Marposs Corp Universal Measuring Gauge for Grinders UNIMAR™

DESCRIPTION UNIMAR measuring heads are the go-to solution for comprehensive process control on grinding machines. They are the essential components for building integrated, high-performance measurement systems. Types of application Smooth/Interrupted outer diameters Grinding Smooth/Interrupted inner diameters Grinding Surface Grinding Centerless Grinding Machining Centres High precision lathes Lapping machines Super-finishing machines Post Process measurement stations BENEFITS Versatility Flexibility Compactness Accuracy Reliability Metrological performance Robustness Ease of installation Serviceability Thermal stability VERSIONS UNIMAR gauges are available in a variety of versions, each designed to meet specific process requirements—ensurin g unmatched flexibility, precision, and reliability across different grinding operations. UNIMAR S – High Precision for sub-Micron-Level Tolerances The perfect solution for ultra-precise grinding systems, UNIMAR S excels in applications where top performances and small ranges are required, such as in the injection systems industry. Exceptional linearity, repeatability, and thermal stability guarantee consistent, high-precision results—on both smooth and interrupted surfaces. UNIMAR R – Extended Retraction for grooves UNIMAR R features a unique mechanical design that enables contact retraction up to 14 mm, making it ideal for complex parts like cams or bearing grooves. In addition to standard configurations, this version is available in special models—including one made of non-magnetic steel. UNIMAR W – Wide-Range, Flexible Measurement Equipped with a dedicated transducer, UNIMAR W offers a dynamic measuring range of up to 12.5 mm. When paired, they can measure diameters across an inch (25.4 mm) span without mechanical adjustments. This makes it the ideal solution for high-mix production where part types vary frequently and flexibility is essential. UNIMAR P – Precision Part Positioning Designed for part positioning during the grinding cycle, UNIMAR P includes a rear setup system that ensures precise over-travel adjustment. Whether for active positioning (by moving the part or the gauge) or passive positioning (measuring part position), this head delivers reliability in exact alignment control. UNIMAR L – Positioning with Extended Measurement Ranges Built on the same principles as UNIMAR P, UNIMAR L adds the advantage of larger measurement ranges. It’s ideal for applications requiring positioning on a bigger range, offering the same setup flexibility for both active and passive positioning cycles. UNIMAR A – Absolute Measurement, No Reference Required For applications demanding masterless rather than comparative measurements, UNIMAR A provides accurate measurement over a range of up to 16 mm. It eliminates the need for a reference master for each diameter—streamlinin g the measurement process. Versions are available with or without retraction and are suitable for both continuous and interrupted surfaces. They can be used for diameters and length measurements.
