Producers and die & mold shops can eradicate chatter problems in many milling operations with Iscar's unique Chatterfree carbide end mills. The cutters' variable-pitch flute pattern omits harmonic vibration, the central source of chatter. This enables faster cutting and finer finish in rough or finish slotting, shoulder milling and cavity milling. In addition, users also report sustained edge life due to reduced chatter. The chatter-free feature is applicable in both solid carbide endmills and tips in Iscar's Multi-Master replaceable-tip family. Diameter range is 6 to 20mm for the solid carbide endmills, and 8 to 20mm for Multi-Master tips. These completely new endmills are perfect for reduced power machines with ISO40 or BT40 adaptations. The solid carbide version can handle full slot machining up to 2xD. Depth capability on the replaceable-tip version is more constrained since the active length is shorter. In full slotting applications on alloy steel, the solid carbide fabrication surely handles 0.03-0.05 feed rates at 180-220mm/min surface speed and 2xD depth of cut.

Finishred - Ground Breaking Solid Carbide Endmills

Iscar is presenting the EFR.. B44 and the MM EFS.. Finishred a innovative solid carbide end mills family. The Finishred carbide endmill is a consolidation of both roughing and finishing endmills in a single tool. Roughing endmills remove metal from work pieces more promptly and proficiently than traditional endmills. However, roughing endmills leave grooves on the machined surface. In consequence, after using a roughing endmill, a finishing endmill has to be used in order to acquire a smooth surface finish. This demands time-consuming tool change, setup time and inevitably of keeping two endmill types in the inventory.

Qualities of the Finishred Endmills:

The EFR.. B44 and the MM EFS.. endmills feature 4 flutes with 45 degree helix, two serrated flutes and two continuous flutes.

The cutting edges of the finishing flutes are radially farther from the tool axis than the cutting edges of the serrated flutes. The finishing flutes leave out the grooves created by the roughing flutes, leaving a fine surface finish.

The tool is fully competent and facilitates running at rough machining parameters, ending in finish surface quality.

The unique tool design subdues vibration at high load applications.

The tool creates short and long chips simultaneously. This chip mixture is evacuated more readily than each individual chip type, an outstanding solution in slotting and cavity milling applications.

The Finishred is also accessible with the Multi-Master indexable milling head alternative which combines the Finishred includes with the usefulness of little setup time, no regrinding costs and the wide range of shank and extension choices are obtainable for the Multi-Master milling heads.

A single tool combines the roughing and finishing endmills; therefore lowering stock.

Tool change and setup time can be eliminated.

An extra tool position is attained on the machine

New Chip Splitting Solid Carbide Endmills for Increased Metal Removal Rates

ISCAR is introducing the ECP-3/4L family of chip splitting endmills. The radical endmills are available with 3 and four 38 degree flutes in grade IC900. They feature 2xD and long shanks with diminished neck diameter, which facilitate machining along high shoulders, at high feeds. These endmills, due to their chip splitting factor and force distribution can be used very effectively on low power machines (CAT40/BT40/ISO40). The serrated cutting edge incorperates flat peaks which leave a superior surface finish, in association to the current rougher carbide endmills. The ECP endmills are suggested for machining austenitic and martensitic stainless steel, at up to 2xD depth of cut. They can be used on alloyed steel as well. All of the preliminary tests conducted at various customers' locations showed striking results.
