West Manufacturing News • March 2025 • Faster, Accurate Measurement and Inspection

The L.S. Starrett Co. has expanded its AVR Vision Metrology Line with the introduction of the AVR400 CNC Vision System, the largest benchtop platform to date from Starrett with stage travel that is twice the speed of previous Starrett AVR models. The stage travel is 15.8” x 11.8” x 7.9” (400 mm x 300 mm x 200 mm) in the XYZ axes with a speed of up to 120 mm/sec.

“We are very pleased to offer customers a new, faster vision system capable of measuring a broader range of larger part sizes, as well as providing the ability to put more parts on the stage at one time,” said Mark Arenal, General Manager, The L.S. Starrett Company—Metrology Division. “Users will reduce inspection and measurement time while maintaining accuracy.”

The Starrett AVR400 offers full CNC capabilities, including XYZ positioning and comprehensive zoom and telecentric lens options. Users can also choose to use motorized manual positioning via a pendant with a joystick and track ball. Equipped with the M3 software package from MetLogix, a traditional mouse as well as a touchscreen monitor make user interaction easy and intuitive.

Auto part recognition enables creation of a part measurement program that comprises the desired features of a part for inspection, which can automatically be saved in the system or to a network. Programmable light output options can be built into the program as defined steps, including being called up as the part recognition program initiates. Once the program is created, placing that part within the camera’s field of view allows for the saved program to initiate and run the inspection. A Renishaw touch probe may also be utilized for quick acquisition of discreet points along a part’s profile as well as Z-axis measurements.

For high stability, the AVR400 features a granite base. An extensive line of accessories is available, including a modular system workstation on rolling caster wheels, providing convenient repositioning on the shop floor and in QC labs. The AVR400 Vision Metrology System is made in the USA.
