RHINO-FEED ™ HIGH-FEED MILLS RHINO-FEED ™ High-Feed Milling Series FEED What is The ultra-aggressive geometry of RHINO-FEED, DAPRA’s high-feed line, takes advantage of chip thinning to allow feed rates up to 5x faster than normal! Use RHINO-FEED high-feed inserts for: SINGLE-SIDED • old cavity and core roughing M • oughing of complex part contours R • Slotting • 2D contouring • Pocketing • Helical interpolation •FEED F ace milling • Step milling NOTE: High-feed milling does a tremendous amount of work in a short period of time. This line's high production rate can create more heat than typical milling tools. Strong air blast is recommended (multiple lines if possible). RHINO-FEED ™ Options: R2 Mini-Feed Cutters and Inserts • • • • • .500” - 2.000” OD 8mm IC 3 usable edges “D” cutting edge .030” max. DOC R3 Mid-Feed Cutters and Inserts • • • • • 1.000” - 3.000” OD 10mm IC 4 usable edges “T,” “D” or “F” cutting edge .045” max. DOC R4 Heavy-Feed Cutters and Inserts • • • • • 32

.010” actual chip thickness At .050” FPT High-feed milling creates significant chip thinning due to an extreme lead angle. Feed rates must compensate for FEED this to maximize productivity. The figure at left shows an example of this condition. Adjusting feed rates to account for chip thinning creates cutting conditions that provide very high feeds (IPM), but at lighter depths of cut (DOC).

“D” INSERTS Positive cutting geometry designed to reduce cutting forces and heat. Suitable for all materials. T Corner Radius Corner Radius RHINO-FEED ™ HIGH-FEED MILLS * A special corner radius value is required for correct programming of a high-feed insert. Using the program radius avoids gouging of the corners in the workpiece material. The high-feed insert will naturally leave a small amount of extra material at the bottom-most layer of the cut, at the intersection of the wall and pocket floor. See diagram at bottom of this page.

RHINO-FEED ™ HIGH-FEED MILLS Application Information Recommendations • ool is most appropriate for “Z-level” roughing; ramp to T Depth of Cut (DOC) and clear entire level. • olid plunging is not recommended with RHINO-FEED inserts. S Ramping (up to 2° max.) is recommended. • ry to maintain at least 75% of the cutter diameter on the T workpiece whenever possible. Hanging a cutter off to the side of your work is detrimental to tool life and performance. • idth of Cut (WOC) should be 60-75% of cutter diameter W whenever possible. A slight scalloping effect between passes is acceptable. For...
