Manufacturing process flow

This a machining method in which tools are used to cut part of workpieces to create products of the prescribed shape, dimensions, and surface roughness.
Lathe turning, drilling, and milling are examples of cutting.

This is a machining method which involves using a grinding wheel rotating at high speeds to grind the surface of workpieces.
Machining accuracy is high, and therefore it is used for the finishing of locations which demand micron-level accuracy.
Cylindrical grinding, end face grinding, and multi-wheel grinding are examples of grinding.

This is a machining method which involves rapidly cooling workpieces from the prescribed high-temperature state to increase their hardness.
It is used to improve fatigue resistance and wear resistance.
Induction hardening and TIG hardening are examples of hardening.

Inspection involves checking whether the machining accuracy and appearance of workpieces meets quality standards at an appropriate frequency.
With important processes, machining conditions are also checked periodically to prevent non-conforming products before they occur.
Accuracy inspection, visual appearance inspection, and machining conditions inspection are examples of inspection.
