Successfully increasing spindle speeds on TM1

Who here has successfully increased the spindle speed on their TM1 and has been running it like that for a while?

Please let me know,


Also, is it still possible to increase the spindle speed on a newer HAAS?

I cannot answer for the newer Haas machines but on the TM1s from a few years ago the speed could be taken up to 6000rpm; not really surprising since it is the same spindle as the MiniMill which comes out of the factory set at 6000rpm.

My 2013 TM1-P has a 6k spindle. The open ones just need the parameters changed to jump from 4500 to 6k. How to do it is a different story, sorry I cant be of more help on that.

Haas had to limit the spindle speed to 4K RPM on open mahcines because of safety issues. I was told that someone in Europe complained about "what if someone has his hand stuck in the cone where the chip auger dumps the chips"... Heck if someone places his hand there:
1) They won't reach the chip auger
2) They're too stupid to even try
I swear some of these nuckle heads are the reason why we have such stupid laws.

Forgive my ranting... but back to your question, I would ask one of the Haas technicians if you happen to know one. I don't know how it's done but I've heard it can be done.

Here you are copied from another forum:

There are two parameters that you will need to change to increase your spindle speed:

131-MAX SPINDLE RPM

183-Sp MAX FREQ

(PAR 183= MAX SPINDLE SPEED / 3 * 10)

So for 6000 RPM:

131 = 6000
183 = 20000

so what do you think about making a one spin 8k???

I have done it on a MiniMill, not a TM. They will spin at 8000 rpm but take a long time to get there and don't really sound happy. I didn't even try taking any cuts. Since doing that I have obtained a graph showing the torque curve for the MiniMill & TM spindle and at 6000 rpm they only have about 2-1/2 lb-ft. I think at 8000 probably the usable torque is pushing close to zero.

I"ve increased my speed from 4k to 6k and have used 6k quite a lot. About 50% of the time and it is still working fine. I did modify the warm up routine and use it when it asks. If I just start up cold (never lower than 62 degrees), I do a manual spindle warm up on the first part by starting the part with the spindle at let's say 40% and increasing it as I get ready to run. The aforementioned instructions look correct. Just watch out and be careful. Depending on the crash, 4K would be just as bad as 6K.

so how do you change the parameters?

I think taking a 6k spindle to 8k would make a big difference in feed and speeds..and hwo much faster you could make parts.. and the spindle would not be hurt over it.

Did you get your spindle up to 6k?

was told today that the new spindles and replacement spindles in and for the tm1p's are 8k spindles anyway and they it could be reprogrammed to run 7.5 or 8k and to contact my salesman for a price..

anyone that has done this please contact me so i can be educated

Bummer no answer for the 8k spindle increase yet.

Run mine at 6K about 90% of the time.

Increase the rapids too....that will also save time.

How do you increase the rapid speed? Mine will only run at 25% when tool changing and I'd like to increase that as it uses lots of time and air.

Those of you that changes the two parameters, is rigid tapping effected?

No, my ridged tapping is the same as before.

I've been running my TM-1 2007 model at 6K for over a year now when using smaller cutters. No problem at all.
A friend of mine who is a lot smarter than me, changed the parameters per instructions I found here I think it was. I was too chicken to mess with it!

I upped my spindle to 6K and rapids to 400 ipm about 3 years ago, and it works perfectly. As far as how, a very helpful gentlemen took the time to email me the step by step. Here is the text from that email:

First off, you really need to do both mods. Rapids are fabulous, but you
need the ability to turn carbide faster when necessary. These machines
don't make a lot of torque at high rpms, but they are great up to .5" cutter
diameter, so be prepared to learn to carve rather than hog. I do run at
6000 occasionally, but I frequently run between 4500 and 5500 with up to .5"
cutter on soft alloys and plastics. For the rpm mod, follow this
recipe...and remember to slowly let the machine ramp up over half a day or
so...bumping it up occasionally, before you run at higher rpms so that you
properly break in the bearings at that speed. The tm1-p is the same spindle
and runs at 6k, but there is the same break in process when it lands on your
floor. I usually start by hitting mdi, typing in 1000 and hitting spindle
cw button. Then every once in a while, increase spindle rpm by 10%.
Anyway, I have been running at these speeds for a few years with no problem,
so don't be afraid. Also, every day that you intend to let your spindle run
in the upper rpm's, remember to let the machine warm up properly and watch
your spindle load. Recipe for rpm is :

You first have to unlock the Parameters to do this.
1) Press Emergency stop
2) Press the SETNG/GRAPH key
3) Type 7 the push the down arrow
4) Use the Left or Right Arrow to change to off.
5) When off is shown press Write/Enter


Then follow these steps

1) Press Param/Dgnos
2) Enter 131
3) Press down Arrow
4) Change parameter 131 from 4000 to 6000 and press Writr/Enter
5) Enter 183
6) Press down arrow
7) Change parameter 183 from what it is to 20000, mine was 13333, and press
Write/Enter



Now that you know how to unlock and find parameters, this is the rapid mod :


Turn the parameter lock off and change the max speed for all three axis by
TWICE its current setting. The parameters are listed under 'X PARAM A', 'Y
PARAM A' and 'Z PARAM A'. The factory setting for each axis was 462394 which
equals 5.1 meters/minute. Change them to 924788 and that will equal 10.2
meters/minute. 10.2 meters times 39.37 inches/meter equals 401.574 inches
per minute. Piter also changed the acceleration two fold, and while that
might make the machine a little faster, my thoughts were that it would be an
unnecessary amount of extra force on the thrust bearings that wouldn't be
worth the extra second or two it saved per cycle. I left the acceleration at
3000000. This mod was extremely simple and to me just as important as the
max rpm mod. Just remember to back the rapid down when testing a new
program.....I generally use 25% when trying out a new one. You will LOVE
your new tool change speed. Feel free to ask anything else.

Hi, Thanks so much for sharing this. I have already increased the spindle to 6000. I will look into this today or next week and reply back. Does your TM1 have any kind of enclosure or just the pan around the table? Mine has the pan around the table but I modified it to contain and drain coolant much better.

Hi Prototyper, I checked the max speed on my machine is 3699149, not 462394. Any ideas? Should I double that number? My machine is one of the last TM1's made with no enclosure. Thanks
