Design and R&D
The overall design of the universal testing machine includes systematic designs such as the mechanical framework, sensor selection, control system architecture, electrical system, software functions, and the overall appearance of the machine.
Host:
The core components of the mainframe, such as the force-bearing frame and the tooling fixtures, are precisely processed through procedures like machining centers, milling, planing, and grinding. Special parts undergo quenching and tempering treatment to ensure that the structural performance of each mainframe meets the design requirements.
Component Heat Treatment
Sheet Metal Processing:
Sheet metal processing: The sheet metal parts for the testing machine are processed through laser cutting, bending, stamping, welding, grinding, and powder coating procedures.
Quality inspection of processed parts:
The quality of each component directly affects the performance of the entire machine. Before use, each component undergoes a series of quality inspection procedures. Usually, its size, tolerance, hardness, surface treatment, etc. are inspected.
Workshop assembly:
The mainframe components, drive motor, transmission mechanism, sensors, tooling fixtures, sheet metal, etc. are strictly assembled in accordance with the company's assembly procedures, and the corresponding data are archived for easy future reference.
Debugging Phase:
Conduct various standard tests, including load accuracy, displacement accuracy, force stability, control precision, and other related calibrations.
Machine inspection and file archiving:
Overall equipment inspection: Cleanliness inspection, impact inspection, rust prevention inspection, safety label inspection, completeness of configuration, etc.
File archiving: After the overall equipment inspection is completed, record the equipment number, configuration information of tooling and fixtures, sensor configuration information, equipment parameter settings information, etc. Both paper and electronic versions are archived for easy future reference.
