New Ultra-Low Frequency Vibration Isolation Workstation

March 13, 2007
Minus K Technology, Inc. ( ), in a joint venture with Kinetic Systems, has released the MK26 Series Vibration Control Workstation™, specifically designed for ultra-low natural frequency applications and negative stiffness vibration isolators, to provide a compact, passive vibration isolation workstation, with excellent vertical and horizontal isolation efficiencies. Based on field testing and user evaluations, the Minus K 1/2-Hz vibration isolation workstation performs about 10 to 100 times better than high-performance air tables, depending on vibration isolation frequencies, and better than active or electronic-cancellation systems. The MK26 Series can be configured for a wide variety of applications and customized with a broad range of vibration isolation workstation accessories. Minus K negative stiffness vibration isolators employ a revolutionary concept in low-frequency vibration isolation. Vertical-motion isolation is provided by a stiff spring that supports a weight load, combined with a negative-stiffness mechanism (NSM). The net vertical stiffness is made very low without affecting the static load-supporting capability of the spring. Beam-columns connected in series with the vertical-motion isolator provide horizontal-motion isolation. The horizontal stiffness of the beam-columns is reduced by the "beam-column" effect. (A beam-column behaves as a spring combined with an NSM.) The result is a compact passive isolator capable of very low vertical and horizontal natural frequencies and very high internal structural frequencies. Minus K isolators (adjusted to 1/2 Hz) achieve 93% isolation efficiency at 2 Hz; 99% at 5 Hz; and 99.7% at 10 Hz. Unique features of the MK26 Series Vibration Control Workstation include: •Ultra-Low Natural Frequencies •Vibradamped Frame •Customizable Accessories •No Air Supply or Electric Power Needed - Easy to Use •Choice of Tabletops •Ergonomic Styling •Class 100 Clean Room Compatible •Class 10 Available •No Maintenance The MK26 provides for easy adjustment: The Vertical Load Adjustment Crank is a simple manual adjustment which compensates for changes in vertical load; the Vertical Load Adjustment Indicator lets you easily determine the optimum setting using this simple visual indicator; and the Vertical Stiffness Adjustment screw lets you easily dial in a guaranteed * Hz or less vertical natural frequency. The unit has a maximum load capacity of 700 lbs., a maximum tabletop width of 48”, and maximum tabletop depth of 36”. • Ultra-Low Natural Frequencies • Vibradamped Frame • Customizable Accessories • No Air Supply Electric Power Need – Easy to Use • Choice of Tabletops • Ergonomic Styling • Class 100 Clean Room Compatible • Class 10 Available • No Maintenance
