slow spindle

[Elad]

Hi

 

We need a faster spindle.

Our fastest spindle has 8000 rpm and it is not enough for engraving.

Buying a new spindle is not an option,it cost a lot.

What is the best way to make our spindle faster and what are the prices??how does it work with tool change??

 

Thanks,

Elad, why is your 8000 RPM spindle not capable of handling your engraving needs We sometimes use our 5000 RPM spindle to do engraving on O1 and A2 steels.

We looked at some air-motor spindle increasers last year that are pretty inexpensive (vs a new spindle) but I don't remember any that would go through a tool changer.

i do my engraving and phono finish at 3,500 maximun rpm on the horizontal matsuura and cincinati milacron and works fine ,i mean slower than the haas vf6 that runs at 10,000 rpm but does the job.

Hi ,Elad!

I`ve done engaving with 3900 with Okuma5000v with geared spindel .Now I do it on 8000 on deckel -maho dmc63v and will do it on 15000 rpm if I`ll have.

All the secret is good proportion between rpm and feed and a good cutter,

I prefere to do cutters myself smthn like pyramid with 4 sides.

Works good and fast enough on steel and copper.

And for engaving and milling you can find end mills starting from 0.25-0.3 mm .I use them when angle is not allowed.

Regarding various accelerators many of them nonreliable .

Thanks everybody for the replies.

i did engraving letters at 8000 rpm and at the first 2-4 parts it looked great,but then the cutter finished.

I was told that i need a minimum 15,000 rpm for engraving if i want the cutter to work more then 5 minutes in the material.

my depth cuts was 0.2 mm in aluminum,with 8000 rpm and F200.
