Pressa meccanica PMX-S4 series

Description
The PMX-S4 Series is composed by high-precision, high-rigidity, straight side 4-point presses for progressive die applications. The highly rigid tie-rod frame coupled with bearings designed with minimal overall bearing clearances keep breakthrough to a minimum, which reduces noise, enables high long-term accuracy and extends die life. The PMX-S4 presses are manufactured with the slide suspension point centers positioned in very close proximity to the tie rod centers; the optimal structure for multi process forming, that enable widely-spaced left and right suspension points and heavy-duty eccentric loading capabilities. Moreover, the built-in dynamic counterbalances reduce vibration and enable stable high-speed production.

Key features

• Manufactured with forged eccentric shafts on a very low deflection tie rod frame with dynamic balancing of slide and upper die
• Built-in dynamic counterbalances reduce vibration and enable stable high-speed production
• The wide spacing between the points enables the PMX-S4 presses to effectively withstand off-center loads
• The highly rigid frame can withstand the progressive stamping of thick sheet metal
• The symmetrical front-to-back and left-to-right frame maintains high dynamic accuracy
