Although the destruction of hard rock is considered to be the main application for AWJ in mining, this technology can also be used (as mentioned above) to cut nonrock materials. Therefore, there is a need for a method to predict the efficiency of cutting with AWJs that is highly accurate irrespective of material.
Mar 13, 2012· (1) Drill AdaptabilityThe type of rock drill used in mining drilling is generally determined by the hole diameter required and the mechanical properties, principally hardness, of the top hammer is commonly employed for drilling of holes less than 125 mm in diameter in all but the hardest rock, although a rotary cutting method may instead ...
Once the slabs are cut into the right size pieces using on our SawJet saw, we use our CNC (computer numeric control) stone routing machines to cut and polish custom edges on the pieces of granite countertop and cutout precise shapes for any sinks or cooktops. Final Touches by Skilled Craftsmen
Thermal spalling drills such as jetpiercing and forcedflame drills heat rocks to 370 to 540°C (700 to 1000°F) to create thermal stresses that spall the rock ().These devices have limited application because most rocks will not thermally spall (Maurer, 1968, 1980). Melting and vaporization drills utilize hightemperature devices such as lasers or electron beams to melt and vaporize rock ().
