Upgraded to Real spindle So Porter Cable is For Sale

[wcarrothers1]

Hello..

I know a lot of people ask the question about where to get a real spindle ect ect.....

Well hopefully I will be able to shed some light on that subject in some threads soon as I have upgraded to a real spindle. (see pics of real spindle..)

Will post details on the install in future threads.

But that means my Porter cable is now able to find a new home.

Anyway offering it to CNC zoners as I'm sure there are plenty looking for a good one around here. Else it will eventually hit ebay I suppose.

would come to a cnczoner with the following.


Porter Cable 7518 3.25 hp variable speed router
Wrenches & Porter cable Collets 1/4", 3/8" and 1/2"

Actual Quick route to Porter cable adapter.
7 - 1/2" quick route holders
3 - 1/4" quick route holders

And the items that might interest a CNC zoner the most...

2 cut aluminum router clamp plates for mounting the PC to a gantry
and the dust shroud that matches the plates.

the clamp plates have 3 - 1/4-20 threaded holes in the back for bolting to gantry plate.

Router has not see to many hours of use in my opinion. and no real hard use. As much as I hate to say it, it's like new..

Plates should save some time for a builder..

Send PM's or something..

The collets in the new spindle are ER25's and there are 9 sizes. I got the 1/2" collet with it and should have the others in the set today and will let everyone know.

RPM is 8K to 18k (or 133hz to 300hz on the VFD)

Spindle came from http://www.ekstromcarlson.com/

As I only just installed it this past weekend I have not had much chance to actually do any cutting with it so will have to report that in future posts.

Review of the spindle would be most welcome.

[wcarrothers1]

I will be posting about the spindle as soon as I run some stuff on it..

What size did you get? I am looking at the 6 hp model... I can say that they are "PROMPT" with emails....
Did you get thermal protector? Or the Thermistor relay?

Hello..

Well just got done using it for some runs of paths I used to do on the PC..

Dropped it from 4 passes to just 2.

Things to note...

you can tune out cutter freequencies (ie varry the speed of the spindle on the fly) till the cutter produces as little noise as possiable..
That is very cool so far..

Other things to note..

The darn tool does NOT get warm. By that I mean. The bearings in a router run HOT. Compaired to this after running some 30 min on a job. The bearing, housing, bit, shaft, collet are not hardly warm by the touch. I don't have my touchless temp gage but not hot or even hardly warm to the touch is very cool..

Sad thing was I increased elements of this tool path cutting passes from 4 to 2 and stepped up the speeds 70% from what I ran the PC and and it was NOT even thinking hard about it.. WAY WAY WAY cool..

Spindle model is the SM-C73
Uses ER25 collets

That is coupled with the following from automation direct
GS2-23P0 VFD drive (1 or 3 phase input to 3 phase output) (I'm running 1 phase in)
GS-23P0-LR-1PH AC LINE REACTOR, 230V, 3.0HP, 1PH, FOR GS2-23P0, INPUT ONLY
32DRT1W3C EMI INPUT FILTER 230V 32A USE W/ GSx-23P0
GS-23P0-LR-3PH AC LINE REACTOR, 230V, 3.0HP, 3PH, FOR GS2/GS3-23P0, INPUT/OUTPUT (sed for output
GS-CBL2-3L KEYPAD CABLE GS SERIES 3M

and pick out a latching 22mm button to use as a separate On/Off control button for the spindle on your machine. Also a contactor for you estop switch to might be nice.

Anyway very cool..

Also wired in a 30 amp twin pole switch for powering things on and off

I'll go into details of wiring later, and settings. But it's quite streight forward to wire in my opinion

I can measure resistance in the leads that are marked thermistor from the unit. How ever I don't have them tied into a thermo switch just yet. But would be easy to do I suppose..

Depending on the VFD you might be able to connect the two thermistor leads into the VFD for protection. Check out the VFD manual, you might be lucky.

I am sure it's much better than a router, for one basic reason. You could buy 6 or 8 routers for the price of that spindle...

I am sure that the wireing is really simple...
They offer a thermal switch for it...
As for an on/off switch, why not use a M03-M08 for on/off spindle control?
The E-Stop should be connected to the entire machine... If you stop the spindle, you are still moving? Not to good, when you have a $400 tool in it...
