Abrasive metering
The precise control of garnet feed into the water jet during high-speed cutting. Important for efficiency and results.
Physical-Chemical Mechanism of Action
Garnet stands out for its hard surface, which effectively abrades metals. The dosing determines how much garnet is mixed into the water jet to achieve optimal cutting performance.
Metallurgical Relevance & Welding Risks
Inaccurate dosing can lead to too much or too little abrasion. Too much garnet causes excessive temperature rise and can damage the workpiece, while too little does not cut sufficiently. This increases machining time and material costs.
Workshop Practice & Instructions
Use a garnet dosing machine with precise control. The optimal dosing varies by material, but generally it is 0.5 to 1 g per liter of water jet. Constantly monitor cutting performance and adjust the dosing accordingly.
