Jul 17, 2019 The effect of time and frequency of the ball milling process on the extrudates were determined. The ball milling frequency was set 20, 30, or 40 Hz and the milling time to 30 min. Then, the milling time was set to 30, 40, and 50 min at milling frequency of 30 Hz. The samples were fed into the extrusion system
Jan 04, 2021 175 rpm is pretty slow for a ball end mill, the SFM at the center is close to nothing and the tool has a hard time removing material and getting it out of the way. It could also be the quality of the 1/4 vs 3/16 cutters, one may be a lot sharper than the other or have better flute geometry. E. Earl Active User. Registered
