Small Footprint MechMate Mounting Spindle and Support Board! - Geelong Australia

[gmcclure]

A couple of photos of the laser cut machine in Oswalds Factory. (files to large)

Not sure when the offical start date is however most of the machined parts are finished, bending and welding tomorrow.

Oswald and I are making 2 machines both 900 x 12500 wroking area.

Hoping to be finished by Easter.

Good luck with your build. That is some impressive size.:)

[Gerald D]

I think the 12500 is supposed to be 1250 [40ft vs 4ft]

[gmcclure]

Stepper motors arrived on Friday, time to make bench test.

Build going a little slowly, real work has been busy

[gmcclure]

Well its been a while (sick during the year), nowever here is the mechanicals for my small table mechmate (950 x 1250 work area)

Like a toy.....that will work hard
Congrats ;)

[domino11]

Now time to get some labels on her and show us some dust. :)

[MetalHead]

I'd like some detail shots of those belt drives !!!

[gmcclure]

Mike close in from the original photo. Will have to go ansd shoot some more detail and angles. Trust this us good for now

[domino11]

Are those from Mikes plates?

[MetalHead]

Nice job.

[Alan_c]

Graeme, nice job. Dont mean to nitpick but it looks like your Z axis is back to front, The plate that the router / spindle attaches to should face the front (where the Y motor is).

[gmcclure]

Allan,

You are correct and they are turned around now.

[gmcclure]

Heath,

No they are a modification of a design by MattyZee.

Ratio is 4:1.

Graeme

[MetalHead]

Make sure you tape over those holes on the back of your motors.

[gmcclure]

Long day today. Getting sick of drilling holes in 32mm MDF. Base Board all bolted down though, now to undo bolts, prime and paint.

Touch screen for MACH3 arrived the other day, works great 19 inch LCD. Loaded 2010 Screen and plugins for wbox control and smooth stepper.

[gmcclure]

3kW air cooled spindle arrived. Nice 6 hole pattern on the back.

[MetalHead]

Cool - can we see some pictures?

[Surfcnc]

Graeme - You walked right into that one :)
What no photo !!

Photos of Spindle and Mounting plate. Will establish another registration hole and mounting bolt hole 2.25 inches further up the Z plate.

[HomeMadeCnc]

Thanks for the post, I was wondering how I was going to do that. If you don't mind I'll be borrowing your idea

[timberlinemd]

Care to share the mfg/vendor of the spindel?

[gmcclure]

Steve,

I purchased the spindle on ebay form love-happyshopping in Hong Kong

[Gerald D]

From the pics, it is identical to the Italian-built generic family of spindles under labels like HSD and Fimec.

[KenC]

18,000rpm?

[gmcclure]

Spec states 24,000 rpm. I will see when I power it up. Made in China, don't have to high a hope but won't be holding back on it either. Dought if I will be stressing the unit to 3kW at 24,000 rpm so believe it will work at the higher rpm with the likely loading the unit will receive.

[gmcclure]

Support Board all painted and bolted in. Just poured the casting resin on top of the bolt heads, time to wait for it to set.

Found out yesterday one of the cables is on back order until mid May :(

[Surfcnc]

Hi Graeme

That will give you some time to slip down to Bells for the Ripcurl Pro !!

I have checked the no load speed of the Chinese spindle with a digital tacho and they do spin at the rated RPM. My research however indicates that at 24K the bearing life would be significantly reduced from 14K usage pattern regardless of any side load being factored in.

I have the same spindle, had it for about 6 mo. same supplier, its a work horse.. when I first hooked it up it started in reverse and jacked the fan thats bolted to the shaft up into the housing so had to do some fixing, got a look at the bearings at that time, its as Gerald said, a copy of the HSD..

[Kobus_Joubert]

Hi Dan and Graeme, I just ordered my 3kW air cooled spindle and a set of collets this week.
How did you fix that plate on the spindle ? Does it have pre drilled and tapped holes ?
Mind sharing the DXF for that QUICK RELEASE plate as I plan to attatch it to my Z-plate in the same manner. I had my routers fixed onto this quick release plate from the beginning.

[danhamm]

Yes there 6 I think 5mm tapped holes...but its into aluminum, seems ok though..I am remodeling my bot I picked up last winter..

Sorry for the quality...Iphone..pics

[gmcclure]

Sorry Kobus,

I made the quick connection plate manually on a mill using DRO setpoints. The spindle does have 6 pre tapped hole in its body

regards

Graeme

[Kobus_Joubert]

Thanks. Can you give me the centre to centre dimentions so long. Then I can start with my plate.

[Gerald D]

Kobus, 11650 is the file supplied by HSD, but the 36 mm between centers has been 30mm on one of our spindles.

[Kobus_Joubert]

Thank's Gerald.


Graeme and Dan, did you also pick up this problem ?

Maybe it will be safe to wait and measure it ON the actual spindle.

[danhamm]

As I recall it was 30mm horizontal and 45 mm vertical total 90mm vertical.

I am talking about the air cooled 3kw huanyang spindle pretapped mounting holes on the back of body..

[Gerald D]

Here is our spindle with the 30mm spacing:

[Gerald D]

Kobus, sorry to confuse you, that first drawing with 36mm was a 4.5kW big one. Safest is to wait.

Also watch that the screws don't bottom in the tapped holes - they are very close to the coils inside. Don't make them too short either, otherwise you will strip the alu.

[revved_up]

I have found that the ebay seller list the same spindle multiple times with different pricing so best to scroll thru all his listings

[Kobus_Joubert]

Different price, but then also different shipping cost...in the end the same price...:cool:

[KenC]

I run my present 2.2kW spindle in the region of 8~10A most of the time @16000~20000rpm depending on the cutter sharpness...
Been dreaming about uprating the spindle when money is available...
BUT 3kW or 4kW spindle... Just can not make up my mind...
