Infrared bridge cutting machine quality appraisal

The

infrared bridge cutting machine uses high-precision infrared positioning and dynamic cutting synergy as its core principles. By optimizing the laser centering accuracy, cutting head verticality and servo system response speed, it can achieve precise cutting of stone, ceramic tiles and composite materials, synergy between cutting quality and processing efficiency. It is widely used in fields such as architectural decoration, stone processing and industrial material segmentation. In the processing of stone curtain wall, it is used for complex contour cutting of special-shaped plates; in the field of ceramic tile production, it meets the needs of rapid slicing of large slates; in the composite materials industry, it ensures the low-loss processing of carbon fiber boards. Compared with traditional bridge cutting machines, infrared bridge cutting machines have the characteristics of non-contact positioning (zero material scratches), intelligent path planning and adaptive compensation (temperature/humidity real-time calibration), and are the core equipment of high-precision cutting technology.

Zhongke Testing is a product quality appraisal service organization registered with the court. It can provide quality appraisal services for infrared bridge cutting machines. It has a professional appraisal team and advanced instruments and equipment to provide fair and accurate appraisal results for the quality appraisal of infrared bridge cutting machines.

As the processing accuracy of decorative materials has been upgraded, related quality dispute cases have increased significantly. The judicial dispute focuses on:

1, performance index dispute: cutting size is out of tolerance, infrared positioning repeatability is insufficient;

2, material defects: insufficient guide rail hardness, cutting head bearing axial play;

3, process problems: servo motor overshoot, cooling system failure leading to thermal deformation;

4, contract performance dispute: core modules (such as high-power lasers, five-axis linkage systems) are inconsistent with the technical agreement.

0 Such cases need to pass cutting accuracy verification, material failure analysis and dynamic performance testing to clarify the quality responsibility.

The litigation quality appraisal of

infrared bridge cutting machine usually adopts the following technical methods:

1. Appearance inspection: Visually inspect the appearance, structure, and parts of the equipment to determine whether there are obvious defects or abnormalities.

2. Performance test: Test the function and performance indicators of the equipment in accordance with national standards or industry standards, and evaluate its cutting accuracy, cutting speed, stability and other indicators.

3. Safety testing: Test the electrical insulation, mechanical safety protection, stress testing, etc. of the equipment to ensure that it meets relevant safety standards.

4. Material analysis: Conduct material analysis on key components of the equipment to determine whether the material quality meets the design requirements.

05. Process evaluation: Analyze the processing technology of the equipment to determine whether the process is standardized and whether there are potential quality hazards.

A stone factory of the applicant signed a "Five-axis Infrared Bridge Cutting Machine Purchase Contract" with an equipment manufacturer of the respondent, and it was agreed that the cutting size tolerance is ±0.1mm. After the curtain wall panels were put into production, the seams were out of tolerance by 0.5mm. The manufacturer argued that this was caused by uneven stone textures.

Identification analysis results:

The quality analysis expert group discussed and comprehensively analyzed the relevant information of the "infrared bridge cutting machine", contract technical agreement, on-site investigation case materials and other data, and made the following quality analysis opinions:

The X-axis guide rail hardness of the infrared bridge cutting machine involved in the case is only HV 580 (protocol ≥ 700), resulting in repeated positioning accuracy of ±0.15mm; the infrared calibration module was interfered by ambient light, and the positioning offset was 0.12mm; the acceleration and deceleration curve of the servo system was improperly set, with an overshoot of 0.08mm.

The appraisal conclusion determined that defects in the mechanical structure and control system were the main causes of the out-of-tolerance.
