Feed, turn and bend
The DW CNC source describes programmable bending with servo-controlled tube turning and feeding. Confirm the selected model’s complete motion package and sequence.
A multi-plane workpiece needs more than a bend-angle list. Send straight lengths, rotation planes and the complete finished geometry, including the positions that are difficult to clamp or support.

The source lists bending precision ±0.1° for most rows and ±0.2° for DW-219CNC, DW-273CNC and DW-325CNC. These and feed/turn figures do not establish unconditional whole-part tolerance. Agree test conditions and actual finished-part acceptance.
Keep the common configuration reference
The source describes servo bending on applicable configurations and hydraulic bending for larger configurations. CNC control alone does not prove all-electric bending, a particular axis count or every tool on the supply list.
Feeding length, radius and speed are separate limits
Usable feed arrangement
Review the listed feed length with tube loading, clamping and the chosen direct or indirect feed mode. Confirm the complete workpiece reach.
Radius and tooling
A listed maximum radius does not define the minimum bend radius. Obtain the actual die and support-tool review.
Completed-part cycle
The table gives separate maximum feed, turn and bending speeds. Do not combine them into a guaranteed parts-per-hour figure.
Questions to settle before ordering
Are 33 bends and 50,000 programs standard?
They are industrial-computer-type references. Confirm the controller package; the PLC references differ.
Are the DW-58CNC and DW-50CNC size labels consistent?
Their source OD entries appear mismatched with their names. Obtain model-specific confirmation rather than silently changing the table.
Is every CNC machine all-electric?
No. The source describes both servo and hydraulic bending configurations.
Does ±0.1° guarantee every finished part dimension?
No. Whole-part acceptance depends on the actual stock, tooling, setup and sequence.
What is needed for a CNC production trial?
Full geometry, grade, OD, wall, radius, rotation sequence, critical dimensions and the batch mix.
