STD Series Closed Single-Point Single-Crank Ultra-Heavy Precision Punch Press

Q1 Exclusive Core Advantages & Lab Test Data

1. One-piece ultra-heavy closed H-frame (full steel welded)

   
   

   High-temperature stress relieved, full-load deflection ≤ 0.008mm. Higher rigidity than STV; minimal vibration under 24/7 heavy stamping.
   
   
2. High-grade crankshaft & transmission

   
   

   Forged 42CrMo alloy steel crankshaft (HRC 54–58). Strength 1.4× higher than 45# steel, fatigue life +230%. All gears precision ground; low noise, long service life.
   
   
3. Precision & guide system

   
   

   4-corner 8-sided enclosed guide, high-frequency hardened (≥HRC 50) and precision ground.
   
   
   • Slider parallelism: ±0.008mm
