There is a need for good quality helices in NZ, that cannot be compromised. Many flight manufacturing companies struggle to get good quality which results in a poor product and diminished service life of equipment. Our machine forms true form helices, which means:

1. Accurate fit to shaft for efficient handling
2.    Uniformity for weld procedure
       a)    Pitch angle - If pitch angle is not a uniform linear spiral, welding will require a variety of tracking adjustments to follow the non linear spiral
       b)    Helix flange perpendicular to shaft - a typical incorrect helix usually causes a variety of weld angles around the helix. This will affect both the positional requirements of the weld, and consistency of both throat and root of welding between helix and shaft
3.    Helix internal edge parallel to shaft - the potential variability in the gap between the shaft and the edge of the inner helix edge. If not parallel, can result in a significant variation in the weld root and hence consistency and quality of weld
4.    Therefore - A true pitch helix shall have;
        a)    The flange perpendicular to the shaft
        b)    Uniform pitch angle
