Conveyor

First check whether the conveyor belt is damaged, the damage of the conveyor belt will affect the amount of sand cut. Next, check whether the edge of the conveyor belt is warped. The warping of the conveyor belt proves that the service life of the conveyor belt has expired and the conveyor belt needs to be replaced. Warped edges will result in inconsistent thickness of the produced sheet.

Conveyor platform

The conveying platform of the broadband sander is divided into marble countertops and metal countertops. If it is a marble countertop, be sure to check whether the marble is broken and whether the iron hoop around the marble is glued. Breaking the glue will first affect safety, and second, unless the entire conveyor bed is replaced, the quality of the plates produced will definitely not meet the standard. If the machine is not properly protected during delivery, it is very easy to cause damage to the marble countertop during transportation! If it is a metal table, just observe whether it is flat.

Sanding roller

Sanding rollers generally have metal rollers, hard rubber rollers, and soft rubber rollers.

Metal rollers generally do not have the problem of bumping. Even if there is bumping, the metal reflection is easy to see. The metal roller can be touched by hand without wear and tear.

For the hard rubber roller, touch it with your hands for wear, and check whether the roller body is cracked (the hard rubber roller is easy to crack if the sander is not used for a long time, which will seriously affect the quality of the board).

Soft rubber roller, generally used for polishing, is also the most easily damaged one among the three types. It is extremely soft. Carefully observe whether there are scratches and whether the roller body is damaged.
