It's one thing to have the door locks working when you can see what is happening inside the machine but we have several lathes that the glass is so beat up that you can't see a thing so we have to disable the door interlocks. I don't know how your company works but at ours we have a better chance of getting a new machine than in fixing the old one.

My Okuma LB-15 has a door interlock system. I replace the glass every 2 years or so. Never a problem setting up and I've worked on this machine since it was new in 1983. Glass for machines is usually not expensive.
