Random orbital Sanders is hand held power tools for sanding using a continuous-axis or circular motion. In this case, the sanding stroke is delivered by a random orbital motion. This is because the angle of rotation of both the head and the rotating disc is variable. The two are controlled by means of a rotary or linear control device mounted on the machine. This technology was initially used in the early 1968’s by Rupes Tools Co. as part of their line of reciprocating Sanders.
The advantages of using random orbital Sanders over other types of hand held Sanders in today’s market are numerous. They offer a much more ergonomic approach to sanding, particularly when it comes to preparing interior surfaces such as automobile and boat doors. It can also be used to sand doors and windows on boats and RV’s. These types of machines have also been used to sand aircraft seats due to the large surface area. Another advantage of these Sanders is that they provide a higher level of performance than some of the popular reciprocating hand held Sanders on the market. Because of their dual spinning motion, many random orbital Sanders can perform in the same capacity as some of the much more expensive reciprocating hand held Sanders on the market today.
While there are many different types of Sanders available, one of the most popular is the round orbital Sanders. There are several different types of round Sanders, including: flat-disk Sanders, which are similar to a cordless, rim-mounted sander, but have a disk that is not rounded; and, spindle-screw powered, which are different from other spindle-screw powered Sanders in that the drive mechanism is a screw thread that fits into a cap. All of these are available with different sized nozzles, giving all the users a wide range of versatility. Spindle-screw powered Sanders are also commonly found in applications where durability and accuracy are extremely important. For example, many government contractors use these types of machines for large-scale buildings and structures because of the increased accuracy in their operation.
One of the most common uses of an orbital sander is that it is a very efficient power tool, especially when it comes to demolition or sanding. Unlike a hand held sandpaper, an orbital sander will not lose its effectiveness over time. Because the sander has such high speeds of speed and rapid rotation, it is capable of quickly and efficiently removing many layers of wood, stone, or concrete by simply using one panel at a time. Some examples of these are: boat foundations, bridge foundations, parking lot repairs, asphalt patios, building facades, and more. Because the sander utilizes sandpaper particles, there is not a need to purchase and store huge amounts of sand, and the dust is much smaller than those from other handheld sandpaper products.
There are two main types of orbital Sanders: electric and belt Sanders. Both of these machines work using a similar mechanism to the one used in hand held Sanders. Belt Sanders is generally found in applications where the sander will perform multiple actions at once (such as sanding and grinding) and will be incredibly hard on materials. While this can be advantageous, there is generally only one flat belt that can be used at a time, limiting the ability to perform multiple actions at the same time (such as sawing). The electric sander works in a different way: it has two flat belts (one for each sanding action), and multiple brushes that can rotate in order to complete different types of sanding.
Palm Sanders does not have the rotating flat belts that the orbital Sanders have, but instead use a vibration system that vibrates the palm between the parallel bars. While the palm action is more convenient, this type of sander is generally not as powerful as its orbital counterpart and tends to be used for less complex projects. Palm Sanders can also be a challenge to repair, as they tend to get worn down by constant vibrations. Overall, both of these machines make fine sanding tools that can be very useful for many applications.
