Product Details

7-Axis, 2-Channel Swiss-Type Machining

The SL327 is equipped with a Taiwan Syntec control system and 7-axis, 2-channel control. It is designed for efficient machining of small and complex precision components.

Guide-Bushing and Guide-Bushingless Modes

The machine supports both guide-bushing and guide-bushingless configurations. Maximum machining length is 310 mm in guide-bushing mode. In guide-bushingless mode, the maximum length is 2.5D, up to 80 mm.

Live Tooling and Back-Working

The gang-tool layout supports turning, drilling, grooving, threading, tapping and live-tool machining. A back spindle supports rear-end machining. The B-axis angle ranges from 0° to 135°.

Rigid Structure and Precision Feed

The machine uses a high-quality Meehanite cast-iron bed and slide structure. The specified spindle runout is no more than 0.002 mm, and repeat positioning accuracy is no more than 0.003 mm.

Automation Options

An automatic bar feeder is available for continuous bar-fed production. Tooling and automation options can be configured according to the part drawing, material and production requirements.

Typical Applications

Suitable for precision components used in communications, electronics, automotive, pneumatic and hydraulic systems, medical devices, instruments and aerospace.

Machine manufacturer: Ningbo Yongbo Machinery Manufacturing Co., Ltd.

Supplied and supported by: SIPENG CNC, Tianjin, China.

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.
