Looking for clarification on the surface finish symbol on this print. I know the purpose of the line at the top of the symbol, but I've never seen it extend to the left. It doesn't look accidental so maybe it has a purpose I'm not aware of?
Thanks. BTW print was originally done in '59.
Dave and Chez, you guys are probably thinking I'm an idiot to keep badgering you on this, but I struggle with some GD&T and how to properly apply/use it in certain conditions like this one. There's a reason why I'm on the productions side of a part and not the inspection side.
I understand...
I tried edit my original post with a new link for a png file of our full in process print but it won't let me and it wouldn't let me add it to the body so here it is. I added clarification on what Datum C is.
Chez, I'm trying to find the p.o. as the spec is sometimes included on this customers...
1st, sorry about the link not being correct. This is how the think was inserted by the attachment option.
Chez311, this is an inprocess print created by our manufacturing engineer, however it is exactly as it is shown on the customers supplied print. Yeah it's a mess.
1) Customers print does...
I just spent some time simulating his process in my CADCAM program, and maybe what he is doing is right, and I just couldn't grasp it in my head without drawing it out. I was thinking that once he meas./found Datum D he could call that "zero" per say, then rotate 120º from the original alignment...
So QC and myself have been discussing the inspection of a part (attached a copy of our in-process print).
QC says that to inspect the part, they origin of Datum B (an OD), square up to Datum A (face of part), then take a hit on Datum C surface. They then rotate thru that point to create an...
A customers print has the following data for an internal involute spline but from what I and the hobbing house have determined is that either the dimensions are labeled incorrect or they are missing. Wondering if somebody could help me out here?
Fillet root side fit
# of teeth - 101
pitch -...
The machine itself is rated for 50/60Hz (motor itself has nothing about that on it).
No speed regulation on motor. The gearbox is attached to a Ø10" plastic disk used to collect tramp oil off the top of the cutting coolant.
Once I verify the output shaft on the motor itself matches, I'm...
Bill, I did come across that website (actually only website I found that has these induction motors) in my search. Since it's an option to purchase this motor already attached to a gear box, I agree that the S5T6 probably has something to do with that (no p/n on the gearbox on my machine so...
HCB, what I was trying to get at almost every machine from overseas is wired for 220, so to have a machine wired for 230/240 would most likely require a U.S. built machine (which is why I mentioned Mazak). And U.S. manufacturers of CNC machines capable of doing the work we do is very small...
HCB, unfortunately there aren't a lot of CNC Machine Tool builders in the US. Mazak being the biggest, unfortunately our budget cannot afford that high of a cost (plus we cannot charge enough per hour to pay for it because our U.S. customers (which is 100% of our customers) wont pay that much...
I'll try to throw up some pics shortly, but here are the specs off the nameplate.
4IK25GN-S5T6
3phase, 4P, 220v, .26A, 1600rpm, 25W.
The only thing really throwing me off is the last 4 values. They don't seem to follow the standard. The closest I can find is a 4IK25GN-SW2T. The S5T6 is probably...
Looks like the motor itself is burned out. It's VGS/Shin BAE induction motor. Anybody now of a good place to get an induction motor? Doesn't seem to be real prevalent on the web. I can get one from manufacturer, but I'd like to find a cheaper source.
Thanks.
Waross, I don't know what the motor itself is rated at yet (haven't had a chance to actually tear it out of machine yet), but the machine itself is rated at 220v 50/60Hz which as you guessed came from Taiwan. I assume the motor itself is from the same country.
No problems with voltage drop...
One of our CNC machines required 220v (+/-10% according to manu.), but the 208v panel was at it's max. load so the electrician wired the machine to the 240v panel and put two buck transformers inline to drop the voltage. His reasoning was the 240v panel was a little over and the manu. was very...
Thanks moon161. trying to find some small cylinders right now and not finding much. At least not as small/ low pressure as I want. Still looking though.
SnTMan, SparWeb you are correct. What I need is basically a small hydraulic cylinder, just need one that I can put in a collet in the Bridgeport. Reason for Bridgeport is the orientation of some plugs is very awkward so we made fixtures to orientate part to Bridgeport spindle so we can use push...
