 Size thickness 6mm length 2500mm

The 6mm thickness and 2500mm length capacity represents the exact core capability of the QC12Y-6×2500 Hydraulic Swing Beam Shearing Machine shown in your second nameplate photo.

Here is a targeted technical guide on how this specific machine handles 6mm × 2500mm iron/mild steel sheet cutting, along with essential operational rules for this capacity:

1. Material Capacity Breakdown

While the machine is rated for a maximum of 6mm, that thickness limit depends entirely on the tensile strength of the metal you are cutting:

• Mild Steel / Iron Sheets: Full 6mm maximum capacity.

• Stainless Steel: Maximum 3mm (Stainless steel is much harder; trying to cut 6mm stainless will overload the hydraulics and damage the blades).

• Aluminum / Soft Alloys: Up to 8mm can typically be cut safely.

2. Crucial Step: Adjusting Blade Clearance (Gap Setting)

To get a clean, straight cut on a 6mm sheet without producing massive burrs or jamming the machine, you must manually adjust the Blade Clearance Handwheel on the side of the frame

3. Best Practices for Cutting Full-Length (2500mm) Sheets

• Verify the Hold-Down Plungers: Because you are shearing across a full 2500mm (8.2 feet), the sheet will want to twist or kick upward. Ensure all 13 hydraulic hold-down plungers drop down firmly onto the sheet before the blade starts moving down.

• Never Exceed the Rake Angle: The fixed rake angle ($1^ 30'$) is optimized to reduce twisting on a 6mm plate. Let the machine cycle at its natural stroke rate (approx. 14–18 cuts per minute)—never try to force or rush the material through.

• Keep Blades Flipped: If you notice the 6mm iron sheets are leaving rough, rolled edges, do not rush to grind the blades. Remember that both the top and bottom blades have 4 sharp cutting edges. You can unbolt them, rotate them to a fresh face, and bolt them back down.
