Ball end mills. A popular alternative cutter for engraving in plastic and metal is to use a small ball end mill, something in the range of 1/32". The benefit to a ball end mill is that the lack of a sharp tip makes them very durable and they're typically ground with 24 spiral flutes. The downside is that the engraving may not be quite as sharp ...

For 3D shapes like the yoyo project below, a 1/8" or 1/16" ball end mill produces the smoothest contours. For best results, keep a set of end mills specifically for Delrin and other plastics, and never use them to cut metal or PCBs. This allows for increased milling speeds and a better finish. What are some sample projects? The OtherYo YoYo

PCB designers use soldermask defined pads when following the mm pitch design guidelines. There is a +/ 3mil tolerance for the soldermask layer aperture and very small pitch mil ( mm) as shown in Figure 3 below. Therefore, the very small soldermask (less than 4 5 mil) cannot securely attach and exist between the two pads.

A planetary ball mill consists of a rotating sun disc (SUN), on which one up to four grinding chambers (GC) are located. The grinding chambers themselves rotate at higher speeds, normally in opposite direction to the sun disc to ensure high forces and a highly random motion and collision pattern of grinding media (see Fig. 1)..

The end mill speed is calculated with the following formula: n [rpm] = (vc [m/min] *1000) / * ø d1 [mm]) Example calculation: vc = 500 m/min (selected from chart) d = ø 8 mm 19904 rpm = (500 *1000) / ( * 8) If the maximum speed of the milling motor is lower than the calculated value, the maximum speed of the milling motor needs to be inserted into the formula for the feed calculation.
