<p>A spindle assembly/main housing apparatus (10) is provided. It comprises a spindle assembly (20) including an outer casing (22) and a tool spindle (24) rotatably mounted within the outer casing (22). The tool spindle (24) has a first tool supporting end (24a) and a second end opposite the first end. The outer casing (22) has first (22a) and second (22b) ends. At least one first O-ring (52) is positioned about the second end of the outer casing. A main housing (30) is further provided and has a central bore (31) in which the outer casing (22) is housed. One or more connectors (40) couple the outer casing first end to the main housing (30). A first section of the outer casing adjacent to the first O-ring defines a first gap (G1) with a first section of the main housing opposing the outer casing first section. The at least one first O-ring has a sufficient diameter and a sufficient material stiffness and the gap has a sufficient width to attenuate a substantial amount of vibration occurring at the outer casing second end relative to the main housing.</p> |
