1 Sanding Surface Preparation Peter Van Dyke

2 Sanding What is different about sanding and finishing operations?

3 Considerations Labor Consistent results (hand sanding) Dust Abrasive costs discs are expensive Work man s comp claims Through put

4 What is a Good Surface Finish? True final scratch 180 is really 180 Grit sequence Abrasives Sanding heads Drums Pads Reduce fiber raise hour window Proper grit sequencing deep scratches not removed Poor grit sequencing

5 What is a Good Surface Finish? Free from defects reading the panel What is a defect? Chatter Stripping Chicken Scratch Oscillation Lines Shadows Cross Grain

6 What is a Good Surface Finish? Meet customer needs Internal External Subjective

7 Audit The Process Calibration sanders Story boards Segmented pad sanders Pencil test One head at a time Results from all heads Random quality checks

8 Trouble Shooting Reading the panel Defects that move Related to the abrasive belt Defects that do not move Machine related Machine adjustments Maintenance (i.e. heads, hold downs, etc.) Parameters (i.e. fall/ rise, edges, etc.)
