Maximum precision and efficiency in finishing and superfinishing

MicrospheroXG ball nose end mills have a radius tolerance of +/– 0.005 mm.

In order to really achieve this high level of precision, a measuring method is required that can measure the entire cutting edge over 180°. The radius is measured at 5° intervals: from 0° to 180°.

This ensures a level of precision that is within tolerance across the entire ball. The shank ground to tolerance zone h5 also significantly reduces the concentricity error and further increases the precision of the component.

Conventional measuring methods, on the other hand, generally measure only from 10° to 80° and from 100° to 170° in order to exclude the difficult- to-grind transitions between the radius and curved cutting edge and the center errors.

When such tools are used on conventional 3-axis machines, steep tapers and even bottom surfaces cannot be finished with sufficient contour accuracy.

The right micro cutter for every application

With the extended MicrospheroXG and MicrotoroXG range, FRAISA offers exactly 219 different options for the precise machining of graphite components – in different lengths and diameters.

Cutting-edge technology for maximum productivity

MicrospheroXG and MicrotoroXG milling tools boast superior performance and component quality thanks to the perfect coordination of the carbide substrate, diamond coating, micro and macro geometry, and an optimized CAM milling strategy. They also offer extremely high process reliability and wear resistance. For example, after four hours

of milling, MicrospheroXG tools show a radius reduction of only 4 μm. Thanks to a wide range of products and a smart assortment structure, it is simple to find the ideal tool for every graphite milling application.
