Swiss-Types

Swiss-Types Offer Advantages Beyond Watchmaking

Derek Korn | Production Machining magazine

CNC sliding headstock lathes are becoming more popular among traditional machine shops for their multitasking capabilities, some offering B-axis milling spindles.

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.

High-Production Multitasking

Platforms such as multi-spindles and rotary transfer machines remain well-suited for high-volume production, but are now more accommodating to smaller batch sizes.

Metal Additive Manufacturing

Why are an increasing number of machine tool builders adding additive manufacturing to their equipment’s already versatile machining capabilities? Because additive and subtractive are complementary.
