Wheel, Wheelset & Bogie CNC & Machines


Bogie Load Test Stand
The Bogie Load Test Stand, which has stationary upper beams, is used for load testing and inspection of the bogies. The test is being performed at the ground level, so that there is no need for bogie lifting operation. The stand is designed to work for all kinds of bogie axle and wheel load tests. The Bogie Load Test Stand is able to do dimension tests on bogie (wheel dimension, axle parallelism, wheelbase, wheel diameter, etc), to calculate height tests and shim plate, to control bearing capacity simulations and computer aided bogie technical stability, to realize suspension stability tests and driving height adjustments, to record measurement data and to make evaluations and create reports based on such data.
Bogie Rotation Test Stand
The Bogie Rotation Test Stand can be used for both motor-driven bogies and carrier bogies. a structure enabling to test bogies by lowering rails. The stand is composed of 4 supports on each side, 2 of which are stationary and the other 2 are movable, which are required for positioning the bogie on horizontal axis and capable of supporting bogies during rotation tests. The main test equipment are connector connections such as bushing heat probe, wheel speed sensor, brake micro status, infrared heat sensors, accelerometer indicating any irregular vibrations occurring during rotation. Besides the system is able to test the entire brake system in terms of performance, including the capacity of brake cylinders.
Bogie Washing Machine
The Bogie Washing Machine is used to wash the bogie and all other smaller parts. The loading and the unloading of the bogie into the machine is done automatically and at ground rail level so that no lifting operation is required. There is also a movable platform system getting into the cabinet for loading easily dismantled and other parts. Both washing and flushing steps take place inside the cabinet with high pressure water system. Due to the potential safety risks, there are several safety countermeasures in the system: inside lighting with window, camera system to both door sides, automatic cycle stop in case of any issue happening during the washing process.
Bogie Dimension Check Machine
The Bogie Dimension Check Machine is used for testing mechanic elements having complex shapes and large sizes. The dimensional control of a bogie chassis is made by a rod set calibrated by suitable contact probs with high accuracy requirements from the user. The contact rods transfer 3-dimensional CAD drawings to a PC which compares data regarding chassis verticality and parallelism to sample set data in memory and prints without variation. The Bogie Dimension Check Machine is installed on a concrete block itself installed on an anti-vibration pads system in order to assure the stability of measurement.
CNC Above-Floor Wheelset Lathe
The CNC Above-Floor Wheelset Lathe is placed on the ground at rail level and is capable of the following tasks for dismantled wheel sets (both carrier and engine-driven) in addition to the functions of a normal lathe: shaping new and worn flanges (wheel rims), re-shaping worn wheels in compatible with profiles thereof, re-shaping internal and external flanges (wheel rims), shaping brake disc surfaces. A vibrated mill is used for peeling off brake discs. The CNC Above-Floor Wheelset Lathe has a chips conveyor for removing scraps away from the lathe. The software automatically compute new profiles, depths, and number of runs. The CNC Above-Floor Wheelset Lathe can support any type of rolling stock wheelsets.
Wheelset Assembly Press Machine
The Wheelset Assembly Press Machine is designed for fully automated assembly and disassembly operations of wheels. The machine is able to assemble all components (wheels, brake discs, transmission) in a single wheel set position. All parameter studies & data are executable and displayable on appropriate figures on the screen with exportable reports. The system can record and display the following parameters: wheel press force, piston distance and press-force diagram plot, press force against time (verification test), assembly position of each element, axial misalignment and redial graphic (wheels and brake disc), as well as wheel distances and brake discs distance. The shaft is positioned between centers for a perfectly center wheel sets during press operations and measurements.
Wheelset Balance Machine
The Wheelset Balance Machine is used to confirm the correctness of balances of a wheelset by virtue of its “massive” structure. The measurement cycle is fully automatic. The following data are available in the machine panel: unbalance values in terms of weight units (adjustable based on rotation diameter), position of unbalance in terms of sixty degrees and the multiples of sixty degrees (360°), rpm indicator for rotation speed, indicator for angular position in rotation, indicator for achieving specified thresholds, ability to read static unbalance and dynamic torque without repeating the movement, probability of unbalance vector, automatic diagnosis and calibration, etc.
Bearing Extractor Machine
The Bearing Extractor Machine is used to extract bearings from the wheelset. The system is mounted on the ground and the wheelset stays on the main rail tracks. The Bearing Extractor Machine is constituted of a piston head, a wheelset alignment system, a hydraulic system and a control panel unit.
Monoblock Wheels Ultrasonic Inspection Machine
The Monoblock Wheels Ultrasonic Inspection Machine is used for ultrasonic testing of monoblock wheels intended for detecting fatigue cracks which can be started under operation and spread among wheels. The system is completely underfloor and the train can passes on the whole system without any problem. During the ultrasonic inspection, the bogies are locked and lifted on small cylinders which then proceed to rotate. Ultrasonic and eddy currents tester perform the inspection procedure as the wheel set rotates and in case of defect discovered by the test, detailed images and characteristics of such defect is recorded, evaluated and documented.
CNC Vertical Wheel Lathe
The CNC Vertical Wheel Lathe is used for machining brake disks and monoblock wheel bodies. Its turret tools holder makes it so that the machine can proceed a full program on a side of the wheel without having to have any operator intervention. The CNC Vertical Wheel Lathe has a chips conveyor for removing scraps away from the lathe. The CNC Vertical Wheel Lathe can support any type of rolling stock wheels. The CNC Vertical Wheel Lathe can also be used as a standard CNC Vertical Lathe for other type of materials.
CNC Horizontal Axle Lathe
The CNC Horizontal Axle Lathe is used for machining axles of any rolling stock asset.  Its turret tools holder makes it so that the machine can proceed a full program on a side of the axle without having to have any operator intervention. The CNC Horizontal Axle Lathe has a chips conveyor for removing scraps away from the lathe. The CNC Horizontal Axle Lathe can also be used as a standard CNC Horizontal Lathe for other type of materials.
CNC Axle Grinding Machine
The CNC Axle Grinding Machine is used for grinding hollow axles of any rolling stock asset. The high accuracy of the measurement of this machine allows it to be very precise during grinding operations. The CNC Axle Grinding Machine has a chips conveyor for removing scraps away from the lathe. The CNC Axle Grinding Machine can also be used as a standard CNC Grinding Machine for other type of materials.
