Quality appraisal of CNC bending machine

CNC bending machine is a modern metal processing equipment controlled by a computer program. Its main function is to bend metal sheets. It controls the operating system by manipulating programming software to accurately control the motion trajectory and speed of the machine tool cylinder, thereby achieving high-precision, high-efficiency, and highly automated production.
CNC bending machine uses the equipped mold (general or special mold) to bend cold metal plates into workpieces of various geometric cross-section shapes. It is a plate forming machine designed for cold-rolled sheet metal processing. It is widely used in plate bending processing in automobiles, aircraft manufacturing, light industry, shipbuilding, containers, elevators, railway vehicles and other industries.
In the case of CNC bending machine quality appraisal, Zhongke Testing can provide CNC bending machine quality appraisal services.

1, mechanical part inspection
The mechanical part of the CNC bending machine is an important part that supports the entire equipment. Therefore, when inspecting the quality of a CNC bending machine, its mechanical parts must be carefully inspected to ensure its tight structure and easy operation.
2. Inspection of the mechanical part
The mechanical part of the CNC bending machine is an important part that supports the entire equipment. Therefore, when inspecting the quality of a CNC bending machine, its mechanical parts must be carefully inspected to ensure its tight structure and easy operation.
3, safety assurance inspection
A good CNC bending machine must have high standards of safety assurance, including the safety of testing equipment, the rationality of installation design, and the integrity of protective measures. Safety guarantee is an important guarantee for the quality of industrial equipment, and it needs to be focused on when conducting quality inspection of CNC bending machines.

quality product dispute situation:
According to the situation reported by the client and the information provided, the client signed a "Purchase and Sales Contract" with an electromechanical equipment company (hereinafter referred to as the supplier) to purchase a "CNC bending machine" involved. The client discovered during the production process that during the performance of the contract, after installation and debugging by the supplier's technical staff, the "CNC bending machine" failed to meet the corresponding technical requirements (that is, the maximum working output pressure did not reach the nominal pressure).
In order to further clarify the reasons why the equipment cannot produce normally, the client hopes to investigate whether there are quality problems in the "CNC bending machine" involved.
quality analysis results: The
quality analysis expert group discussed and comprehensively quality-technically analyzed the relevant information and on-site investigation and inspection of the "CNC bending machine" involved, and made the following suggestions and conclusions:
After the product provided by the applicant increases the set pressure of the electromagnetic relief valve, the nominal pressure of the CNC bending machine (i.e., the maximum working output pressure) can meet the technical requirements agreed upon in the contract signed by both parties.
