Dlaczego warto wybrać automatyczną giętarkę CNC do rur z wąską głowicą do gięcia stelaży krzeseł?

Chair frames are typical 3D tubular workpieces with multiple continuous bends and narrow internal gaps. If you use a conventional tube bender with a thick bending head, the machine head will easily collide with the already bent tube sections during forming. Such mechanical interference forces operators to split the whole frame into separate segments, perform repeated clamping and secondary positioning. This method slows down production, introduces cumulative dimensional errors and raises scrap rates for chair manufacturing.

The thin-head CNC tube bender is specially optimized for furniture chair frame bending. Its slim bending head greatly reduces mechanical interference. It can reach into the confined space of chair frames and complete all 2D and 3D bends in one single tube clamping. No secondary loading or repositioning is needed.

For mass production of office chairs, leisure chairs and metal stool frames, this design brings multiple practical benefits.

First, one-time forming shortens cycle time and improves output capacity. All bends keep consistent geometric dimensions, so welded chair frames fit perfectly in assembly and less corrective grinding is required.

Second, it handles thin-wall carbon steel and galvanized round tubes commonly used for chair skeletons. Equipped with mandrel and anti-wrinkle blocks, it prevents tube wrinkling, flattening and cross-section deformation during bending.

Third, it supports quick program switching and simple die replacement. Furniture factories can rapidly switch between different chair models, suitable for both mass orders and small-batch customized chair frame jobs.

Combined with 3-axis servo control, the thin-head DW38CNC3A1S bender delivers stable precision for long continuous shifts. It is the ideal machine solution for furniture manufacturers focusing on metal chair frame fabrication.
