I. Introduction: the core position of CNC Press Brake in the modern manufacturing industry
CNC Press Brake as the core equipment for sheet metal processing, its performance directly affects production efficiency, product quality and cost control. With the manufacturing industry to high-precision, intelligent direction, CNC Press Brake technology iteration and brand competition is also increasingly fierce. In this paper, we will analyze the technical parameters, a comprehensive comparison of brands, the development of three major dimensions of the purchase strategy, and combined with actual cases, to provide readers with a set of scientific and practical guidelines for the purchase.
II, the core technical parameters of CNC Press Brake purchase analysis
1. Bending force and tonnage selection
CNC Press Brake tonnage (i.e., bending force) needs to be based on the thickness of the material, the material and the bending radius of the integrated determination. For example, the processing thickness of 2mm of 304 stainless steel, you need to choose at least 60 tons of CNC Press Brake. If the thickness of the material is more than 6mm, it is recommended that the tonnage to 100 tons or more, and give priority to the hydraulic or servo-driven system of high rigidity models.
2. Accuracy and Repeat Positioning Accuracy
High-precision CNC Press Brake can reach a repeat positioning accuracy of ± 0.01mm (such as Germany’s TruBend series), while the ordinary models are usually ± 0.05mm. For aerospace, medical equipment and other precision industries, you need to choose models equipped with a laser angle measurement system, real-time monitoring of the bending angle error.
3. Backstop system and mold compatibility
Backstop accuracy directly affects the consistency of workpiece dimensions. High-end models use 6-axis linkage servo backstop to support the positioning of complex workpieces. In addition, the efficiency of mold change should be concerned: the quick mold change system can shorten the downtime to less than 5 minutes, which is suitable for small batch production of multiple varieties.
4. Comparison of drive modes
– Hydraulic drive: low cost, suitable for conventional plate processing, but with high energy consumption (about 30% energy loss).
– Servo drive: more than 70% energy saving, better precision and response speed, suitable for high value-added products.
– Electro-hydraulic hybrid drive: combining the advantages of both, outstanding performance in thick plate processing (such as Tianshui Forging TSD series).

V. Option Strategy Development: The Complete Process from Demand to Landing
1. Demand List Construction
| Evaluation dimension | Key index | Data sources |
| Production capacity | Daily output (pieces) | Historical order analysis |
| Material type | Common plate thickness/material | Supply chain list |

| Scalability requirements | Production capacity growth forecast for the next three years | Corporate strategic planning |
2. Cost-Benefit Analysis Model
– Initial Investment: Equipment Price + Installation and Commissioning Costs (40%-60% of budget) – Operation cost: energy consumption (hydraulic machine about $25/hour vs. servo machine $12/hour) + maintenance cost (5%-8% per year)
– Payback period: formula: `(total equipment price – salvage value) / (yearly cost saving – yearly new cost)`
3. Supplier Evaluation System
– Technology Ability: the number of patents, the proportion of R & D investment (international brands usually > 8%)
– Service network: whether there is a direct service center within 200 kilometers
– Case validation: the requirement to provide detailed data on more than 3 successful cases in the same industry
