Well we have been using the wiggle type for years, I've tried an electronic one but wasn't happy of the accuracy. We work to .0002" / 5 microns.

I'm looking at the following:

Enco - Guaranteed...

Thanks for the reply.

No there is no C plugged in.

From what I gathered its my back up settings that have not been installed.

Any ideas?

Hi,

We currently ran into hard drive issues with our Torq Cut 22, DX-32 controller.

I changed the hard drive, reinstalled DOS 6.22 and the operating software to version: 4.30/6.81.

Hi,

Our company is looking into purchasing a new high precision CNC lathe with live tooling and Y-axis. We manufacture parts with 5 micron tolerances so I am looking at the following brands with...

ok just to answer my own question and lend a hand to others that have the same, i found some trial software on the web: http://www.connectcnc-dnc.com/index.html

yeah finally!! have to say hardinge is one of top lathes, we have a t42sp about 7 to 8 years old, had some very bad crashes and she still holds to 5 microns!!! trying to purchase another with live...

Hi,

I'm looking into updating the way we transfer our programs to our Hardinge Conquest T42SP CNC lathe with a GE Fanuc 18-T controller.

Currently we are using Procomm in DOS mode with a very...

Thanks I will look into it. Need to update me library

where can I get these? I have some old books im going by but they are out dated!! our machinery handbook is form 1964!!!

ouch!!! i wont be able to use this as an opinion now! LOL

yeah i have worked with both inch and metric for years, it drives me crazy when things are overtoleranced cuz then I gotta prove I made...

LOL!!! guys thanks for your respones!!!





These are the problems I deal with everyday with our engineering department. Most of the questions I ask in this forum I have a good idea on the...

I have a position tolerance on a 8-36 UNF-2B thread of 0.015mm to two datums. The only way I can measure this on a CMM is to install a thread gauge pin.

But isn't the tolerance of a 2B grade...

Yes that's how I figured it, thanks for your input.

Thanks cncprofessor, I cannot send the drawing at the moment but you have answered my question.

Just to be more specific:

Picture a cylinder (2" dia X 3" long), on the actual OD (1" from...

Hi,

Was wondering if anyone can help me on a question I have about GD&T tolerancing.

What is the proper defininition of feature of size? (FOS) Can a surface itself be a FOS? Is it possible...

Just wondering if any follow the saftey guard guidelines for a bench grinder?? I find it very hard to grind tools with the guard 1/8" away from the grinding wheel and also using goggles with the eye...

I wish we can loosen the tolerances but we can't, and we need the anodizing for ware purposes. I'm thinking we are going to have to "rub" any parts that don't fit.

yeah we have a diamond turning department at our facilites which cut mirrors. I make lens cells and camera mechanical components and we work to .005mm tolerances with not too many problems unless we...

guys thanks 4 all of your input i will b having a meeting this week to address this issue.

I'm looking at getting holtests for holes of .240" up to 1" ID, measure to +/- 0.0002". Was wondering if Brown and Sharpe are a good brand, I usually buy Mitutoyo. Also are the small hole guages...

we are working with 5 micron tolerances and usually we have to rub a bit of the anodizing to get parts to fit. My problem is how the drawing should be presented to the shop floor. The CNC operator...

The only problem with that is the coating will not hold a 5 micron tolerance.

At first we had a note on the drawings of zero build up, (we are requiring black anodizing as per MIL-A8625, type 2, class 2 on 6061-t6 aluminum) I don't believe there is such a thing as "zero" build...

Hi,

We are in a bit of a debate on how to tolerance a drawing with black anodizing coating. I would like the drawing to have the specifed finished machined tolerances before coating and then...
