A cup spring — also known as a Belleville washer or disc spring — is a conical washer-type spring that generates a high clamping or preload force within a compact axial space. In cutting cart assemblies like the KV750, cup springs are used to maintain consistent tension or positional load on fasteners, shafts, or clamping mechanisms. When a cup spring loses its shape through fatigue or overload, the assembly may develop looseness, vibration, or inconsistent blade positioning, making timely replacement important to maintaining safe and accurate cutting performance.
