What are the common types of grinding?

CNC grinding technology is a computer that controls the movement of a grinding wheel to precisely remove material from a workpiece. The process enables high-precision shaping and finishing of materials.

How many grinding types processes:

Surface grinding

Surface grinding is one of the machining grinding types processes that produces a smooth surface for the parts. A rotating grinding wheel grinds the workpiece surface to remove material and create a precise finish.

External grinding

External cylindrical grinding involves grinding cylindrical or rod-shaped workpieces to achieve precise dimensions and surface finish. The workpiece involved in external cylindrical grinding rotates at a specified diameter while a grinding wheel moves along its length, removing material to create a cylindrical shape. The process is ideal for producing shafts, rods, and other cylindrical components.

Centerless grinding

Centerless grinding is a machining process in which the workpiece is supported between two wheels: a grinding wheel and a regulating wheel. The rotating grinding wheel removes material from the workpiece. In comparison, the lateral movement of the regulating wheel controls the rotation speed and feed rate of the workpiece. Centerless grinding is often used for mass production of cylindrical parts with tight tolerances.

Internal grinding

Internal grinding is a process used to machine the inside surface of a workpiece. A small grinding wheel or abrasive tool is inserted into the hole and rotated to remove material and achieve the desired size and surface finish. Internal grinding is often used to produce precise internal features in components such as bearings, cylinders, and hydraulic valves.

Special grinding

Creep feed grinding is a special process of surface grinding in some grinding types, that involves removing large amounts of material at a low feed rate. The process is ideal for machining deep grooves, complex contours, and irregular shapes in difficult-to-machine materials. Creep feed grinding using a tool grinder provides high material removal rates and excellent surface finish, making it suitable for applications where productivity and precision are critical.

What are the advantages of different grinding types processes?

Precision and Accuracy: Specialty grinding including a wide range of specialized processes tailored to specific applications or materials. This may include machining such as thread grinding, gear grinding, and profiling and grinding tools, each optimized for machining specific components or achieving specific surface properties.

Versatility

CNC grinding is versatile and can accommodate a wide range of workpiece shapes, sizes, and materials.

Mass production

CNC grinding is good at high-volume production where large components must be machined accurately and efficiently。

Save costs

CNC grinding can save significant costs compared to traditional machining methods. By optimizing material usage, reducing scrap, and streamlining production processes. CNC grinding helps manufacturers increase efficiency and reduce the cost per part.

High security

CNC grinding improves workplace safety by minimizing operator exposure to hazardous processes.
