Abstract
In lapping of steel balls, the influence of the groove depth of laps on the waviness of balls is analyzed experimentally. Five grinding wheels with different groove depth are used as laps. A shallow round groove is equivalent to a V groove with a large angle. A deep round groove corresponds to a V groove with a small angle. Experiments show the following results : The low-order-waviness is improved when both the fixed lap and rotating lap have deep grooves. The medium-order-waviness is improved when the fixed lap has deep grooves, while the rotating lap has shallow grooves. The high-order-waviness is also improved effectively when the grooves on the fixed lap are deep, and the grooves on the rotating lap are shallow.
