Gear Manufacture

Producing gears to high standards is vital for the efficiency, longevity and quality of power transmission systems.

Kumi Solutions provides machines, processes and experience, which improve the quality of the finished product, creating value added benefits, technical and competitive advantages and improved margins.

Hard Broaching

• Reduce undesirable stresses and strains created when centre distances are influenced by poor concentricity between splined bores and pitch circle diameters as a direct result of heat treatment distortions and or less appropriate preceding machining methods.
• Improve the contact ratio between shaft and bore.
• Improve the quality of slide and press fits.
• Enable components to be produced to tighter tolerances cost effectively and quickly.

Gear Honing

• Improvements in power transmission efficiencies through gear quality and reduced drag
• 2-2.5 times more compressive residual stresses than shot peening.
• Reduced transmission noise.
• Reduce face width and weight.
• Hone tighter helix angles than possible with worm wheel grinding.
• Cumulative pitch error correction.
• Favourable surface finishes for oil retention.

Gear Grinding - DSA Units

• Fässler guaranty of quality with 2 micron or better run out.
• The precise profiling of grinding worms flank and root.
• Tip dressing using the optional APV unit or radius roll.
• New units or fixed price overhaul of existing systems.
