Sectored Calibration Wheel is a high-performance diamond tool used for precise thickness calibration and surface leveling of granite, marble, and other natural stone slabs. It is manufactured with premium quality diamond segments arranged in a sectored design, which allows efficient material removal, better cooling, and improved cutting performance.The sectored structure helps in reducing vibration, minimizing load on the machine, and ensuring smooth and uniform slab thickness. These wheels are widely used in automatic polishing lines and calibration machines as a preparatory step before polishing, ensuring superior surface quality and consistent results.
