Hobbing Machine FHC 180

Hobbing in a Manufacturing System

The Felsomat Flexible Hobbing Center 180 is setting a new standard in the complete machining of precision gears. Especially developed for high speed cutting (HSC process) for transmission manufacturing, the FHC 180 is reducing the cost per part up to 30% with the integration of chamfering, deburring and parallel loading –unloading in a gear manufacturing system. Highest production within the smallest foorprint.

High Performance Facts:

  • Chip-to-chip time < 1 second due to
  • loading/unloading parallel to the processing
  • pendular machining with 2 spindles
  • Lowest cost per piece and longer tool life
  • Ideal for dry machining
  • Rigid and sturdy work pice –and tooling spindle, Increased cutting paramters and tool life.
  • Shorter maching time due to higher material removal rate
  • Finish machinig in final quality IT4 to IT5 with the single cut or a dressing cut process
  • More than double life cycle time by two spindles with lower acceleration and deceleration.
  • Easy change over through an 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 of the 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 swiveled 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.
