	The Warco mill can be used to machine objects from a wide range of materials. Training is required before members use the equipment because it is easy for users to damage it, and serious injuries, or fatalities, are possible. The machine has a table 660 x 152mm that can move 37cm in the X direction, 15cm in the Y and 34cm in the Z direction.		The Warco mill can be used to machine objects from a wide range of materials.

-Use a conventional milling cut to get the part to approximately the final size. With a conventional cut the cutting surface and the work piece are moved in opposite directions. A climbing cut is where the cutting surface and the work piece are moved in the same direction. It produces a better finish but puts extra strain on the cutting tool. Therefore only use climbing cuts for light finishing cuts to leave a smooth finish.
+Use a conventional milling cut to get the part to approximately the final size. With a conventional cut the cutting surface and the work piece are moved in opposite directions. A climbing cut is where the cutting surface and the work piece are moved in the same direction. It produces a better finish but puts extra strain on the cutting tool AND IS MORE LIKELY TO BITE, TAKE UP THE BACKLASH, BITE FURTHER AND BREAK THINGS. Therefore only use conventional (opposing directions) cutting.  (Climb cuts are only to be used for very small finishing pass operations, usually not in steel, where tool biting is not a concern).
-When drilling, start with a centre drill to make sure that the hole starts exactly centre. It is usually OK to drill to a depth of 3 to 4 diameters in a single pass. After that withdraw the drill ever diameter of cutting depth to clear the swarf. Use cutting fluid beyond a depth of about 2 diameters. Be aware that halving the diameter of a drill reduces its strength 8 fold. Small drills break very easily and broken tools present a hazard. Much much less pressure is needed to drill small diameter holes. Use just enough pressure to create long curly chips. Look up the appropriate rotation speed for the drill. The Warco cannot spin fast enough for drills below about 2mm. For these, use our Sherline Mill.
+When drilling, start with a spotting drill (centre drill at a push) to make sure that the hole starts exactly centre. It is usually OK to drill to a depth of 3 to 4 diameters in a single pass (less with a centre drill). After that withdraw the drill every diameter of cutting depth to clear the swarf. Use cutting fluid beyond a depth of about 2 diameters (and always in steel). Be aware that halving the diameter of a drill reduces its strength 8 fold. Small drills break very easily and broken tools present a hazard and are exceptionally difficult to remove. Much much less pressure is needed to drill small diameter holes. Use just enough pressure to create long curly chips. Look up the appropriate rotation speed for the drill. The Warco cannot spin fast enough for drills below about 2mm.
