PG machining is also called Profile grinding machining or PG加工 in Japanese, it is a specialized form of precision machining used to create complex or curved contours or profiles on precision parts.

This process involves grinding the surface of a precision part to achieve the desired shape or profile.

Usually, some precision parts need to use various machining techniques such as milling, turning, grinding, or EDM (Electrical Discharge Machining). PG (profile grinding) machining is a key machining technique among them.

Unlike conventional grinding, which focuses on removing material uniformly across the surface, profile grinding is tailored to specific shapes, such as curves, angles, or intricate geometries.

PG (Profile grinding) machining is commonly used in the production of tools, dies, molds, and other components where precise shaping is critical. It offers high accuracy and repeatability, making it suitable for applications that require tight tolerances and fine surface finishes. The precision tolerance can be tolerance to ±0.002mm or ±0.001mm.

Carbide punches and die inserts are some of the main precision components that especially need the PG profile grinding machining.

PG machining optical profile grinding

CNC-controlled optical profile grinding machines are equipped with a 50x or even 100x optical magnifier that can ensure this high precision tolerance.. they are often used to automate this process, allowing for the efficient production of complex profiles with minimal operator intervention.

In optical profile grinding, the shape or profile of the grinding wheel corresponds to the desired profile of the precision parts. The grinding wheel is carefully shaped to match the contour of the optical profile being produced.

As the grinding wheel rotates, it removes material from the precision parts to form the desired profile. The process is often automated and controlled by CNC (Computer Numerical Control) machines to ensure precise and consistent results.
