The orbital sanding machine

The sanding machine using the mechanical action to do sanding with less human power. It reduce the operator work and give the faster and more consistent sanding then the hand sanding. The hand sanding machine works very effectively to the sanding process on the raw wood to produce a smooth and flat surface quickly with less human power. This machine is very widely used as an important tool in the woodworking industry.

Orbital sander and random orbital sanding machine are the sanding machine widely used in the woodworking industry. The orbital sander is the machine when the disk move in small circular patterns, while random orbital sanders combine random orbital and rotational movements. The orbital sander has quite high aggressiveness. If it is run with coarse sandpaper it can erode the part and form the shape. It used to do the initial sanding sand when the wood is still rough and need strong sanding. 

While the random orbital sanding machine is more used to the final sanding. The random rotation make the sanding process can occur more equally and less sensitive to the grain direction of the wood surface. The sanding process can be more even and smooth run. This makes the sanding can take place better and minimize the risk of swirl marks at the wood.

Here are tips to use the hand sanding machine

•  Avoid too strong pressure when running this machine.

The sanding process is occurring since of the rotation of the sandpaper attached to the disc. When the sandpaper rotates, the abrasive material is sanding the wood surface. Too high pressure will make the rotation of the disc become hard slow and. The high pressure also is high risk to damage the machine since the oblique disc.

• Use the coarse sandpaper to the finer gradually.

The sanding process should always be done with proper rules. The rough wood surfaces must be sanded gradually using the coarse sandpaper to the finer. The grade sandpaper cannot jump too high from the previous one. The next sanding process should be done with no more than 60 grade number.

• The orbital hand sander should be used for sanding the flat surface.

This tool should be used to sand the flat surface. You may use the orbital machine to sand the corner or edges, but it must be done carefully. The sanding on the  no flat surfaces is high risk to the over sanding. The sanding with on the no flat surface is also tending to make uneven pressure on the disc and result on the disc inclination.

•  Do the proper movement.

The movement of equipment is one important factor to obtain the optimal sanding results. Put this tool on the wood surface and then turn the engine on to make the spinning disc and then move this machine to the cover the sanding on the overall surface. Feel the movement and directly the machine smoothly and constantly to sand bit by bit throughout the overall surface. Make adjustment to the rpm of the disc to the comfortable speed if possible. The higher rpm will make the machine sand faster and tend to sand more then it need faster stroke. While the slow rpm make an easier in controlling the movement, but the sanding is also hard and slow.

•  Replace the sandpaper when it wore already.

The sandpaper work to sand the wood since it has abrasive material in it surface. When it is used then its abrasives materials wear off. The wear off sandpaper has no more ability to cut the wood. It will only rub and polish the wood to make the wood fibers lye down without being cut. The wood fibers will stand up in the stain application and make the blotchy  color. So avoid using the wear off sandpaper, make sure that you use the good sandpaper that is still available to cutting the wood fibers.
