What Is a Grinding Machine?
A grinding machine is a machine that performs precision grinding by rotating a grinding wheel at high speed.
They demonstrate their performance on hard materials such as hardened materials and in processes that require surface roughness and precision. Depending on the type of grinding wheel, the finish of the machined surface varies, and fine finishing is also possible.
Grinding machines, however, are not suited for large cutting operations. Cutting machines such as profile milling machines, flat milling machines, and milling machines are suitable for this purpose. A grinding machines cutting edges are standardized and must be machined according to the standard.
Grinding machines are useful in many factories and manufacturing industries because they can handle materials and required accuracy that is difficult to achieve with cutting machines. In addition, advances in grinding machines have enabled faster and more efficient machining.
Uses of Grinding Machines
Grinding machines are specialized for grinding and are used to manufacture machine parts that require high precision. Grinding machines can be used to improve accuracy and surface roughness, which are difficult to achieve with cutting processes.
Grinding is located between the previous process, “cutting,” and the subsequent process, “polishing,” and can be used in conjunction with each process to improve the accuracy of parts. Grinding can provide even higher precision and surface roughness than grinding, and is performed in the finishing stage.
There are various types of grinding processes, each used to accommodate different part geometries. By combining grinding types, it is possible to accommodate parts of various shapes and produce high-precision, high-quality products.
1. Flat Surface Grinding
This type of grinding is used for machining flat parts and produces high-precision flat surfaces.
2. Cylindrical Grinding
Used to machine the outer surface of cylindrical parts to improve the accuracy of the cylinder.
3. Internal Grinding
Machines the inner surface of cylindrical parts to improve the accuracy of the inner diameter.
Principle of Grinding Machines
Grinding machines, also called grinding machines, achieve high-precision machining by rotating a grinding wheel at high speed and pressing it against the material to be machined to shave it little by little. In particular, hard parts (hardened and tempered parts, Si parts, etc.) that are difficult to cut can be machined with micron-level accuracy.
Grinding machines are used to improve flatness and parallelism, as well as to improve roundness and cylindrical shape when grinding cylindrical parts. Although the material is held in place by magnetic force during processing, ingenuity is required to grind non-magnetic materials.
Similarly, ingenuity is required in grinding non-magnetic materials such as stainless steel because they are held by magnetic force. In these situations, it is important to select the appropriate grinding method and material holding method to suit the desired processing and application.

Machines to Be Used in Conjunction With Grinding Machine
Grinding machines are machines that achieve high-precision machining, but they can also be used in conjunction with shaping machines, milling machines, grinding machines, and other machines in the manufacturing field.
1. Shaping Machine
Profile grinders are mainly used to machine the shapes of large parts. Grinding machines are specialized for precision machining, while Profile Sharpener is suitable for cutting large materials. By using both grinding machines and profile milling machines together, you can efficiently perform shape machining and high-precision finishing of large parts.
2. Milling Machine
A milling machine uses a rotating blade to shave the surface of a part. It is suitable for machining parts with complex shapes. By creating a rough shape with a milling machine before finishing with a grinding machine, efficient machining is possible.
3. Polishing Machine
Grinding machines are used to further improve the precision of parts after machining performed by grinding machines. It further polishes the high-precision parts obtained by grinding and finishes the surface. By using both grinding machines and polishing machines together, the highest quality products can be produced.
