Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a CNC forming grinder with a positioning structure. Background Art

[0002] In modern manufacturing, cutting tools are essential tools for machining. Their quality and performance directly impact the efficiency of the entire machining process and product quality. Therefore, improving tool production efficiency and machining quality is a key development direction for the manufacturing industry. CNC grinding machines, as a key piece of equipment for modern tool processing, offer advantages such as high precision, high efficiency, and a high degree of automation. However, in practice, CNC grinding machines face challenges when machining tools of varying diameters.

[0003] In the prior art, positioning jigs are commonly used to position the tool being machined. However, because different tool shanks have varying diameters, tool machining on a CNC grinder requires frequent jig replacement and recalibration. This not only increases operator workload, but also reduces production efficiency and increases costs.

[0004] The frequent need to replace positioning jigs and recalibrate tools significantly reduces the productivity of CNC grinders when processing tools of varying diameters. This not only impacts the company's normal production schedule but also increases production costs. The process of replacing positioning jigs and recalibrating tools is complex and tedious, requiring operators with high technical skills and extensive experience. This not only increases the operator's workload but can also lead to operational errors and inconsistent machining quality. Frequent replacement of positioning jigs and recalibration not only increases operating time but can also lead to increased equipment wear and tool scrap rates. These factors further increase the company's production costs. Utility Model Content
