PURPOSE:To process material stones to give appearance of natural stones in a short time by blasting steel grit and balls with comparatively great diameter to each material stone together with high-pressure water. CONSTITUTION:Material stones for garden landscaping get rid of sharp angles and protrusions unsutable for the purpose and undergo inspection to know where they have texture, foreign matter, cracks or brittle parts to possibly cause defoliation. Steel grit and balls with a comparatively large dia. are blasted together with high-pressure water to these defective parts, followed by honing, to tear off all defoliable parts, cut away the foreign matters and bore the brittle parts in a comparatively short while. The resultant stones will be also provided with properly worn ridges. Consequently they will appear as natural stones weathered by water stream.
