Leipziger Spring Fair 1979 At the Leipzig Spring Fair 1979, the Ministry of Posts and Telecommunications of the German Democratic Republic issued two multi-colored special postage stamps. Special cancellation from March 6 to May 5, 1979 25-pfennig value: horizontal drilling and milling machine Horizontal drilling and milling machines are universal machine tools. Drilling, milling and facing work can be performed in one clamping on four surfaces of a workpiece. Additional equipment allows the processing of a fifth surface - or any other surface - without re-clamping the workpiece. The machinable range of workpieces extends from plate-shaped and box-shaped parts of machine and vehicle construction to complicated parts for aircraft and turbine construction. The optimum adaptation to the machining tasks is achieved by types, equipment variants and automation levels such as numeric position displays, numerical position controls and numerically controlled machining centers with automatic tool change. In principle, it is possible to mount all NC and CNC systems. Table type: "BFT series" Spindle diameters 80, 90, 110 and 130 mm, equipped with turntable, attachable surface support and jib Cross bed type: "BFK series" In surface support and milling spindle design with spindle diameters 110, 130 and 150 mm. With diameter-programmable design support, holes of different sizes and faces can be machined automatically in NC mode without tool change. Panel type: "BFP series" with spindle diameters 130 and 15O mm, this type is particularly suitable for machining large heavy workpieces. Characteristic feature is a distinctive modular design that allows the construction of the single machine to the production line for complete machining of workpieces. The manufacturers of these horizontal drilling and milling machines are VEB UNION Gera and UNION Karl-Marx-Stadt, which with more than 100 years of experience are among the leading European specialist companies in their sector. UNION horizontal drilling and milling machines are exported worldwide through WMW export import.
