This translates into fewer inserts per operation, fewer inserts kept in inventory, lower cost per cutting edge and improved operator efficiency due to fewer tool changes.
Joachim Koller, responsible for technical service at Seco says: "Because of the round insert, the cutting edge has a larger radius, which in turn allows higher feedrates.
Tool cost was also greatly reduced thanks to the longer cutting edge and the fact that on the round inserts we can use up to 20 edges, not just the 14 that Seco promised.
Gerhard Huber, Seco's sales and customer care manager, sums it up: "The extremely stable cutting edge of the round insert is the key to success in terms of productivity.
When cutting edges overlap each other, the resultant cutting forces are lower, the tools are always under load, stability is improved, vibration is reduced and the required machine power during the milling operation is lowered.
Clamping the inserts on heavy-duty cutters with multiple inserts provides full-effective helical cutting edges and the possibility to machine at large depths.
New octagonal inserts (shown at right) offer eight cutting edges, each with 45-degree lead angles, for more economical milling applications.
Inserts combining helical cutting edges, a large axial angle, and a rib-type rake face design offer a self-balanced, stable tool for cost reduction and high performance in semi-finishing and finishing.
This twisted geometry doubles the number of cutting edges of deep face grooving tools.
A unique twist in the insert geometry doubles the number of cutting edges for deep cutoff tools.
Ernst and Merchant in 1941 provided the world with the first quantitative analysis of metalcutting by their famous equation of the forces at the cutting edge.
Insert cutting edges may be positioned relative to both radial and axial planes in either positive, neutral, or negative rakes.
The double-negative insert allows the strongest possible cutting edges, able to withstand heavy chiploads and high cutting forces.
Negative radial rake provides strong cutting edges, while positive rake creates a shearing action.
