The <strong data-start="2311" data-end="2331">BURCH KLB Series</strong> delivers precision internal grinding for small and long vessels. With adjustable pressure, compact design, and high-torque motors (up to 7.5 kW), the KLB 250 and KLB 400 ensure consistent surface finishing and weld blending in confined spaces — ideal for sanitary and industrial vessel fabrication. <p data-start="1486" data-end="1513"><strong data-start="1486" data-end="1511">Applications include:</strong></p> <ul> <li data-start="1516" data-end="1587">Internal polishing and weld seam blending of small to mid-sized tanks</li> <li data-start="1590" data-end="1637">Cleaning and finishing of sanitary containers</li> <li data-start="1640" data-end="1708">Surface refinement for corrosion resistance or coating preparation</li> </ul>

<p data-start="118" data-end="425">High-speed vertical grinding inside vessels for flawless weld seams. Processes 1.5 m seams in ~5 minutes with adjustable speed and robust grinding heads for sheet thicknesses 1–12 mm.</p>

<p data-start="118" data-end="425">The Multi-Purpose Grinding Head Type WLS for smoothing bell-shaped root welds. The machine features adjustable grinding pressure (0–1000 N), a powerful 11–18.5 kW motor, large 300 mm contact wheels, and built-in axial movement compensation for consistent, high-quality results every time.</p>

A weld seam smoothing machine flattens seams by pressing rather than grinding, compacting the structure without heat or dust. No material is removed, ensuring a clean, uniform finish. Optional polishing heads can be added for enhanced visual quality.
