The measures for scratches on double-sided lap and polish start with confirming the flatness accuracy.
Confirming the deterioration of yield in double-sided lap and polish processing from the shape of the reference plate.
When issues such as scratches, deterioration of parallelism, and decreased processing rates occur due to double-sided lapping and polishing, it is important to check not only the processing conditions but also the accuracy of the reference plate. The reference plate measurement straight gauge is a measuring tool that allows you to check the shape simply by placing it on the reference plate. The long type is suitable for understanding the shape of the entire reference plate, while the short type is ideal for grasping the shape of the band width, which is more likely to affect the finish of the workpiece. By confirming the shape of the reference plate numerically, it helps determine whether adjustments can be made based on carrier conditions or if truing is necessary. 【Features】 ■ Supports accuracy verification of double-sided lapping and polishing reference plates ■ Assists in identifying the causes of scratches, deterioration of parallelism, and rate reduction ■ Understands the shape of the entire reference plate with the long type ■ Checks the band width shape and the fit of the upper and lower reference plates with the short type ■ Custom design and manufacturing are possible to match the machine used and the size of the reference plate *For more details, please refer to the related links or feel free to contact us.
