Tsugami T-CDG150

[chrisemParticipant @chrisem]

I couldn’t resist this tiny grinder.
If anyone has one, or any information, please let me know. The centres in the head & tailstock are 0.240” at the large end. A good clean and oil / electrical check, & I will try and get some power on it.

Is it single phase ? Or do you have 3 phase ? Noel.

[chrisemParticipant @chrisem]

It is 3 phase Noel, & yes i do.

There is a transformer inside, so I suspect some of the motors could be lower voltage than 415.

[noel shelleyParticipant @noelshelley55608]

The transformers may be for control circuits and lighting ? Noel.

It looks a lot like the one pictured on the front cover of a Levin/Tsugami catalogue listed on Vintagemachinery.org’s site

I don’t know whether that will help in any way, but it’s a start.  I could find no reference to Levin (other than lathes) nor Tsugami on lathes.co.uk.  I didn’t search further, I’m afraid.

Extensive  write  up on this machine in Lathes.uk  look in Grinders, Polishers, Lappers, Sharpeners, etc.

Big heavy  machine   which has a limited work envelope   for model enginnering   use.

Looks like a useful little machine.

There are some photo’s of one for sale in Japan.

TSUGAMI CYLINDRICAL GRINDER

[John HinkleyParticipant @johnhinkley26699]

Well found JohnP.  Didn’t turn up in my use of the search facility and I was too lazy to scroll through the list of grinders. Useful extra data over what’s in the brochure maybe.

Thanks all.
Very useful. I will have to tap up some contacts in Japan & see if I can track down a few accessories.
Sadly it looks like the wheel dresser has taken a walk. Very small 4” wheel & tiny little centres.
I really need a proper lubrication data sheet. The stuff I use in the jones & shipman should be fine to loosen things up. It all moves, but feels greased. 20-30 year old sticky oil.

A great asset for a home workshop,  I wish I had the room for such a machine.

I have not had any luck with a manual or lubricant chart as yet. So I took a guess at a light Tellus slideway oil and Nuto 32 for the wheel head spindle. Carried out an insulation test, wired the machine into an isolator & fired it up for what must be the first time in decades. Many belts are perished or stretched, but it all works to a fashion. Table feed only functioned in one direction, and a long spring inside the base with a short length of snapped rope was identified as the cause.
I wanted to remove the table anyway, so removed the table travel stop screw from the right hand end, and slid the whole thing off to the left.

This is what lies under the table. The T slotted carrier with the screws traverses to the right under pressure, then is drawn back to the left by a vertical coil spring in the machine base. This spring is hooked to a braided rope that runs over a pulley and onto a hook under the carrier. The broken end of the rope can be seen in the photo. Sitting in the T slot is a long nut. This can slide freely in the slot until feed is engaged. A pin moves up into a hole in the base of the nut, and the two parts move as one. There are a series of oil feed holes and grooves to lubricate the mechanism. Everything is ground, many parts scraped.

The 58 year old broken rope.
I lashed together a temporary zip tie fix to test, & the table will now traverse both directions and automatic infeed operates.
Slideway scrape marks have all gone bar a tiny witness on the edge,  but there are no uneven patches or steps. Wheel head runs silently. Some work on the belts, the broken rope replacing, and it should be capable of a test grind. The whole thing needs a deep clean. One broken handle replacing, and poly belt sourcing for the work head and coolant pump.
