Product Details

The SL Series includes the CSL1203II, SL203 and SL263 Swiss-type CNC turning centers for precision machining of long, slender and intricate bar-stock components.

Maximum bar capacity is Ø12 mm for the CSL1203II, Ø20 mm for the SL203 and Ø26 mm for the SL263. Available machining length depends on the model and guide-bushing configuration. Guide-bushing and guide-bushing-free configurations are available for process matching.

Radial live tooling and main-spindle indexing support combined turning, milling and drilling operations. The machines can be integrated with an automatic bar feeder for continuous production.

A 3-axis Taiwan Syntec CNC system is standard. FANUC and Mitsubishi controls are available on request. The machine structure uses a one-piece Meehanite cast-iron bed and slides, precision ball screws, linear guides and high-precision spindle bearings.

Tooling, live-tool options and machining capacity vary by model. Please confirm the selected model and final configuration against the part drawing and process 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.
