All-electric Multi-stack CNC Tube Bender


The most common all-electric CNC tube bender in existence has to be a 3″ OD multi-stack design. Almost every manufacturer that produces CNC tube benders has a design of this type.

When HMT designed its 3.0ECNC-MS model, it had to be extremely fast, capable of running 24/7 and be able to bend 3″ stainless steel on a 3″ CLR. HMT also wanted this bender to be able to hold a minimum of 4 stacks of tooling and have true multi-radius capabilities.

The end result has been pure magic and the 3.0ECNC-MS is by far HMT’s top selling machine. These machines are found throughout the automotive industry, shipyards, HVAC manufacturers, aerospace, and of course in metal fabricators throughout North America.
