Just revived a brand new Horizontal and I'm looking for some input from people who run similar machines to see if I am asking too much.
For now I'm leaving the brand of machine and dealer out because this in no way is a bash thread.
The machine in question is a 400 horizontal with a 50hp 15k 40 taper dual contact spindle and a fully programmable 4th axis.
The 1st thing I went to do on the machine was to face off my tooling plates. Fairly standard practice for most guys with a new machine. Plates are 1.5" thick 4140 mounted to a standard 4 sided tombstone.
Cutter was a 3" Iscar with .06r. Same tool we haven been using for years in our 40 taper verticals. The machine would buck and sound horrible regardless of the speeds and feed or depth of cut. Finish was always horrible and chattery. Depth of cut was as low as .01 and feed was .003 ipt. I even dropped to a 2" face mill and took a .01 cut on the lowest spot on the tombstone as I could but the finish is still sub par to my standards. I tried with the 4th clamped and unclamped but didn't see much difference in finish. Very slight difference in sound.
Small >1/2" cutters seem fine but I haven't even begun to stretch the load meters. Tech came out and tore everything down and said everything is tight your just asking too much for the machine. I have plenty of experience with 400 sized machines but they were all positional 4th axis.
Am I really expecting too much out of this thing? I don't see how I'm going to be able to use the 50hp. Maybe this is something I have to program around.
Last photo was the 2". 800rpm 10ipm 4fl .01 depth of cut.
