I'm not normally one to have bleak outlooks as the type of person who always finds a way to fix/solve a problem but this is ridiculous and getting worse at an exponential rate.
I work for a heavy equipment manufacturer and things are starting to look dire. It isn't for lack of busy either...we've been pushing at maximum capacity now for months. I run a very large CNC Mill
It started being noticeable last year in the supply of steel. Some stuff was backordered but we still had it in a week or two. Then around 8 months ago specific plate or round stock needed was putting some jobs on hold for a couple months until we could get the raw material.
6 Months ago: Main stream production materials from normal suppliers started getting intermittent with long backorders. This caused the company to start getting material from any source that had it in stock so as not to bring production to a pause. What we got was material of reduced quality or sizing compromises that caused additional work to be required. Tube stock with smaller ID, metal with impurities, plate that has to have the mill scale ground off before it can even be welded properly....
3 Months ago: minor substitutions started being required to complete jobs because the spec'd material was unavailable in reasonable time frame.
2 Months ago: I notice that the tooling inserts cabinet is looking low on supply. Worst of all its the inserts that get used on most of the mills for finish boring anything between 1.6 and 3.0" holes. I voice the lack of inserts to management and get told that it'll be looked into. A week later I get informed that those inserts are a month back ordered.
1 Month ago: Myself and another machinist have been hand re-sharpening inserts just to get by. That back order shipment of inserts (we wanted 5-6 boxes of 10).....we got 10......that right 10 inserts total to supply 3 machines that used that insert daily. A week later I get some larger radius inserts that I asked for the previous month to combat the poor quality material that rapidly chipped the normal insert. Even more raw material is unable to be come by. And to top it off two mills and lathe run their coolant barrels dry within a day. Where are the fresh barrels??? Back ordered as they were ordered over a month prior.
This week: Raw material quality that we can get is causing problems across the board in machining, the insert supply has been exhausted and I'm now using the wrong bit style for the job just be able to do it at all...huge time increase for ok results. I complain to/notify management and get informed that they are "literally scraping the bottom of the barrel" to get any raw materials. In fact...for some stuff we are now forced to get solid round stock and drill/bore the works to the sizes of tube needed.... Well at least the coolant showed up, 4 out of 6 barrels ordered. I've only been putting strait water in the machines for over 2 weeks just to keep running parts. Then have a disaster of a day with breaking drill inserts left and right. Gave up and reprogrammed the part to use a different tool, later find out that the material was substituted for something else we had...which is also significantly harder. Even more hours of labor and cost added... Oh and more inserts you ask? Suposedly there's a "few" on the way from Germany of all places...
A quick Google search comes up with several articles about rapidly shrinking steel, stainless, and aluminum stock piles on top of even bigger reductions to global production. How TF is demand high as ever but production is being reduced? This isn't even and "overseas" problem as the Taconite mines near me just went into a 6 month idle for a "claimed" cost of production/reduced demand reason.
If this continues manufacturing production could come to a screeching halt because we have no material to build anything.
