Sandvik Coromant’s new CoroMill Plua HFS end mills for side and pocket milling offer higher performance and security in machining, according to the company.
Today’s modern shops utilize the latest milling strategies, such as trochoidal milling, to enhance productivity and process reliability. Often generated with CAM software, toolpaths for this type of milling provide a constant maximum chip thickness and short arc of contact offering customers high feed rates, minimum vibration and longer tool life. Designed with these strategies in mind, the CoroMill Plura HFS utilizes the complete cutting length of the end mill and achieves a higher metal removal rate with smaller diameters compared to indexable milling and traditional milling strategies. The result is lower tools costs and improved overall productivity.
CoroMill Plura HFS features include:
- an unequal helix flute design that assures a variable angular pitch in every axial section to increase the chatter-free material removal rate.
- an asymmetrical chip-breaker profile that improves chip evacuation and minimizes the risk of edge chipping and tool breakage.
- a conical core shape with a smaller core diameter at the face to improve chip evacuation capabilities, with a larger core diameter at depth of cut maximum (APMX) for maximum stability.
The grade for the CoroMill Plura HFS is the tough GC1740, which was developed to resist bending forces generated when using a 4xDC length of cut. This is especially needed when the component has a large depth of cut and cutting width. Furthermore, Sandvik Coromant’s Tailor Made offer includes CoroMill Plural end mills for manufacturers or machine shops needing a 5xDC length of cut.
