Wilson Hardness Days

Wilson Hardness Days November 4-5 2020

Since 1936, Buehler has been a leader in the engineering and design of metallographic equipment and since 2012, Buehler also became the manufacturer of the Wilson brand of Hardness Testers. Buehler is celebrating the 100-year anniversary of Wilson this year and with that we are excited to host the first ever Wilson Hardness Days. The Hardness Day celebration will […]

Verifying a Rockwell Tester with a Certified Test

Verify a Rockwell Tester with a Certified Test

How would you know if your Rockwell Hardness Tester will provide an accurate reading or is reliable? A typical way is to verify with a certified calibration test block. It is easy if you understand the basic principle of a Rockwell test and follow some simple guideline. A Rockwell test is the measurement of the […]

Why Buehler & Instron Improved the Vickers Hardness Testers

Why Buehler & Instron Improved the Vickers Hardness Test

Congratulations to Rudolf Mayer and Steve McMahon ITW, the parent company of Buehler recently recognized two outstanding engineers Rudolf Mayer, Buehler and Steve McMahon, Instron for their contributions to the design of the VH3100 /3300 micro-hardness products.   A Vickers hardness tester presses a pyramidal diamond indenter into the surface of the test specimen. The […]

CHD testing with DiaMet

Case Hardened Depth - CHD Testing with DiaMet

Focus on the task – improve efficiency Hardness testing is commonly used in the field of process control of heat treatment and to evaluate surface hardness and case-hardened depths of surface engineered materials. Hardness case evaluations can be highly automated, which can represent enormous savings in terms of time and efficiency. These systems can incorporate […]

Out-of-Box Concept with Mount Fixturing, EZ Clamp

Out-of-Box Concept with Mount Fixturing, EZ Clamp

Holding a metallographic sample both steady and level during hardness testing is essential to ensure accurate and repeatable results.  To make this mount both convenient to use, versatile and effective can be a challenge.  An innovative fixturing method was developed by Buehler’s Wilson Hardness Testing Group over 10 years ago.  This fixture is not widely […]

DiaMet Hardness Software – Weld Testing Using Vickers Hardness Scale

DiaMet Hardness Software – Weld Testing Using Vickers Hardness Scale

Welded joints are nowadays indispensable in the automotive and aviation industry. Welds usually combine metallic components to form a structure that is then assembled in production and assembly with other subassemblies. The welds must be able to withstand extreme loads as they are the weak points of the construction. Weld seam inspection is thus a […]

Time Study Case Hardness Testing of Automotive Crank Pins and Journals

Time Study Case Hardness Testing of Automotive Crank Pins and Journals

A study shows an operator time savings of 86% for making and measuring indents in three locations of crank pins and journals when using automation compared to manual testing. There was less part manipulation, fewer errors in data transcription and lower variability between operators performing tests.  Click here to view the full article.

Cuts Like a Knife-Hardness Testing Matters

Cuts Like a Knife-Hardness Testing Matters

In the highly competitive cutting blades indus­try, it is vital for the blade to have sufficient hardness to retain an edge, while too hard can cause brittle failure. When hardened materials are ground, residual heat may alter the microstructure and soften the blade edge. Testing the hardness of the cutting blades becomes challenging as indents […]

Material Thickness When Choosing a Rockwell Scale

Material Thickness When Choosing a Rockwell Scale

Are you concerned about which Rockwell scale to use for thin materials? Of primary importance in Rockwell scale selection is material thickness. Since the 30 Rockwell scales are distinguished by total test force as well as the indenter type, a load or force that is excessive for a given material thickness will ultimately be influenced […]
