good afternoon all
I have a 2011 Haas super mini mill 2.
I was experiencing issues with turret rotation faults where the tool in position sensor seemed to be experiencing intermittent problems. It seems as if coolant had run down inside of the inductive sensor. Due to the lead time on a new sensor and work needing to be done I swapped the tool 1 sensor and the tool in position sensor. My reasoning behind this was the tool 1 sensor is used on startup to reference the carousel and I assume it is used if I call tool 1 so I thought use the sensor that is not faulty for the tool in position check. By the way the sensors have different part numbers but they are identical according to the spares guy.
All of this worked well until recently when I had a turret rotate fault, took off the covers to check and everything started working again. 3 days ago I did a tool change and the machine attempted to do a tool change with the tool out of alignment with the spindle, I assume the tool in position sensor sent a signal when it shouldn't have. I called the local Haas repair technician who said he hadn't seen this in 10 years of working on Haas machines. As I am pressed for time I got him to come over and replace the sensors that I had bought from Haas. When he ran the tool changer the same thing happened. We replaced the 2 sensors and ran the tool changer through a couple of cycles, nothing out of the ordinary.
My question is, has anyone else experienced this before. I am now very reluctant to run the machine unmanned just in case something goes wrong again. According to the Haas technician there is no overload detection and if this happens again the carousel will be damaged.
Any help will be appreciated.
