Cutting Tools Round indexable milling inserts allow for low cutting forces
They also include 12 edges to reduce costs, the supplier says.
Kennametal introduces the Rodeka series of inserts for indexable milling. According to Kennametal, the round, double-sided inserts have a unique design with twelve cutting edges for a more productive and cost-effective cutting process. The company added that the anti-rotation feature on the inserts provides stability for higher feed rates and cutting forces with an easy-to-index insert in the pocket.
The three variable topography styles of Rodeka inserts feature robust cutting edges capable of covering any type of component and application, the company said. This design is said to help achieve low cutting forces while at the same time consuming less power. The higher clearance of the bodies permits pocketing, profiling and 5-axis machining, the supplier noted.
Each insert is marked in a manner said to allow the user to easily identify the insert topography and edge number for correct indexing in the tool pocket. For correct indexing, Kennametal explained, the dimple in the edge of each number should be aligned with the groove in the cutter. To keep a fresh cutting edge and maintain top performance, these inserts should be rotated counter-clockwise, according to the company.
Although an insufficient negative clearance angle limits the ramping capabilities of Rodeka inserts, Kennametal said that they are capable of taking on pocketing, profiling, face milling, and blade machining at high metal removal rates with long tool life. Rodeka is available in a range of cutter styles and diameter sizes, including a 32 mm to 42 mm diameter screw-on option, a 32 mm diameter Weldon style, 32 mm cylindrical shank end mills, and shell mill cutters from 40 mm to 100 mm in diameter.
