External hone

Apparatus for externally honing a fixed workpiece having an axis comprising:

• a support assembly;
• a honing fixture defining a honing axis and including a mounting structure carried by said support assembly, a rotatable structure carried by said mounting structure for rotation about said honing axis, and means carried by said honing fixture and coupled to said rotatable structure for applying a torque to said rotatable structure such that said rotatable structure rotates about said axis;
• a plurality of honing stones connected to said rotatable structure for rotation therewith about said honing axis and for engagement with a workpiece for honing the external surface of the workpiece;
• support arms coupled to said support assembly and said mounting structure on opposite sides of said honing axis and independently pivotal relative to one another;
• and
• biasing means enabling said support arms to pivot in substantially equal increments in opposite directions in response to an applied torque whereby any tendency of said honing fixture to be displaced laterally in response to said applied torque is resisted by said biasing means.
