The key problems of bead electroplating and hot - pressure sintering of diamond wire saw are solved

The electroplating of diamond rope saw beads is basically the same as that of general diamond electroplating products. What is slightly different is that the beads are small and how to improve work efficiency. Generally, the beaded matrix can be worn on a clamp, both ends are tightened with nuts, and the non-plated parts are insulated with plastic cloth. The size of the plating bath depends on how much of the substrate is worn in a row. If the bath allows, hundreds or more can be plated at a time. Additional sand, thickening is best in different plating bath. Sand to rotate the beads horizontally (clamp), while thickening can be rotated vertically, can be plated more.

Hot-pressed sintered diamond beads are mainly used for cutting granite and cement products. Beads are small in diameter, thin in diamond layer, and there are a lot of beads in a rope. Therefore, three key problems to be solved in manufacturing by hot pressing sintering method are as follows: first, the selection of binding agent. Cobalt - based binders (mostly pure cobalt) are widely used in foreign countries. Domestic USES the multielement alloy binding agent, the basic component is Fe, Co, Cu. Secondly, the thickness of diamond layer should be less than or equal to 1.5mm, which makes the structure and life of the mold difficult. The foreign solution is to form a ring blank by cold pressing (each bead is divided into two rings), then cover the matrix, put into the graphite mold, send the hot pressure. Thirdly, the production efficiency of mixture weighing, cold pressing and hot pressing.
