Estun E21s Controller CNC Metal Sheet Cutting Rolling Shearing Punching Machine

The primary difference lies in the movement of the upper blade holder. In a swing beam shear, the upper holder pivots on a central shaft, moving in an arc . In a guillotine shear, the holder moves in a strict vertical linear path . Our swing beam design offers a robust, cost-effective solution for a wide range of standard shearing applications.

Our machine features a fully welded steel structure, stress-relieved for high strength and rigidity . It utilizes hydraulic transmission for smooth, reliable performance. The upper blade has two cutting edges, and the lower blade has four, effectively doubling the blade life compared to some other designs. The blade gap is easily adjusted via a handwheel for precise control.

The blade gap is critical for a clean, burr-free cut. It should be adjusted based on the type and thickness of the material. Our machine features a simple handle mechanism for quick adjustment. A general rule is to set the gap to approximately 0.05mm for thin sheets and increase it gradually with material thickness. For a 6mm sheet, a gap of around 0.65mm might be suitable. Always consult the machine's manual for the recommended gap settings.

Yes, but you must ensure the material is properly and securely held down by the hydraulic hold-downs (clamping system). Never attempt to cut material that is too narrow to be firmly clamped, as this is a safety hazard and will result in poor cuts.

Rough cuts or burrs are often a sign of one of three issues: 1. Incorrect Blade Gap: The gap between the upper and lower blades may be set too wide for the material thickness. 2. Dull Blades: The cutting edges may be worn and need to be rotated or replaced. 3. Insufficient Clamping Pressure: The material might be moving during the cut.
