[Construction Case] Improvement of Punch Lifespan

Successfully achieved over 16 times lifespan improvement! Case study of New Kanak treatment + PVD (TiN) application.

To improve the lifespan of the core punch, we reviewed the selection of steel types. Previously, we used SKH51 material with CVD-TiC treatment, but the cause of the lifespan issue was the tip of the punch cracking in a ring shape, so we changed the material to carbide. By applying PVD (TiCN4μ) to the new Kanack treatment, we successfully achieved more than a 16-fold increase in lifespan compared to before. 【Case Summary】 ■ Previous Issues - The tip of the punch cracks in a ring shape - Peeling of the PVD coating ■ Treatment Effects (due to increased surface hardness) - Reduced wear - Suppression of chipping and peeling of PVD due to new Kanack treatment (undercoat treatment) *For more details, please refer to the PDF document or feel free to contact us.
