　➀　Turning

Turning is a process in which material is rotated on a lathe and cut with a tool for precise finishing of cylindrical parts. Because it can
accommodate a wide variety of shapes—such as outer diameters, inner diameters, grooves, and tapers—it is a fundamental and essential
process in metalworking.

　➁　Gear Cutting

Gear cutting machines are dedicated machines used to cut gear tooth profiles. Generally, cutting methods such as generating gear cutting are used to accurately cut tooth profiles from raw material, producing high‑precision gears.

　➂　Heat treatment

Heat treatment is a surface treatment technology that optimizes material properties by heating metal to high temperatures and controlling the cooling method. This process significantly improves the hardness, wear resistance, tensile strength, and fatigue strength of steel materials.

　➃　Grinding

Grinding is a process in which a grinding wheel is used for precise finishing of metal surfaces, achieving high dimensional accuracy and
smoothness. Gear grinding is a specialized grinding technique for gears that further refines tooth surfaces after gear cutting, improving quiet
operation and durability.

In-house manufacturing of a spiral bevel cutter

In-house manufacturing of a spiral bevel cutter for about 40 years.
We realized small lots, a wide variety of products, and quick delivery by in-house manufacturing of jigs for each process.
