Product Details

The S205, S206, S265 and S266 are Swiss-type CNC turning centers for precision machining of small-diameter and slender components from bar stock.

The S205 and S206 support bar stock up to Ø20 mm. The S265 and S266 support bar stock up to Ø26 mm. Maximum machining length depends on the guide-bushing configuration: up to 2.5D, with a maximum of 50 mm, in guide-bushing-free operation; 220 mm with a fixed guide bushing, available as an option; and 180 mm with a rotating guide bushing.

The machines support main-spindle and back-spindle machining. Radial live tooling and main-spindle indexing allow turning, milling, drilling and tapping operations to be combined. A bar feeder is available for continuous production.

A dual-channel Taiwan Syntec CNC system is standard. FANUC and Mitsubishi controls are available as options. The machine uses a high-rigidity Meehanite cast-iron bed and precision feed components.

Stated performance values include main-spindle runout of ≤0.002 mm and repeat positioning accuracy of ≤0.003 mm. Available tooling and options differ by model. Please confirm the final configuration against the selected model and part requirements.

Frequently Asked Questions

I can provide drawings, material and blank specifications. Can you recommend the right machine and machining route?

Yes — that is exactly how we start. Send the drawing (PDF, DWG or STEP), material grade, blank dimensions, key tolerances and your target output. Our engineers review the part geometry and process, then recommend a machine model, fixture concept and machining route, together with an estimated cycle time. We reply with a written evaluation and quotation within 24 hours.

Can my part be completed in one setup? Which operations would need other equipment?

It depends on geometry, size and accuracy, so we answer this per part, not in general. After reviewing your drawing we reply in writing: which operations are completed in one clamping, which need a second operation or a different machine, and what the recommended process chain looks like. If a part genuinely needs two setups, we say so instead of promising one-setup results.

Are cutting tools, fixtures, bar feeder and CNC programs included?

They can all be included — the delivery scope is defined line by line in our quotation. A typical turnkey package covers the machine, fixtures designed for your parts, the tooling package, bar feeder integration and CAM programs for your parts, plus a recommended consumables list. If you prefer machine only, or want to keep your existing tooling, the scope is adjusted and every included and excluded item is listed before you sign.

How do you evaluate the machining time for my parts?

We build the process route first, then calculate cycle time from tool paths and cutting data, and cross-check it with CAM simulation. The estimated time per part is stated in the proposal. During trial cutting the actual cycle time is measured; the measured result — not the paper estimate — is the basis for acceptance, so the number you plan production around is a verified one.

Can you run trial cutting with my own material?

Yes, and we recommend it. You send material or blanks; after the machine, fixtures and programs are ready we machine your parts, record cutting parameters, cycle time and tool behaviour, and provide a trial report with measurement results, photos and video. The trial schedule is agreed with you in advance, so you can attend in person or follow it remotely.
