1. Professional Product Evaluation with Laboratory Test Data
All data in this section comes from 72-hour continuous stamping test, material hardness test, precision attenuation test, energy consumption comparison test and eccentric load resistance limit test completed in Qiaosen Machinery laboratory.
Q1: What are the actual measured data of frame and core component materials of Qiaosen precision punch presses?
Laboratory Test Data
- Machine frame: All models adopt integral welded frame made of high-strength thick steel plate with high-temperature stress relief treatment. The measured deformation rate of the frame is ≤0.02mm, far lower than the industry average standard of 0.08mm.
- Crankshaft: Made of 42CrMo high-strength alloy steel. The measured Rockwell hardness reaches HRC 52~56. Compared with ordinary 45# steel crankshafts on the market, structural strength is improved by 1.3 times, crankshaft failure risk reduced by 92%, and fatigue life increased by 2.1 times.
- Transmission bushing: Customized 10-1 phosphor bronze material. Its wear resistance is 1.5 times higher than ordinary BC6 brass. The wear value after 300,000 consecutive stamping cycles is only 0.008mm.
- Guide rail system: Closed models adopt eight-sided enclosed guide rails on four corners with high-frequency quenching treatment (hardness ≥ HRC 48). Tested by three-coordinate measuring instrument, the flatness, parallelism and verticality of guide rails reach 0.01mm/㎡, with extremely low long-term wear and excellent precision retention.
Q2: What are the measured core data of stamping precision, stroke adjustment and operating speed?
All Qiaosen machines are delivered with official JIS Grade 1 precision inspection reports. Special precision test data is as follows:
- Slide parallel precision: ±0.015mm; Slide vertical precision: ±0.02mm.
- Mold adjustment precision: 0.1mm fine adjustment without clearance, suitable for precision stamping of thin hardware sheets and electronic terminals.
- Adjustable stamping stroke: 80mm for open-type machines; 50~120mm adjustable stroke for semi-closed and closed models.
- Actual operating speed: Standard ST series machines support maximum 150 strokes per minute; High-speed STS models reach up to 300 strokes per minute with stable operation without shaking or offset.
Q3: What are the limit test data of safety protection and overload protection performance?
Laboratory Extreme Working Condition Test Data
- Equipped with dual solenoid valves, pneumatic brake system, infrared photoelectric protection, anti-secondary stamping mechanism and mechanical overload protection system.
- Overload resistance test: The machine shuts down within 0.03s under 120% overrated load impact, with no slide falling or frame damage, fully protecting molds and operators.
- Brake response time: Clutch-brake linkage response duration ≤0.05s, leading-level response speed in the industry to eliminate secondary stamping risks.
Q4: What is the comparative energy-saving data of power consumption and material utilization?
We conducted a parallel comparison test among Qiaosen ST-80 punch press, ordinary 80T mechanical punch press and mainstream branded 80T precision punch under identical working conditions: 12 hours daily operation, stamping thin stainless steel sheets.

Q5: What is the reliability data from 72-hour non-stop durability test?
72-hour continuous stamping durability test (ST-80 model, 0.3mm stainless steel punching)
- Total stamping cycles: 648,000 times
- Unplanned downtime during test: 0 time
- Dimensional deviation fluctuation: ≤0.02mm throughout the whole test without precision attenuation
- Mold wear rate: 40% lower than ordinary punch presses, effectively extending mold service life.
