All the statutory holidays of the year, I always feel that a holiday belonging to spring is worth looking forward to: the sky is bright, everything is thriving, and both internal life and external world have become lively and lovely, including your laboratory.


So in the good things recommended by the editor of Chain Energy in March, they are also full of a relaxed and lively work atmosphere: before cutting the samples, the grinding wheel cutting pieces need to be stored first; Various metallographic grinding and polishing consumables such as metallographic sandpaper and metallographic polishing cloth may have discounts in large quantities; Some people have recently purchased a metallographic polishing machine, which has led to a sharp increase in work happiness. Don't say much, follow the editor and look down:

     Original imported QMAXIS (pulse) grinding wheel cutting blade from the United States: a cutting blade specifically designed for metallographic grinding wheel cutting machines. It is suitable for metallographic cutting of most materials such as various steels, superalloys, Ferrous and nonferrous metals. Grinding wheel metallographic cutting blades belong to wear type cutting blades, which are environmentally friendly resin bonded, economical rubber bonded, and glass fiber reinforced cutting blades that can achieve dry cutting. The cutting temperature is low, the plastic deformation is small, the cutting accuracy is high, the cutting speed is fast, and the service life is long.

     Original imported QMAXIS (Kemai) silicon carbide metallographic sandpaper from the United States: paper based with strong toughness, good water resistance, uniform and dense distribution of silicon carbide particles, sharp, and high removal rate. By grinding the metallographic sample with it, the surface scratches are small, which is beneficial for subsequent polishing processes and can effectively shorten the sample preparation time.


Speaking of many old customers of Chain Nengjia, various metallographic sample making consumables used in the laboratory, from grinding wheel cutting blades used for cutting to metallographic sandpaper used for grinding and polishing, All using American QMAXIS! Big brand, with guaranteed quality, it is also very worry free and reassuring to use.

    The original imported QATM double disc automatic metallographic polishing machine Qpol 250 A2-ECO from Germany has a working disc diameter of 200-250 mm. The new work disk assembly system, new control software, and all preparation methods can be edited and stored, and protected through user account management. Pressure, speed, and rotation direction can be adjusted. The TOPAS ECO dosing system can be selected for use, providing more flexible operation and convenience for sample preparation. The shockproof plastic inner cover adopts powder coated aluminum outer cover and high standard technology of the equipment, giving it the characteristics of quiet and smooth operation and better preparation results. Simple operation, easy installation and maintenance, making it an ideal automatic grinding and polishing equipment for metallographic laboratories.
