Got another toy last week. A Nikken NX5 Spindle speeder. Real nice condition in the box with the positioning block and even fit the taper of my mill. Only bad thing was the unit is an older model (Over 4-5 years old) and Nikken changed the design of the SK-10 Slim Chuck collets. The new ones need to be modified to work. The thing is supposed to have less than 10 microns runout a 4x diameter. I paid 299 on ebay.

And heres what I did with it today. Had a job cutting out holes in project boxes for the movie company I have been making parts for. Did the drawings last night, the company just gave me boards and parts and left it to me to figure out where to put everything.

With the spindle speeder running at 20000 RPM I could get about 19IPM, .040 DOC with a 2 flute, 3/32 carbide end mill before I would start loading up.

While the machine was in cycle I got the VFD in the surface grinder wired and installed in the base.

Nice to see someone else serving the industry! I was making things for TV news operations in the neighborhood and made out very well. That's how my complete woodworking shop paid for itself. Also paid for most of my metal shop. If I'd have had your tech savvy with CNC I'd could have been a contender :D

Looks good,those speeders I have seen a few go cheap at auction,but they always had a spindle mount different for anything I have.Last one was about a year ago,it only brought $150.

They are some sort of lighting controller. I had to cut holes in the supplied boxes for fans, dip switch access, binding post, terminal strips, fuse holders, etc. Ended up drilling the vent holes with a centerdrill. Had a hard time holding the case so they wouldn't move around.

Archie, the vise is from that Stevens tooling setup I got about a month ago. Really nice stuff. Each of those vises are about a grand new. The plate under is about three. Needless to say I didn't pay that much, but is has already paid for itself.

Back when my machine still had a R8 spindle I almost bought one of the volstro spindle speeders but I found out they are only good for a low duty cycle. These nikkens can be run continuously. Luckily this one had the BT30 version of 30 taper that all of my other tool holders are.

Btw - going from R8 to 30 taper was one of the best decisions I made for my mill!

Here is the original thread where I bought the vises:

I changed the spindle in my mill from a R8 to a 30 Taper. Got a new one from Supermax for less than $300. I can use any 30 taper tooling, NMTB, BT, CAT. Only difference really is the drawbar. CAT and BT are designed for tool changer usage so they have the V and are a bit shorter than NMTB. Also BT uses metric threads in the pull stud end. I think 12mm. I just use a drawbar. Works great.

That really is a nice unit macona - congrats on getting it as you did and thanks for showing it at work!!!

Nice job, tooling and set-up too.

That really does solve a lot of problems for those wanting high/er speeds without the drama of upgrading spindles and drives etc.

I'd love to see one with an MT3 spigot - some hope!!!

Macona, thanks for the info..... I can add another "thing" to my "hunt list"
I have 3 machines that are NMTB-30 and as far as I am concerened It is the only way to go. 300 sounds like a steal on the spindle. maybe they had a bunch that no one wanted. :D

Happy Hunting
