You have not indicated the diameter of hole you are drilling. This is very important as the drill penetration rate may be limited by its strength. My experience in drilling 300 series ss is that the cutting edge needs to be be moving at a vigorous pace in order to avoid work-hardening. A chip...
Ian,
Perhaps if you telephoned Norton they might be able to suggest how you can acquire a copy.
Another thought: If you have a specific problem that you are trying to solve you could post it on the appropriate forum.
I am not familiar with the manual you are seeking but I am familiar with the Norton Company of Worcester Massachusetts which manufactures finishing materials. They may have authored the manual. If this is the correct company they can be located at: http://www.nortonabrasives.com/
or at 1 New...
You are in a lose/lose situation. The torque requirements for such an operation are way beyond manually operated air drills. You require a constant feed rate and rotational rpm. The drills are getting dull because when you drill manually you cannot maintain a constant feed rate, plus air is...
mrmrec,
Getting back to your original question. I have never worked in a shop with the atmosphere as relaxed you describe it, but I have worked for a company that ran a very tight ship and also one that had a somewhat relaxed atmosphere.
The highly organized and disciplined company was in a very...

Addressing your comment:
"I thank you all for your comments, my question originated from the fact that a common cnc machine is accurate to give a true position of 0.004 mm, if so, what are the main reasons that class f tolerance gives +\- 0.05, and what measures should be taken to...
The major POTENTIAL problem in that environment is the fact that the boss does not address the non-conforming behavior of the slobs is an INSULT to those people that do obey the rules. The boss can make any rules he wants to, or not. The atmosphere need not be tightened dramatically, the boss...
TREE342,
YOUR STANDARD SHOULD REFLECT THE MOST EFFECTIVE WAY OF PRODUCING THE PARTS. IT WOULD SEEM TO BE LESS COSTLY TO HAVE ONE OPERATOR SERVICING TWO MACHINES THAN TO HAVE AN OPERATOR AT EACH MACHINE, ASSUMING THAT THERE IS NOT ANY SUBSTANTIAL MACHINE IDLE TIME AS A RESULT. EVEN THOUGH I AGREE...
Hi,
I am a little late getting to this, but I will give you some input from my standpoint anyhow, and hope it may be useful to you. Effectiveness of a process is the product of efficiency and utilization. Determination of what is the optimum for each element varies from process to process and...
Tom, I agree with a lot of what has already been said. As already mentioned, 316 work hardens quite rapidly when a tool is creeping along, or allowed to dwell. For that reason, the most important thing is for you to keep that tool moving ahead as rapidly as possible within the constraints of the...
Someone has to make a decision regarding whether you want to achieve the 8 second cycle time or achieve the quality level stated. The two are incompatible on the machine and tooling you describe. You have already used up thousands of seconds experimenting, with little to show for it. Drills are...
In order to meet your requirements you need to contact some used machinery dealers in your part of the world. If that is not possible you can find many dealers in USA, Asia or Europe who collectively have many items to offer. Shipping costs may be prohibitive however.
The machines you are...
