Scandia Tools AB (Gothenburg, Sweden)
Industry: Manufacturing of Cutting Tools & Inserts
Challenge: Efficiently and accurately producing the complex coolant holes on the sides of solid carbide indexable inserts. Their laser drilling was precise but slow, and EDM was too expensive for high-volume lines.
Online Discovery: Their production manager found our company at the virtual EMO Hannover fair, where we presented a broaching solution for carbide.
Initial Contact & Virtual Meeting: This was a highly specialized application. We shared videos and micrographs of broached carbide surfaces, demonstrating the edge integrity and surface quality achievable.
Site Visit: Their technicians were most interested in the machine’s rigidity and vibration damping, which are critical for broaching brittle materials like carbide. We demonstrated the machine’s stability with a live broaching test on a tungsten carbide blank.
Purchase Decision: They invested in High-Rigidity Vertical Broach with a special fixture for holding small, delicate inserts. The machine’s exceptional stability ensured it could handle the hard material without micro-chipping.
Usage & Feedback: “Broaching has proven to be the most cost-effective method for forming these coolant holes. The process is fast, and the consistency between inserts is perfect, which is crucial for tool performance. The machine is incredibly robust and requires very little maintenance. It has streamlined this stage of our production remarkably.”
