There is growing demand for machining the ceramic based superconducting material. Good quality machining of this material is required for several purposes. The brittleness and hardness of the material and the need to eliminate the dust make its cutting and drilling more complicated. Naturally, the phase composition of the material must remain unchanged. The process described in this paper ensures the above-mentioned criteria. We have worked out four methods. These technologies have been tested and applied. The advantage of the process is that it is fast and ensures good quality. The complete machining of a work piece took about 15-20 min. Selecting the applied technology requires compromises. If the material needs no soldering, and we want to use a 100% environmentally friendly method, it is advisable to choose rinsing and cooling with liquid nitrogen. The greatest advantage of it would be the working of MgB2, because working must be carried out without using water or oil derivatives. The technology of working YBCO is as follows: The superconductor is impregnated after it is produced. The material is worn with diamond dust and rinsed with water or paraffin. After working, YBCO superconductor is impregnated with hard paraffin again. The analyzed samples did not show phase changing. This is a low-cost and 100% environmentally friendly method if liquid nitrogen is used. Technology using material impregnated after production and minimal water rinsing can be preferable as superconductor dust can be recycled at 100 deg C. However, using liquid nitrogen for drilling, we can machine the material in the state of superconductor. Moreover, the dry superconductor dust is available in 10 min after working. This is why we call it an environmentally friendly method.
