The features include the standard equipped W spindle units and 3D (XYZ) movement of the manufacturing units. The structures work well for springs with multi bending R or necessary to be widely swung during automatic operation. The unit back-and-forth movement also works well for coiling in terms of rigidity and diameter adjustment.

Unlike compression springs and extension springs, there are a wide variety of shapes in torsion springs. In other words, there is no perfect torsion machine for every torsion spring. Isn’t it important to understand and utilize the characteristics of each model in preparation for the various spring characteristics?

It is easy to come up with ways to increase the processing speed. There are two stages in setup for torsion spring: 1) creating the shape, and 2) improving the production speed. Torsion springs require more processes than compression or extension springs, so in step 2, it is important to reduce waste between each process. Our motion chart function allows programming data to be visualized, making it easy to correct the programming data such as eliminating waste.

The NFA series has three manufacturing units, compared to the two in the NF series, which bring more versatile and faster machine performance. In addition to one unit processing, the NFA structure makes combination process with the upper and left/right units possible for better versatility. The series has NFA60 for 6mm (.236″) wire and NFA80 for 8mm (.314″) wire, which also becomes a major feature.

There are 15 standard spindle tools which can make most of the patterns. Special tools can realize difficult shaped torsion springs with faster production speed.
