Verification of the correction effect of the double-sided lap plate (shape confirmation using a straight gauge)

Confirm the shape of the reference plate that leads to deterioration of scratches and flatness with measured data.

In double-sided lapping and polishing processes, if the shape of the reference plate or polishing pad deteriorates, it can lead to scratches on the workpiece, worsened flatness, and decreased processing rates. The linked article measures a significantly deformed reference plate using a straight gauge and examines how the shape changes with dressing by a correction carrier. It also discusses the differences based on correction conditions and points to consider when applying high loads in a state of poor reference plate accuracy. This is recommended for those who want to confirm the effectiveness of reference plate correction and the importance of management before deterioration occurs. 【Features】 ■ Introduces the correction effects of double-sided lapping and polishing reference plates ■ Provides examples of measuring reference plate shapes with a straight gauge ■ Confirms dressing results using a correction carrier ■ Helps identify causes of scratches, worsened flatness, and decreased rates ■ Useful content for managing before significant shape deterioration occurs *For more details, please refer to the related links or feel free to contact us.
