General Info:

Volna Engineering Mission For the past forty years, Volna Engineering has provided one-of-a-kind solutions to difficult measurement and tooling problems for the aerospace and defense industries. Significant trademarks of Volna Engineering design embody the principles of "kinematic coupling, " as follows: Any free solid body has six possible degrees of freedom in space -- three of translation and three of rotation. Products of Kinematic Design The following photos of Volna Engineering products are examples of kinematic design that have successfully stood the test of time with undiminished performance: Embodying the principles of "kinematic coupling, " these roll-tumble, two-axis test tables were built for the final calibration testing of Honeywell ring-laser navigation systems and have been in service for 19 years with unchanging sub-arc-second accuracy. The first requirement of this Visual Target Acquisition System ( VTAS ) device is magnetic transparency. Linen phenolic and epoxy are used to fabricate the main frame. The x, y, and z "ways" are optically polished glass, straight within 10 arc-seconds. Kinematically constrained ceramic ball spindles provide arc-second accuracy after 18 years of service.
