Using a Double-Side Grinder to Distinctly Model Different Facets

A double-sided grinder essentially is a sturdy coarse grinding tool with two sides attached in to it. However, a double-sided grinder does come with it’s own advantages. One of these advantages is its ability to quickly and equally grind both sides of the surface together. Another advantage of a double-sided grinder machine is its ability to create uniform cuts across its flat surfaces. In this article we will discuss why it’s important to use a two-side grinder when grinding on both flat and convex surfaces.

Most two-sided grinding units will create a two-sided pattern when they are grinding. The best of these machines will also create a consistent two-sided pattern across all flat surfaces, they are grinding. For example, a two-sided chuck can be used to grind plastic or metal. When you are grinding plastic or metal you want to have a good solid double-sided grinder that can create a consistent two-sided pattern. With the best two-sided grinders a consistent two sided pattern is a definite must.

When you are using a two-sided machine to grind you need to have a good understanding of how it works. Basically two-sided machines work similar to a belt grinder. An even and smooth belt is run over the flat surface, the stone or gem is going to be ground. The belt will then move across the surface of the stone creating even and constant “wear” on the surface profiles. The two edges of the belt will then encounter each other at approximately half an inch apart.

If two-side grinders are run without a buffer, there will be an equal amount of wear on both sides of the flat surface and the areas between the two edges. This uneven wear will create “divergence” in the finish of the stone or gem. In other words, even though a given facet may produce a very smooth finish, if the flat is poorly finished, the gem will be imperfect and bumpy. On the other hand, if the two edges of the flat are rubbed too much together, the stone or gem may be rough or uneven. The two-sided grinders I use for this process to produce the best finish and most impressive lines.

To the untrained eye, both sides will have a uniform appearance, but in reality, these facets will not be totally smooth. The reason is that as the belt passes over the flat, it will cause the machine to “wear” the flat. This “wear” will cause small cracks and pits in the surface. These small cracks and pits will be visible as darker spots on the edges of the stones. The manufacturer of your machine should provide you with advice on which settings to use, how long to hold the trigger down and how long to let the blade cool between uses.

If you are unsure about what settings to use, contact your supplier or manufacturer. The two-side grinder is a simple piece of equipment to use. With a little practice and a lot of observation, you can quickly become an expert at honing gemstones and faceted metals. If you are looking for a project to get into in the craft of metal working, consider a two-side grinder.
