electrolytic grinding and polishing of hand model-pg电子平台

electrolyte plays an important role in hand plate electrolytic grinding and polishing. an important factor that affects the polishing result and quality is the electrode gap, that is, the height of the conductive matrix protruding from the abrasive particles. keyo mould handplate

the power supply for hand electrolytic grinding and polishing can be full-wave rectified, and the rectangular wave with equal pulse can be output after voltage regulation and chopper of scr. the maximum output current is 10a, and the voltage is 0 ~ 24v. normal dc power supply can also be used.

electrolyte plays an important role in hand plate electrolytic grinding and polishing. the selected electrolyte should be free from persecution, with high processing productivity, but the requirement of stray corruption is small, and the common single-component electrolytes such as sodium chloride, sodium nitrate and salt water can hardly meet the above requirements. the electrolyte is dissolved with 150g sodium nitrate and 50g sodium chloride per liter of water. this electrolyte is non-toxic, but be careful not to make it thick with organic matter or subjected to violent vibration.

an important factor that affects the polishing result and quality is the electrode gap, that is, the height of the conductive matrix protruding from the abrasive particles. if the electrode gap is too large, the current density is small and the result is low. if the gap is too small, the electrolytic product is difficult to eliminate, easy to produce current short circuit, the roughness of the workpiece appearance after polishing is uneven. normal electrode clearance can be 0.1 ~ 0.25mm.
