DESTINATION
Special milling-boring machine with CNC УФ5527М is destined for complex machining a bogie bolster and a side frame in the bogies of freight railway cars renewal process. Machining is executed after reconditioning of the worn surfaces by electric weld deposition method. The machine provides simultaneous processing the surfaces of center bowl and sequential machining the planes of sliding blocks and the inclined surfaces of bogie bolster ( turn of a bogie is mechanized).
Design of a gadget has been made so that in it is possible, with a minor readjusting, to install and to machine in turn a bogie bolster and a side frame. When a couple of machines are delivered, each can be kitted with a gadget adjusted for machining a bogie bolster or a side frame. According to an order the machines are equipped with special cutting and auxiliary tools. Set of 4 designations of milling cutters and the holders provides full machining a bogie bolster and a side frame in a renewal process.
DESIGN FEATURES
A base machine is vertical milling machine with cross table mod. 6580Ф4 with CNC from “Siemens” Co. kitted with a gadget for the work pieces installation and clamping. The machine provides complex machining a detail at one installation in the gadget when the base characteristics of the machine are saved.
Clamping a tool in a spindle is mechanized. Clamping the work pieces, their turn are executed by fast mechanisms with manual drive.
When the gadget is removed from the table the machine can process any detail installed on its table. Application of CNC system with the machine gives 30% increase in machining precision and labor production capacity in comparison with a machine mod. УФ5527 without CNC.
