HMT's dual-stack all-electric CNC tube benders couple every axis directly to its gearbox, with no belts or chains.
HMT builds its dual stack all-electric CNC tube benders in Madera, CA, in models from the 2.0ECNC-DS up to the 4.0ECNC-DS. Two tool stacks mount at once, servo motors with smaller gear reductions raise speed, and the belt-free drivetrain improves accuracy and repeatability. Top rated capacity is 4.000 X 0.188 steel tubing.
Built in Madera, CA, the line runs from the 2.0ECNC-DS to the 4.0ECNC-DS.
Each machine mounts two stacks of tools at once, either two rotary draw sets or one rotary draw set with roller tooling. That gives a low-interference layout compared with multi-stack benders, while large servo motors and drives with smaller gear reductions deliver higher speeds.
For the shop floor, the payoff is less maintenance plus better accuracy and repeatability on every axis. At the top of the range, the 4.0ECNC-DS bends 4.000 X 0.188 steel tubing, with stainless, square, pipe and solid bar ratings besides.
Frequently asked questions
What are the advantages of HMT's dual-stack design for CNC tube benders?
The dual-stack design offers a low-interference configuration, making it ideal for complex part shapes. It allows for mounting two sets of rotary draw tooling or one set of rotary draw tooling and one set of roller tooling simultaneously.
What are the specifications for the 2.0ECNC-DS model in terms of tubing and bar capacity?
The 2.0ECNC-DS model can handle non-ferrous tubing up to 2.000 inches (50.8 mm) in diameter, steel tubing up to 2.000 inches (50.8 mm) with a 0.188-inch (4.7 mm) wall, and stainless steel tubing up to 2.000 inches (50.8 mm) with a 0.095-inch (2.4 mm) wall. It also accommodates square steel tubing up to 1.500 inches (38.1 mm) and solid steel bars up to 1.000 inch (25.4 mm) in diameter.
How does the dual-stack design impact the maintenance and accuracy of HMT's CNC tube benders?
The dual-stack design uses large servo motors and drives with smaller gear reductions, increasing speeds. Each axis is directly coupled to the gearbox without belts or chains, reducing maintenance needs and improving accuracy and repeatability.
What are the key differences between the 2.0ECNC-DS and 3.0ECNC-DS models?
The 3.0ECNC-DS model has a larger capacity for non-ferrous tubing (3.000 inches or 76.0 mm), steel tubing (3.000 inches or 76.0 mm with a 0.188-inch or 4.7 mm wall), and stainless steel tubing (3.000 inches or 76.0 mm with a 0.095-inch or 2.4 mm wall) compared to the 2.0ECNC-DS model.
What is the maximum capacity for steel pipe in the 4.0ECNC-DS model?
The 4.0ECNC-DS model can handle steel pipe up to 3 IPS Sch 40.
