The advent of high speed, accurate and precision machining requires thermally stable and precise temperature control of the spindle and ball screws in a CNC machine. Advance Precision Chillers with variable speed compressor and “twin” valve technology ensures that the oil/ coolant is maintained at a precise control within tolerance limits of+ 0.1 D eg C. The special PID algorithm adapts to every load condition and ensures stable tern peratu re even in Zero Load conditions. Th is resu Its in highly accurate and precise machined components.
