Grinding

In industrial production , the grinder is a machine tool that can make the correction . This machine tool uses a grinding wheel to produce a perfect surface after machining by a milling machine or a turn .

There are two types of grinding:

1)the surface grinder,

2)The cylindrical grinding.

Surface grinder:

  "Surface Grinder" is commonly used to denote the surface grinder. This term implies, in the current technical use, the grinding surfaces are substantially planar. Several methods of surface grinding are adapted and used to produce surfaces characterized by elements in parallel lines and right angles. Naturally, one can obtain precision surfaces which may consist of long, straight pieces at different angles (such as guides the carriage of a tower, blades and tools of all kinds, for example). In other cases, we obtain curved surfaces or profiled.

The third type of grinder is a grinding machine, but it is equipped with a rotating flat table. Often used for surfacing the blades and industrial knives.

Advantages of the surface grinder 

Alternative methods for engineering surfaces similar to those obtained with a grinder is the use of a milling machine and a much more limited degree, the "Glider". However, the grinder has a clear advantage over alternative methods with respect to cutting tools. Examples of potential benefits:

Rectifier is applicable on hard or abrasive materials without significant effect on the efficiency of removal of material.

The desired shape and dimensional level of the work surface can be obtained at a higher level and in a manner more consistent.

Surfaces of a high precision finished, when using the appropriate system, are produced.

Tooling costs for grinding are relatively cheaper than other machine tools.

Fixing parts is generally very simple. Especially when a magnetic platform is installed on the crossing of the grinder.

Main systems of surface grinding 

Flat surfaces can be corrected using different sides of the wheel by various arrangements of the table, the wheel and the reciprocating movement. Most systems include surface grinding, with their respective capabilities, work on two major distinct characteristics:

The operation surface of the grinding wheel , or can be its periphery its face (side)

The table movement during labor may be transverse (usually reciprocal) or rotation (continu.
