Core end face cutting mill is suitable for cutting all kinds of metal, non-metal materials (rock sample, coal sample) sample, in order to observe the material metallographic, lithographic structure. The machine is equipped with a cooling device, and the cooling liquid can take away the heat generated during cutting to avoid the sample overheating and burning the sample tissue. This machine is easy to use, safe and reliable. It is widely used in the preparation of experimental rock samples in the laboratories of universities and scientific research institutes. It is one of the necessary equipment for making samples in laboratories of scientific research institutions and universities. The machine is by the motor as a power output, cutting blade directly installed on the output shaft of the motor, effectively ensure the coaxiality of the blade, limit
