ISCAR recently expanded the application range of barrel-shaped endmills with new radial segment sizes. A broad range of “Barrel-Shaped” tools is now available including oval-profile barrel endmills intended for advanced semi-finish and finishing operations of 3D surface applications. The barrel endmills designed with a cutting as a segment of a large-diameter arc, reduce the number of passes and cusp height compared to conventional ball-nose mills and therefore ensure shorter cycle times and superb surface finish. Barrel endmills are ideal for advanced 3D profile milling, especially on 5-axis simultaneous machining operations for parts such as turbine blades, orthopedic implants, molds, impellers and blisks. ISCAR broadens its application range of the oval barrel line with 4 new endmills made of ultra-fine carbide grain IC902, PVD coated with high resistance to abrasive wear. This grade is suitable for machining diverse materials including hardened steel and heat resistant steel.

- gang cutting ( milling)
gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.
- physical vapor deposition ( PVD)
physical vapor deposition ( PVD)
Tool-coating process performed at low temperature (500° C), compared to chemical vapor deposition (1,000° C). Employs electric field to generate necessary heat for depositing coating on a tool’s surface. See CVD, chemical vapor deposition.
