ELMAX / 59HRC
SSPB220 / CBN Super Spiral Ball End Mill
Work size 30×30×30mm
Material : ELMAX 59HRC
Cutting time: 3hr 25min.
SSPB220 realized high quality surface by spiral ball shape to improve sharpness of cutting edge, and by back-taper shape which reduce the influence of vibration.
•Adopted spiral ball shape to improve sharpness of cutting edge.
•Adopted cutting edge shape to improve the chipping resistance of cutting edge.
•When peripheral cutting edge makes contact with cutting surface, vibration occurs by an increase in cutting resistance and it affects tool life and cutting surface quality. The influence can be reduced by adoption of the strong back taper shape.
•Enlarged standard tool size up to R3 to extend application range.
•MUGEN-COATING PREMIUM for hardened steels and unique new design excel in chipping prevention and resolves chattering to realize excellent finished surface.
•Applicable for hardened steels up to 68HRC.
•Total 190 sizes!
