High-Precision Servo-Driven Stamping Solution: Professional Evaluation, Data & Buying Guide

I. Core Technology & Professional Evaluation (with Test Data)

Q1: What is the structural feature of Qiaosen ST Servo Series? How does it ensure high precision?

• Fuselage deflection (full load 110%): ≤ 0.025 mm/m (better than mechanical STN series ≤0.03 mm/m)
• Slider parallelism: ≤ 0.015 mm / 300 mm
• Repeat positioning accuracy: ≤ ±0.003 mm
• Crankshaft: 42CrMo forged alloy (1.3× stronger than 45# steel)
• Precision standard: JIS Class 1 (ISO 9001 & CE certified)

Q2: What are the advantages of servo drive? Any measured efficiency & energy data?

• No-load SPM: 20–120 (adjustable)
• Full-load continuous SPM: 55–65 (stable)
• Energy consumption: 0.72 kWh/h (vs mechanical 0.85 kWh/h → 15% energy saving)
• Silent performance: ≤ 72 dB (full load)
• 2000-hour continuous test: No failure, bottom dead center drift ≤ ±0.002 mm

Q3: How about the control system & operation convenience?

• 9 standard processing curves (blanking, bending, deep draw, pendulum, etc.)
• Arbitrary stroke setting: 10–250 mm (no mechanical adjustment)
• Electronic cam + soft limit: avoid overload collision
• Real-time monitoring: load, temperature, stroke count, error log
• Interface for auto feeder / robot / safety light curtain
