brake disk grinding

摘要

A resurfacing method and apparatus for brake disks or rotors and for flywheels utilizes "dead centers" to support the rotor, flywheel or the like, avoiding disk thickness variations which would result from support of the disk or flywheel on roller bearings. Abrasive grinding wheels are used to effect the resurfacing of the disk, rotating in such a way relative to the disk rotation that a desired, long-wearing surface pattern is produced on the disk or flywheel.
