do you have air? don't liston to Toby he only shows how little he knows about machining (on a Tormach)...by dropping RPM you increase tool and spindle load and build up heat in both. A-series will work harden real fast...you will want a shallow depth of cut and and fairly fast feed ...you can place a piece of plywood for a sheild (plix will just melt with hot chips)... |
