A reliable integrated production system that achieves high quality and low cost.
We strictly control all processes from raw material processing to finishing.
In order to provide high-quality products more speedily and at lower cost, it is necessary to implement integrated production from raw material processing to finished-product processing in-house. We have been working on building an "automated, integrated production system" from an early stage. We will continue to improve our production processes in order to respond to the diversifying and increasingly precise needs of our customers.
Pinion Gear
Cutting and drilling process
Round bars are cut to specified sizes and holes are drilled in the inner diameter.
Lathe process
The outside diameter, inner diameter and end face are machined using lathe, and finished to the size of the product.
Hobbing
Tooth cutting processing is performed with a hobbing machine.
Allows processing with high precision and speed.
Chamfering process
This process removes burr generated during hobbing.
Shaving process
The tooth surface is finished using shaving.
Since the tooth surface is finished before heat treatment, the target value is set considering distortion caused by heat treatment.
Heat treatment process
Carburizing treatment is applied to increase surface hardness and enhance product strength. At the same time, we perform shot blast treatment to remove scale and burrs.
End surface grinding process
The end face is ground with an end face grinder to provide finishing to the total length dimension and surface roughness.
Inner diameter grinding process
The inner diameter is ground using a honing machine to provide finishing to the inner diameter dimensions and surface roughness.
Cleaning process
Foreign matter is removed using a cleaning machine, followed by application of anti-rust oil.
Meshing inspection process
A dedicated gear checker performs meshing inspection and check all gears for dents and scratches.
