Innovative Polishing Systems/Mitutoyo Scratch Gage

Innovative Polishing Systems and Mitutoyo develop scratch gage

Mitutoyo America and Innovative Polishing Systems, Inc., Stuart, Florida, recently collaborated on development of an instrument capable of accurately and easily measuring the depth of scratches in glass. Innovative Polishing Systems’ business is to polish-out scratches in the repair of high-value glass typically found in architectural, auto, marine and aerospace applications. If the glass cannot be restored, it must be discarded. Polishing is feasible only if the scratch is not too deep, generally no more than 0.002”. So having good data on scratch depth is critical in determining the course of remedial action. As a result, Innovative Polishing Systems decided it would be beneficial to replace traditional, imprecise “manual” methods of determining scratch depth (feeling with a finger nail, or by visual comparison of the damage to...

Space Metal Fabricators/Mitutoyo Helicopter Blade Adjuster

Space Metal Fabricators and Mitutoyo America Collaborate on helicopter blade adjustment tool

Space Metal Fabricators of Columbia, South Carolina, and Mitutoyo America Corporation have jointly developed a tool to help helicopters fly smoother. While flying, helicopters generally experience a low frequency vibration in the main rotor blades. This is due, in part, to slight differences in each blade’s aerodynamics. These vibrations are not likely to cause structural damage but may adversely affect electronics; they also absorb power. To dampen vibration, some main rotors incorporate trim tabs located on the blades’ trailing edges which can be adjusted to keep blades rotating smoothly. Some systems incorporate electronic, in-flight rotor track-and-balance systems that provide information used to adjust the pitch of the tabs. Specialized tools then are used to physically bend the tabs. Besides in-flight indication, tab adjustment may result...
