We have 5 Haas SS verticles. 2 VF4's and 3 VF2's. We machine cast iron. We are experiencing some serious problems with the TSC systems. Seems as though our coolant, Eco-cool from Fuchs is eating away the brass-bronze check valves in the TSC system. This is allowing the coolant to back feed into the air system, and the drawbar cylinder. Causing tool changer faults and electrical problems.
The way lube lines are a copper based alloy?? They are basically being corroded away. When the tech took the way cover off the tubing was covered in a green fuzz. These machines are only a yr old.
Haas has commented that this is a coolant problem and don't seem too concerned. They have replaced the check valves on 1 machine with more brass ones. Has anyone had similiar problems?
All our Matsuuras don't seem to have this problem with the coolant.
