CUTTING INSERT WITH AN ASTRAL RECESS FOR RECIEVING THE CLAMP |
摘要 |
<p>A cutting insert includes a body that forms top and bottom surfaces, and a center hole intersecting at least the top surface (e.g., a through-hole). A portion of the top surface which extends around the center hole includes an array of projections radiating laterally outwardly around the center hole. A distal end of each projection disposed farthest from the center hole defines a tip of the projection. The projections form at least six tips spaced circumferentially apart. Each tip has a planar top face. A clamp has flat contact surfaces which press downwardly against the planar top faces of respective projections simultaneously as the clamp pulls the insert against an upstanding support surface.</p> |
