Profile grinding refers to a process in which a product is optically overlaid on a projection drawing of a target shape called the profile, and then ground accordingly with a fine grinding stone. This process is also known as copy grinding and is a powerful technique for machining precision mold parts.

Profile grinding is generally said to produce more jagged surface roughness than form grinding since finishing is done with a jagged grinding stone. However, Shin-Nihon Tech’s non-polishing process can produce a polished surface with a surface roughness (Ry) no greater than 0.2 micrometers by combining the latest computer numerically controlled profile grinder and their own machining technology.

This method also prevents powder generation and burning during pressing, improves the quality of pressed products, and extends the working life of molds. In addition, this is easier on the environment as press work cannot be performed without blanking oil, thus eliminating the need to clean with chlorofluorocarbons.

Punching or cutting paper, film or similar material with a blade of a prescribed shape (usually a Thomson blade) is called die cutting. The mold employed is usually referred to as a "die" .

This mold is typically made by incorporating a Thomson blade into a base of plywood or other material. However, Shin-Nihon Tech uses an integrated Thomson punch characterized by cutting a single piece of hardened material to form the blade.

This blade has a high hardness of at least HRC 56, which ensures that it will retain sharpness over a long working life. In addition, thanks to their high-speed machining center, the blade can be shaped to micrometer precision and cutting-edge height control.

When this integrated Thomson punch is incorporated into a progressive die, the press work can produce extremely fine die cutting.
