A cutting wire supported at two points hollows out the bottom of a carbonaceous raw material during rotation.

A tool holder with a removable handle allows efficient tap extraction by enabling the handle to spin the tap out after threading.

Periodic cutting amount variation suppresses chattering in thread cutting without detectors, preventing phase errors and reducing tool wear.

Segmenting the double-layer configuration into independent axes eliminates vibration while forming internal threads without chip generation.

A universal flexure component integrates with tap driver central bodies to ensure precise alignment during rigid tapping operations.

Segmented thread-creating tools eliminate starting cones, reducing tool length and cycle time while ensuring precise axial positioning in blind holes.

Movable friction face releases small holesaws without tools, resolving securing force versus removal difficulty.

Merging linear and rotary actuation into one component reduces structural complexity while maintaining precise motion control for machine tool operations.

Segmented arbor with spring-loaded pins prevents thread lock-up and off-axis wobble in small hole saws.

Electromagnetic torque motor integrates directly with the milling machine whirling unit to drive the receptacle without external components.

A reference hole guides the tool shaft to prevent bending and vibration, enabling high depth-to-diameter ratio machining.

Segmentation isolates the oil reservoir from the main housing, preventing spillage during transport while maintaining structural support.
