Our machining focus.
SYD Precision (Dongguan Shengyuanda Precision Co., Ltd.) is a precision CNC machining factory based in Dongguan, Guangdong, China. We provide custom milling and turning for aluminum and steel components, with a focus on prototypes and small production runs.
We work with engineers and purchasing teams on parts for robotics, automation and industrial equipment. From housings and brackets to shafts and fixtures, each inquiry starts with your drawings, material and intended application.
Our approach is straightforward: clarify the requirements, agree on the manufacturing scope, and keep the drawing revision, finish and inspection needs aligned throughout the project.

OUR MACHINING EQUIPMENT
JF-V1200 Three-Axis Machining Center
Our Jiafu JF-V1200 vertical machining center supports three-axis CNC milling. Its Mitsubishi M80V control and BBT40 spindle support machining operations for custom housings, plates, brackets and fixtures.
| Machine type | 3-axis vertical machining center |
|---|---|
| X / Y / Z axis travel | 1200 × 600 × 600 mm |
| Table size | 1400 × 600 mm |
| Maximum table load | 800 kg |
| Control system | Mitsubishi M80V |
| Spindle taper | BBT40 |
| Maximum spindle speed | 12,000 rpm |
| Maximum spindle power | 11 kW |
Axis travel describes machine movement. The suitable workpiece size depends on geometry, workholding and tool clearance. Send your drawing for a machining review.

Requirements defined before machining
Critical dimensions, geometric features and surface requirements are reviewed against your drawings. Inspection methods and any reporting needs are agreed for the part, rather than assumed from a general tolerance claim.


Working together
A clear path from drawing to delivery
Send your requirements
Provide a 2D drawing or 3D model, material grade, quantity, finish and delivery requirements. Mark critical dimensions.
Agree on the scope
Review manufacturability, pricing, drawing revision and inspection needs before approving production.
Machine, inspect and deliver
Parts are machined and reviewed against the agreed requirements, with packaging and shipping arrangements confirmed for the order.
Real project · 7075 aluminum
See the part, not just the promise.
A five-axis simultaneous machining project with curved profiles, circular openings and mounting features. The photographed parts are as-machined, with no surface treatment.

Before you inquire
Practical answers for your machining project
Does machine travel equal maximum part size?
No. The JF-V1200 has X/Y/Z travel of 1200 × 600 × 600 mm. Suitable workpiece dimensions also depend on geometry, fixtures and tool clearance. Send the drawing for review. View our JF-V1200 equipment and capacity details.
How are tolerances and inspection agreed?
Mark critical dimensions and geometric tolerances on your drawing. We review measurement methods and reporting requirements for the individual part before confirming the scope. Explore our inspection approach.
Can I request prototypes or a small batch?
Yes. Our focus includes prototypes and small production runs. Send the quantity for each part, material grade, finish and required delivery date so we can review your request.
What should I prepare for a quotation?
Send a 2D drawing or 3D model, material, quantity, critical tolerances and surface finish. Include the drawing revision, destination country and required delivery date. Open the quote request checklist.
