Abstract: The axial rotation of a honing tool head and the radial advance of the co-rotating honing stones are accomplished simultaneously by a magnetic coupling. The magnetic coupling connects an inner and drive axle that are driven independently. When the inner axial is driven at a differential speed than the drive axle, a connected pinion gear mechanism is engaged to transfer torque and radially displace the honing stones in response to the speed difference.

Abstract: Provided are a polishing composition for chemical mechanical polishing, a method of preparing the polishing composition, and a chemical mechanical polishing method using the polishing composition. The polishing composition which is a water-based polishing composition for planarizing a metal compound thin film including two or more metal elements includes nano-diamond particles as a polishing material and poly(sodium 4-styrenesulfonate) as a dispersion stabilizer for the nano-diamond particles in the polishing composition. Since the nano-diamond particles in the polishing composition have hydrophobic surfaces and poly(sodium 4-styrenesulfonate) effectively stabilizes the nano-diamond particles to prevent the nano-diamond particles from aggregating, excellent polishing characteristics for the metal compound thin film may be obtained due to the nano-diamond particles which have a nano size, high hardness, and excellent dispersibility.
