Hardware fails - it's a fact of life... Do Chinese made machines tend to fail more often than their more expensive counterparts? Probably, and it's not just because of poorer construction and inferior parts - it's mostly because the companies never truely test their machines/design - never "run them in" in real world scenarios - test them for 1000's of hours on a line, doing actual assembly, do the things that USERS do to validate the machines. Do things badly to see how they cope, stretch them, abuse them, use them beyond their own expectations for the machines.
Until they start doing that, the "real world" quality level and reliability will never improve.
I cant afford new non "Chinese made machines" - and I'm just not prepared to buy/import a second hand machine I've no experience with, and then have to deal with other new and unexpected issues that all entails. The key here is to go in eyes wide open when buying Chinese machines.
I've decided I'll continue to use Neoden machines (I'm putting in a second N8 on my line to eliminate my PnP as single point of failure) - and I'm putting in a new Neoden IN12C (using my current IN6 as a fallback to eliminate that single point of failure) and from now on I'll treat them as a disposable item - Buy a machine and expect it to only last a year, and that's what I budget into my production line up keep. Sounds crazy, but at the prices of these machines, it's still way cheaper than buying alternative "non Chinese" machines. If the machine lasts 18 month or 2 years, I'm even further ahead.
Still dreaming of buying a Juki RS-1R though ... but it's just a dream!
