SW-Ⅱ Series
SW-Ⅱ is a family of Swiss-type CNC turning centers for precision production, with Ø20 mm capacity on SW-20Ⅱ and Ø32 mm on SW-32Ⅱ. Hybrid guide bush operation and configurable live tooling support a range of parts, while sub-spindle and backworking versions extend the process to rear-end features.
- Ø20 mm and Ø32 mm machining capacities across the two models
- Guide bush or bushless operation to suit the workpiece
- Optional Y2 backworking with capacity for eight live tools

Overview
SW-Ⅱ Swiss-Type Turning Centers — SW-20Ⅱ / SW-32Ⅱ
SW-Ⅱ combines a rigid machine structure with tooling for turning, milling, drilling and tapping. The family supports series production of small and medium-diameter components, with configurations covering front machining, workpiece transfer and dedicated rear-end operations.
The hybrid guide bush system allows the operating mode to be selected for the part. SW-20Ⅱ provides 220 mm turning length per chucking with the guide bush or 50 mm without it. The corresponding lengths for SW-32Ⅱ are 315 mm and 85 mm.
Main-spindle speeds reach 10,000 rpm on SW-20Ⅱ and 7,000 rpm on SW-32Ⅱ. The C, D and Y configurations include a sub-spindle, while D and Y also provide a backworking tooling system. For versions with a sub-spindle, a built-in motor is standard on SW-32Ⅱ and optional on SW-20Ⅱ.
The tooling system accommodates six external turning tools and 5–10 cross live tools. Special holders support operations such as hobbing, slotting and thread whirling, and the sub-spindle body can be equipped with two deep-hole drills. Optional Y2 control enables off-center rear machining. The standard Air Bag function helps limit damage in the event of a collision, and optional OCR Oscillation Cutting improves chip control.
Key Features – SW-Ⅱ Series

Notes
- Turning lengths apply to a single chucking and depend on guide bush or bushless operation.
- The A, C, D and Y configurations define the presence of a sub-spindle, backworking tooling and Y2-axis control. Sub-spindle specifications apply to C, D and Y versions.
- The built-in sub-spindle is optional for SW-20Ⅱ and standard for SW-32Ⅱ versions equipped with a sub-spindle.
- The basic backworking system provides four tools. The optional Y2 system provides capacity for eight live tools and total Y2 travel of 60 mm on SW-20Ⅱ or 80 mm on SW-32Ⅱ.
- Tool capacity depends on the selected holders and tooling system. Continuous and 15-minute motor outputs describe different operating conditions.
Applications
General machining
Mixed prototype and production work across sizes; flexible envelopes and quick changeovers speed setups, reduce handling, and keep output consistent day to day.
Automotive
Tooling and production parts across the supply chain, from fixtures and dies to turned and milled components; repeatable referencing supports surface quality and tight tolerances.
Aeronautics
Precision structural parts, fixtures, and machined assemblies; probing and process control (where available) help keep flatness and bores in tolerance on long cycles.
Defense
Housings, carriers, and structural parts in high-strength alloys; stable machining conditions and verified datums deliver repeatable accuracy under heavy cuts.
