Taper ball end mill specifically for plastic mold reinforcing ribs Epoch Combination Rib Ball

A new processing method to change the common practice of rib grooving. From discharge machining to cutting machining Features of ECRB-PN Direct cutting using a new machining method Reciprocating cutting with high accuracy Optimum flute shape for high performance Combination of PN coating and optimum base material provides long tool life. By using various combinations from the small lineup of Epoch Combination Rib Balls, a variety of rib sizes can be handled, enabling machining of rib grooves with good release. Cutting machining can replace discharge machining in the region conventionally performed...

Features of flute shape Features of flute shape 1 • The R flute cross-section has the proper shape to provide both rigidity and good chip removal characteristics. • Achieves high-performance cutting with 2-flute tip and 4-flute periphery. Poor chip removal 2 flutes on ball section Figure: Cross-section of R45° portion (R0.4) Features of flute shape 2 Flute groove ・The periphery flutes employ a 2-stage flank surface to ensure flute tip rigidity and achieve good surface roughness in high-performance cutting. 2nd flank face Flank face Coating Improved wear resistance New coating with amazing adhesion...

Combination rib machining can combine the process for machining the top surface width and the process for machining the bottom width. [[Ex.] Shape to be machined) 0.9mm • : Stocked Items. ^Slight differences in the angle of the taper surface of completed rib grooves may occur. Whether or not they will be a problem should be checked beforehand. For making the rib groove shown at right with a top surface width of 1.0 mm and bottom width of 0.8 mm, the following four items should be used. Item code • : Stocked Items. For making the rib groove shown at right with a top surface width of 1.2 mm and...

high accuracy rib grooving. Example of program creation method Machining shape Reciprocating cutting matching Top surface with: 1 mm Bottom width: 0.8mm Depth: 7 to 11.5 mm Situation in which the top surface and rib bottom are curved so that the rib groove depth is not uniform. Reciprocating cutting matching the curved surface of the top surface (Tool diameter: 0.8 mm; Large edge diameter: 1.0 mm; Flute length: 6 mm) Perform reciprocating cutting using a contour that matches the curved surface of the top surface. By performing machining to the depth of the flute length (6.0 mm), the top surface...

[Note] ©Adjust the cutting depth referring to the depth of cut ratio. ©Use the appropriate coolant for the work material and machining shape. ©These Recommended Cutting Conditions indicate only the rule of a thumb for the cutting conditions. In actual machining, the condition should be adjusted according to the machining shape, purpose and the machine type. ©If the rotation speed of the machine does not match the values in the table, adjust the rotation speed and feed rate using the same ratio. ©When machining a tapered surface of greater than 5°, make adjustments such as reducing the

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...
