Need Help!- RPM

[saved]

We recently bought a new Mazak Integrex-e 650 H II. From the factory the spindle was set at 300 RPM max. How can we change this to allow for better surface speed up to 1100 RPM? Thanks.

Call factory...

Did you get a different spindle or something? I think the 650 should be able to go 1600rpm.... or its in the programming....

[MrMazak]

I hope you are the owner of that new machine so when you void your warranty by making your machine "better" than the engineers at Mazak could, you can fire yourself. I don't know what the max rpm is on that machine but you can't simply flip a switch to get more rpm.

Is there anyone who knows these machines and knows how to change the parameters in this area rather then someone who is just beating their gums?

[MrMazak]

There are no parameters to tweak for that!!!! Machines are designed with specific spindles and drives they can't be overclocked like your home computer!!! wow, I can't believe this.

there are so many parameters and so much parameter interrelations. For an end user to teach himself how to change something as elemental as maximum spindle RPM by educated guesses amounts to 'parameter roulette'.

You could have a used or showroom machine that has been tweaked for a "not to exceed" rpm that is much less than maximum possible RPM?

Parameters SA1 through SA8 seem to determine max RPM vs 'gear range', if you want to play parameter roulette. these are listed as "at power on", which means the change is not effected without a reboot.

The current MAZAK install practice is to back up factory parameters VERY THOUGHROUGLY and leave this back up info in a separate directory on the machines hard drive. A copy of this folder is sent to the MAZAK Tech Center for archiving on their network.

I think your solution could be best found by dealing with your local MAZAK Tech Center? MAZAK Techs have a MAZAK inside tech only applet called "parameter compare". So you could make a copy of your parameters as they stand as of right this instant and compare that to the original install parameters. This applet will flag all changes between parameter files, which will pinpoint what may have been changed to make your RPM so slow?

The main point is that there is an absolute specification for your machine on what the max RPM should be. This can possibly be restricted by parameter to make it LOWER, but no way no how should the specified max RPM should ever be changed!

An E machine by it's very nature forces the end user to get to know MAZAK techies. These E Machines are not a two axis 'generic fanuc' type machine! E machines are at the outer limits of modern CNC technology and thus require a tremendous amount of MAZAK specific knowledge to completely master! There is so much capability in an E machine! It's the job of the MAZAK support people to make sure their end users master this wonderful new technology as much as possible - it's the nature of the beast!

There are certain parameters that a MAZAKER must know to be effective. However, this IS NOT ONE OF THEM!

I hope this helps a little for you....

The reason that you cannot believe it is because you don't have a clue about what you are talking about! If YOU will simply shut your mouth and let someone who knows how to change the parameters on this thing all would be much better.

Thank you Jim for the info, unlike some other knuckle heads on this board who simply want to beat their gums.

Wow... what a jackass... but I guess a little bit better description of situation and resolve could've avoided some of that...

So, still curious though... Mazak's factory setting clips you at 300rpm? Are you running one of the optional xtra large chucks? (and BTW, you will void the warranty but that's your choice... just passing it on..)

[MrMazak]

Probably has it in first gear and doesnt know how to change it.

Again you show you ignorance. The 650 changes gears automatically as surface speed dictates higher RPM. We have solved the problem. It was in the parameters.

Great for you! I'm glad you figured it out. Let us know what parameters they were so we all can benefit from your new found knowledge.
