Flat bar and square tube polishing machines are robustly constructed, making them ideal for heavy-duty polishing of bars and rectangular tubes. These machines are capable of handling workpieces up to 150 in width, utilizing a combination of an abrasive belt and an abrasive brush for optimal performance.

The flat surface polishing machine is primarily designed for flat surface finishing applications, including finishing and deburring of strips, as well as satin and bright finishing of square tubes and pipes.

No.4 and hairline finish:

1. Utilize a sand belt to remove scratches and sand holes on the surface of the workpiece (No.4 finish).
2. Use a nylon wheel to achieve a brushed effect (hairline finish).
