摘要： A cutter head 22 includes a first member 90, a cutting bit 86, and a second member 94. The first member 90 includes a first end and a second end and includes a first mass. The cutting bit 86 is coupled to the first member 90 proximate the second end. The cutting bit 86 includes a cutting edge rotatable about the axis. The second member 94 is rotatable about the axis and includes a second mass eccentrically positioned with respect to the axis. Rotation of the second mass causes the first member 90 and the cutting bit 86 to oscillate.

摘要： A mining machine (10) including a frame (14), a cutting head (26) movably coupled to the frame (14) and pivotable about an axis (52) that is substantially perpendicular to the first mine surface, and a first actuator (542) for stabilizing the frame (14) relative to the first mine surface. The first actuator (542) is coupled to the frame (14) and includes a first end (598) extendable in a first direction to engage the first mine surface. The extension of the first actuator (542) is automatically controlled based on measurements of at least one indicator of the force between the first actuator (542) and the first mine surface.
