Three Quality Inspection Steps Analysis of CNC Flame Cutting Machine Parts

Sampling inspection is the final threshold for the inspection of workpieces. It is necessary to measure the specific dimensions of the slit width, flatness and verticality of the workpiece to determine whether the processing quality can meet the secondary processing requirements. Traditional flame cutting is operationally controlled by the use of compensation, and the quality of the cutting is highly variable due to the operator's experience. The CNC flame cutting machine integrated with the CNC active system displays the cutting quality in the cutting efficiency. Relatively unchanged, the quality inspection of the workpieces constitutes a relatively solid inspection step.
Step by step, appearance reflection

Appearance reflection is the inspection of the cutting surface of the steel after the end of the cutting. Regarding the cutting and processing of the standard, the cutting surface should have no cracks, and there is no slag inclusion and ribs larger than 1mm. After reaching the above requirements, Step 2 is executed. Otherwise, the relevant parameters of the cutting process are required to be cut again after the new review.

Step 2, sampling test

Sampling inspection is the final threshold for the inspection of workpieces. It is necessary to measure the specific dimensions of the slit width, flatness and verticality of the workpiece to determine whether the processing quality can meet the secondary processing requirements. The detailed sampling test includes the dimensions of the parts after cutting, the section brightness, the groove, the verticality of the fracture, the bickering degree, the blunt edge height, the partial notch, the burr and the residual oxide. The user can find the relevant quality to limit the deviation. Reference specification.

Step three, write off the mark

In the case of a large amount of cutting tasks, the inspection of the machined parts cannot be inspected one by one. In order to facilitate the later inquiries, it is required to indicate the engineering title, part number and the assigned team on the cutting piece for later check. Of course, here we ask the operator to complete at least the sampling inspection before the next batch of cutting processing. The numerical control flame cutting machine should be calibrated to show that the cutting quality does not meet the requirements, so as to avoid the appearance of many failed workpieces.
