LZQ-450 this machine is a metallographic sample cutting machine automatically controlled by PLC. It can automatically and accurately control the X, y and Z directions. Intelligent cutting can change the feed amount according to the material hardness to achieve the fastest cutting effect. The cutting speed is controlled by frequency conversion. It has very high reliability and control ability; I. electronic hand wheel, automatic and random conversion; II. Touch screen displays various cutting data; III. accurate positioning; IV. swing cutting, continuous cutting, reciprocating cutting, variable speed cutting and four functional cutting methods. During cutting, the cutting speed can be changed according to the hardness of the material to achieve the purpose of rapid cutting. The cutting speed of solid steel cylinder can reach 15mm per minute. In order to facilitate the cleaning of cutting chamber and the safety of spindle motor, we adopt mechanical and electrical separation; The safety protective cover of the cutting room has a large observation window, which makes it easy for users to observe the whole process of sample cutting; LED lights are installed in the cutting room to effectively illuminate the area used by the whole cutting room; The ventilation fan in the cutting room can ensure the efficient flow and discharge of various steam and smoke generated during cutting, increasing the brightness and clarity in the working room; The design is more humanized and uses the principle of ergonomics Features: low noise, easy operation, beautiful appearance and safe use It is one of the necessary equipment for laboratory sample preparation.
