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.
