There are several types of granite engraving machines, including: CNC machines, laser engravers, and hand-held engraving tools. CNC machines are the most commonly used and can create a wide range of designs and patterns.
A granite engraving sand blasting machine is a specialized tool that uses a combination of sand blasting and engraving techniques to create intricate designs and patterns on granite surfaces. The machine uses compressed air to propel abrasive particles at high speeds onto the granite surface, while also using a diamond-tipped or other hard-material bit to carve and shape the stone.
