Successful case of using CENTER MASTER™

Assembly of transmission case and oil seal

  • < Experiment result graph >
    • Without CENTER MASTER

    • With CENTER MASTER

    < Experiment result graph >
    • Without CENTER MASTER

      • The maximum insertion load is not uniform in proportion to the positional error.
      • Quality is not uniform because the insertion load is not uniform.
    • With CENTER MASTER

      • The stable maximum pressing load by positional error compensation reduces the defect rate and greatly improves the assembly quality.

Effects of CENTER MASTER™

  • Significantly reduced assembly failure
    Significantly reduced assembly failure
    Compensates for misalignment to significantly reduce assembly failure in insertion or press-fitting
  • Save of lead time and cost effectiveness
    Save of lead time and cost effectiveness
    The amount of time required for a production line -the processing time- is decreased since the precise positioning is not needed and noise and vibration are considerably reduced. And peripheral devices are simplified, so facility investment cost and facility maintenance and repair work are significantly reduced.
  • Uniform press-fit quality
    Uniform press-fit quality
    Uniformly reduced insertion force dispersion by center compensation, drastically decreases defects, and considerably reduces noise and vibration.
  • Enhanced operation rate
    Enhanced operation rate
    Reduced errors result in increased operation rate.
  • Increased binding force between parts
    Increased binding force between parts
    The binding force between parts increases, because the surface contact density is increased by center compensation.
  • Longer life cycle of the assembler
    Longer life cycle of the assembler
    Reduces payload to the assembler to prolong its life cycle and to prevent oil leak and rod distorsion.
