Thread: Need air clamping schematic for Brown & Sharpe Microval

The plastic/rubber tubing that routes the air for axis clamping on my Microval has deteriorated, and I need to replace it. Does any body have a schematic of the air clamping system for the Microval?

I have a manual for a Micro Validator CMM (MicroVal A, ca 1989) that includes a block flow diagram for the air system. Would that be of interest?

That would help. How can I obtain a copy of that diagram? I will leave a personal message for you with my e-mail address.

Sorry - my inbox was full but space should be available now. PM me with your email address and I'll email off the 3 pages on the air system, which I've just scanned.

Bruce,
I am going to tackle the tubing replacement on my Microval starting tonight. I have the schematic and a parts machine for reference. Literally every line is broken. I will start a new thread and will report the interesting bits.

I have thrown in to towel on trying to re-tube this machine by myself. The tubing problem came up all of a sudden, after I successfully completed a reverse engineering project. So the electronics on the machine are OK. I have contacted a calibration and repair service out of Blaine, Minnesota, and they have assured me that they can re-hose and re-calibrate this Microval for $2,473. Upon looking what it would cost to replace this machine, I feel that this is reasonable.

As of last night I have 5 hours in it. I expect to have 8 hours in it total. It takes an extreme amount of patience. I had to make a special tool to hold and attach the hoses in some spots. This is my personal machine, so I can afford the time and frustration. I can see why you would choose to have it done by somebody else. I think these are great old machines.
