Use pH, concentration, bacteria, tramp oil, odor, chip load, sludge, and sump inspection results to estimate when a CNC coolant tank should be cleaned. This guide explains what coolant tests reveal, what they miss, how sump contamination affects part quality, and how a sump vacuum workflow helps recover usable coolant without returning it to a dirty tank.
Choosing the right sump vacuum for your CNC machine shop depends on what you are collecting, how much coolant is in each tank, and how your shop operates. This guide breaks down the key factors that affect sump vacuum sizing, coolant recovery, tank cleanout speed, and overall shop efficiency.
