The production of products generally through stamping, hydraulic, die casting, polishing, plating process.
Stamping: the engraved mold is installed on the machine, and the product pattern is transferred to the metal material needed, and then the blanking mold is made, and the product is rushed down with a punch press according to the product shape.
Hydraulic: with a good blanking die, the first product according to the shape of the punch down, in adjusting the mold, the product down on the machine to suppress the pattern.
Die casting: die casting is a casting method that pours molten alloy liquid into the pressure chamber, fills the cavity of the steel mold at high speed, and makes the alloy liquid solidify outside the pressure to form the casting.
Polishing: remove the burr on the surface and around the finished product to improve the finish of the product.
Plating: in the electroplating tank, nickel and cobalt bonding metals are deposited continuously on the steel body of the drill bit to form a fetal layer, and at the same time, diamond particles are deposited layer by layer on the plated surface of the drill bit, and the deposited metal fetal diamonds are evenly buried in it to form a working layer. The surface of the product forms an oxidation resistance.
