Grinding operations of planar or flat surfaces are called surface grinding. For this purpose, two general-purpose surface grinder types have been developed. One type with s reciprocating table and another type with a rotating table. Each machine has the option of horizontally or vertically changing the grinding spindle.
In the fundamental meaning, precise surface grinding is used for two things: making the square metal and the parallel cube. At first glance, the surface grinding service can be used for many applications, but it is usually used for fixtures, molds and dies, so it looks simple, but is it ? In this article, we will discuss the main applications of surface grinders and provide you with some tips on how to improve machine performance.
For six-sided cubic rectangular or square metal sheets, precision surface grinders allow you to make each side square and parallel to itself or the reference surface. These square or rectangular blocks are usually fixed to the grinding table with magnets, so one of your flat surfaces is close to the other. On this critical basis, surface grinding may be invaluable for applications such as mold making. The required positional accuracy of the mold used in extrusion and injection molding means that the mold must be at right angles to the outside of the center, which is what precision surface grinding can provide. You simply cannot grind a block of metal as square and precise as on the surface—not to mention, the ground surface will never match the polished surface, resulting in a smooth and low Ra value.
A precision surface grinder can also be used on the rod, although the outer diameter of the rod cannot be rounded; in order to accomplish this task, OD grinding (also known as cylindrical grinding) is used. However, surface grinding can make both ends of the rod completely perpendicular to the outer diameter. However, surface grinding can make both ends of the rod completely perpendicular to the outer diameter. Here, the V-shaped block is used to position the grinding rod. Put the round rod into the V-shaped cavity, and fix the rod vertically in place with a clamp. From there, precision surface grinding can be used to grind the top of the rod to a size that is completely at right angles to the outer diameter.
Regardless of the size of the part to be ground, the concept of surface grinding is the same. However, like many machine tools, the size range of surface grinders can range from small to large. As the size of surface grinders increases, there is a trade-off between tolerances. However, if your parts are large, it is best to use a surface grinder on a larger surface area. The largest end is the Blanchard grinder, which is an older technology. Although its rotating disc produces very different surface finish patterns, it is considered surface grinding.

Although there are manual surface grinding tools, a key function of the surface grinding service is to remove small amounts of material accurately and repeatedly through the machine. Here, the fewer the number of removals, the better the surface finish and dimensional accuracy. It is not recommended to remove a lot of material thickness in one go, as this will result in poor surface finish. In addition, applying this type of stress on both the metal and the machine can result in poor positioning accuracy and may cause the workpiece to crack. Instead, it is much better to perform many repeated passes, removing more material with each pass. This makes watching an automatic surface grinder look like watching a perfectly choreographed, fast, and repetitive side-to-side movement, where each interval is moved slightly down into the metal part without being noticeable, and a very small amount of material is removed with each pass. When the machine performs its tasks, it will not be accompanied by vibration and noise caused by rotation. An exception is this incremental material removal in the form of creep feed grinding, which is a precision surface grinding method that was originally designed to remove large amounts of material in one pass.
