SDY-QFW550-B No-Remnant Aluminum Profile Cutting Machine
[Intro Paragraph]
The SDY-QFW550-B is a full automatic CNC aluminum profile cutting machine built for factories that cut copper and aluminum in volume. It pairs a no-remnant feeding design with a dual separation sawing system, so each bar is used down to less than 1 mm of waste while the cut face holds ±0.1 mm accuracy.
The machine cuts aluminum profiles, copper profiles, special-shaped profiles, aluminum bars, aluminum tubes, square bars and square tubes — solid or hollow — within a cutting range of 400 mm width × 170 mm height. That range covers the majority of copper and aluminum stock sizes used in the industry, which is why the SDY-QFW550-B is one of our most frequently shipped models.
Why the SDY-QFW550-B Is One of Our Best-Selling Models
No-remnant configuration with a dual separation system. The machine ships with the full configuration in one step, and the dual separation sawing system delivers precise cuts without extra add-ons.
400 × 170 mm cutting range. The machine handles copper and aluminum profiles within a 400 × 170 mm envelope, which means it can cut roughly 80% of the material sizes used in the industry — large stock and small parts on the same machine.
Key Features of the SDY-QFW550-B
1. No-remnant cutting, less than 1 mm remnant. The remnant left after cutting is under 1 mm — less than a single finished part. With CNC automatic feeding, the machine delivers genuine no-remnant cutting on aluminum profiles.
2. Dual separation tool-retraction system. The dual separation design makes sawing more stable and more precise, holding cutting accuracy within ±0.1 mm.
3. 400 mm cutting width, 170 mm cutting height. Maximum cutting height is 170 mm and maximum cutting width is 400 mm, covering most aluminum stock sizes on the market. The machine cuts large stock and small parts alike, and handles a wide range of different materials.
4. Fully enclosed design for noise and dust. The fully enclosed enclosure reduces noise and dust, gives the machine high protection, and keeps maintenance costs low.
5. Single feeding length up to 850 / 1200 mm. Feeding can run in cyclic reciprocating mode, covering both small parts and profiles up to 1200 mm.
6. Optional ultra-thin saw blade. For special requirements the machine can be fitted with an ultra-thin saw blade to save material and reduce cutting cost.
7. Patented worktable structure. The worktable uses a patented structural design that protects the surface of the material being cut.
8. Servo-driven feeding, saw feeding and remnant handling. Servo motors drive the feeding, the saw feed and the remnant handling for fast, stable and reliable operation.
9. Fully automatic cycle. The machine performs automatic positioning, automatic lubrication, automatic sawing, automatic tool separation and automatic remnant disposal, which keeps operation simple.
10. Safety door interlock. The machine program includes a safety door interlock function for safer operation.
11. Imported ball screws and guide rails. Ball screws and guide rails are imported branded components, ensuring stable sawing performance.
12. Spindle accuracy within 0.005 mm. Spindle accuracy is controlled within 0.005 mm, which suits ultra-thin alloy saw blades. The blades can be resharpened and reused, reducing consumable cost for the factory.

FAQ
What is a no-remnant aluminum profile cutting machine? A no-remnant cutting machine is designed to use nearly the whole bar. On the SDY-QFW550-B the material left after the last cut is less than 1 mm, which is less than a single finished part, so almost no material is scrapped as a clamping remnant.
What is the cutting accuracy of the SDY-QFW550-B? Cutting accuracy is ±0.1 mm, achieved with the dual separation tool-retraction system. Spindle accuracy is controlled within 0.005 mm, which supports the use of ultra-thin alloy saw blades.
What is the maximum size the machine can cut? Maximum cutting width is 400 mm and maximum cutting height is 170 mm, covering approximately 80% of the copper and aluminum stock sizes used in the industry.
What is the maximum feeding length? Single feeding length reaches 850 / 1200 mm, and the machine supports cyclic reciprocating feeding, so longer profiles and short parts can both be cut.
Can the machine cut both aluminum and copper? Yes. The SDY-QFW550-B cuts copper and aluminum, including profiles, special-shaped sections, bars, tubes, square bars, square tubes, and solid or hollow material.
Does the machine require much maintenance? The fully enclosed design reduces dust ingress, which lowers maintenance requirements and protects the sawing components.
Do you build custom automatic sawing lines? Yes. We design automatic sawing production lines, robotic laser cutting systems and 3D multi-angle CNC equipment, including machines for automotive bumpers, crash boxes and die-cast aluminum parts.
