Shearing machine qualityAuthentication case

An equipment factory purchased a hydraulic shearing machine from a machinery factory to speed up efficiency for later business expansion. But what I didn't expect was that on the day of delivery, during debugging, it was discovered that the manual adjustment gap could not be turned, and there were abnormal pauses during the power-on test run. So the equipment factory refused to sign for the goods and failed to pay the balance, so the machinery factory took the equipment factory to court and required the other party to pay off the money in accordance with the contract.
The equipment factory, citing serious quality problems with the shearing machine, requested an appraisal agency to intervene to confirm the quality of the shearing machine. Therefore, the expert team went to the site to conduct survey and measurement. After identification, it was found that the workbench panel and scale of the shearing machine were obviously uneven, and the thickness obviously did not comply with the provisions of the treaty. The side plate of the fuel tank was welded and did not comply with the provisions of the relevant treaty. In addition, the friend phenomenon occurred at the oil port joint of the pressure cylinder during the material pressing process, indicating that there are serious quality problems in the hydraulic pipeline and oil port seal. In addition, the tool holder is defective and cannot be reset immediately.
Generally speaking, the shearing machine has serious quality problems, cannot work normally, and does not comply with the provisions of the contract between the parties.
