Starting Cnc with a MAS MCV 750 - it's a great machine?

[NicholasGurin]

Hello everyone, i'm Nicholas and I came into the world of cnc from January 2017! I have a vertical milling machine, a Mas Kovosvit MCV 750 of 2001. It's like new, only 4500 hour of working.
I started doing something like footpegs for motorbike or bearing cap for my dad's racing engine with Fusion360 but nothing of important.
Is it for you a good machine for work steel or other hard material? The hardest material machined is steel 2311 quenched, with an hardness of 1000 N/mm2. WIth a 50mm face mill I felt enough vibrations.
Do any of you use it?
Thanks for the answers and good chips!


Some specs of machine:

Spindle: 7.5Kw - 20-8000rpm
Feed and travels: 16000mm/min - 750x500x500
20 slots + 1.
Max load on the table: 400kg
Control: Heidenhain 426/430

Welcome !
Great post.

Most here do not have large metalworking cncs, much less with toolchangers.

Please, ..
do me a favour.
Take a piece of stainless, anything, 303, 304, 316, 404, whatever You have at hand.
Ideally, about 10 mm to 20 mm square rod.

Please mill a bit sticking out of the vice, about 1D-, so 10 mm for 10 mm billet, 10-15 mm for 20 mm rod.
As good as possible re: accuracy and surface finish.
I am extremely interested in the real accuracy of the part, your machine can make.

I am happy to pay for the material and postage, EU, (anywhere).
I am happy to measure it, (and post the results (if You agree).)
I am extremely interested in *how accurate * tuned pieces can be done on various machines.

Ideally, 2 pieces "stock" and "tuned" would be best.
I expect that stock pieces vs tuned have some difference in size, 0.001 - 0.010 mm.

Yes hanermo, good idea!
Tomorrow when I will go to my little "shop" I will search some stainless rods. I let you know. If I have the material I will do some tests in the next days and if you are interested I can ship you something.
