Components : Abrasive dosing head

The new type of abrasive dosing head saves valuable time at the maintenance. An optimized constructive solution simplifies both the general handling as well as the maintenance. Juergen Moser, managing director of STM Waterjet Solutions, explains:

The abrasive dosing head in its previous design worked good, although cleaning and maintenance e.g. after a water splash back were difficult. A water splash back can occur when the jet focus sets on the Workpiece. During a water splash back water runs up the abrasive hose into the funnel towards the glass case. The new constructive solution of the abrasive dosing head, a compact unit, makes the maintenance much easier for the customers. To get to the parts to maintain no covers have to be taken off any more.

The funnel under the dosing unit is composed of a simple sliding mechanism that can be taken out simply. Stoppage in the abrasive dosing head can be removed quickly and easily. Also, the venting of the glass case of the abrasive dosing head has been completely redesigned. The upper cap presents a specially developed venting profile in order to avoid building up pressure in the inside of the glass case
