Traditional "kisage" technique
Kisage, or hand scraping, can attain a level of flatness beyond what machining can provide.
Kisage is used to make all major mechanical components exceedingly flat, delivering high-precision machining over long periods of time.

What is “Kisage”
It is possible to maintain the accuracy of the joint over the long term.
Maintaining precision of fastening parts
Maintaining precision of fastening parts
against each other. Stress on the surface, however, causes deformation, which will gradually degrade initial precision. Kisage, also known as hand scraping,makes it possible to heighten flatness so components meet flush without forcing, ensuring long-lasting precision.



Improved precision on sliding surfaces, lubricating and protecting
Operating precision on sliding surfaces is critical in machine tools. The smoother the surface, the higher the precision, but the wringing phenomenon※ can cause the surfaces to seize to each other.
Kisage is used to adjust smoothness to create depressions where lubricants can pool. The enhanced lubrication prevents seizing, lubricating and protecting sliding surfaces.



- *Wringing : When two mated surfaces are excessively smooth, they can seize and become difficult to separate from each other again.
