –and tooling spindle increased cutting parameters and tool life.
Shorter cutting times due to higher material removal rate
a higher material removal rate
Finish machinig in final quality IT4 to IT5 with the single cut or a dressing cut process
More than doubled life cycle time with two spindles with lower acceleration and deceleration
The high productive 2- spindle hobbing center is equipped with a tailstock and a tension rod with a closed force loop
Easy change over through excellent access and an ergonomical work holding and hob tool change < 10 min.
Easy operator interface with intelligent technology software package
Singular construction design with lift hooks for easy redeployment
For a multitude of manufacturing possibilities:
Parallel to main processing time push-roll-deburring with fettling wheel and elimination oft he resulting scondary burr at the flank with the dressing cut
Finish machinig in final quality IT4 to IT5 with the single cut or a dressing cut process
Convenient tool change:
To change the hob cutter, the hob head is swivelled into a vertical position prior to the operator accessing the work area. Based on the excellent access and the use of both hands a hob cutter change is possible in only 30 seconds.

Precision to the µm, day after day, year after year
All hobbing machines of the FHC platform have a mono-block machine base made from mineral base concrete for maximum rigidity with optimum damping characteristics and high dynamic axis servo drives. Direct driven synchron motors for the work piece spindle and the tool spindle with high resolution encoders, guarantee a high dynamic feedback control system, highest quality and a long life of the production machine.
