1. double-channel grinding method of double-row ball bearing is characterized in that:

  • adjust centerless fixture, the axial location supporting of centerless fixture is carried out grinding with the mode of equipment autogenous grinding, and Control Shaft to the end face run-out of positioning support in 2 μ

    m;

    According to the size that is ground lasso---raceway diameter De/di and ditch position a/b, ditch spacing a1/b1, the requirement of the radius of curvature R e/Ri of raceway groove;

    Adjust the angle [alpha] of equipment work-piece frame, the angle adjustment scope is used CNC digital control system switch board again between 0 °

    to 25 °

    , the shape of control grinding wheel arc dresser single-point finishing emery wheel;

    The locating surface that will be ground lasso again is fixed on the centerless fixture, and employing CNC digital control system switch board, while control appliance work rest X-axis and emery wheel, the feed distance of mill frame Z axle, after the locking, rotary electric main shaft and slewing work spindle drive and are ground lasso, make emery wheel enter the first row raceway groove and carry out grinding;

    After the first row raceway groove grinding is finished,, emery wheel is fed into the secondary series raceway groove by the CNC digital control system, and locking, grinding secondary series raceway groove.
