Product Details

Product Overview

The SL325, SL326, SL385 and SL386 are Swiss-type CNC turning centers designed for complex, small-diameter and slender precision components. Select the Ø32 mm SL325 / SL326 models or the Ø38 mm SL385 / SL386 models according to the workpiece and process requirements.

Key Features

Radial live tooling and spindle indexing support combined turning, milling and drilling.
Guide-bushing configurations provide flexibility for different part lengths and machining processes.
Standard Taiwan Syntec dual-channel CNC control; FANUC or Mitsubishi controls are available as options.
High-rigidity Meehanite cast-iron bed and slides.
Imported angular-contact spindle bearings, servo feed axes, precision screw and guideway components, and roller guides at key positions.
Optional bar feeder supports continuous production.

Applications

Designed for evaluating and machining complex, small-diameter precision parts and slender shafts for communications, electronics, automotive, pneumatic and hydraulic equipment, medical devices, instrumentation and aerospace applications. Confirm suitability against the part drawing, material, tolerances and production plan.

Configuration note: Tooling, live-tool stations and some machining functions differ by model. Optional items and final specifications should be confirmed for the selected machine configuration before ordering.

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.
