    Haas DS30 Y BMT Turret Bearing Failure Due To Rust After 7 Months ???

    We purchased our lathe about 7 months ago. 2 weeks ago, the turret stopped clamping in one position. The Haas tech disassembled the head and found the turret rotation bearings had rust mixed with the grease. It appeared coolant had leaked into the turret bearing through two proximity switches which sit under a cover between the turret and the head. We were informed by our HFO that Haas will not warranty the machine because the rust may be caused by having an incorrect coolant concentration. I believe the turret bearing assembly should be seal from the factory to prevent contamination. We are worried this could occur again. Has anyone else had trouble with coolant entering the turret bearing housing on the new BMT turret, or with warranty being voided due to rust?

    I would fight Haas and HFO tooth and nail over this, coolant shouldnt be mixing with grease.
