Serious manufacturers aim to maximise their spindle hours: the green light on the three-colour signal lamp must be lit as much as possible. Green Light Machining stands for process optimisation in machining production. That calls for systems that ensure that the process continues uninterrupted (less down-time), the number of spindle hours increases, the quality is maintained at a consistently high level and productivity rises!
The modern-day metalworking industry is increasingly accurate, often using unmanned systems.
The accuracy of a machine is largely determined by its thermal stability, which is influenced by the ambient temperature and the temperature created by the chipping process and the machine itself. The heat generated by the cutting tools and the chipping process warms up the cooling water and therefore eventually the machine as well. A cooling chiller maintains the cooling water at a steady temperature, thus keeping the machine dimensionally stable.
