Overview
SK-38 Multi-tasking Swiss-Type Turning Center
SK-38 combines a high-rigidity gantry-type tool system with turning, milling, drilling and tapping capabilities. The structure provides stable support for demanding production cycles, while different tooling configurations accommodate components with multiple machined features.
The hybrid guide bush system allows operation with or without the guide bush. Machining capacity is Ø38 mm × 320 mm per chucking in guide bush mode and Ø42 mm × 95 mm in bushless mode. The built-in main spindle reaches 7,000 rpm, with 7.5 kW continuous output and 11 kW for 10 minutes.
The SK-38B configuration adds a B-axis tooling system with a 135° angular range and 0.001° minimum indexing increment. It supports angled drilling and simultaneous 4-axis contour milling. The Y2 axis, included in SK-38Y and SK-38B, provides 69 mm travel for off-center machining on the rear of the workpiece.
Sub-spindle versions support workpiece transfer and, when equipped with a backworking tooling system, rear-end machining. C-axis control with 0.001° resolution supports live-tool operations and cylindrical or polar coordinate interpolation. The standard Air Bag function helps limit the consequences of accidental collisions, while optional OCR Oscillation Cutting improves chip control.
Key Features – SK-38 Series

Notes
- Guide bush mode supports Ø38 mm machining diameter and 320 mm turning length per chucking. Bushless mode supports Ø42 mm and 95 mm respectively.
- The sub-spindle is included in C, D, Y and B configurations. Y2-axis control with 69 mm total travel is included in Y and B; B-axis control is included in B.
- The basic tooling layout and B-axis tooling layout represent different configurations. The B-axis system combines two ER20 cross live tools with three front and three rear ER16 B-axis live tools.
- The Ø42 mm capacity applies to bushless machining. The specified backworking chucking diameter is Ø38 mm, with a maximum part length of 150 mm for front ejection.
- Continuous and 10-minute motor ratings refer to different duty conditions. Main-spindle, sub-spindle and live-tooling drive powers are specified separately.
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.
Energy
Pump and valve components, compressor parts, and auxiliary housings; controlled cutting and chip/coolant management help protect tolerances, surface finish, and tool life.
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.
