Thread: Ozito Router For CNC

Mine has not stopped yet it is sitting on the floor collecting dust, anyone want to buy it

I got a Milwaulkee die grinder, it is much better in the bearing department. I think the Ozito is a good starting point though, $45 is not a lot of money either.

I was just wondering if it'd be worth buying ozito and putting high quality bearings in it before using it.

I think I would just use it until it needed them, then replace them

Hi Bob,
The bearings are fine. They just burn out as they are not made to run for long periods. The heat just keeps building up and they let out the magic smoke.
I had three burn out (no I didn't claim warranty) before I got a die grinder.
They were good for about 100 to 150 hrs though which I thought was failrly reasonable so I am not knocking them.
A die grinder is good for about 500 hrs and then it is a $30 brush replacement. None of us have totally killed a die grinder yet.

My experience with ozito was a little different. I've had two, still got one of those.

Only when brand new could i run them at full speed.

Soon after you would not be game to be in the room with it at more than half speed. Swear it was about to disintegrate.

But more important was the runout. Just not satisfactory for CNC work.

I would not waste another $50 on one. As I say that has been my experience.

Others have faired better.

My unfinished machine is setup to take 4 routers so I can have 4 different profiles to use without changing tools. As well as an angle grinder so I can machine into edges with the same timber setup. I'll fit a collet chuck to the grinder so itll take a router bit.

I actually have 4 gmc routers of similar style as the ozito., But I expect to use up routers and as they're no longer available, I'll replace them with ozitos as they packup.

Might be worth thinking about a separate fan forced air supply into the routers to keep them as cool as possible.

Haven't been near the machine for a few years but I expect to have more time in a few months so I will get back to the beast then.

That explains my industrial deafness - SMBO says it is selective hearing and sometimes she might be right.

Bob,
Greg makes a good point about runout. There is quite an expense to get a machine going so the trend is to go for a cheap router to finish the machine off.

Once up and running things change because woodworking hacks can now do high precision and detail that very few trained woodworkers can do by hand.

So the goal posts shift after a while and down the track we upgrade our machines trying to get even greater accuracy and faster production.

I like your thinking - don't worry about an automatic tool changer just have four quick change routers on hand. Thanks to Greg we have a $15 electronic zeroing plate so you can dial those routers in to your job.

A cheap computer fan would be worth trying.

Can you point me to that thread please Rod

Greg has also done a laser crosshair zero device for X ans Y axis. I used a cheap $20 web cam to do the same thing.
I have attached photos of the webcam and the result. It has about three times magnification so real easy to find where to start the job.
With all three axis able to be positioned setting up jobs is a breaze now.

thanks rod, I have a good look.

Im actually a fan of the little ozito router, I had clocked up over 200 hours when I decided to change it, I only changed it becuase I wanted to get a setup with a 1/2 router, I was still very happy with how it cut and the mirros I engraved with it. When I pulled the ozito off the cnc, it had massive slop in the bearings but it still cut nice. For 50 bucks I highly recommend them, most people without a cnc, you would be lucky to have used the router for 50 hours, so I do believe they are value for money.

If your willing to spend the big bucks then yes go bigger and better, buy a makita for 360 dollars etc, but when your starting out its a lot of money on top of what you have already spent

Personal choices, Im very happy to recommend them.

There have been so many good comments on the little ozito on many threads I don't see any major issues with them. Eccentricity is usually the collet & swapping collets is an easy fix. If the shaft bore is off centre then fitting a cutter with a dial indicator will usually get both blades in the same cutting arc.

You blokes who are using ozitos on cnc machines are working them much harder than any bench router would be used (apart from abuse). So by treating them as a consumable in the same way as cutters are consumables, then they should be quite worthwhile. If I got into the production that my machine was designed for then 4 new routers a month is a very minor maintainence cost.

As I said previously I setup Gmc's not realising they'd be discontinued, so as I swing over to Ozitos I may hafta refit the routers but with a bit of luck the spigot bosses might be a suitable diameter anyway. My little routers probably won't get get overworked a lot as they will be for vee, cove & small straight cutters. My primary router is a Hitachi TR12 with 90mm long straight cutter. There will also be a right angle router (angle grinder with collet chuck on a 4th axis) so I can cut mortises into the sides of the part being made.

I probably won't get back to the machine for a few months yet, but I keep my eye on whats happening in the cnc world.

Rant over

Interesting camera, can you tell me where you got it from?

Cheers.

Got them on ebay. I wouldn't have thought they were still around with rapid changes in that technology but found one here
Not recommending that seller just pointing you to the product.
