Bre-Aut MAR Testing Raw Train Wheels

Bre-Aut MAR for the Testing of Raw Train Wheels

Portable, automatic, and bench-top hardness testers that cover all hardness testing requirements, along with products that enhance their functionalities, such as indentation readers and case depth analyzers.

Customer Requests: Automatic Brinell hardness testing of raw train wheels with the following specifications:

• Surface preparation at different depths and measurement of raw train wheels
• Need to measure wheels of different diameters (from 700mm to 1300mm)
• Speed up the entire test process
• Need to install into an existing production line consisting of machinery from other vendors
• Need to comply with specific regulations that require two measurements at a distance of 25mm from the first test if it is outside the required range of hardness

Solution Adopted:

• The system equipped with a milling unit for the surface preparation of raw wheels
• Creation of a transfer system that allows the rotation and transport of a wheel from the loading/unloading point to the measuring point
• Implementation of specific communication protocols for the exchange of signals and information with the PLC line controller
• Optimization of the transfer system controls to allow the wheel to be moved for additional measurement positions. If the first test falls within the specified range, the wheel is transferred to the unloading position, and at the same time, a new wheel is brought from the loading position to the surface preparation and measurement position to be measured. If the first test is outside the set range, it will be automatically rotated by 25mm, and a second and third tests will be carried out. If both these tests give a positive result, the wheel is compliant.
• If any of the conditions in the above point do not occur, the wheel will be considered non-compliant.
