Boring machine quality appraisal

boring machine is a machine tool used for processing inner circles, spherical surfaces and other workpieces. Its advantages are high precision, the ability to process deeper holes and thin-walled holes, and the ability to process holes with special shapes.
boring machine is widely used in industrial production in automobile, machinery, aviation, aerospace and other industries, and is used to process inner circles, spherical surfaces, oblique holes and special holes of various sizes and shapes. Its characteristics of high precision, high efficiency and high stability have been widely recognized.
In boring machine quality appraisal cases, Zhongke Testing can provide boring machine quality appraisal services.

1, boring machine workbench for visual appearance inspection. Use the naked eye or a magnifying glass to check for problems exposed on the surface of machine tool castings, such as deformation, cracks, shrinkage cavities, pores, slag holes, blisters, iron beans, sand inclusions, sand sticking, cold insulation, insufficient pouring, etc. And check whether the markings and furnace numbers are correct and complete, etc. Can preliminarily distinguish qualified, repaired and scrap products.
2, fluorescence inspection of boring machine workbench. It is suitable for surface inspection of various grades of alloy machine tool castings. It can detect relatively small (002~005mm) surface problems that are generally invisible to the naked eye, such as cracks, cold shut, oxidation, etc.
3, boring machine workbench coloring inspection (flaw detection): mainly inspects problems exposed on the surface of machine tool castings.
4, kerosene infiltration inspection of boring machine table. It can check the boring machine table for cracks, shrinkage and other problems.
5, magnetic particle inspection of boring machine table. Tiny problems as small as a few microns can be found. It can check the cracks, cold insulation, pores, slag inclusions, etc. of gray iron castings.

The boring machine purchased by a heavy industry company had problems such as oil leakage, the spindle claws were not in place, the touch screen had not been debugged, the column had dents, and the control button station wiring was confusing, etc., which led to a dispute with the equipment manufacturer.
was entrusted by the court to conduct an appraisal and analysis on "whether there are quality problems" with the boring machine involved in the case.
appraisal analysis results: The
appraisal analysis expert group discussed the relevant information and on-site investigation of the boring machine involved in the case and made a comprehensive quality and technical analysis, and made the following suggestions and conclusions:
The boring machine involved in the case has a tool handle fixation problem, a large reset error in the
