会社のニュース How to Avoid Burrs and Camber When Slitting High Tensile Spring Steel Sheets?

High tensile spring steel sheets are widely used in automotive parts, mechanical springs, and tool manufacturing due to their excellent elasticity and hardness. However, with tensile strength reaching up to 1000 MPa, slitting often results in large burrs, poor accuracy, and severe camber, which can negatively impact subsequent processing and final product performance.

To address these challenges, the High Tensile Sheet Coil Slitting Machine incorporates several technical enhancements:

1. High-hardness knives: Alloy steel blades with hardness up to HRC60-61 ensure sharp cutting edges and long service life.

2. Strong tension control: A combined roller and felt tension unit stabilizes the strip during high-speed operations, preventing camber.

3. Deep accumulator pit: Ensures smooth strip transition during high-speed slitting, reducing stress concentration.

4. High-precision guiding system: Guarantees consistent strip widths and overall product quality.

In practice, heavy-duty high-speed slitting lines control burrs within 5% of strip thickness and keep camber below 0.5mm. For customers who prioritize quality and stability, this solution significantly reduces rework rates, minimizes material waste, and lowers production costs.
