The JUCENTER CBN high-speed grinding machine combines mutually complementary grinding possibilities under one hood. Instead of lining up individual grinding machines for different grind-ing tasks, both grinding processes take place in two separate clamping set-ups on one machine. The result: highly efficient grinding – all with top precision. Highlights Faster production time High process reliability Low overall investment Low space requirement Low operating costs Less man-power required Controlled dimensional accuracy using in-process gauging Controls with “Learning Function,” including automatic compensation of roundness deviation and dimensional errors High long-term accuracy with hydrostatic circular guides (X-axis, infeed spindle, axial bearing) Uncoupled processes Gear shaft grinding At station 1, JUCENTER grinds plunge-cuts and faces in a high-speed gear shaft grinding process. With the help of a B-axis, the grinding spindle can be swiveled to grind plunge-cuts, as well as faces with very fast cycle times. In station 2, multiple-bearing grind-ing of all centric diameters takes places In station 1, CBN multiple-bearing grinding of all centric diameters (bearings and pivot) takes places. Parallel to this, other grinding carriages in the next clamping set-up (station 2) carry out non-circular grinding - that is, the grinding of main bearings. This is done using the pendulum grinding method with separately controlled CBN grinding wheels. Depending on workpiece-specific factors, workpieces can also be run in the opposite direction (from station 2 to station 1). In station 1, sets of bearings are ground with one plunge-cut, using multiple-bearing technology.
