Stainless steel workpiece surface, most of the requirements are smooth and flat, the steel itself is thicker, the welding scar is also relatively thick.
The use of general sandpaper sanding will be more waste of time, so the choice of hundred blade sanding, hundred blade cutting force compared to the plane of the sandpaper, cutting more powerful, stronger, for thicker weld scars, very suitable for sanding.
The cutting force of 100 blades is more powerful and stronger than that of flat sandpaper, which is very suitable for grinding thicker weld scars.
After cutting off most of the weld scars with the 100-blade, then use the nylon sheet for sanding, you can easily sand off the residual weld scars without damaging the workpiece.
