Starrett's No. 3823 and 3824 Hardness Testers Enable High-Accuracy Measurements
L.S. Starrett’s digital Rockwell/superficial Rockwell benchtop hardness testers No. 3823 and 3824 include fully automated loading and unloading procedures.
L.S. Starrett’s No. 3823 and No. 3824 benchtop hardness testers use a closed-loop control unit with a load cell, DC motor, and an electronic measurement and control unit instead of traditional deadweights, enabling high-accuracy measurements at all test loads up to 0.5%.
The testers feature programmable scale conversions, dwell times, statistical capabilities and a test counter. They can test using a range of 30 different Rockwell hardness scales for carbon steel, alloy steel, cast iron and non-ferrous metals.
Suitable for both internal and external testing with a dolphin-nose design, the digital testers meet ISO 6508-2 and ASTM E18 standards. Each features
The Starrett No. 3824 hardness tester has an automated Z axis. The test process is automatically completed when users click the start button.Featuring a manual Z-Axis instead of an automated Z, the No. 3823 digital superficial Rockwell hardness tester is a lower-cost alternative.
Lockheed Martin’s precision machining of composite skin sections for the F-35 provides part of the reason why this plane saves money for U.S. taxpayers. That machining makes the plane compelling in ways that have led other countries to take up some of the cost. Here is a look at a high-value, highly engineered machining process for the Joint Strike Fighter aircraft.
Simple "roughness" measurements remain useful in the increasingly stringent world of surface finish specifications. Here's a look at why surface measurement is important and how to use sophisticated portable gages to perform inspections on the shop floor.
Virtually every machine tool builder lists, as part of a machine's specification, accuracy and repeatability figures. What's generally not given is the method used to arrive at the figures. Though these methods are defined in linear positioning standards, not all builders use the same standards.
