¦ Know your Gauge Blocks

Ψ Selection Of Material

KCP makes gauge blocks in Steel, Tungsten Carbide & Ceramic material. The selection of material of gauge blocks should be based on the area of usage.

• Steel
Steel gauge blocks are widely used since most of the manufacturing components are made from steel which nullifies the measurement difference due to same thermal coefficient of expansion. Steel is ideal for regular use when used with proper care & regular maintenance.

KCP Steel Gauge Block features -
• Special alloy steel, properly heat treated & hardened to 800 HV giving it greater wear resistance.
• Dimensionally stable for long term use.
• Excellent surface finish with superior wringing quality.
• Coefficient of thermal expansion: (11.5±1)10-6k-1.
• Sets housed in a quality wooden case to dry environment and be protected against avoid moisture and corrosion.

• Tungsten Carbide
They are highly resistant to wear and thus ideal where the gauge blocks are used heavily. The study confirms that the Tungsten Carbide gauge blocks are of 10 times greater wear resistant than that of steel and thus extremely economical.

KCP Tungsten Carbide Gauge Block features -
• They are hardened to1400 HV, producing greater wear resistance.
• Dimensionally stable for very long use.
• Excellent surface finish with superior wringing quality.
• Coefficient of thermal expansion :( 4.7±1) 10-6k-1

• Ceramic
Ceramic gauge blocks are extremely resistant to wear and scratches. As a result, any minor damage to the wringability of their measuring face is unlikely. Corrosion resistant, these gage blocks are resistant to sweaty hands, and normal wear and tear.

KCP Ceramic Gauge Block features -
• They are manufactured from an exceptionally pure grade of zirconia ceramic.
• They are hardened to1400 HV producing greater wear resistance.
• Non magnetic, non corrosive, dimensionally stable for long term use.
• Excellent surface finish with superior wringing quality.
• Highly resistant to knocks and drops.
• Coefficient of thermal expansion: (9.5±1) 10-6k-1

Ψ Selection Of Grades

KCP product gamut covers gauge blocks of all grades. Grades are selected as per the area of its use. KCP offers all grades available in standards.

Grade 'K' : These gauge blocks are "Reference Standards" & used as masters for calibration of gauge blocks in calibration lab.
Grade '0' : These gauge blocks are "Lab Standards" & used for calibration of gauges & measuring instruments.
Grade '1' : These gauge blocks are "Working Standards" used in inspection room for day to day verification & calibration of gauges/measuring instruments.
Grade '2' : These gauge blocks are "Working Standards" used in production shop for inspection/ setting purpose.

Grade 00: These gauge blocks are" Reference Standards" & used as master for calibration of gauge blocks in calibration lab. These gauge blocks are no longer recommended in ISO 3650 standard & replaces with Grade'K' gauge block. However, Grade 00 gauge blocks are available on request.

Ψ Maintenance of Gauge Blocks

In order to increase the life of each gauge block under use, it is recommended to follow the below procedure :
• Each gauge block should be cleaned with soft lint free fabric.
• Ensure burr/dent free surface table when the gauge block is used for setting purpose.
• Avoid usage of damaged/scratched gauge blocks, which can spoil the accuracy of other gauge blocks.
• Damaged gauge blocks need to be replaced/repaired before it's use.
• Always protect gauge block immediately after it's use by applying thin layer of anti rust solution.
• Always follow correct wringing procedure to enhance the life of gauge block.
