In the sanding process, you may encounter many problems. One of them is the wood fiber which stands back up after being sanded. This condition will make the sanded surface layer imperfect, also reducing its aesthetic value.

To produce a perfect product is not easy, because you need to go through a fairly long process starting from selecting materials, sanding, and finishing. You often come across panels that have been sanded but still feel that they have a rough surface.

When the surface feels rough, the production process will be slightly hampered because you need to re-sand the repair part, which will cost more money and additional time. So, what if one day you experience this while undergoing the production process?

No need to worry, you can avoid or reduce these problems by anticipating the sanding process before the problem occurs. Considering that the wood fiber is different for each type of wood, there is teak wood fiber, mahogany wood fiber, pine wood fiber, and other wood fibers, you need to note the following things.

Inappropriate grit combination
The use of inappropriate grit is often found in several large companies. Because they wanted to speed up the sanding process, they ended up jumping too far in the grit process. For example, at the beginning of the sanding process, #80 was carried out with an abrasive force of 0.6 mm. Then, proceed directly to #240 which has an abrasive power of 0.10 mm, so that the wood fibers caused by grit 80 cannot be removed optimally by grit 180.
To avoid this, there are solutions you can do. It is necessary to change the grit jumps not too far, for example like 80-120-180 and so on. Why is that? Because the ideal grit combination is grit that performs one jump in the sequence.

The sanding speed (cutting speed) is inadequate and the conveyor speed is too high
If you are sanding using a machine to deal with wood grain problems, it is best to use a high speed to start the sanding process on hardwood. Apart from that, also pay attention to slowing down the conveyor speed so that it can scrape the surface and handle the wood fibers optimally. Apart from cutting speed and conveyor issues, wood humidity also needs to be considered when storing wood before and after sanding.

To anticipate this, you can use plastic wrapping by wrapping a stack of panels that have gone through the sanding process but have not yet continued to the next process. This is done so that the temperature of the wood is always maintained.
