Thanks again everybody for your input regarding this issue.
At this point we have implemented the use of Saf-T-Eze Ni Anti-Seize. A small amount is applied to the first three threads, and threaded into the hole. We tested three different lubricant types; WD40, Multi-purpose Grease, and Anti...
We currently use helicoils for thread repair/replacement. The saws we use cut silicon ingot.
The set screws are m10x1, not the standard 1.5. The set screws we use have a non tapered flat tip, so the diameter is the same as the minor diameter I believe...Nickel Plated, I inspected several of...
diamondjim,
These are set screws for tensioning an ID saw blade. I was being cautious, because I am not sure what the company rules are as far as talking about specific processes. But, at the same time we need to try and solve this problem.
The blades are tensioned by turning the set screws...
These are torqued in series. Each revolution of the ring we stretch the sheet metal about 100µm. So we are going around about 12-13 times. The starting screw has the highest torque value during the tensioning process.
I will contact Loctite on Monday. Thanks for the help again.
Do you...
Thanks again for the suggestions.
One more piece of information: The screws are used to load a ring that presses a piece of sheet metal. The sheet metal is stretched about 1300µm. It is the force of the tension screws that provides the stretch.
I checked on the use of heli-coil...
I appreciate your help.
Material Type is 420 stainless, HRc38 and more than one full diameter of thread engagement. Does this change anything? Ni Anti-Seize was being used "once-in-a-while."
Thanks again,
Mike
We have a stainless steel ring, that has 30 threaded through holes. Into these holes we place set screws, and the set screws are used to apply a load to an inner ring...used for clamping another machine part.
The ring is stainless, and the set screws are nickel plated. These screws are...
