CNC Cookbook Milling Machine Home Page

I was curious to see how much better the finish could be with this end mill so I cranked the Y-axis slightly so I would be cutting just the far wall and making a slightly wider slot Given where the wall was and the direction I was going this was conventional not climb milling so the finish is supposedly better if I had gone the other direction and climb milled Get price Get Price
