Serpentine tube bender used to make coils for heat transfer application. Imported from a STEP file into the benders controller, the CNC bender bends up the tubing from a bulk spool. Auto feed, bend, cut and unload. Lights out manufacturing.
The SB series CNC serpentine tube benders are designed for high speed production use. All SB models tube benders provide for serpentine tube bending without the need to rotate the material between bends (R axis plane rotation).
Program the bend angles, centerline radius, straight lengths, and serpentine production begins. The tubing always stays in contact with the support table maintaining flatness. One of the advantages of the SB series type tube bender is its ability to manage the serpentine coil as it is being formed. Because the bend head can bend both CW and then CCW without rotating the tube between bends, the ability to control larger serpentine coils becomes much easier.
Bending serpentine profiles—successive 180-degree bends, which typically are used in refrigeration systems—can be a challenge. By their nature, they tend to cause interference among the various bend dies, and they can be difficult to handle. Good planning in selecting a bender, planning the process, and paying close attention to infeed and outfeed options, can help make a serpentine project successful.
