Description

Technical Field

[0001] The utility model relates to the technical field of grinding processing, in particular to an online detection device for the grinding removal amount of a precision grinding machine. Background Art

[0002] A double-disc grinder is a type of grinding equipment commonly used for machining flat surfaces. It uses two grinding discs to sandwich the product to be ground, then drives the two grinding discs in opposite directions to grind the product to achieve the desired grinding effect. Among the product grinding parameters, grinding thickness, also known as grinding removal, refers to the thickness of material removed from the workpiece during the grinding process. This parameter directly reflects the depth and effectiveness of the grinding process and has a significant impact on product quality indicators such as precision and surface roughness.

[0003] Currently, in traditional twin-disc grinding machines, the lower grinding disc is typically fixed, while the upper grinding disc is driven by a cylinder to raise and lower the disc and apply pressure to the disc. The amount of material removed from the product is calculated based on the grinding time. However, this removal calculation method becomes uncontrollable due to grinding disc wear and changes in the grinding fluid temperature, resulting in large errors in the calculated removal amount. Given the increasingly high precision requirements for grinding products on the market, the traditional twin-disc grinding machine's method of calculating removal amount based on grinding time can no longer meet product processing needs.
