Hello all. I hope this is the proper place for an introduction. Anyway new guy here I'm only 28 so a young guy. I spent the last 7 years working in a small machine shop/foundry that makes bronze bushings. My first 4 years I ran a couple of Warner & Swasey 2A's and a 4A depending on the job at hand, also ran a few other smaller conventional lathes. Most of the work was just straight turn and bore, but there were some O.D. and I.D. grooves and chamfers from time to time. I had to learn to do my own set ups and do my own final inspections. The last 3 years I ran a Haas VF4 CNC mill and a Haas ST30 lathe. My dad was the companies programmer and the time and while I had to learn to do minor edits I am in no way a programmer but I had to do my own setups and final inspections on those machines too. For the past 8 months I've been working at the local Timken plant running 6 Heald 1CF90 I.D. grinders, I originally trained on the 0CF90's and then was moved to the 1CF's. Our plant has 50 1CF90's and 18 0CF90's. The 18 0CF's and 42 of the 1CF's run 2-3 shifts a day 5 and 6 days a week. The other 8 1CF's are currently being rebuilt by our machine repair department. 3 of the 6 that I run on a daily basis were just rebuilt a year ago. The other 3 were retrofitted by SNI about 10 years ago and I personally do not care for them.
Myself I find these old machines fascinating and want to learn more about them. There seems to be very little online overall about the Heald Machine Company and especially the Controlled Force series of I.D. grinders. I was hoping maybe somebody here could point me in the direction of some reading material? Maybe there's some online repair manuals somewhere I could check out or maybe someone has some stories about these machines? Or pictures of them installed and running? All but 8 of the currently running 1CF's have Allen Bradley touch screen controls, the other 8 and all of the 0CF's have some older form of control I'm not familiar with they have a keypad input and screen for certain operations but it is only a two line display. Would all of these machines originally have run on punch tapes? As I undertand it all of these machines have been installed in this plant since it they were purchased new, and have just been retrofitted over the years. Thanks in advance for any info.
