Grinding machine quality appraisal

grinding machine is a machine tool that uses abrasive tools to grind the surface of workpieces. It mainly uses high-speed rotating grinding wheels for grinding, but there are also a few that use other abrasive tools and free abrasives such as oilstones and abrasive belts for processing, such as honing machines, super-finishing machine tools, abrasive belt grinders, grinders and polishing machines. The
grinder has a wide range of uses and is mainly used for precision machining of machine parts, including tool manufacturing and tool sharpening. For example, tool grinders are specially used for tool manufacturing and tool sharpening, including universal tool grinders, drill bit grinders, broach edge grinders, tool curve grinders, etc., which are mostly used in tool workshops of tool manufacturers and machinery manufacturing plants.
In grinder quality appraisal cases, Zhongke Testing can provide grinder quality appraisal services.

Grinding machines are broadly divided into: surface grinders, cylindrical grinders, internal cylindrical grinders, grinders, coordinate grinders, rail grinders, tool edge grinders, surface and end face grinders, crankshaft camshaft splines and roll grinders, tool grinders, super-finishing machines, internal cylindrical honing machines, cylindrical and other honing machines, polishing machines, abrasive belt polishing and grinding machine tools, etc.

The precision automatic grinder purchased by a machinery company did not meet the technical requirements stipulated in the agreement, and a dispute arose with the equipment manufacturer.
was entrusted by the court to conduct an appraisal and analysis on "whether there are quality problems" with the grinder involved in the case.
identification and analysis results: The
identification and analysis expert group discussed the relevant information and on-site investigation of the grinder involved in the case and made a comprehensive quality and technical analysis, and made the following suggestions and conclusions: The grinding machine equipment involved in the
case did not make reasonable adjustments to the oil supply volume of the lubrication system. The oil supply volume was too large and individual lubricating oil distributors leaked, resulting in invalid overflow of lubricating oil. The installation position of the lubricating oil distributor was unreasonable, making it difficult to adjust the oil volume, and there were quality problems.
