SDY-QF1000-Z Heavy-Duty Hydraulic Large-Size Aluminum Alloy Cutting Machine: Built for Larger Cutting Jobs

Standard and small aluminum workpieces are easy to cut — plenty of machines on the market can handle them. But once the size goes up, a conventional profile saw simply cannot do the job. That is where a heavy-duty hydraulic aluminum cutting machine comes in.
Shuangdeyu offers three heavy-duty hydraulic saws — SDY-QF650-Z, SDY-QF800-Z and SDY-QF1000-Z — covering different large-size aluminum cutting requirements. This article focuses on the SDY-QF1000-Z.

1. How large can it cut: 700 mm wide × 370 mm high
The SDY-QF1000-Z cuts up to 700 mm wide and 370 mm high. It runs a Ø1000 mm blade on an 18 kW main motor.
If a customer's workpiece is even larger, a more powerful motor can be specified — there is power to spare.
2. Typical application: aluminum motor housings
Among Shuangdeyu's customer cases, one of the parts this machine cuts most often is the aluminum motor housing.
Large motor housings with irregular cross-sections are exactly the kind of part a conventional profile saw cannot handle — and the reason a heavy-duty hydraulic saw is needed.
3. Key features
- Patented worktable structure that protects the material surface
- Servo motors drive feeding, sawing feed and remnant handling — fast, stable and reliable
- Automatic positioning, automatic lubrication, automatic sawing, automatic blade splitting and automatic remnant handling for easy operation
- Programmed safety door interlock for safer operation
- Imported-brand ball screws and linear guides for stable sawing
- Spindle accuracy controlled within 0.005 mm, matched with ultra-thin alloy blades to cut material waste; blades can be resharpened repeatedly to lower operating costs
