Practical micromachines, such as magnetic heads or endoscopic tools, can not be made only by shaping processes; they require post-machining processes such as assembling, wiring, piping, etc. The authors have developed an integrated manufacturing system, 'nano manufacturing world' (NMW). It performs shaping, post-machining or transferring like a factory. In this paper, we introduce a microwork transfer system, which functions a) steady transfer of a workpiece, b) non-release chucking of the workpiece during production and c) individual rotation of the workpiece using a preloaded microslide bearing on the pallet. Developed transfer system could realize the functions: less positioning error due to accurate pallet positioning by taper pins, high transfer yield of the workpieces due to no missing by a micro chuck, sub-micron rotational fluctuation due to a roller pallet by a preloaded micro slide bearing. Through the fabrication demonstrations of a sub-1 mm3 micro-house or micro force sensor block of 125 X 100 X 500 micrometers , it has been confirmed that this transfer system improved the performance of integrated manufacturing in NMW.
