Dti Suggestions For Newbie

We ran 11,000 aluminum parts through that mill in Feb. of this year, 1 1/2" 6061 aluminum rounds 1 1/2" l0ng, one end had a 1/4" wide X 7/8" deep slot across the center 1/4-20 X 1/2" deep tapped hole in the other end. Six parts in V fixtures in 3 vices. Face mill to square the ends, . ran 020 X .020 chamfer around each part. The end mill Manufacturer recomended that we run the slotting OP at 17.000 rpm, 165 IPM feed rate. This mill has a max 10,000 RPM spindle, it worked yet was slow and made a lot of noise

It's a different world!

.0005" is a good accuracy with a .030 plus minus swing interapid is a very good tool. Ive have found these at pawn shops for good prices, make sure it works by running it through its paces slowly gently andwatch for sticking and a return to zero. slam it a couple of times and watch for zero return (not too hard) bill
