Hello all.
I purchased a Hardinge CHNC II from a local auction about a year ago, got it set and wired up and it powered up and ran fine aside from the E-Stop Reset button not working.
Upon first starting the machine, I am having trouble getting the E-Stop Reset switch to function. It lights up and blinks. After a combination of resetting the 2 E-Stop buttons, pushing buttons and moving around on the screen, and pushing the E-Stop reset button a bunch of times, it will finally function.
I have pulled the E-Stop button switches from the panels and cleaned and checked them and they are working fine. I also checked the contacts from the E-stop reset button to the circuit board and they seem fine.
I also checked the door open switch, the air valve circuit and the lube circuit. All fine.
Anybody else experience this issue?
This machine has sat for about a year without being touched since my first time powering up the machine.
This past weekend I fired it up, and I keep getting this alarm message: 'SV008' - X Excess Error (Stop) Alarm
When I reset the alarm, the X-axis will 'jump' a touch (as viewed front of the machine with the front X-axis ball screw cover off), and then the machine alarms out, repeatedly.
After some investigating (removing covers, etc...) I noticed when jogging the x-axis, it stutters, and I believe this is what is tripping the alarm, maybe something mechanical?
I have topped all of the oil reservoirs off, removed the bellows on the back of the cross slide, and the ballscrew is shiny and oily from what I can tell.
When moving the x-axis on the forward side with an allen wrench in the end of the ballscrew shaft, I feel some resistance and what feels like 'steps', could be the cog belt.
I am a little gun shy about pulling the servo/belt to see if the isolated ballscrew still hesitates.
I'm not sure what could've changed in the past year this machine has sat.
I have researched this website and other forums and have found myself stumped.
Has anyone had this issue before? Any ideas?
I am more than happy to let a professional look into these issues. Any recommendations for machine tool repair in the Kansas City area?
Thanks in advance.
