(1) feeding and overall compensation skateboards are highly rigid box structure, the use of high-precision AC servo motor and ball screw feed mode, high-precision machining, product consistency, feed stable and accurate; rails and screw centralized lubrication system, regular quantitative filling oil.
(2) within the three-axis control raceway grinding, plunge grinding; dressing dressing system through two-axis interpolation carried out.
(3) outer raceway grinding wheel and workpiece feed back and forth using two-axis control, servo oscillation amplitude and frequency of coarse and fine grinding automatic adjustable; dressing bearing two-axis on a logarithmic curve operation, the grinding roller cut into decline when the oscillation grinding, grind the outer raceway to ensure logarithmic convexity shape.
(4) sets Simple workpiece spindle structure, AC variable frequency motor drive, variable speed, coarse grinding speed is automatically adjusted.
(5) using high-speed grinding wheel speed 60 m / s. Inner raceway grinding wheel spindle and using static and dynamic pressure balancing device, outer raceway grinding with high rigidity, high-power electric spindle.
(6) Rotary arm manipulator automatic loading and unloading, electromagnetic centerless fixtures, high rigidity ceramic support structure. Support means for the mill are expensed inner raceway raceway grinding, grinding mill outer ring raceway diameter branch.
