Different Power Sanders Types

December 31st, 2009 No comments

Wood working and mill working makes it necessary to use power sanders. There are many variations of this machine and one needs to be careful to select one that best suits the kind of jobs handled more frequently. Here are the most often employed sanders, each useful for a set of different jobs. Get familiar with these and the kind of operations they are suited to perform and choose the one that best meets your job requirements.

Belt Sanders

These are probably the most elementary sanders and common people often associate a sander to belt sander. Here, sandpaper is looped around two wheels. As the mechanism starts the sandpaper spins around at very high speeds. Such sanders are useful for heavy-duty jobs, meaning they are employed to primarily make a surface ready for the next operation on another finer machine, which couldn’t be employed for such preliminaries for economical reasons as working on finer machines is slow and more expensive. For instance, for removing of old paint or stains from the given piece would be much faster and economical on a belt sander than on any other sander. One has to be very careful and attentive while operating such aggressive sanders. Else, you need to have a sander that offers the function of variable speed or get one that operates on slow speed.

A narrow belt sander is a variation of belt sander. It has similar features except that it is not as wide and thus more suited for small and difficult-to-reach areas.

Palm Sanders

Palm sanders are also known as finish sanders, or pad sanders. They house a small rectangular pad at the bottom that would generally take about a 1/4 or 1/3 sheet of sandpaper. It vibrates in a rather circular manner, and needs to be moved along the wood in the same circular motion to avoid scratching. A proper handling gives a good smooth finish to flat and easily accessible surfaces. This is an ideal sander for a follow up operation after having done the primary heavy-duty job on a belt sander.

Detail Sanders

Also referred to as a contour sander, detail sanders are small sized, compared to other hand held sanders. You need them for sanding tight narrower spaces or for sanding of unusual shapes that other sanders are incapable of. Generally, they have a triangular shaped pad that facilitates approaching nooks and corners. The modern versions of these sanders come with multiple attachments and depending on the complexity of job one can opt for a suitable attachment. They find a wide application in small craft jobs and mill working like window and door casings.

Random Orbit Sander

Random orbit sanders offer the most versatile operations. They may be employed for execution of big jobs and remain equally good for assignments needing sanding of small narrow spaces. It can surely be classified as an all-purpose sander. Such sanders are provided with a round pad moving in a circular manner but with a bit of random variation that helps to avoid getting spin marks on the work piece. The motor of these senders is provided with speed control feature that proves very helpful while working on softer verities of wood or while approaching the end of your sandpaper. The random orbit sanders have built in arrangements for collection of dust. It may have a dust collection bag or an attachment in the form of a vacuum hose. However, for dust collection feature you have to use special-purpose sandpaper. This is how the dust collection mechanism works: The circular pad has small holes that suck the dust as soon as it is created. There are corresponding holes on the sandpaper, thus all the dust gets collected while the machine is operative.

Because of the multi-purpose functions that a random orbit sander is designed to perform, it would ideally suit those looking for an all-around sander.
