Accessories Rotating Coolant Union

Available on all ProMetrix series super precision spindles.Rotating coolant unions allow the coolant to enter by way of the rear of the spindle shaft and flow through the spindle to the tooling. Requires hole through and machining of spindle shaft to accommodate mounting of the union. Available as straight through or 90Ëš union.

Air/Oil Metered Lubrication

Air/Oil metered lubrication is available on all ProMetrix series super precision spindles. Used mostly on highspeed spindle applications where the ‘DN’ value is greater than 500,000. Arrangement for air/oil metered lubrication consist of machining of the spindle housing and outer bearing spacers for directing the air/oil lubrication precisely to the bearings. Requires very little oil consumption. The high volume of air provides additional cooling of the bearings.
