I once bought a used 80 ton hydraulic press from Levi's. It was used to cut blue jeans, cotton fabric dust everywhere in it. It used maple plywood and die rule cutting dies that could produce 1000's of jeans pieces a day, (polyester/cotton fabrics are a bitch to cut). The dies could be swapped in a few minutes and rebuilt in about an hour with simple tools. The cost of the dies were about $1000 US and could last up to a year.
Those hand operated cutters are fine for simple items made in small lots, but you want to make millions? They are useless.
*I rebuilt it to cut sandpaper discs and sheets using similar die rule dies that could cut 3000 to 4000 pieces per rebuild.
You don't layout your fabric on long table. You feed it from a 5000lbs roll with an automatic indexer and then die cut it. One operator can do the job start to finish. (Been there done that as a toolmaker who made some pattern die rule dies for Levi's and then bought and rebuilt an 80 ton hydraulic press from them that had whacked out blue jeans every day for 20 years and rebuilt it to cut sandpaper discs for the next 15 years)
The CNC cutter is valuable for a company that does custom cutting work for outside customers rather than for in-house work. Fast to make changes with minimal setups. But prepping the material to feed the machine is more labor intensive.
