Bre-Aut MAR for the testing of raw train wheels
Automated inline system for testing raw train wheels, providing precise, reliable and efficient inspection for demanding railway manufacturing processes.
Key Features
- Surface preparation of the raw wheel by milling
- The surface preparation and the measurement unit automatically adapts to the wheel size
- Integration of the hardness control automation with the existing in-line system
- 120 seconds for a hardness test including surface preparation
- Automatic wheel rotation for additional measuring positions
- Automatic evaluation of the tests to be performed according to the inserted tolerance parameters and automatic evaluation of the conformity or non-conformity of the measure according to the standards
Manufacturer
Ernst
Ernst have been driving the research and innovation in hardness testing for over 60 years. Ernst produce portable, automatic and bench-top hardness testers, covering all hardness testing requirements, together with products that extend their functionalities such as indentation readers and case depth analysers.
Customer Requests
-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 the specific regulations that impose no. 2 measurements at a distance of 25mm from the first test if it is outside the required range of hardness
Solution adopted
-System equipped with milling unit for 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
-Optimisation 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 test will be carried out. If both these tests give a positive result, the wheel is compliant
-If any of the conditions of the above point does not occur the wheel will be considered non-compliant
