Overview
The DGC Type C Leeb hardness tester Probe is an optional Impact device designed for the measurement of small or thin specimens and surface hardening, suitable for applications requiring High Accuracy hardness testing.
Features
1. Impact energy is 3 (Num), and the impact device has a lightweight mass of only 75g.
2. Hardness of ball head up to 1600HV, using Tungsen carbide material to ensure durability.
3. Ball head diameter 3mm, Impact device diameter 20mm, length 141mm, easy to operate.
4. Support the maximum test piece Hardness 1000HV, minimum test thickness 1mm, hardening layer minimum depth 0.2mm.
5. The asperity conforms to the N5 (ISO) standard, the maximum surface roughness of the specimen is 2.5UM, and the average asperity is 0.4Um.
Principle
The C Probe generates 3 (Num) of Impact energy through the Impact device, and the ball head contacts the surface of the specimen to form a Cedar. The Cedar diameter and depth (such as Cedar diameter 0.38mm, depth 12un) are used to calculate the Hardness value, which is suitable for small or thin specimens and surface hardening measurement.
Applications
Small or thin specimens, surface hardening
Steps
1. Connect the Probe to the Leeb hardness tester.
2. Ensure that the minimum weight of the specimen is 1.5kg, and the minimum weight of stable support is 0.5kg.
3. Coupled specimens with a minimum thickness of 0.02kg.
4. Impact measurement on the surface of the specimen.
5. Read the Crowd data and calculate the Hardness value.
Notice
• The minimum weight of the specimen is 1.5kg, and stable support is required.
• The minimum test thickness of the specimen is 1mm, and the minimum depth of the hardened layer is 0.2mm.
• The maximum surface roughness of the specimen does not exceed 2.5UM, and the average asperity is 0.4Um.
• The minimum thickness requirement for coupling is 0.02kg.
• Cutting diameter and depth data should be accurately recorded to avoid errors.
