Diamond inlaid composite plating

Tools (such as drills, reamers, abrasive, roller, etc.) of diamond, cubic boron nitride and other superhard materials have been prepared to produce oil, and coal industry exploration and machinery, instruments, electronics and other minerals in the A large number of applications have been obtained in equipment processing. Preparing diamond tools are mainly two kinds of powder metallurgy and composite plating. Compared with the powder metallurgy method, the composite plating method has a simple equipment, can reduce the loss of the mold, does not cause the diamond to be subjected to heat loss, and is easy to repair, and thus has a place in the manufacture of the diamond tool. Depending on the number of layers of diamond particles embedded in the surface of the diamond tool, the manufacturing method can be divided into two types: the table setting method and the gestation method.
The process of the impregnation method is generally as follows: pretreatment - plating of diamond-free matrix metal Ni or Ni-Co) - sand plating - re-plating 3 ~ 5 Î¼m bright nickel - surface finishing.
The specification of electroplated nickel-based diamond inlay plating is as follows: nickel sulfate 220-240g/L, cobalt sulfate 15-30g/L, boric acid 25-35g/L, sodium chloride 10-20g/L, 1,4-butyne II Alcohol 0.6-0.8 g/L, saccharin 0.8-1.0 g/L, sodium lauryl sulfate 0.08-0.1 g/L, diamond (5-7 Î¼m) 5-10 g/L, temperature 45-50 Â° C, pH 4.1 to 4.5, current density 2A/dm ² , strong agitation of air.

STSQ6A 6 Ton Crane features

1. The optimizing layout of the machine makes the stress of the main bearing carriers more reasonable, and the lifting performance is higher than the products with the same tonnage.
2. Optimize the stress design. Adopt the box-type outriggers which have larger span, stronger rigidity, and better stability.

3. Full hydraulic pressure drive, electrical and oil dual-purpose, safe and reliable work, high efficiency, low labor intensity;
4. Every hydraulic system equipped with balancing valve and hydraulic lock, safe and reliable performance
5. Crane jib and important components are made of high strength steel plate to reduce weight of crane and improve crane performance;
