Granite Components (Granite Machine Components)
For years, we have been dedicating the manufacture and quality control of  granite components, and have got some achievements in this field. Please find some pictures of them below: (click to enlarge)





As a granite manufacturer, maybe it is not difficult for them to assure flatness, perpendicularity or parallelism on a certain set of components. The question is that how to ensure the position tolerance of holes, while in most circumstances there are many on granite components and requiring higher position tolerances. In long there is no certain rules or instruments to measure the holes positions. But now we have got a real solution about this. For a special instruments have been invented by us after years of bending on holes position tolerance researching.
