MCK8011 machine applies to all kinds of current CRH high speed trains, which can be used for machining the wheel tread profile of wheelset as well as the wheel inside and outside surfaces and axle disc (inside/outside surfaces) without disassembling brake disc and gear box after dropping the wheelset, the wheelset has axle-load and wheel-load brake discs under the condition that without dismounting the bearing and axle box (but the axle box cover can be opened). For example, the machining and repairing operations can be carried out on the brake disc and wheel flange surfaces of the wheelset on high speed trains and trailers.
