Hamar Laser Measurement System Enables Fast, Accurate Calibration

Source: Hamar Laser Instruments Inc.

Hamar Laser Instruments Inc.’s L-703SP surface plate calibration system
offers high resolution and accuracy, easy setup and training and fast data collection. It is highly repeatable with flexible measuring increments, high resolution and accuracy, easy setup and training, as well as fast data collection.

The L-703SP System is said to be 30-40% faster than electronic levels, more reliable and repeatable from one tech to the next. In addition, the L-703SP is set up directly on surface plates, intended for each line segment setup to be simpler than autocollimators and laser interferometers, which require floor mounting and touchy setups.

The L-703SP System uses Hamar Laser’s L-703S spindle and straightness laser and T-1297 three-axis wireless straightness target. Compact and lightweight, the custom laser is designed for high-resolution straightness applications, such as surface plates, machine-tool guideways and spindle axes. The T-1297 target features a super-linear, two-axis position-sensitive detector (PSD) with a resolution of 10 μin. (0.25 μm) and mechanical repeatability of ±10 μin. (±0.25 μm).

The L-703SP features the Windows-based Plane6 surface plate calibration software, which offers a three-step calibration procedure and built-in tolerance table that can speed setup and data-taking and generate a full-color report. The system also includes the A-703SP-LM laser mounting fixture, A-703SP-SE straight edge and ruler, A-1297-SP high-accuracy flatness-measuring base and A-703SP-SE-CLT corner and mid-point locating tool.
