All-Electric Single-Stack CNC Tube Bender



HMT manufactures a full line of single stack all electric CNC tube benders. These benders are easily configured to include a variety of options including extended bed lengths, and a variety of automatic mandrel lubrication systems.

When HMT designed its 3.5ECNC-SS model, the same criteria needed to be met as our multi-stack machines. The frame must have HMT’s uni-body design, be extremely fast and capable of running around the clock. The jump to a 3.5″ design from a 3.0″ design may not seem like a big leap, but HMT doesn’t take short-cuts in design. The pressure die system and clamp system had to be able to accommodate the larger forces that are required when bending 3.5″ OD stainless steel on a 3.5″ radius. This machine has automatic setup capabilities and tool changes are still very fast, although the tools get a bit heavier.
