Product Overview
The PD20II, PDJ20II, PD30II and PDJ30II are compact CNC turning centers for efficient machining of small precision components. The PD20II / PDJ20II models support bar stock up to Ø20 mm, while the PD30II / PDJ30II models support bar stock up to Ø30 mm.
Key Features
- Built-in electric spindle with imported ultra-precision angular-contact ball bearings.
- Specified spindle runout of ≤0.002 mm.
- Meehanite cast-iron bed and slides provide a rigid machine structure.
- Dovetail tool-post layout supports quick, accurate tool changes.
- Servo-driven feed axes with imported precision screw bearings and guideways.
- FANUC CNC is standard on PD20II / PD30II; Taiwan Syntec CNC is standard on PDJ20II / PDJ30II.
- Optional bar feeder or custom automatic loading and unloading robot is available.
Applications
Suitable for evaluating small precision components for communications, electronics, automotive, pneumatic and hydraulic equipment, medical devices, instrumentation and aerospace applications. Confirm process suitability against the part drawing, material, tolerances and production requirements.
Model selection: Choose PD20II / PDJ20II for Ø20 mm bar capacity or PD30II / PDJ30II for Ø30 mm bar capacity. Control type and repeat positioning accuracy vary by model.

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.
