High speed revolution of diamond rollers carries out rigid milling and scratching processing to surface processing to surface of ceramic tilesto achieve flat surface and unified thickness, hence to improve polishing efficiency and quality, reducing production cost of granite porcelain tiles.★ Good rigidity of principal axis, great cutting force and high efficiency.★ The roller holder and supporting parts adopt new generation of integral casting structure in order to ensure the machine to operate more stably. And it is attached with horizontal Micro-adjusting device features good vibration damping property and less processing breakage
