| titleOfInvention | Device for hydraulic grinding of holes of printed circuit boards |
| abstract | The invention relates to the manufacture of printed circuit boards and can be used for waterjet stripping of their holes. The purpose of the invention, improving operational capabilities, is achieved by reducing the emission of abrasive into the atmosphere, which reduces the consumption of abrasive and improves working conditions. The device is equipped with an abrasive collection chamber (CC) 8 connected by drainage channels (OK) 27 and 28 to the processing chamber 1. When air is released from the tank 4 or 5 through the valve 22 or 23, part of the abrasive with water and air enters the COP. where the abrasive and water are separated by a filter 24 and are discharged through the DC into the treatment chamber, between which and the COP in the DC, non-return valves 29 and 30 are installed. 3 ill. |
