An automatic two-axis die cutting press uses a die board with steel knives to cut leather on a nylon board. Below the nylon board, which is usually 1/2" thick, is a base plate made of metal, usually 1/8" thick.
The head of the press usually works in the center portion of the press, exerting up...
Did a search on this subject here on the site, and the closest I came to was this thread, but not the answer I'm looking for: http://www.eng-tips.com/viewthread.cfm?qid=39095
My question is simple. A 3HP 240VAC motor with appropriate VFD drive running at 60Hz continuously 8 hours a day, without...
Trying to compute consumption of electric power for a 3 phase machine, which has an average currents of on a continous basis, as measured with a current loop ammeter:
phase 1 = 16A @ 120V
phase 2 = 16A @ 120V
phase 3 = 8A @ 208V
We had an electrical fire in a heater controller enclosure today, where a 5 Amp fuse was disintegrated!
The 5 Amp fuse was in a block of 4 fuses, from left to right >>20A>>20A>>5A>>5A. The 3rd fuse from the left.
No breaker was tripped. The fuse just isn't there any more; it's all carbon...
Mind boggling thing, which is above my head to understand. Did a search on the forum, but couldn't find anything as crazy as what's going on with my system.
I have an AC drive and a continuous duty motor. Controlled by a few sensors, the motor starts on command, and stops when it reaches end of...
I'm not quite sure if this is the appropriate forum for this question, but I'm sure I'll be guided.
I would like to open a discussion today with the following question: in an automated assembly line, where a stand-alone automatic machine assembles 30,000 parts a day, how many fault stoppages...
Did a search in a few forums but came up empty handed.
Using a Festo vacuum module (13 CFM) (with its own blowoff system, and internal solenoid valves) in a very dusty environment. Even using a 40, 50 and recently 10 micron inline air filters, the vacuum modules are still malfunctioning, due...
I'm sure anyone (but me) her on this forum can answer this basic question, which has bugged me for years [ponder].
If a system is powered by 220VAC, are you saving money from usage of electricity over a similar system that runs on 110VAC ?
Similarly, will you be saving money if your system is...
Hello all,
Similar to a previous post here, I have an obsolete SYSMAC (Omron) PLC from the late 80's on a brake and clucth operated punch press (25 TON).
I have vast experience in programming PLCs, but haven't done any programs for punch presses. As part of preventive maintenance I'm being...
Hello,
For some readers this may be a repeat, as I have posted this message on other forums as well.
I have a machine from the 80's that has a SYSMAC S6 PLC.
It appears that there is a problem with the PLC and needs to be replaced. The manufacturer does not make or support this PLC. Hence, I...
As my subject header suggest, I have a "regulted" power supply 110VAC in 24VDC out, but measuring the + and - terminals on the output, I am getting 40VDC.
Does this mean that my power supply has gone bad? What could cause this?
Thanks
Very basic question: does hardening (case hardening) change the tensile strength of the metal.
The metal is a rotating shaft out of Leadloy.
How about hardening the whole thing? Does its tensile strength change by doing that?
Thanks.
Hello,
I can't seem to find the answer to this one.
I have a 1/4" rotating rod (12L14 Steel) extended 2" out of a double angle collet. At the tip of the rod I have a metal disk with dimensions 3" round, 1/2" thick and weighs 4 oz.
How can I determine a theoretical safe...
Since the installation of a large forced-air convection oven in the plant we've been concerned with the amount and temperature of heat the employees are exposed to every time they open the door to the oven. The frequency of opening and closing the door is every 30-60 seconds, and the maximum...

We own a 20,000 sqf building (roof size), on which we are interested in laying solar panels. These panels are formed of thin layers of nylon sheets with solar cells on them and they become part of the roofing and water proofing.
The technology is new and may be cost effective, depending on the...
