Cutting method for refractory metal and alloy thereof

The invention discloses a cutting method for refractory metal and alloy thereof. The cutting method specifically comprises the following steps that (1), a workpiece is fixed through high-strength resin; (2), a resin grooved wheel is grooved; (3), a cutting line is wound; (4), tension is applied to the two ends of the grooved wheel wound with the cutting line; (5), the position of a bearing table is adjusted; (6), the ascending speed of the bearing table and the reciprocating motion running speed of the cutting line are set; and (7) cutting and soaking with an organic solvent are carried out to separate the resin bonded with the material from the material, so that the required sheet is obtained. Refractory metal and alloy are cut through reciprocating motion of a high-speed diamond cutting line, and the problems that in the cutting process, the workpiece moves, wires are broken, the product size precision is not controlled and the production efficiency is low due to the fact that the workpiece cannot be effect
