CNC machining machine tool quality appraisal

CNC machining machine tool is the abbreviation of digital control machine tool. It is an automated machine tool equipped with a program control system. The control system can logically process programs with control codes or other symbolic instructions, decode them, express them with coded numbers, and input them into the numerical control device through the information carrier. After calculation and processing, the CNC device sends out various control signals to control the movement of getting up, and automatically processes the parts according to the shape and size required by the drawing.
In CNC processing machine tool quality appraisal cases, Zhongke Testing can provide CNC processing machine tool quality appraisal services.

was entrusted by a court to conduct product quality appraisal and analysis on 30 D model and 40 T model CNC machining machines involved in the case.
quality analysis results: The
quality analysis expert group discussed the relevant information and on-site investigation and inspection of the CNC machine tools involved in the case and made a comprehensive quality and technical analysis, and made the following suggestions and conclusions:
The equipment involved in the case has parts missing to varying degrees and does not have the ability to be used normally. Conditions for use; the missing parts include the spindle, electrical part, guide rail guard, tool holder, tool magazine, motor part, pneumatic device, and lubrication device;
The nameplates of the equipment involved in the case were all pasted with 3M double-sided tape. After tearing off, it was found that the rivet holes on the original nameplate existed. The nameplates of the equipment involved were all pasted twice. There were no signs of damage on the work surface, and no processing chips were seen inside the machine tool.
