Granite plate surface treatment aparatus with surface measurement function

摘要

The present invention relates to a granite plate surface treatment apparatus having a surface measurement function, wherein a measuring laser is placed on both left and right sides of a typical granite plate surface treatment apparatus, where a polishing tool is located, so as to receive a returned laser beam. Moreover, a received signal finally receives processing thickness by comparing measured value through a measurement detecting unit, and grinding can be performed while the processing depth of the polishing tool is corrected by a control plate. Accordingly, unnecessary flatness inspection-measurement using an electronic level can be removed. In addition, a replacement period or damage in accordance with the degree of abrasion of the polishing tool can be estimated so that time for surface processing work can be significantly reduced. Furthermore, a granite plate having higher flatness in manual lapping and polishing works, performed after the surface processing work, can be provided.
