Etapas da usinagem no compressor Scroll

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

    Canais para elementaos de vedacáo

    • A pré-usinagem e a usinagem de acabamento dos canais são realizadas com ferramentas para mandrilamento PCD de duas facas 
    • A ferramenta combinada permite a usinagem dos furos de conexão 
    • A distribuição do corte reduz as forças de corte e garante a formação ideal dos cavacos 

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

    Precisão no furo de rolamento

    • 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
