Hello!
I am in need of some advice for heat treating small batches of stainless steel components. I currently own a Thermo Oven ( http://www.labdepotinc.com/Product_Details~id~93~pid~60628.aspx?gclid=CPjX866_wLcCFYhAMgod1mEA5w ), but this one doesn't have enough horse power to perform the H900...
Thanks for your help resolving this issue!
One last questions: any recommendations for GD&T reference/self-teach guide?
I searched this site and found a few ideas: YouTube videos, some older "textbooks", etc., but you all seem very knowledgeable so I thought I would ask!
Thanks again!
Thanks for all your helpful replies. It has been very informative for me. Attached is what I've come up with, in light of your responses.
Thanks again!http://files.engineering.com/getfile.aspx?folder=e21ade6d-0831-4816-bb9f-950d2418b1f1&file=Updated_with_GD&T.png
I'm having some issues keeping a feature on center. Can you please look at the attached image?
I need a good GD&T call-out to keep these features on center. First move is to add a center line to this print and I’m assuming adding a datum. I would like the .563" thickness to stay on center...
"there are two different sized holes gun drilled from opposite sides. The larger one is a datum and the smaller one references it for runout, position, etc. I'm assuming this part mates with something that also has a large and small diamter that mates inside. From what has been commented so far...
The customer actually forgot to put it on the print, part of the reason we had this issue in the first place (ugh)
They do have a .006 run-out tolerance from the smaller ID to the larger ID (the larger ID is the datum referenced)
Thanks for asking for clarification; in a nut shell, I need the...
I am inquiring about the H900 heat treat process. We are validating our heat treat oven and running into an issue with getting them up to temperature.
Here's my protocol: 6 thermocouples places on a fixture that record the temp at the level in the oven where our parts sit during H.T.. The...
I am machining a 16" cannulated shaft (.75 OD). There are 2 IDs which are gundrilled separate from each side and meet in the middle. I am having issues with the holes lining up, concentrically, where they meet in the middle. I am allowed a .006" tolerance on concentricity. Our machines are...
Thanks for the replies!
Yes, there are heaters. We already wait 1 hour for the presses to get hot, so I don't want to wait any longer.
These buck-booster, will I need one for each machine?

Mechanical engineer here. I have 8 hydraulic molding presses in my facility for over-molding silicone. We're moving them to a new building that runs 208V power supply. These machines have a call out on the side that says "240V 60 AMP" Can these run safely/efficiently on 208 V or do I need an...
Thank you all for you responses!
MintJulep, I think the belt/pulley system will work well in retro-fitting my current set-up.
I need to carry 4 lbs of weight up the 3.5 ft. Assuming my pulley is 4" dia. I will need a motor to supply 24 ft-lb of torque. I found a website called...
I am trying to perform a test to mimic the impact of a hammer onto the back of a screwdriver....many times.
I want to run the test until failure of the screwdriver or 5000 cylces, which ever comes first. My fixture will need to supply the force of a one pound steel weight dropping 3.5 ft (or...
