(Z axis)

All linear guideways(X,Y,Z) are double-V ways unlike traditional machine tools.

Usually, only coordinate measuring machines are built with double-V ways.

Meticulous hand scraping on all Mitsui Seiki double-V ways assures ultla-precise geometric alignment. 

Final hand lapping results in perfectly mated surfaces for long term volumetric accuracy.

 
 
    The table surface which is the primary surface for machining and alignment verification is also hand scraped to obtain perfect flatness.
