摘要:
A cutting head for hard rock mining applications is disclosed. The cutting head may have a base member. The base member may have a rotational axis and may include a center bore extending along the rotational axis. The cutting head may also have a drive bushing disposed within the center bore. The drive bushing may be configured to transmit torque from a driving device to the base member. The cutting may further have a plurality of annular tool supports. Each of the plurality of annular tool supports may be concentrically disposed about the rotational axis in a releasable manner. In addition, the cutting head may have a plurality of cutting bit carriers attached to each of the plurality of annular tool supports. Each of the plurality of cutting bit carriers may be configured to rotatably support a cutting bit.
