For the determination of Brinell hardness of ferrous, non-ferrous and bearing alloy materials Such as cemented carbide, carburized steel, hardened steel, surface hardened steel, hard cast steel, aluminum alloy, copper alloy, malleable casting, mild steel, quenched and tempered steel, annealed steel, bearing steel, etc.1. Measuring range: 5-650HBW 2. Test force: 1838.8, 2415.8, 7355.3, 9807, 2942N (187.5, 250, 700, 1000, 3000kgf) 3. The maximum allowable height of the sample: 230mm; 4. Distance from the center of the indenter to the machine wall: 130mm; 5. Hardness resolution: 0.1HBW; 6. Dimensions: 700*268*842mm; 7. Power supply: AC220V/50Hz 8. Weight: 210Kg.1. Equipped with high-performance stepper motor for automatic loading and unloading, the noise generated during the test is smaller; 2. Solid structure, good rigidity, accurate, reliable, durable, and high test efficiency; 3. Overload, over-position, automatic protection; automatic test process, no human operation error; 4. Automatically input the indentation diameter and directly display the hardness value, which can realize the conversion of any hardness scale and avoid the cumbersome look-up table; 5. Equipped with built-in micro-printer, and optional CCD image processing system; 6. Accuracy conforms to GB/T231.2, ISO6506-2 and American ASTM E10 standards.Large flat workbench, small flat workbench, V-shaped workbench: 1 each; Steel ball indenter: Φ2.5, Φ5, Φ10 each 1; Standard Brinell hardness block: 2
