Abstract:  
Disclosed herein is a surface treatment machine that enables the inhibition or reduction of residual abrasives that remain on a workpiece that has been surface treated. An H steel (a workpiece to be treated) is conveyed by means of a conveying device. Blasting devices are then projected abrasives on to the conveying H steel such that it is surface treated. In the downstream of the blasting devices along the conveying direction, a blowing port of an air blower is located above a conveying path to blow the gas to the upper surface of the H steel such that the abrasives on the H steel are blown off and removed therefrom.
