I just grind right on center but my fixture is always set square. Ground some D2 punches recently on a harig head and no problem with taper. Stamping mylar so shot for 0.0001 a side clearance on punch guide and 0.0002 on die. Next time i find a little taper i will try going off center but don't think it matters much if care is taken to get fixture square. I was grinding a form with 2 different size radiuses and 2 flats. If I'm off center tangent points will be off so going off center in that situation would be bad. Nice video and ty.

I noticed a repetitive stutter in your grinding even after multiple passes. What is causing that? wheel balance? Something in the spindle on the spin fixture? When grinding off center does it try to lift the part any from the cutting forces? I could see that becoming an issue next especially when grinding cantilevered.

Hi Brian, It is in the drive belt where the 2 ends are fused together. You can see it under an indicator. It is about .0001 TIR. Steve
@SolidRockMachineShopInc

Hi again Brian, I have a few ideas on how to fix that issue. I have seen this issue on other Harig fixtures of this same model. When you spark out as I have it is less than .00005 indicator bounce. The bearings in this unit are not as good as in some of the other Harig spin fixtures but it is a cheaper unit. For a lot of the things we do it is accurate enough. One of my new project well be a fixture to grind between centers and that will be more accurate than this unit. I see in your last video that you have a lot of insulation hung in your shop. I am guessing you have much more now, can you tell a big difference in heat yet? Steve

It has made some difference but not alot. Until I can get a ceiling in or do something about the roof vents all tyhe heat will just continue to go up and out. Maybe you could take some sandpaper to that spot in the belt and smooth it out?

Hi Brian, There is a very slight miss match where the 2 ends connect but I think the problem is that it does not flex as good at that point and I think that is the problem. I am going to try to find some seamless o rings and see if that will make a difference. I may have to add a idler wheel to compensate for stretch as it gets used. Steve

Great video! Thanks for sharing your knowledge. One question: when you set up the spin fixture and end up with a taper, how do know which way (plane) to correct? Left/right or up/down?
@SolidRockMachineShopInc
6 жыл бұрын
Hi Juerg, By going .01" to .02" to the left of the center line of the grinding wheel in relation to the center line of the spin fixture I only have to adjust the up/down. That is assuming you have the center line of the spin fixture running parallel to the Y axis. If the diameter is big at the farthest of the stick out then you need to adjust up. If it is small then you have to adjust down. Steve
@yogisworkshop
6 жыл бұрын
Thanks Steve. What if it error comes form a spin fixture axis that is not parallel with the Y axis (lets say from a mistake setting up). Would you still go to the up/correction to compensate, since the wheel is offset and is making a taper?
@SolidRockMachineShopInc
6 жыл бұрын
Hi Juerg, That would be much harder to work out the taper because if you adjust the up and down when it really needs a Y axis alignment you will never get it just right. One way to line up the Y axis real close is to put a part with a shoulder in your spin fixture and take a clean up cut on the shoulder with the side of the grinding wheel and set your dial or readout to zero. Make sure the side of the wheel is relieved so that you have a very thin section of the side of the wheel that cuts.Then pull the wheel back off the shoulder of your part and ink the shoulder with a Sharpe marker. Then slowly wind the wheel up to the shoulder of the part with the spin fixture off so the part is not rotating. Just barely touch the shoulder with the wheel and back off the part so you can see the shoulder. If you have a nice even line on both sides of the shoulder then the Y axis is lined up good. If you have a line on one side but not the other then you have to adjust the spindle fixture side to side until you have an even thickness line on both sides of the shoulder. Maybe we will do a video showing this technique in the near future. Steve

Solid Rock Machine Shop Inc. Certainly not a waste if you learned something, and taught many things in the process. As I tried to think through it the only way I could think of to do it was a CNC lathe. Surely it's the easiest if you have access to one, even if there are other ways.

Hi steve, could you please advise how to grind aluminium plates for best results?
@SolidRockMachineShopInc
6 жыл бұрын
Hi Fischer, Aluminum is hard to grind. I think that would make a good video. Aluminum likes to load the grinding wheel because it is very soft and it wraps around the individual grit. Wheel selection is important and the best results I have so far is to use undiluted coolant in a cup and use a brush to apply it to the work piece. I just talked to Adam and we will start working on a video right now and hopefully have it posted by tomorrow. I have never used some of the newer wheels on aluminum so it will be a learning curve for me as well. Steve

Solid Rock Machine Shop Inc. Thanks steve! Can hardly wait. Also ...i need to grind a plate which is larger than my x movement. Is it possible to move the part and grind it in two operations or i would lose precision? Movement is 280 mm, part is 550, aluminium, blow mold plates.
@SolidRockMachineShopInc
6 жыл бұрын
Hi Fischer, We just finished your video. I think you will be surprised at our conclusions. To give a tease, I only had small pieces of aluminum but the first wheel I selected worked so well I had to throw in the towel. The part was only about 2.625" * 2.75" but I took .031 off at .001 at a time trying to load the wheel. I gave up after .031without redressing and the finish was great and less than .0001 flatness. The video was going so long we only tested 2 wheels. You will lose precision by moving the plate but you can minimize it with a good game plan. If you can bolt some very flat precision blocks to the bottom of the mold and space them just right you can get good result. Your magnet will have to be in good shape as well. Steve

Pro Tip: While you're doing all this messing around, trying to make a surface grinder do something it wasn't designed for, or intended to do, keep you eyes open for a dedicated cylindrical grinder.... I know... I know... They're expensive... But, you have no idea how much fun it is to run a precision grinder without having all these hassles.
