CNC Lathe Cutting Small Threads | |
We are trying to cut a 3/8-16 thread 1-1/4" long in 1018 steel using an Iscar insert and a Mazak QT-10 lathe. We can only go to 95 SFM without a program error (not enough acceleration distance) but that is really leaving a terrible surface finish. We tried a number of things, even making up to 20 passes but it always yields the same results. Does anyone have any suggestions?
Thank you,
Jason |
