A standard machine covers the market. It does not cover your profile.
Standard cutting machines handle the mainstream range. They stop being enough the moment the profile itself is wide, or the job needs a full row of material loaded and cut in one pass. That is where a stock machine runs out of stroke, and where a trader has nothing left to offer. We build the machine instead.
Shuangdeyu Precision Machinery (Suzhou) Co., Ltd. is a manufacturer. When a standard platform cannot reach the number, we change the structure, not the datasheet.
The case behind this model
A recent customer came to us after searching the market for a machine that did not exist off the shelf. He cuts welded aluminum tube, and he needed one thing above all: a sawing stroke of 600 mm. With that stroke, a full row of raw material can be loaded at once. On a single wide profile, anything less than 600 mm simply will not cut through.
The standard SDY-QFW500-B.7 cuts to a width of 400 mm. That leaves 200 mm short of the requirement, and 200 mm is not a number you can negotiate with a machine. We built him a custom model, SDY-QFW500-B.7-6560, with a 6,500 mm servo feeding stroke, a 7-meter guide rail held within 0.01 mm, and a 15.6-inch extra-large touch screen.
Long stock is what this machine is made for. It feeds far, cuts fast, and holds accuracy while doing it.

On site: 17 tubes in one pass
The photo above is from the actual cutting floor, not a studio. 38 mm aluminum tube, laid crosswise, 17 pieces cut in a single pass.
The same machine handles wider aluminum profiles. And if your material asks for more than this, more feeding stroke, more cutting width, more pieces side by side, we keep modifying. That is the difference between buying a model and commissioning a machine.
FAQ
What does the 600 mm sawing stroke actually change? It sets how much material the saw can pass through in one cross cut. A standard SDY-QFW500-B.7 is rated at 400 mm of cutting width. At 600 mm of stroke, a full row of tubes or a single wide profile clears the blade in one pass instead of being split into two operations.
How long a bar can it feed automatically? The servo feeding stroke is 6,500 mm, with an automatic feeding length range of 10 to 6,500 mm and a reciprocating cycle mode for longer stock.
How is accuracy held over that length? The machine runs on a 7-meter guide rail held within 0.01 mm, with 0.005 mm spindle accuracy. Cutting flatness and squareness are both 0.05 mm, and feeding accuracy is ±0.1 mm within 1 m.
Can the machine be widened or lengthened further? Yes. Cutting stroke, feeding stroke and side-by-side capacity are all structural decisions, and they can be reworked on this platform. Send the section drawing and the cut length you need.
Are you a manufacturer or a trading company? A manufacturer. The machine is designed and built in house by Shuangdeyu Precision Machinery (Suzhou) Co., Ltd., which is why a 200 mm shortfall becomes a new model instead of a polite refusal.
