The challenging requirements of today’s high-tech production equipment demands the provision of 'out of the box' advanced cutting tool solutions. Innovative cutting tools release the latent productive capability of modern machine tools and help to deliver enhanced profits to users.
In order to comply with market demands, Iscar recently exhibited its next generation, indexable drill and further extended its comprehensive product portfolio with the launch of Sumo3Cham – a new three flute indexable drill.
The innovative design of Sumo3Cham is said to raise users’ manufacturing productivity by reducing machining cycle times by up to 50% when compared to the conventional two flute drills, Iscar claims.
The new product’s pocket configuration is constructed on a close structure design with three contact areas based on a dovetail joint. This rigid clamping configuration divides the forces applied to the tools' pocket into three segments, dramatically reducing harmful influences on the pockets’ lives and also substantially prolonging tool life.
In a similar way, the cutting forces are equally divided across the three cutting edges of the drilling head. The application of less pressure to each of the contact surfaces further extends the life cycle of the head.
As the cutting forces are spread across three cutting edges, the drilling process becomes simpler, more stable and the penetration into the component’s material remains more balanced. Thus, users can work up to twice as fast, as the feed per tooth can be increased significantly. Alternatively, users can maintain the same feed per revolution, as with a two flute drill, and achieve much longer tool life.
The Sumo3Cham clamping, which relies on three points of positioning, provides high levels of repeatability when the drilling head is replaced. Three radial and three axial stoppers secure the drilling head and ensure a reliable drilling process in high feed machining environments.
Furthermore, due to its sharp edges and the low axial force it applies, Sumo3Cham is efficient when drilling a through-bore particularly when the drill breaks through a slanted surface; it also creates fewer burrs on exit. Since the material work hardening is low, a reamer or a tap which may be used for a subsequent operation will gain from extended tool life and accomplish improved results. Also, the innovative geometry of the Sumo3Cham self-centring head shapes the produced chips optimally to allow smooth evacuation through the three high helix polished flutes.
Iscar says it maintains its longstanding tradition of designing highly efficient, user-friendly drilling systems. These distinct products eliminate the use of tightening screws to clamp the drilling head in accordance with the company’s motto ‘No Set-up Time’.
Sumo3Cham is now available for machining alloy steel, carbon steel, soft and gummy low carbon steel and cast iron.
