High-speed bearing machining method and device

The invention discloses a machining method of a high-speed bearing. The machining method comprises the following steps that S0, material preparation is conducted, specifically, a pipe is cut into a blank piece through cutting equipment; s2, rough turning is conducted, specifically, a lathe is used for conducting turning on the blank, and the basic appearance is turned; s3, semi-finish turning is conducted, specifically, the workpiece obtained through machining in the S1 is clamped, and semi-finish turning is conducted according to a drawing; s4, finish turning is conducted, specifically, the machined part obtained in the S3 is turned to the drawing size, and the height error of the outer circle diameter and the inner circle diameter is controlled to be within the range of +/-0.05 mm; s5, heat treatment is conducted, specifically, the product obtained in the S4 is put into heat treatment equipment to be machined, the process comprises quenching and tempering, quenching is conducted by heating to 780-800 DEG C,
