visual demo of things I do

Ok people have asked what machining is and it is kind of hard to explain if you have never seen it sooooooo...............

for this job that I am currently working on we start with a piece of aluminum bar stock 2 inches by 4 inches cut to 8.25 inches long




















the ends are faced so the piece is now 8 inches long overall, you can see the endmill in the shower of coolant cutting the fare face of the piece















Now some set screw holes are drilled in which I tap later




















the piece is turned so it is now standing and hole is bored into it at just under 1.25 inches. It is drilled half way from one side then flipped and the other half is drilled from the other side















The hole is then reamed to exact size. when one needs a precision hole, reamer are a very efficient way of doing it















the contouring starts with that big 4 inch face mill you see back there sending coolant all over the place. it is spinning at 4500 rpm at this point
















the piece after contouring , you can see how much material has been removed and there is still one more operation to be done but not today.
