Description

Technical Field

[0001] The invention belongs to the technical field of grinders, and in particular relates to a double-sided grinder. Background Art

[0002] A grinder is a device used for precision machining of workpiece surfaces. It is widely used in electronics, optics, mechanical manufacturing and other fields. Its core function is to grind flat and curved surfaces of workpieces through the rotation of the grinding disc, in combination with grinding fluid and abrasive particles, to achieve the specified surface roughness, flatness, parallelism and other precision requirements. In scenarios such as semiconductor wafer processing, optical lens grinding, and precision mechanical parts manufacturing, the processing accuracy and efficiency of the grinder directly affect the performance and quality of the product. Existing grinders still have the following problems in practical applications: traditional grinding process planning often relies on the operator's experience, lacks scientific algorithm support based on workpiece material properties (such as hardness, elastic modulus) and grinding quality requirements, and is difficult to formulate personalized grinding plans for workpieces with different materials and precision requirements, resulting in poor process adaptability. During the grinding process, the adjustment of process parameters (such as grinding pressure, speed, and time) mainly relies on manual judgment, and dynamic feedback control cannot be performed according to the real-time status of the workpiece surface. Improper parameter settings can easily lead to problems such as substandard surface roughness and uneven material removal, affecting the stability of processing quality. In addition, frequent manual intervention not only increases operating costs, but may also lead to low processing efficiency and increased scrap rate due to human errors, making it difficult to meet the needs of high-precision and large-scale production.
