The Q-80Z cutting machine can not only cut circular workpieces with a diameter of less than 80mm, but also rectangular specimens with a height of 80mm and a depth of less than 200mm. This machine cools the sample through a cooling system to prevent overheating and tissue damage during the cutting process. This machine can also set the cutting speed for cutting different samples, thereby improving the quality of cutting samples. This machine is divided into automatic cutting and dynamic cutting, with a large volume cutting chamber that is more convenient for cutters to use. It is one of the essential sample preparation equipment for metallographic testing in universities, factories, and enterprises. Technical indicators a) Power supply: three-phase four wire (380v, 50Hz) b) Spindle speed: 2100 rpm c) Grinding wheel specification: 350mm × 2.5mm × 32mm d) Maximum cutting capacity: φ 100mm Note: The cutting ability mentioned here refers to the designed cutting ability of the new cutting wheel, and the actual cutting ability depends on the sample material, grinding wheel, and clamping technology. e) Maximum cutting volume: 100mm × 200mm f) Electric motor: YS90L2-2 3KW g) Cutting table size: 310 × 280mm h) Boundary dimension: 930 × nine hundred and ninety × 1230mm
