<p>The press has an electric reference value transmitter, which influences the hydraulic unit of force, via an amplifier, and a regulating member. To the above gp. may be added an actual value transmitter, and a correcting member, to form a circuit, which is automatically error-compensating through an electric return. The press is used in the following industrial branches:- ceramics, powder metallurgy, grinding wheels, graphite processing, and similar, to press powderised materials into formed parts. It combines the advantages of hydraulic and mechanical presses.</p> |
