Hardness test benches

The hardness tester for rims is an electromechanic special hardness tester, that is specialised for rim testing. The test frame divides in samples table, guidance device with load device followed from the test head.

This hot hardness testing machine is used to determine the hardness of metallic and ceramic high temperature materials. It enables the determination of the Vickers hardness in vacuum in the temperature range of 300-1500°C and is intended for use in the materials testing laboratory.

The testing portal is used for the hardness testing based on the Rockwell method HRC according to DIN EN ISO 6508 at large and heavy elements. The machine frame is built as a portal with a clear width of 1360mm and a clear height of 1000mm above the ball caster table, so that components up to a maximum width of about 1200mm and a maximum height of about 900mm can be crossed and tested. The minimal height of the specimen is 100mm.

Hegewald & Peschke MPT GmbH has developed a robot-based hardness testing station which can be used to fully automatically test the Brinell hardness of components and finished products. The fully automated hardness testing centre gives new impetus to industrial quality assurance as it offers high test speeds and evaluation independent of the user as well as automatic registration of the test results. If required, the entire production series can be thoroughly tested without the results having to be manually evaluated.

Hegewald & Peschke Meß- und Prüftechnik GmbH has provided automotive suppliers with further hardness testing systems for determining the surface hardness of automotive crank shafts and cam shafts.

This hardness test bench for crankshafts is a especially for this case constructed machine using a Rockwell- testing head. Clamping and unclamping as well as the positioning of the test piece are manually operated. The positioning as well as the clamping of the test gripper (with hardness test head) happens motorised due to operating the corresponding controls and sensors.

The Rockwell hardness testing equipment for crankshafts is a device designed particularly for this application purpose using a Rockwell measuring head of the company ERNST.

This hardness tester for evaluation of Jominy-tests is an automated system composed of the following described components:

Sample parameters

• Circular blanks  Ø14 to Ø36 mm with edge heights of 1.0 to 3.0 mm
• Weights of the circular blanks from 1 g to 15 g
• Sample material ranging from homogeneous to multi-layer material compositions with electroplated coatings  
• Sample surface of Al, Cu, Ni, Ag, Au, St with surface structures ranging from matt to high gloss
