Are Fanuc Drives Still Relevant?

Yes, Fanuc drives are still relevant in today's industrial automation and motion control applications. Fanuc is a leading manufacturer of industrial automation equipment, and their drives are widely used in various industries such as automotive, aerospace, electronics, and more.

Fanuc drives offer several advantages, including high reliability, precise control, and flexibility. They are designed to work with a range of motors and offer advanced features such as torque control, speed control, and position control.

Moreover, Fanuc drives have been developed over the years to keep up with the changing requirements of the industry. They are available in various models, each designed to meet specific application needs, including AC drives, servo drives, and spindle drives.

Overall, Fanuc drives remain a popular choice for industrial automation and motion control applications due to their proven track record of reliability and performance, along with their advanced features and flexibility.

I haven't seen a Fanuc drive factory installed in any of the new equipment we bought that's why I asked but apparently Fanuc is still kickin'

The Maintenance Saloon / What is a Schmidt Trigger?
February 07, 2018, 04:09:AM
Hello,
What is a Schmidt Trigger? I have a position feedback device on the end of the x axis table on a milling machine that hasn't been accurate for a while. I tried swapping the x and Y axis feedback devices and the problem stays with the x axis so it is not the encoder (or whatever type of feedback this is). The machine is old but it doesn't appear to be this unit.

I spoke with the previous owner of the business and casually mentioned the problem. He said it sounds like I've got a bad Schmidt trigger circuit. Any thoughts on this?

Thanks!

Thanks for posting the troubleshooting tips, they may come in handy down the road. My problem at the moment all lies within the tape reader. It just ignores the tape and feeds it through.

The Maintenance Saloon / Vintage Machine Tools
November 06, 2017, 09:02:PM
Hello guys,
Anyone into vintage machine tools here? I've got a few older stamping presses, lathes, drill presses, and milling machines in my shop.

I like to keep the older machine tools running versus replacing them with imported machines of today. Anyone here share my passion for vintage machine shop equipment? I'd like to see some pics if you've got classic machines that still run.

Troubleshooting 101 / Pratt and Whitney Tape-O-Matic
November 06, 2017, 08:57:PM
Hello guys,
I know this is an industrial long-shot, but does anyone have technical info or a service manual for any of the old Pratt and Whitney Tape-O-Matic equipment. I have an old tape-o-matic machine with a lot of tapes.

The machine is rock solid and hasn't been used in years. I'm hoping to resurrect this system with any investment right now. I can invest money into a controls upgrade as early as next year, but for now I'm hoping to get the tape portion of the control working again.

The tape reader won't read the tapes, reels turn but the tape just feeds through and the controls don't respond. All the servos on the machine work fine in manual mode.

Any tape-o-matic tech support would be greatly appreciated. Thank You!
