Iscar Metals expanded its Chatterfree solid-carbide fourflute endmill family with the addition of smaller (0.125-in., 0.157-in. and 0.188-in.) and larger (1.00-in.) diameters for roughing and finishing operations. Due to their variable pitch they feature good chatter-dampening ability.
The endmills maximize stock removal rate and reduce cycle time in most milling operations. Their ground geometry provides good surface finish and long tool life, while machining at high materialremoval rates.
The endmills work well with low-power machines with ISO40, BT40 or CAT40 adaptations to improve their material removal rate while eliminating vibration. They can be used for full slot machining of up to two times diameter.
Cutting conditions for rough machining of alloy steel include: cutting speed: 590 to 720 SFM; feed: 0.001-in. to 0.002-in. IPT; depth of cut: two times diameter; width of cut: full slot; flushing method: air, keep the air tube in the direction opposite of the tool’s motion.
Cutting conditions for rough machining of stainless steel include: cutting speed: 328 to 390 SFM; feed: 0.001-in. to 0.002-in. IPT; depth of cut: 1.5 - 2 times diameter; width of cut: full slot; flushing method: emulsion/air.
