MarVision OMS Product Line Maximum precision and large measuring volumes The OMS product line combines universal multisensor technology and large measuring volumes with maximum precision. This is achieved thanks to the solid fine-grained granite bridge-type design with air bearing axes. These features make the OMS a reference machine in your measurement laboratory. The various machines in the product line have different measuring volumes. All the systems are available with two different levels of precision. Description With its optical sensor laser touch probe systems and state-of-the-art test procedures this multisensor machine reliably documents product quality. Maximum measuring precision Permits greater production tolerance reduces rejection rates and cuts your production costs. Reference in the measurement laboratory Universal testing options provide proof of quality for you and your customers. High testing speed Improves the reliability of testing through rapid measurement even for large quantities. Features OMS systems can be operated standing up or sitting down thanks to their adjustable base. The high-end control unit developed by Mahr is operated from an innovative terminal with integrated speed selection emergency stop and release buttons. The SP25 measuring probe can be adapted directly to the integrated interface of this control unit. The path measuring systems used are temperature-compensated and this is also an option for the workpieces. Design type Bridge-type measuring center with fixed bridge mobile measuring table and lower center of gravity. The side sections are integrated into the basic structure and the bridge sides are partly supported on this. All the axes are based on lapped granite guideways precision air bearings and backlash-free ball screws. The guideway for the Y table is incorporated in the machine base in a V-shaped arrangement. The X cage around the bridge is made from just two separate sections. The backlight has a telecentric design. Control unit 3- to 5-axis Mahr high-end control unit with integrated path correction Measuring system Incremental length measuring system with resolution of 5 nm (0.2 in) for standard systems and 1 nm ( 0.04 in) for high-precision systems Computer Industrial computer Pentium Windows XP Multilingual Technical Data in Brief Power supply Mains voltage 115 V 230 V 10 % Frequency 50 Hz 60 Hz 5 % Power consumption 1500 VA Installation conditions Ground vibrations 5 x 10-3 m s2 (corresponds to an amplitude of 5 m at 5 Hz) Humidity 40 % bis 70 % RL Permissible temperature gradient (relative to the reference temperature) 0.8 K h 1.0 K d 0.6 K m Remarks on length measuring uncertainty The length measuring uncertainty relates to a temperature of 20 C Optical measurements are performed with the 10x lens Mahr's conditions of acceptance apply The E3 value is determined using the touch sensor Camera-probe offset If using a camera and a probe the measuring range in the X-direc-tion is reduced by 50 mm (1.97 in) with the TP20 and TP200 and by 80 mm (3.15 in) with the SP25.
