We are starting to produce AR-15 billet uppers and lowers. We are planning to buy an additional 5 axis machine. The machines we are currently considering are a Mori DMU 50 3rd generation and Matsuura MX-520.

Both would be outfitted with 20K spindles, TSC, 60 tool magazines and laser tool height measuring.

Down the road we plan to automate and run 24-7. To that end, I'd be interested in hearing your experiences with both machines, support, reliability, accuracy and performance or anything else that might be helpful.


Thanks in advance.

neither. GF Mill E 500/700. depending on if you wanna do them one at a time or 3 at a time on a pyramid. doing exactly that with our mill e 700u right now.
 
The round fixture is 2 ops the square fixture is 3 but is a lot faster it will do 144 per day the round about 85

that was a total bitch to squeeze into our GF. the tool barely clears in the carousel, by like .08" after shaving 1/2" off the holder and 3/8" off the drill shank, lol

nice, i'm doing basically same thing as you with the round fixture. 1 hr per fixture of 3 for 1st op. 10 min for second op in 3 axis per part.
 
The 1000 with the round fixture does op 1 and 2 by itself does about 85 per day The 1000 with the square fixture does 144 per day with a vf3 running with it. It takes a little more labor to run. We do a lot of probing to account for the forgings that vary in width.
