The use of granite V-shaped rack: is used to support shaft, tube, sleeve cylindrical workpiece, the workpiece axis line parallel to the platform face in order to find and crossed tools. Granite V-shaped frame made of high quality "Jinan Qing" natural granite material machined, hand-lapping from. Black gloss precision, structure, texture, uniformity, stability, granite V-shaped frame has: high accuracy, no rust, acid and alkali is not magnetized, the same type, and good wear resistance. In heavy duty and general temperature remains stable. 
 Granite V-shaped frame material quality of the rock layer on the ground after millions of years of natural aging, form extremely stable, do not worry deformed due to the conventional temperature difference. By rigorous physical testing and selection of granite materials, fine crystalline texture. The granite of non-metallic material, no magnetic response, and no plastic deformation. 
 Granite V-shaped rack is better than the precision measurement of high-quality cast iron and steel production base parts, to obtain high and stable accuracy. I produced the marble V-shaped frame, the resting place for a year to maintain the original accuracy of the same.
