MICRON MACRO-SK Flexible CNC grinding center for Creep Feed-, Profile-, and HEDG grinding CUSTOMER BENEFITS The MACRO Philosophy The “Macro” machine range is based on the innovative Moving-Wheel-Head (MWH) concept. All linear movements when positioning and grinding are performed by the grinding head. Compared to conventional moving column and moving table concepts this design arranges the axes in a very compact way, which results in optimum force distribution and minimal thermal variation, properties which result in best possible process control over a long lifespan. major advantage in this regard compared to other machine concepts, because the cooling lubricant is channeled specifically into the grinding gap, thus achieving larger grinding feed values. The grinding time, and thus the entire cycle time of the process are reduced by having higher grinding feed rates. The maximum stack height in the fixture is approx. 100 mm (3.937”), with the benefit that several stators can be ground at the same time, depending on the component thickness. THE MACRO-SK The MACRO-SK from LAPMASTER WOLTERS is a grinding machine especially designed for machining the internal contours of stators, and it sets new standards in efficiency and precision for machining the internal diameter of stators. The machine concept of the MACRO-SK enables the user to grind various types of stators on the machine, e. g. Gerotor and Geroller. The machine has two spindle arms when fully equipped. During grinding, these spindle arms are lowered in a vertical direction into a stack of stators that are clamped in a fixture. The vertical grinding direction proves to be a The compact, space-saving design reduces infrastructure costs thanks to the small amount of floor space taken up. A completely newly developed acoustic emission system supports precise and economical dressing of the grinding wheels, and is additionally used for initial cut control in order to monitor the grinding process. Optionally, the machine can be equipped with an RFID reader. RFID chips that are integrated into the corresponding fixtures store information about the CNC program number and technology data, for example. As a result, the correct machining steps are performed automatically after the fixture has been loaded. • Compact machine design • Machine only 1.5 m (59.055") wide, small footprint • Vertical grinding technology • Separate spindle arms for roughing and finishing • Differently specified CBN grinding wheels • The vertical grinding direction permits targeted feeding of the cooling lubricant into the grinding gap with gravity assistance • All the stated technological advantages lead to higher stock removal rates and shorter cycle times • Clamping station & handling system • Loading/unloading of the fixtures during machining lead to a dramatic reduction in the cycle time • The clamping station supports precise clamping of the components with repeat accuracy.
