Loading machines - Import export

The machine accurately doses gold and silver grains for the prodcution of bullions and cast bars. The Preci-dos is completely automatic, with dosing cells and grains transfers completely controlled by PLC. It has a number of steps to achieve accurate control on final weight. The grains container in the machine are loaded by gravity into the pre-dosing scale, to approach the final desired weight. After the pre-dosing step, a second phase starts to reach the final desired weight by adding a controlled quantity of gold or silver wire or powder (depending on customer specification) and the discharge the correct quantity of material into a container. To maintain accuracy and productivity, the machine is capable of self-learning, based on the continuous use. In particular the machine can statistically anticipate the average drop time of a single grain, to avoid overshoot.

The boring machine, model TSB3, is designed for machining of hydraulic cylinders internal holes, with diameters from 20 up to 300 mm. The machine can be adjusted manually or automatically and it has got an electrowelded , normalized carpentry base . It is simple to use and easy to programm; it works with blocked piece and rotating tools on two opposing units. Toolholder devices, permit the machining of more diameters in the same workpiece, chamfing and internal and external threading. The machine can be adjusted manually or automatically and it has got an electrowelded , normalized carpentry base . The boring machine TSB3 is equipped with a bench with adjustable supports depending on workpieces size. The hydraulic self – centering vise ensures the perfect orthogonality of machining; the load and unload are made manually , by the operator. The machine is controlled by a CN Siemens SINUMERIK 840 D SL.
