CNC sliding headstock lathes are becoming more popular among traditional machine shops for their multitasking capabilities, some offering B-axis milling spindles.
Watch a dental implant being machined
This video shows a variety of operations used to machine a dental implant component complete on a Tornos EvoDeco 16 Swiss-type as well as the action of the sliding headstock design.
Swiss-types with B-axis toolchanger
Marubeni Citizen-Cincom’s L20XII ATC is an example of a Swiss-type with a B-axis automatic tool changer. The ATC tools can be preset offline for fast setups while enabling the complete machining of complex geometry as is common to medical implants.
Thread whirling and turning performed simultaneously
For deep thread forms, thread whirling attachments can be effective. Unlike single-point threading, thread whirling units have multiple cutting inserts mounted inside a rotating ring. The thread whirling ring rotates around a cylindrical component to cut even complex double threads in one pass.
