BALL END MILLING TOOLS
Clearance at Ball End Milling Tool
When radius is 0,5mm or larger, Contour will adjust the diamond height and clearances so that the diamond will fit in its own cut profile.
When radius is smaller than 0,5mm it is not possible to reduce the diamond height so that it will fit in it's own cut profile. Milling tools with smaller radius than 0,5mm can be supplied, but then cutting depth is reduced to 0,19xR
ALIGNMENT OF BALL END MILLING TOOLS
The position of the ball end milling cutter is of main importance. Contour Fine Tooling can guarantee the position of the cutting point being within 0,02mm of rotation axies as well as in height as lateral position. Best option is to calibrate the machine for the best results. If this calibration cannot be done, a distortion will occur in the center as shown in the diagram below
