The machine is designed for complex processing of the superstructure after surfacing during depot repair of the bogie of freight wagons models 18-100, 18-578, 18-194-1.
The machine for one installation of the spider beam provides consecutive machining of:
- thrust bearing profile;
- kingpin bore;
- 4 centring grooves (inclined surfaces);
- 2 slides (bogie 18-100).
Machining of the thrust bearing profile is performed by milling blocks installed in the universal 4-spindle attachment and providing the drawing dimensions of the thrust bearing.
The kingpin bore is machined with a countersink.
Inclined surfaces and slides are machined sequentially with an end mill.
