Common Questions & Answers

Q1: Is burr removal always necessary?
Not always. For light-wall or general-purpose tubing, internal deburring may not be required. However, it's recommended for structural or high-spec applications.

Q2: How long does the knife last?
The knife is a consumable. HSS or carbide blades typically last 1–3 weeks depending on speed, material, and maintenance. Keep spare sets available for continuous operation.

Q3: Does the knife require precise weld alignment?
Yes. Poorly aligned or inconsistent welds can cause blade deflection or breakage. Weld quality should be stable before applying internal burr removal.

Q4: Is the knife easy to replace?
Yes. Most knife holders are designed for quick change, with replacement typically taking just a few minutes.

Usage Tips

• Always align the knife precisely with the weld seam before operation.

• For automated lines, use seam-tracking systems to optimize blade positioning.

• If scratching or tube wall damage occurs, inspect blade sharpness and angle settings.

• When changing tube diameters, use matching knife heads or inserts for best results.
