QG-4A multi energy cutting machine Main features: This machine is suitable for cutting irregular general metallographic sample materials such as cylinder and polygon, so as to observe the metallographic and petrographic structure of the materials. Double enclosure fully enclosed structure and door type safety switch are adopted. It can ensure that the sample can be cut in an absolutely safe state. This machine is equipped with strong cooling system. Using the configured coolant can take away the heat generated during cutting and avoid the sample overheating and burning the sample tissue. The machine is easy to use, safe and reliable. It is one of the necessary equipment for making samples in the laboratory of factory scientific research units. Main technical specifications: Maximum cutting diameter: φ 65mm; Spindle speed: 2800r / min: Cutting blade specification: φ 250*2* φ 32mm; Input voltage: three-phase 380V50Hz; Input power: 1.5kw Overall dimension: 990 * 670 * 1320mm; Net weight: 230kg
