At Zeman Manufacturing, CNC tube bending is both a core capability and a competitive advantage. Our advanced equipment supports high-precision assemblies for demanding industries such as medical, aerospace, energy, transportation, and foodservice. Every CNC bender on our floor is fully electric and servo-driven — delivering unmatched consistency, tighter angle accuracy, and smoother transitions across complex geometries.

All-electric bending systems eliminate the inconsistencies associated with hydraulic and hybrid machines. By reducing mechanical backlash and optimizing control on every axis, we’re able to produce parts with minimal angle variation—even in tight-radius, multi-plane configurations. This makes our process ideal for high-spec, small-diameter tubing where repeatability and quality are paramount.

Whether you’re prototyping a new design or scaling to full production, Zeman’s all-electric CNC bending lineup is engineered for control, speed, and reliability.
