Sample size: 100mm × 150 mm 3.The abrasive uses F80 corundum abrasive 4, storage hopper volume is greater than 5L 5, test time can be preset, digital display 6. Pressure weight 1: the mass is 2.5㎏, applicable to GB / T3810.6-2016 Pressure weight 2: mass 14㎏, applicable to GB / T12988-2009
3. Working principle and result evaluation: The instrument consists of a power transmission part, a sample holder part, an abrasive storage supply part and an electrical control part.The grinding wheel rotates at a constant speed, and the sample contacts the friction steel wheel with a certain pressure by applying a pressure weight. The abrasive uniformly enters the grinding zone at a specified flow rate (100g / 100r / ± 10g / 100r), and the surface of the sample is made by the abrasive Grinding pits are created.By measuring the chord length of the grinding pit on the surface of the sample (accurate to 0.5㎜), the grinding pit volume is calculated to represent the degree of wear of the sample.Each sample was evaluated by the average abrasion volume at two locations.
