Sharp Milling Machine Help

[bobby light]

Have been trying to find a decent Bridgeport J model for quite some time now. Today I ended up with a Sharp-LC HMV Milling Machine. So far it appears to be a clone of the Variable Speed Bridgeport. Machine has minimal backlash, and came with X axis Servo 150 power feed. Also came with an acuright III DRO

I believe it has an R8 spindle taper, but when I looked inside the spindle taper I don't see the little key way for the the collets to slide into. Is that correct? From all my research I don't believe Sharp HMV mills were made with a different spindle.

Last I was missing the draw bar, but other then that the machine is complete. Can I purchase a draw bar from enco and if so what's the best way to determine size?

Give me a few and I will get some pics of the machine. It's still loaded on the trailer. Not looking forward to moving it.

The head was swiveled upside down for transport.

Yes, the Sharp mills (and nearly all knee-mills now) take R8 shank tooling and collets. A drawbar would be a good project if you have a lathe. I believe the R8 shank collets and tooling is 7/16"-20.

Yes I have a few lathes

SB 13, SB 9 and a SB Heavy 10

So why is there no key way inside the spindle taper for the collet to align with and slide in?

Id like to get the machine running asap

Figure this is what I need?

They key's break off. Not really a problem. Our sharps at school are more or less identical to the bridgeports we have. They have r8

I prefer it without the key way in there actually.lol I wouldn't worry about it. Run it....

Thanks for quick replies. It was more of an impulse buy, which I don't like to do when it comes to machinery. For the price it was worth getting this nice machine that will need a little elbow grease to become operational, vs a worn out J head Bridgeport which people want an arm and leg for.

Already have a rotary phase convertor for it, just need to her her moved into the garage. Now I can sell my clausing 8520.

That table is covered in grease, but doesn't have a single drill or nick in it! Really happy with this machine, even though its an import which goes against all my other US made machinery, but I think this was a better buy vs a J head Bridgeport which would also have cost more money.

I love our sharps. Very nice machines. They are new but you can tell right off they are well built

Hey, seems like I read that when u invert the head like that u need to make sure you re oil the cups good and let the oil get back where it needs to be....

Seems logical to me. I need to add a good amount to all the cups. Any recommendation on oils to be used for this machine?
