APPARATUS FOR CUTTING AND GRINDING A WORKPIECE

摘要

A machine for simultaneously milling and grinding a workpiece comprises milling and grinding wheels rotatable about respective first and second parallel axes, the second axis being offset radially with respect to the first axis. A single motor drives the milling and grinding wheels at different relative speeds. The grinding wheel is mounted to a hub which includes an axially flexible portion to enable the grinding surface to be axially adjusted. The milling wheel includes an array of milling cutters with a large gap formed between leading and trailing ones of the milling cutters to accommodate the offset grinding wheel. The radial spacing of the milling cutters from the axis of rotation of the milling wheel progressively increases from the leading milling cutter to the trailing milling cutter.
