Mag Chuck on a cylindrical grinder

[vbavaro]

Hello all, long time viewer first time poster here so please forgive me if I’m in the wrong thread.

In my 25 years of machining I’ve done a lot of things however cylindrical grinding I have only done a few times and it’s been a while. I have used a Kellenburger and a landis. When I did use these machines They already had a mag chuck mounted so I’ve never went from a chuck to centers or vise versa.

Currently I have purchased a Taiwan made Lian Feng LF800G with a swing down I.D head. I know it’s a cheap machine but it’s to do 1 quick simple Internal operation every once in a while without setting up a tool post grinder on the lathe so my budget was low.

My plan is to mount a 8” to 10” mag chuck on the workhead and touch up an angle on the Inside of a punch after sharpening on my Okamoto surface grinder.

All that to get to these actual questions . I don’t know much about the workhead on these or this brand of machine in general. Does this look like a standard spindle? Does anyone have any info or schematics on this machine? How do I adapt a mag chuck to this? I do know it’s an MT#4 for the center. I’m used to standard lathe spindles such as A2-5 and D1 cam lock so I need help on where to start to mount a mag chuck. Please help. Thanks. I’ve included some pictures of what I have. :

I've worked on a Kellenburger and the mag-chuck was bolted
To a faceplate with a ground tapered shaft that slid into the ground I.D of the workhead. A drawbar was then was slid thru the backof the workhead and screwed into the faceplate to pull it in tight .

Then the headstock is trammed square and often ground a ticket grind to be dead flat. it is a little tricky to tram the chuck, one might indicate over a jo block to get zero-zero at the same diameter on the chuck face. Feel /blue a flat parallel horizontal and vertical to know the mag chuck is flat bother ways. when ground, place a line-up mark someplace to be able to knock it out and back in near the same radial place. to be perfect you may need to grind it each time you take it out.
I had a friend who did between centers and all kinds of work/parts with a mag chuck.0
some times one is just mounted to a knock-in face arbor licked in the head stock taper.
One might get used to trying a two and three-finger push on a setup. Two fingers means you have a chancy set-up..three fingers is border line.

bvabaro,
I have an 80's Ribon Rur universal cylindrical grinder. It has a #4 morse taper in the headstock. Looks like yours may have the same. My magnetic chuck has a backplate with that same taper, also have a 3 jaw chuck that mounts the same way. A four jaw bolts right to the spindle face. They all work well. The morse tapers have a threaded hole for a draw bar.

Apologies for the hijack. I've got a Ribon Rur and can't get the chuck off could you PM me on how to remove it.

I have a mag Chuck off a Jones and shipman cyl grinder, we used them for flat washer tube things.
I use it on a lathe now , works with HSS, not carbide, work pulls off.
