GEAR GRINDING MACHINES

We upgrade MAAG gear grinding machines based on the 0° grinding method by incorporating our topological control systems - with levels up to CNC. A data-compatible substitute for MAAG-topology ES 422 is also available. Suitable MAAG gear grinding machines are:

  • HSS 30
  • SD-32-X
  • SD-36-X
  • HSP-80
  • HSS90
  • others on request
  • SD-32-X or SD-36-X base machines in stock

Operation

Software for input and analysis of topological forms for grinding by the 0° method. Operator aid via graphical area for easy setting and compiling of topological corrections directly on the machine.

Ideal to grind easy a helix bias modification!

Special features:

  • Program for the analysis of topological grinding data for minimizing the grinding wheel thinning. For the zero-degree grinding method.
  • The works-internal webbing of the machines (Data exchanges).
  • Integration of measuring results from external measuring machines as feedback for the production of topological forms.
  • The back-up of the technology data of the company server.
  • A user-friendly graphical surface for the operator via touch-screen.
  • Reliable and maintenance convenient machine control system on a field bus basis (Fiber- Optics)

Result

Reproducible topological corrections on tooth flanks, with short set-up times, highly precise, and at economical cost. Different topological corrections can be ground on the left and the right flank simultaneously.

Applicable for:

  • Shaving cutters
  • Dressing tools
  • Prototype gears

Properties SD-32/36 CNC TOPO

  • Uniformly High Accuracy
    Ensured by the gear grinding principle, the meticulous care used in the manufacture and building of the machines and the rugged machine design with the hydrostatic sliding guides.
  • Same grinding wheels for all pitches
    This means very low tooling costs.
  • Simultaneous grinding of two flanks
    Topological modification left and right
  • Rapid changeover
  • Large machine capacity
    SD-36 up to outer diameter of 360 mm, facewith up to 210 mm and helix angle up to +/- 45°. SD-32 up to outer diameter of 320 mm, facewith up to 210 mm and helix angle up to +/- 45°. HSS-30 up to outer diameter of 300 mm, facewith up to 250 mm at helix angle 0°, 215 mm at helix angle 31° and 130 mm at helix angle 45°.
  • Dry grinding process
    Dry grinding practically eliminates the danger of ‘’grinding abuse’’ and no pollution of the environment.
  • Fully automatic grinding cycle
    With versatile programming facilities for roughing and finishing operations
  • Easy programming of the topological flank modifications
    Thanks the continuously further developing machine software, even without CNC knowledge.
  • Economical
    Through the overhaul and retrofit of an existing Maag machine, we achieve a excellent price-performance ratio.
