Bellow Trimming/Tangent cutting Machine

Bellow End Trimming Machine, also known as the Tangent Cutting SPM, is a precision machine designed to cut and trim the ends of metallic bellows with clean, burr-free, and perfectly tangent edges. This process is essential to ensure accurate length, concentricity, and proper fitment for welding or assembly of automotive exhaust bellows, EGR tubes, and expansion joints. The machine ensures uniform cutting regardless of convolution depth or bellow material, and is built to withstand continuous industrial operation.

Features

• Precise end trimming of stainless steel and alloy bellows • Ensures tangent, clean, and burr-free cuts for accurate welding • Adjustable holding system to center bellows of various sizes • Suitable for SS304, SS316, SS321, Inconel, and more • Rigid clamping system prevents deformation during cutting • Available with manual, pneumatic, or servo-driven cutting blade • Quick-change fixtures for various bellow diameters and lengths • Compact, low-maintenance design ideal for production lines • Optional digital counter for length preset and repeat cuts
