An automated stroke polisher for metal sheet.
The operator loads the sheet over a fixed table using handling devices, then sets the height depending on the thickness of material, and activates the polishing cycle. Then the machine moves the metal sheet over to the homing position. The carriage with its polishing wheel will then start to stroke along the length of the sheet. As the polishing carriage continues multiple strokes, the polisher moves laterally along the width axis of the sheet to polish the full surface. When the sheet is completely polished, the machine and carriage return to home position and wait for the next cycle to start. It would be possible for the operator to make more than one pass per cycle if required.
