Overview

The KAIRDA Model D Impact device is standard for Leeb hardness testers and is suitable for routine Hardness testing applications. The device has specific Impact energy, size and weight parameters and is capable of measuring materials with a maximum Hardness value of 940HV. It is suitable for specimens of different surface roughness and thickness.

Features

Impact energy of 11mJ for conventional Hardness measurement 2. The ball head is made of tungsten carbide material, Hardness up to 1600HV, Abrasion Resistance 3. Impact device diameter 20mm, length 86 (147)/75mm, compact structure 4. Maximum Measurable Hardness up to 940HV 5. For specimens with a surface roughness of 1.6 μm 6. Supports specimens with a minimum test thickness of 5mm

Principle

The D-type Impact device makes the tungsten carbide ball head impact the surface of the specimen with an impact energy of 11mJ, and measures the hardness of materials according to the diameter and depth of the resulting Cedge. The device realizes accurate detection on different Hardness materials through specific Impact mass and ball head size.

Applications

Hardness measurement

Steps

1. Choose the support method according to the weight of the specimen: > 5kg direct test, 2~ 5kg need stable support, 0.05~ 2kg need dense coupling 2. Ensure that the surface roughness of the specimen meets the requirements of 1.6 μm 3. Check whether the thickness of the specimen meets the minimum 5mm requirement 4. For hardened layer materials, ensure that the layer depth is ≥ 0.8mm 5. Impact device perpendicular to the specimen surface for measurement

Notice

• The minimum weight of the specimen must be greater than 5kg • Specimens weighing 2~ 5kg need stable support • Specimens weighing 0.05~ 2kg need to be tightly coupled • The average surface asperity of the specimen should not exceed 1.6 μm • The minimum test thickness of the specimen is 5mm • Minimum depth of hardened layer material should be ≥ 0.8mm • Impact device is only suitable for routine measurement applications
