Mechanical press PMX-L2 series

formingstampingfor sheet metal

Description
The PMX-L2 Series comprises high-precision, high-rigidity mechanical 2-point straight-side presses with link-motion, designed for progressive-die stamping. The tie-rod frame with wide-spaced connections and long slide guides combined with forged eccentric shafts and minimized bearing clearances reduces vibration and noise, maintains long-term accuracy and supports heavy progressive dies. The center-drive link-motion limits torsional wind-up of eccentric shafts and increases dwell time in the forming zone to improve material flow and part quality.

Key features

• Mechanical 2-point straight-side construction with link-motion for progressive-die operations
• Highly rigid tie-rod frame with wide spacing and long slide guides for low deflection
• Forged eccentric shafts with center drive to limit torsional wind-up
• Bearings with minimal clearances to reduce noise and preserve accuracy
• Dynamic balancing of slide and upper die to support high-speed operation
• Capacity variants to withstand off-center loads and heavy stamping
