Seco Tools offers its MR6 chipbreaker optimized for peak performance in the medium-rough turning of steels. The chipbreaker’s main advantage is the open and highly positive design coupled with the company’s Duratomic coated grades, allowing for the use of higher cutting speeds when compared to traditionally designed chipbreakers, the company says.
The chipbreaker generates low cutting forces within the main cutting area allowing high cutting speed, depth of cut and feed, which increase machine utilization and productivity for the customer. Its low static and dynamic forces are said to make it less prone to vibration, thus increasing reliability, security and part quality. According to the company, the common bumps on traditional chipbreakers for steel turning create fast crater wear at high speeds and feeds, while the open design of MR6 leads to greater economy and more stable production, achieving high levels of throughput.
The chipbreaker is designed for each individual insert with regard to the combination of insert size, shape and geometry of the corner radii, to ensure coverage of as much area as possible. It is suited for medium to rough turning of steels with depths of cut of 0.060" and greater and feed rates from 0.008 to 0.032 ipr.
