==Function-Principles of mechanical presses in the field of Technical Ceramics== The function principles of the mechanic press machines differ in how to ensure the upper punch–main movement by cams, spindles-and friction drives, eccentric, knuckle-joints or by the round table principle, independent if the die-or lower punch movement is realized by cams- or eccentric systems or other mechanically or hydraulically combined systems. The executions of auxiliary movements are also not decisive for a term-classification. These auxiliary movements can also base on pneumatic and hydraulic principles. In comparison to hydraulic press machines the maximum compaction forces of mechanical powder presses are limited and are placed in the range For the requirements of wet-and dry pressing techniques in the field of Technical Ceramics cams-, eccentric-, knuckle joint- as well as round table presses have proved and tested, whereas cam-presses especially used for wet-press-techniques of pourable materials. The range of compaction force of mechanical presses for products of the Technical Ceramics is < 2500 kN, what is caused from the less density of the ceramic materials. Normally the upper punch-, lower punch- and die systems of mechanical presses don’t work on base of multi-subdivided punches. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mechanical powder press」の詳細全文を読む スポンサード リンク
