Disco NCPZ-010019-20 Spindle Repair & Rebuild
We received this Disco NCPZ-010019-20 Backgrinding spindle from a local company that manufactures highly innovative analog semiconductors for countless applications. Prior to sending the spindle in, the customer notified us that the only problem with their Disco Backgrinder was coolant restriction. Because the spindle itself was mechanically sound, we worked at eliminating the restriction without taking the spindle apart. Unfortunately our best efforts were met without success. So the spindle had to come apart. With the spindle apart we were able to observe the severity of the blockage. All coolant porting was closed off with what looked to be rust and other debris.
After clearing all of the coolant lines and porting, the air jets within each bearing were also cleared of obstruction. All seals were replaced with new chemical resistant O-rings. After pressure checking the coolant circuit we ran water through the circuit and verified that the flow was within the specified OEM specification. With the coolant restriction eliminated, we test ran and balanced the Backgrinding spindle up to max speed. It passed all testing and the customer was happy to receive the spindle over a week earlier than expected.
