Milling Cutters

Anyone who’s replaced a head gasket on an internal combustion engine knows a smooth, flat surface on both cylinder head and block is needed for proper operation. No one understands this better than automakers, who strive for predictable, controlled surface finishes and high production output, together with maximum tool life and the lowest tooling cost per machined component.

A high-feed milling cutter for diameters 13–25 mm and 0.500–1.000 inches has been introduced by Sandvik Coromant. Among the advantages of using the new CoroMill 415 are enhanced security, thanks to iLock insert seat interface technology, and high metal-removal rates as a result of high cutter density and high feed capacity.

Tungaloy Corp. introduces TungTri-Shred, a new shoulder milling cutter for highly productive machining. With today’s dramatic growth in the performance of machine tools, high-speed machining is often the first choice for manufacturers.

Tungaloy Corp. offers TungForce-Rec, the indexable miniature shoulder milling cutter. The TungForce-Rec insert has a unique V-shaped bottom to enhance the insert’s resistance to centrifugal force, assuring reliability and high productivity during high-speed machining, according to the company.

Tungaloy Corp. offers MillQuadFeed, a new high-feed milling cutter. With a depth of cut up to 0.098” (2.5mm) and a feed rate up to 0.078” (2.0mm) per tooth, MillQuadFeed accomplishes astounding metal-removal rates in rough milling operation, according to the company.

DoTwistBall from Tungaloy America is an ideal tool for die and mold, as well as general engineering. Combined with a rigid clamping mechanism, the insert’s unique twisted shape improves chip evacuation for stable machining and long tool life in roughing operations.

DoTriple-Mill is Tungaloy’s latest facemilling cutter, featuring an innovative dovetail clamping system that will reportedly dramatically reduce insert lift up and excessive shear force imposed on the screws during heavy-duty milling. Compared with the last generation of facemilling platforms, DoTriple-Mill delivers stable machining and consistent tool life.

DoMini-Mill is a copy mill developed for semifinishing operations, featuring Tungaloy’s latest H-class insert. The economical six-cornered insert with dovetail clamp technology has a double-sided geometry, yet positive flanks, providing sharpness and high cutting edge strength simultaneously.

DoForce-Tri from Tungaloy America accepts a double-sided insert with six cutting edges. Three types of inserts are available to meet the needs of many different jobs: a standard wiper insert with an MJ chipbreaker on true 90-degree cutting edges or with an NMJ chipbreaker on serrated cutting edges, as well as a radius insert with an MJ chipbreaker on large round corners for edge toughness instead of wipers.

WS40PM’s cobalt-rich substrate provides robust fatigue resistance and edge integrity, while the multiphase AlTiN-TiN PVD coating reduces tool wear, making it suitable for a range of high-temp steel alloys, austenitic and PH stainless steels, nickel-based superalloys such as Hastelloy and Nitronic, and titanium.
