In marble medallion industry, when the tilting angle of the cutting head is the biggest 4°, the kerfs section will change a lot. By the compensation of angle during cutting, the cutting kerf will be a reversed taper. When two pieces of cutting parts are matching together, the top surfaces have no aperture but the one of bottom surfaces is big. In this way the twice polishing producer by manual will be saved, which reduces the processing cost and enhances the working efficiency. With this improved four-axis dynamic cutting head design, it is no longer a difficult technique in marble matching. It made traditionally complex marble matching an easy job.The quality of marble pattern has had a great increase and the making of pattern has no longer been a very difficult technology at the same time.
