oscillating sander works

Have you wondered about how it works? We have already mentioned here that the oscillating sander works with the rotation of a spindle inside the machine. But there are some significant parts inside the machine that makes it function properly. So the essential parts of this tool are,

  • A long spindle
  • Sanding sleeves (6)
  • Throat plates (6)
  • Upper spindle washer & hex nut
  • Tabletop or counter
  • Rubber sanding drum (5)
  • Sanding drum storage peg
  • Dust collection port
  • Turning on/off switches

A long Spindle 

A long spindle sander seems to be very close to the tall wand. It is situated at the bottom of the sander. Before starting the sanding, you need to put off the spindle. Then replace the spindle with the drums. 

Sanding Sleeve

In this spindle sander, there are six types of basic sleeves. Each of them is different in their size. Sanding sleeves will help to position the drums inside the sander correctly. 

Throat Plates

With the six sizes, each of these throat plates looks like a disc. Their main purpose is to hold the adjacent drums into the sander tightly. 

Upper spindle washer & hex nut

Upper spindle washers look like oval-shaped discs. But it is very tiny. On the other hand, hex nuts are as small as nails. Both of these things are useful to join the sanding drum over the sleeves. The hex nut here acts as a door to lock all the stuff adequately. 

Tabletop or counter 

The tabletop or counter is the main platform of the spindle sander. It is the place where you need to concentrate most. Laying the workpieces over it, you’ll do the job of sanding. 

Rubber sanding drum (5)

If the tabletop is the basement of this stuff. Then the sanding drum is the soul of the oscillating sander. There are six types of sanding drums available with each tool. You require fitting them with the shapes of the workpieces. 

Sanding drum storage peg 

It is situated at the downsides of the grinding machine. The area is covered with a tall wand that is used to store the rubbing drums gradually. 

Dust collection port 

Dust collection port plays a vital role for these components. Collecting the sanding dust, grimy powders during the working period is the main aim of that stuff. 

Turning on/off switches

By turning on/ off switches, you’ll be able to stop or restart the machines frequently. So you can stop sanding in the middle of work. And again, start it when you need to.

How To Assemble Oscillating Sander
