Polishing is a process that can either be done by hand or with a polishing machine. The aim of polishing is to create a shiny and smooth surface of an object by rubbing it or using some sort of chemical action. Once polished a surface will have a significant specular reflection. With objects made from materials such as glass, metal or stone, the polishing process will also reduce the diffuse reflection to a minimum.

In order to fully understand what happens to a surface when it is polished you need to take a look at the surface whilst it is unpolished. If you magnify this surface a couple of thousand times it will look like valleys and mountains. After polishing these valleys and mountains will just look like small hills or be flat. This is what happens when you polish with abrasives starting with coarse abrasives and ending with finer abrasives.
There are many applications for polishing such as with metal work, wood work and stone work And because each application has different requirements the polishing machine for these tasks will differ and have different designs to adapt to the job in hand. But despite the polishing machine being different for each application, the fundamental basics of polishing remain the same.
Polishing is not difficult to master and with the correct accessories such as abrasives and waxes anyone can do it to a very high standard by hand. But with a polishing machine the job can be done even better in a shorter amount of time. Polishing machines have been designed and manufactured by their relative companies to be user friendly and very easy to use. So if you have never used a polishing machine before, do not be daunted by the prospect of using one. Each machine, no matter which type and for which purpose, will come with an operators manual which you should read before using your particular machine. As with any powered machine it is always a very good idea for familiarize yourself completely with all the working parts, functions and maintenance issues of your particular polishing machine. Along with this familiarization and proper care and maintenance of your machine, will ensure you a safe and long working relationship with your polishing machine.

Types Of Polishing Machine

The polishing machine is a machine that has been specifically designed to use for polishing surfaces of numerous articles. Each polishing machine has it’s own individual characteristics dependant upon it’s intended use.. As well as there being machines of very simple design, there are also polishing machines with laps, wet blasting machines and centrifugal machines.

With a polishing machine that has laps the polishing is done by having a rotating lap attached and mounted on to a spindle on the machine. Here the item that requires polishing is secured, usually to a workbench of some shape or form, and the lap is moved over the surface of this item doing the polishing. The laps for these polishing machines tend to be made from soft metal, wood, felt or leather. When using the laps you can either bond the polishing and lapping materials to the laps themselves or you can wait and add the materials during the finishing process.

A wet blasting polishing machine is where an item that needs polishing is placed inside a chamber. The item is then blasted with jets of liquid that are saturated with an abrasive of some sort. The muzzle of this type of polishing machine will work its way slowly along the whole length of the item continually pushing out jets of the abrasive mixed liquid throughout the whole polishing process.

A centrifugal polishing machine is one that is used to polish items that are of a complex design. They have a container that is filled with an abrasive powder of some sort or suspension. Inside the chamber the item that needs to be polished is fixed and the container rotates. Whilst rotating the abrasive inside the container moves freely and polishes the item.
