INDEXABLE MILLING CUTTER WITH PRECISE COOLANT STREAMS
Last updated:
Abstract:
An indexable milling cutter includes a milling cutter body with a plurality of flutes and a plurality of seating surfaces adapted to mount a cutting insert thereon. The milling cutter body includes a plurality of coolant reservoirs in fluid communication with an adapter. In one aspect, each coolant reservoir lies along a circular intersection line of a coolant manifold. In another aspect, a longitudinal axis of each coolant reservoir is oriented at a non-zero angle, A, with respect to a central, longitudinal axis of the milling cutter. A plurality of coolant ducts in fluid communication with each coolant reservoir, each coolant duct having a smaller cross-sectional area than the coolant reservoir, provide multiple streams of coolant targeted at a plurality of specific critical cutting areas of the cutting insert.
