New to machining, but the learning is great fun. So I'm running my shiney new HF X2 on my first milling project, a set of clamps to hold down small parts for CMM inspection at work. Milling an inside radius with a 1/2" end mill, on a 5" x 1" x 2.5" block of 6061. Near side goes very well with good finishes. Sound on the opposite side seems a little different. Its the demonstrated lesson in conventional vs climb milling: Spinning along at about a half inch deep, and then the backlash gets pulled into the endmill, which attempts to take a .120 cut. Snap. Hmm, motor's running, but the spindle's not turning. Long story short, the plastic gear that runs off the motor gear is in 14 pieces. Sorry guys, you tried to warn me that this can/will happen, but apparently I needed a demonstration.:whiteflag:
Not a big problem, because two days before I pulled this stunt I had ordered the belt drive conversion from LMS. Lesson learned, humor survives. The material is still ok because the damage is in an area soon to become swarf.
