Processing steps on the scroll compressor

  • The combination tool finishes the recesses for the sealing grooves.

    Recesses for sealing elements

    • Pre-machining and finish machining of the recesses is carried out with double-edged PCD boring tools
    • Combination tool enables the machining of the connection bore
    • Distribution of the cut reduces cutting forces and ensures optimal chip formation

  • The boring tool with two stages machines the bearing bore of the scroll compressor.

    Precise bearing bore

    • Pre-machining is carried out by circular milling with a triple-fluted PCD milling cutter
    • Finish machining with double edge PCD boring tool with two stages and distribution of the cut to reduce the cutting forces

  • Machining of the high-precision spiral shapes with a milling cutter made of solid carbide.

    High precision spiral shapes

    • Pre-machining and finish machining with solid carbide milling cutters
    • Extremely sharp cutting edges ensure high dimensional accuracy
