Nathan, do you guys have any chiller’s on your equipment to keep spindles and what not cool?
Yes, they all run a really thin oil through the spindle casing and through a refrigeration system. The machine has thermocouples in different areas of the casting to compensate for machine growth from temperature and to dial in that coolant temperature. The Makino has a 20,000 RPM spindle, which is on the high end for a cat 40, so the spindle chiller unit on it is the size of a small refrigerator.
