Starrett Introduces Digital Force Testers for High-Volume Basic Production Testing

FMM force testers provide fast, versatile, affordable, motorized, digital force testing

Published: Wednesday, April 25, 2018 - 11:00

(Starrett: Athol, MA) -- The L.S. Starrett Co. has introduced a series of motorized digital test frames for performing a wide range of basic, high-volume, in-situ manufacturing, force-testing applications including tension, compression, flexural cyclic, shear, and friction. The Starrett FMM digital-force testers are part of the new Starrett L1 line of entry-level, computer-based, force-measurement solutions. Optimized for production and quality control testing, the versatile, innovative architecture of the L1 system is designed for fast, easy-to-use, reliable and repeatable operation.

What makes Starrett FMM force testers exceptionally unique is their ability to be used with either Starrett L1 software for computer-controlled testing, or with a Starrett DFC digital-force gage. The DFC gage lets users control the speed and travel of the FMM series, providing a single operator interface for control and testing. Using the DFC series on an FMM test frame, load, distance and break-limit testing can be performed simply at an economical price and with excellent accuracy of better than 0.1 percent.

“The FMM test frames were designed to operate two ways—with our L1 software for customers seeking full computer control in a Microsoft Windows environment, or via our DFC force gage mounted on the column for customers preferring maximum application versatility and cost effectiveness,” says Emerson Leme, head of the metrology equipment division at Starrett. It’s a revolutionary concept.”

The Starrett L1 software offers simple, fill-in-the-blank templates that let users create, perform, measure, and analyze their test in seconds and perform limit testing, break testing, constant-hold testing, cycle testing, and more. Touch screen control simplifies operation and the high resolution display shows results in tabular and graphical formats. Tolerances can be applied for immediate pass/fail indication. Raw data can be exported to Excel for reporting and statistical analysis.

Starrett FMM series test frames are available in three force capacities: 110lbf, 330lbf and 550lbf (500N, 1500N and 2500N), and are furnished in a standard travel length (20 in./508 mm) or an extended travel length (30 in. /760 mm). FMM test frames feature a small footprint for small work spaces. The frames are just 11 inches wide by 16 inches deep. All frames have a speed range from 0.02 to 40 inches per minute (1 to 1000 mm/min). Position accuracy on the FMM test frames is better than 20 microns and speed accuracy is better than 0.1 percent at full load and at maximum speed. Jog keys and an LED display aide manual operation. Adjustable travel limits may be used to prevent over-travel conditions.

The FMM test frames also feature an adjustable base plate made of cast aluminum for exceptional rigidity and durability. Inspectors may use metric or imperial threaded test fixtures and clevis adapters. The base plate is adjustable so that sample alignment can be performed in seconds without special tools.

The Starrett FMM testers’ mechanical design incorporates a preloaded, grounded ball screw with a linear rail for precise, repeatable travel. Frames are capable of performing hold tests as well as cyclic testing for up to 27-hour durations. Bench clips are supplied if users want to permanently secure the frame to their work bench.

The FMM test frames are CE-compliant and have USB and RS-232 communication. Plus the frames have configurable I/O for use with annunciators or other external devices.

When more sophisticated and complex testing is required, Starrett also offers a range of force solutions via its L2, S2, L2 Plus and L3 systems. Starrett force measuring equipment is manufactured in the United States and is available to order now in several configurations including handheld force gages and digital and manual force testing frames.
