The new TESA® UPD Gage Block Comparators from Brown & Sharpe improve calibration accuracy and reduce the time required to calibrate a set of gage blocks by up to 75 percent. TESA UPD Gage Block Comparators can be used for both direct and comparative measurement of gage blocks. In the direct measurement mode, the nominal length of the gage blocks to be compared can vary up to 25 mm, approximately 1 inch. In the comparative measurement mode, gage blocks of the same nominal length can be checked.
With the nine-piece TESA UPD set, users can check more than 90 percent of a 122-piece gage block set using the same reference gage block, reducing calibration time. The reference gage set can be reduced by nearly 80 percent when compared with traditional gage block comparators, with resulting lower gage block supply and calibration costs.
Single or dual template systems provide optimum gage block handling. The new dual template system provides maximum protection for reference gages since the master set can be left in the park position until needed. The dual template system also reduces the travel distance of the master gage by nearly 70 percent, reducing the risk of damage during the measuring process. With the single template system, the reference gage and the gage block move together during measurement cycles.
TESA UPD Gage Block Comparators are equipped with Heidenhain high precision incremental probes. They can be equipped with a temperature acquisition device that captures the temperature of the two gage blocks, the measuring table and support. TESA UP software processes length and temperature values as measured and controls the measurement cycle. It makes all relevant corrections automatically, accounting for actual length of the reference gage blocks, flattening compensation, and temperature variations. Output results are in accordance to ISO 3650. This advanced software is menu driven by and works with Windows 95 or later, Windows NT and ME. It is available with preset gage set compositions.

In addition, the REFERENCE coordinate measuring machine available from Brown & Sharpe is a high accuracy, high performance scanning machine that offers advanced dimensional data gathering and analysis capabilities.
The REFERENCE CMM uses advanced Leitz Scanning Probe (LSP) technology for high speed scanning of geometric shapes and free form surfaces. LSP technology combines and optimizes all facets of the probing process including automatic probe weight compensation, advanced motion controller firmware, and advanced filtering algorithms to support high-speed, high-accuracy open and closed loop scanning applications. This advanced LSP technology facilitates both high speed scanning of known and unknown contours and the advantage of measuring with very long probe extensions.
The control system incorporates continuous axes motion interpolation, integrating axes movements by eliminating stops and corners. Adaptive scanning modes improve scanning accuracy and throughput by optimizing 3D vector path control for parts with a changing rate of curvature. The result is a smooth, continuous probe path that increases machine throughput by an additional 30 percent.
The REFERENCE CMM features an all-aluminum ultra-rigid frame with a heavy, stable granite table to resist vibrations. Tricision(tm) bridge design orients the bridge for optimum stiffness-to-mass ratio. Dovetail guideway construction with wrap-around air bearings improves accuracy and repeatability. An automatic linear thermal compensation system consisting of sensors installed in each axis scale allows the REFERENCE to adapt to ambient thermal conditions. It is suitable for all high accuracy applications such as turbine blades, gears, and screw and scroll compressors. Long probe extensions and sophisticated engine valve analysis software make this CMM an optimum measuring solution for automotive power train applications.
The REFERENCE CMM can be equipped with QUINDOS(r) or PC-DMIS(r) measurement and inspection software. Options include an automatic probe changer, rotary table, and interface to accommodate manual and automatic part loading systems.
