6 Flutes Ball End Mill for High-efficiency Finishing Mitsubishi Hitachi Tool Engineering, Ltd. New Product News No.1710E-i

01 6 flutes specification enables finishing 02 03 at feed rate of 20m/min. High-efficiency machining is possible than conventional ball end mills. Use of outer side cutting edge maximizes the tool performance. More effective machining is possible by using 5-axis MC. High accuracy and long tool life Employed original cutting edge geometry which tuned 6 edges finely. High accuracy machining with long tool life is possible since each edge work uniformly even with micro cutting depth. High rigidity design Tool rigidity increased as much as possible in order to suppress the deflection of the tool...

Standard cutting conditions (Finishing) Work High speed cutting conditions (Finishing) Work [Note] © High speed cutting conditions are applicable as long as projection length of 3D or less and work shape that can be followed by high performance MC. @ Since cutting edge is designed even to the tip, it can be used for 3-axis machining. However, in order to allow the 6 flutes to function, please use it by tilting more than 30°. © When machining near the center of the ball-nosed end cutting edge, please adjust the feed speed to about one third. ® ae is a reference value. Please refer to cusp height...

Attentions on Safety 1. Cautions regarding handling (1) When removing the tool from its case (packaging), be careful that the tool does not pop out or is dropped. Be particularly careful regarding contact with the tool flutes. (2) When handling tools with sharp cutting flutes, be careful not to touch the cutting flutes directly with your bare hands. 2. Cautions regarding mounting (1) Before use, check the outside...
