Brinell hardness testers
Eagle 3000 hardness tester
The Eagle 3000 is a fully automatic hardness tester, compliant with Brinell standards DIN ISO EN 6506 and ASTM E-10.
It features a rotating turret that supports indenters and lenses for a complete Brinell test. It allows measurements on large samples up to 500 mm high and 300 mm deep.
It features a movable stand and measuring head to ensure ergonomic settings for each operator, a Windows 10+-based industrial PC, and a 5 megapixel camera.
The integrated software allows for a complete and automatic reading of the indentation, with the option of also performing a manual measurement. The final results are displayed on a touchscreen LCD monitor, and all tests performed are stored.
Features:
• It can perform hardness tests with test forces in the range of 613.25 N to 29,413 N (62.5 kgf to 3,000 kgf) in accordance with DIN EN ISO 6506 and ASTM E10 standards for Brinell tests..
• It allows for easy selection of test forces.
• It can send data to a printer or network. The image of each indentation can be stored, allowing for measurement verification even long after the test.
• It is equipped with a high-precision 45° automatic rotating turret that supports indenters and lenses, allowing for precise viewing of the indentation image for further measurements.
• The interface can be set to English, French, German, or Italian. Other languages are available upon request. Furthermore, with just one click, it is possible to produce customized reports with the customer’s logo.
• It is designed for quick and easy repair and/or maintenance. The test head includes all critical systems (both the loading system and the optical reading system): this allows, in the event of overhaul or repair, only the head to be dismantled and shipped.
Bre-Aut SOR for the testing of finished train wheels
Requests:
Fully automatic Brinell hardness testing of finished train wheels with the following specifications:
• Surface preparation and measurement of finished trainwheels – need to measure wheels of different diameters (from 700 mm to 1300 mm).
• Speed up the entire testing 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 25 mm from the first test if it is outside the range of hardness required.
• Need to mark non-conforming wheels.
Adopted solution:
• Line equipped with lamellar wheel unit for surface preparation of finished wheels.
• Mounting of the entire hardness tester on a PLC-controlled motor-driven slide.
• Creation of a transfer system that allows two wheels to be transported simultaneously from the loading point and the measuring point under the hardness tester to the unloading 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 moved by 25 mm and a second and third test will be carried out. If both these tests give a positive result, the wheel will result compliant.
• If any of the above conditions do not occur, the wheel will be considered non-compliant and consequently marked with the spray paint unit located at the discharge position.
Bre-Aut MAR for the testing of raw train wheels
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 700 mm to 1300 mm).
• 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 two measurements at a distance of 25 mm from the first test if it is outside the required range of hardness.
Adopted solution:
• 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 25 mm 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.
Bre-Aut MAR with fixed clamps
Requests:
Replacement of an existing machinery:
• Automatic machine to be placed in production environment.
• Request for fully automatic machine cycle.
• Robust and durable machinery.
• Security system during machine operation.
• Possibility of processing and exporting measurement data.
Adopted solution:
• The provided machinery has a hydraulic principle to withstand production environments.
• PLC (Programmable Logic Controller) with touchscreen monitor for configuration and management of machine movements (input, output and signals), also includes the management of the hydraulic power unit.
• Oversized machine components allow continuous use of the instrument.
• Touchscreen monitor featured with Modbus serial communication protocol.
