Knowns:
D2 tool steel Sleeve (Rc 62)
4140 Shaft (Rc 28)
This is a fairly large part and the interference fit is calculated/specified to be 0.008"
Problem Statement:
Have had (2) issues: (1) the sleeve cracked (like an eggshell). I assume it's due to high stresses since the D2 sleeve is heat...
Problem Statement:
I have an whole-house dehumidifier (Aprilaire 1770A) that can be used to duct (8" diameter inlet/outlet) to specific locations in a dedicated area. In other words, i am using this dehumidifier for my crawlspace (1,850 sqft) and i need to duct (both for the supply and return)...
Does anyone have any experience to cryogenically treating carbide? What grades of carbide are more suitable for cryogenics? I am looking at optimizing our tooling wear within our progressive stamping department.
Thanks in advance for your help on this,
Andy
