Work is fairly slow in the shop, if I can save $400.00 (the cost here) with a few hours work, its worth it to me.

Looks like we could grind the carbide blades between centers and lower the bushing by however much we grid off the blades. Anyone done it? Any tricks I should know about? We have already reversed the...

No problem, just over 4" thick, 150 parts per stack, mixed stainless and aluminum. .005, .015 and .050 thick shims. Only broke the wire 1 time.

We did the entire building (shop and offices) a few years ago and haven't had any interference. Eliminated ballasts and did a 1 to 1 replacement of fixtures, so no re-wiring. So far 100% pleased and...

Is the shape / size / material of the electrodes on the other machines the same? Cables / grounding / maintenance any concern on this machine? Dielectric the same, and same condition / age? ...

Its not a matter of dull punches, new or freshly sharpened punches and die buttons still leave a burr. I'm going to decrease the clearance and see if that helps. Yes the slug is what I am interested...

Customer is punching .021" thick 316 stainless 2 layer mesh (sintered wire screen filter). Its made of stainless wire that has been fused together to form a very fine filter. Starting with a .569...

We have done plenty of stacks screwed together, so I think we will be fine with keeping things secured, l know the potential problems well. My concern was only with the different material in the same...

I have an order to make several hundred shims, 3 different styles. I will be stacking 50 each .001" stainless, .005 aluminium and .010 aluminium sheets, screwed together with a top and bottom 3/8...

Being asked to quote some parts that have a .0001 - .0002" thick TiN plating. Four surfaces have to be surface ground after plating (no plating allowed on those surfaces). How much of a headache is...

Peter,
Learned something today, never heard of quad rings or X rings. I've worked with O rings for my whole career. Googled them and and understand the advantage. Wonder why they aren't more popular?

Point taken, never scrutinized to that level.

Marcus,
Do the Makino precision EDM drills orbit to maintain size? Or change electrodes? Hard to imagine how they could do it with conventional hole popping technique.

Mike,
Drilling hardened...

Just a note.
Measuring the working end of a new carbide end mill with a manual micrometer is a great way to ruin it.

Bob,
Ruin the end mill or micrometer? Curios why you would say this, I've...

My experience, you won't hold .002 tolerance consistently. The electrode will be tapered as it is being used, and the guide and electrode needs clearance which will cause some run out. I think you...

I meant thread milling in a VMC. I guess arbor or shank and insert would have been a better discretion.

I've never tried it, can't find an answer on line and have a job coming up the requires a 1/2 -20 left hand thread. I have the correct inserts and bar for 20TPI, but have never tried left hand (multi...

We built several coalasers several years ago and have been pleased with the results. Not portable, but one for each machine. There was a thread that I put pictures in, but I don't remember what...

Looks like a great deal. I have one I bought new about the same vintage. I have all manuals and schematics if you need something. I have a newer DRO also, the original crapped out after about 20...

I have never used them, but they have quoted a few things to me. Never got the jobs so, didn't need their services, but seemed knowledgeable and competent. Don't know where you are in Georgia.

A couple of thoughts. If you really like your present position and feel well compensated and enjoy the challenge of something different all the time, stay where you are. My only question about...

What diameters for saw and arbors (to calculate depth of cut)? Looks like a really handy tool to get close to vise jaws or fixtures.

You will be sacrificing time by interpolating in rapid. May be safer, but it is also slightly slower. Shortest difference, but on long moves it will take longer.

Find a shop with a EDM drill, easy everyday work.
