Intelligent Digital Hardness Testing Machine Superficial Rockwell Härteprüfer
Production Instroduction:
Vexus SHR-45D is a half automatic and intelligent hardness testing machine, except to lift up the anvil to touch the specimen and select the test force: 15Kgf(147.1N), 30Kgf(294.2N) and 45Kgf(441.3N) in hand-knob manually, the other operations are entirely automatic.
The testing force, the process of loading, dwell and unloading, the hardness testing value, and the corresponding converted scale are displayed on LCD screen automatic.
Vexus SHR-45D system will remind the operator to select the corresponding testing force and indenter after scales choosing, and the automatic hardness testing and digital 0.1HR resolution display avoids the man-made error and enhance the measuring accuracy.
Vexus SHR-45D force knob adopts the metall material to replace the plastic material, it improves the instrument using-life greatly.
The minor load is applied first and a SET position is established on the dial gauge or displacement sensor of the Rockwell tester. Then the major load is applied. Without moving the piece being tested, the major load is removed and, with the minor load still applied, the Rockwell hardness number is automatically indicated on the dial gauge or digital display.
The diamond penetrator is used for testing materials such as hardened steels and cemented carbides. The carbide ball penetrators, available with 1/16 inch, 1/8 inch, 1/4 inch, and 1/2 inch diameter, are used when testing materials such as steel-copper alloys, aluminum and plastics to name a few.
Rockwell testing falls into two categories: Regular Rockwell testing (e.g., C and B scales) and Rockwell superficial testing (e.g., 30 N and 30 T scales).
High Rockwell hardness numbers represent hard materials and low numbers soft materials.
