Thread: Okamoto Hydraulic Grinder information

I work for a company that just bought a 124N. Everything works but the automatic down feed only feeds .001 each time it hits the crossfeed limit. Is there a way to increase the down feed amount? I have turned the screw on the side of the x axis wheel.

Hello Tod,
I first need to inform you that I will no longer post on this site, so if you need any further info contact me directly.

Increasing down feed beyond .001" maybe possible, but that is a super heavy cut. I have mine set to .0003-.0005.

First off, the "action" of the pawl grab should not be aggressively quick, their is a valve that controls the force of the push, it's a knob just left of the hand wheel.

You are trying to go much deeper per pass than what is normal, adjusting this valve may get you to a deeper cut, but not much more than .002.

Read my previous post, I did have to repair the valve on my grinder.

I hope this helps, but you need to contact me directly if you have any other questions.

That is sad to hear.
For sure many have been not nice but your input is valuable and cared for.
You should not quit. Raise your flag tall.

Thanks Bob.

But if I don't get my "toolmaking forum" I'm out.

Just thought I'd say thank you for this thread. We have an Okamoto 1224 grinder here, bought at auction. It's the first grinder I've ever setup, and the first grinder I've ever used. Took a little bit of troubleshooting, and a little bit of testing, but ever since it's been reliable with good results. The one issue we had was that the swarf (is that proper grinder terminology?) would build up clumps, and then clog the drain that goes out from the table area. I simply used a few 1/4" magnets in front of the drain, no more issue. I just need to clear off the metal debris from the magnets occasionally.

You could always use a stand alone bypass filter similar to the Sunnen units that just have a hyd pump and a large micron filter. It picks up returns the filtered oil to the res.

It's beginning to look like I'm going to have to replace the spindle bearings in my Okamoto 1224. Looks like there are 4 of them, 7210 size. I presume ABEC 7. I've done spindle bearings on a small lathe, and in a Bridgeport. Is anyone aware of anything that makes these particular bearings a pain, or any tips specific to this machine?
