If the Bijur lube pump has been set to put out the correct amount of oil, I don't think you want to change it. Does there happen to be a controller output you can use to turn it on and off so it...

I thought you said "complete." Try http://www.ajaxcnc.com/
Which I'm told is Centroid equipment in DIY form.

For everything in one package, Centroid:

I've had two over the last fifteen years, and am happy.

Given that the motor appears to work, just somewhat lacking in power, how about physically swapping the X and Z axis motors, which I believe are the same? I don't think the Z sees as severe service...

I would suspect so. As I recall, the stuff is actually all in the programming; you pay your money and they send you a key code to enable it. Mind you, I was dealing with Centroid, not Ajax. When we...

I've been running an old BOSS Series I that was upgraded with servos and Centroid M-15 control about ten years ago, and like it. Never had any major problems other than disk drive failures, which we...

Well, that's odd. I thought that was the procedure for adjustment, since the nut runs on continuous threads, and moving the stop screw should allow it to pull up further. I'll admit, I've never had...

Ditto on the admonition to use only Erickson brand tool holders. I run the spindle on my BOSS 6 up to 5k, only hand tighten with the short spanner provided, and have never dropped a tool.

Here's...

Any of the 30 series taper tool holders will fit your spindle IF you have a machine with a drawbar through the spindle. The worst that can happen is you'll need different drawbars to match the...

I just did likewise on an old BOSS 6 that had a clapped out Vari-drive that had eaten the motor shaft. The BOSS machines have a very squat motor with an eight inch long shaft, not one that was going...

I have a couple manual Bijur lube pumps on manual machines, and the electric timed pump on a BOSS mill, and all have been trouble free. However, I’m also responsible for an injection molding press...

I've always heard "tilt" refer to rotating the head in the ZX plane. The term I've heard for rotating it in the YZ is "nod", the same as nodding your head. Not that it matters; the rigid ram does...

DON'T do it! VFD's do not like being disconnected under load, and operating the reversing contactor will likely blow the VFD.

I've just gone through this, putting an AC Tech VFD on the spindle of...

I’ve been running a B’port BOSS 6 on two different Centroid controls for the past ten or twelve years. The machine originally came to us already converted with a Centroid control (I forget the model...

You think you're confused… This stuff is made by Kennametal now, who is owned by (or owns) J&L Supply. If you go to the J&L web page at:

It's Erickson QC 30 Quick Change. It has the same taper as NMTB 30, but the locking collar is...

Doesn't sound like such a good idea to me. I actually owned a factory single phase M head machine once years ago. The biggest problem with a single phase B'port is no reverse. Yes, I know they make...

I think most servo conversions make use of the existing drive pulleys, I know mine did. Therefore no one has a spare set.

Dennis

All that effiort, and they missed the Ericson Quck Change QC30, which is now made by Kennametal. MSC Supply also carries most the line. This is NOT interchangeable with NMTB 30; the taper is the...

That sounds like the standard North American "high leg" three phase service. All the "legs" are in balance, 240V between conductors, but one phase to ground will be a high voltage, around 208V. This...

I concur. My Series I BOSS measures 46.5" (1181mm) from the left edge of the table over the X axis ball screw nut on the right side, and I'd rather not be banging that nut against anything, so 48"...

Where are you measuring the runout; inside the tool holder collet chuck, or on a dowel pin chucked in the collet? If the later, it might just be the DA collets are beat. Try buying a new one (they're...

The problem with backlash comp is that it doesn't solve the main problem caused by backlash. All backlash comp really does is tell the stepper (or servo) to add some extra steps when it reverses...

These things show up on the E-bay auction site from time to time; that's where the motors from my machine went when I converted to servos. I don't see any on auction at the moment, but this guy lists...

Thanx. Wonder how well they work when the Bijur oil creeps over them? Worth a try if the mechanical switches continue to give problems.

Dennis

Looks like no one has had this problem, so no one has an answer at their finger tips.

I had some time to pull the switches out this afternoon, and they do have a part number on the back (hidden)...

Here's a simple replacement part question. Does anyone have a suggestion for a replacement for the Z limit switches, the ones on the quill drive behind the motor switch panel?

I'm running a BOSS 6...

Erikson was bought out by Kennametal, which is owned by J&L Supply (or maybe it's the other way around) Go to:

I just had to pull a Series I Boss vari-speed apart, and I noted with interest that there is a whole section in the manual on converting the machine to air driven brake and speed control. It looks...

Are you sure the new cylinder has exactly the same stroke as the old one? Is the rod extension the same length? My Series I Boss stops so fast we were originally concerned it would unlock the...
