Marposs Corp. will show its new NanoUnimar ultra-compact gauge head for in-process grinder control in Booth #3006 at the EASTEC APEX 2007. The new gauge is designed to suit the trend for smaller grinding machines. According to the company’s press release, its sub-micron accuracy and stability are, with its compact size, the main features in providing a gauge solution when space is restricted and micro components such as fuel injectors, microbearings and other miniature parts are being ground. The NanoUnimar gauge is designed for measuring external and internal diameters, positioning and length for both smooth and interrupted surfaces. The NanoUnimar gauge has a measurement range of -100 to 300 mm (-0.004-0.012") for in-process measurement applications without mechanical refitting. The gauge has repeatability of 0.1 mm (0.000004"). As two gauge heads, each with a separate measuring finger, are applied for measuring a diameter, the NanoUnimar gauge can be adapted for measuring parts ranging from less than 1mm to approximately 6 mm (0.04-0.2") diameter. The NanoUnimar gauge is also suitable for use with larger parts where numerous measurements must be packed into a confined area. The NanoUnimar gauge head has adjustably retractable fingers with up to 700 mm (0.026")of travel. Measuring applications using the NanoUnimar gauge can be simplified because it is unnecessary to provide devices to move the gauge out of the way to load and unload parts. Mechanical adjustments to the NanoUnimar gauge are accessed externally from above the gauge. The NanoUnimar gauge features IP67 protection against coolant and abrasive substances.
