We are quoting on some making several different large 1 of a kind parts out of Delrin (5 by 10 by 40" $$$). They have a lot of detail and I would like to machine a tryout piece before we start...

It looks like Marty McFly's flux capacitor, but I may be mistaken.

I believe you mean the feedback comes from the encoder on the ballscrew, not the motor.

I believe creep feed grinders always climb cut, so that would be my guess. Coolant has better egress that way.

Yes, I think GD is correct. We have had a G18 for 20 years. We also have wire EDMs and if the hole goes through, we will wire it. If not, we will hard mill in in VMC. If that doesn't work, we will...

We have used the standard RS232 interface for 15 years and never dropped a single character. Serial port on your PC, snyc it up, make a cable, transmit data.

A good sulfur based cutting oil brushed on during the cut will help. Probably going to create some smoke and can get messy, but well worth the inconvenience.

Did they replace the seals? Or are seals external to the bearing assembly and part of the responsibility of whoever installs the spindle? Hard to judge without knowing the details of how everything...

If you are expecting shiney , not so much. But check with a profilometer a 6-8 micro inch Is possible with the right condtions and skims or orbit and electrode prep. Are you asking about wire or...

Much less frequently now that we have colasers (works better than skimmers) . 18 -24 months average, smell is one factor, contamination from plastic is a big factor for us. Keep tanks full and keep...

Just don't do this:

Cheap compared to what?

I've been very happy with Doosan, both lathe , mill, and mill turn. All Fanuc control.

Sounds like the upper contact is not secure. What holds it in place? I would triple check it. We have had similar issues and the contact starts eroding its holder which gets ugly fast.

Does the wire lay flat and coil, or just end up in a huge birds nest and short out? When chopper fails on our machine its the latter. Maybe without the unit on it would act differently.

25 years ago we used iron pipe, its still up in the joists working just fine. A few years ago we added an air turbine and started getting starved for air, so upgraded compressor and dryer, finished a...

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...
