Advice on Replacement CNC's Needed

Aug 13, 2006 4 Replies

Currently I have a Haas VF3 vertical cnc mill with a 4th axis, and a Haas SL30 Big Bore cnc lathe with parts-catcher and tailstock. I am interested to hear from those in the know, what their suggestions for replacement would be or if i should bother thinking of replacement. I machine a lot of different things from agricultural impliment stuff, to land-scraping machine parts, to oilfield and small automotive custom parts. i guess i kind of do it all. My VF3 is only about 2 1/2 years old with no crashes and in mint shape but only does 7500 rpm. My SL30 has been rebuilt once about 4 years ago from a crash, is about 6 years old and only does 2400 rpm but does just have the capacity to do a 16" tire rim and has a 4 1/2" drawtube.



Any suggestions would be great.

Do you know WHY you want to replace them? The 7500 prm limitation is important if you are cutting aluminum 20 hours a week or more. Otherwise, they are making money, why waste the profits on the newest machinery if you are not into high volume production? The purpose of running the business is to maximise the profits you can. Replacing a machine for "esthetics" is poor business sense. Otherwise, what spefically needs upgrading? Pete

Exactly what Pete said. Make up a P/L sheet to show how the new machines will make you more money bottom line compared to the existing machinery. I run old machinery. To replace the stuff with late model equipment would be a waste since most of the time involved is setup which would not change much with a new machine. I am though thinking of live tooling on my vbm which would be a considerable savings in second op drilling and tapping.

How much time do these machines sit idle during your working hours?
