Pretty much info on both those subjects would be greatly appreciated. basically im trying to work my self up into a career status rather than just a job. hopefully by looking for and finding out this info i could possibly boost producivity and prove im more than just a back. Our current running specs are 18000 rpm 450 in per min using her saff insert routing bits and onsrud 63-725 sinle o upcut. Not sure ,this mite be the the most output that can be given for acm to achieve a good finish. please any advice or conversatoin on this matter is greatly appreciated. thank you |

| Well, I hope I can help you out. In my set-up I use a 63-717 bit from onsrud to trim out parts. Its a 3/16 single flute spiral upcut which runs at 14000rpm and 120 in/min. For 4mm ACM I cut at a depth of .158 in. For V-grooves I use a 37-72 bit, also from onsrud, running at 14000 rpm and 360 in/min. For this one I use a depth of 0.118 in. I've found that this leaves enough plastic at the bottom of the groove to keep the corners from becoming brittle. To get these numbers I used a feed and speed calculator with a chip load of about 0.012. This chip load seems to disperse heat adequately for continuous running on a 10 hour shift. Tool life is exceptional, the 63-717 I can usually keep for upwards of 400 hours, and the 37-72 for even more than that. |
