Setting Cutting Tool Inserts
Press the Mill button. Travel the spindle base approximately to the center of the main base.
Turn off all power to machine before proceeding.
Remove vacuum housing from chip shield. Attach a dial runout indicator to a cylinder head or engine
block, etc.
Rotate cutter head and check to see that both inserts are the same distance from the center of the
spindle, within .004. If adjustment is necessary loosen the tool holder clamp wedge, and the height
adjustment screw. Move tool in or out the required distance. Tighten the clamp wedge. Snug up the height
adjustment screw. There is a set screw located at the bottom of the toolholder, it locks a dowel pin in
place. When the in-out adjustment is set, loosen the set screw, the pin will pop out and hit the back of the
slot. Tighten the set screw. This way, when a tool holder is removed and then replaced, it will be located
very nearly where it was. Insert height will still need to be adjusted.
Rotate cutter head and check to see that both inserts are the same height within .0015-.0003. If
adjustment is necessary loosen the tool holder clamp wedge, then alternately loosen and tighten the
height adjusting screw and the retaining screw, until both inserts are set as desired. Retighten the tool
holder clamp wedge, and recheck both inserts.
Production Cutting
Aluminum & Cast Iron
For fast tooling set-up, this machine can be set-up with one cast iron cutting insert and one aluminum
cutting insert. Set the cast iron insert with no down or out adjustment. Set the aluminum style insert .02
further out and .005 lower than the first insert. With the cutter head set up this way, aluminum work can
be easily cut. To cut cast iron simply remove the aluminum cutting insert from its holder.
