Cutting Tools

Low Frequency Vibration (LFV) is Citizen’s widely applicable cutting technology designed to avoid the problem of spiraling chips, entanglement of chips and built-up edges.  In LFV cutting, “air cutting” time prevents the machining temperature from rising, which gives relief from various problems caused by chips and virtually eliminates the need for high pressure coolant.  LFV is ideal for cutting difficult to cut materials in a broad range of shapes (including hard metals and soft plastics).  

Shorter cycle times are key for manufacturers to remain competitive and profitable.  For roughing applications customers can try running higher cutting speeds, taking heavier depths of cut or using higher feedrates to maximize the metal removal rate and shorten cycle times.  However, in finishing applications the depth of cut is usually fixed (1 finish pass) so only the cutting speed or feed can be addressed.  The purpose of this evaluation was to see how CVD-coated cermets compared to PVD-coated and uncoated cermets and CVD-coated carbide when finishing 1045 steel.

Kennametal's five-flute, high-velocity aluminum roughing solid-carbide endmill — the KOR 5 — is said to increase table feed rates up to 66% compared to commonly used three-flute tools. The KOR 5, which is capable of removing large amounts of metal and getting it away from the work zone as quickly as possible, reportedly offers a significant boost in productivity for aircraft manufacturers and their suppliers.

Kennametal debuts two new PCBN insert grades with double-sided inserts for materials up to 65 HRC. The KBH10B and KBH20B PCBN grades are said to deliver high productivity and long tool life when turning tool steels and other hardened materials.

Kennametal's latest addition to its HARVI line of high-performance solid endmills, the HARVI I TE 4-flute solid-carbide endmill features a radical new design. The HARVI I TE is said to deliver outstanding performance in a broad range of materials, including steel, stainless steel, high-temperature alloys and cast iron. And thanks to significantly reduced cutting forces, this tool can be used on any machining center or mill/turn center in the shop.

DoTriple-Mill is Tungaloy’s face milling cutter featuring a dovetail clamping system that dramatically reduces insert lift up and excessive shear force imposed on the screws during heavy duty milling. Three types of inserts fit in the same cutter body, making it the perfect cutter when various materials have to be machined and machine tool settings are limited. A bore type cutter body is available in coarse and close pitch designs, and the standard tool diameter ranges from 2.00" to 6.00" (and in metric sizes 50 to 160 mm).
