I am never too busy for any matching projects

Philip Yaghmai - Project Engineer

My manufacturing engineering department was responsible for developing the best process for polishing of computer disks. This involved a detailed study of:

1-  Pressure applied from the pads to the disk

2-  RPM of the Disk

3-  RPM of the Upper Pads

4-  Rotation direction of the Disk

6-  Rotation direction of the Upper Pads

7-  Rotation direction of the Lower Pads

8-  Grid Size and Grid Material of Pads

9-  Polishing Fluid Chemistry

10-Polishing Fluid GPM and Pressure.

11-Pads’ Size

12-Pad to Disk Location

13-Pads’ Grooves’ Geometry

14-Pads’ Profile
