More than 50 % of all tool made by the SKIF-M make mills for aerospace materials. Created as a result of own scientific researches executed in commonwealth with the leading scientific organisations of Russia, a mill for high-efficiency machining of titanium and heat resisting nickel alloys, as well as mills for high-speed machining of aluminium alloys occupy in the lead position in the world. Created in laboratory of plasma of the SKIF-M enterprise special coating of body of the mills, having low factor of a friction, considerably raises reliability of process of milling of difficult details of aerospace industry.
For draught machining of peripheral surfaces of aviation details from titanium alloys of type of rails, levers, arms and machining of internal surfaces of pockets by the SKIF-M enterprise the special program of trailer long edge milling tools in diameter from 25 to 80 mm, equipped with indexable high-precision inserts with standard radiuses 0,8мм, 3мм and 4 mm is created. The cutting part of these mills is executed in the form of a screw surface with an angle of lead about 45 degrees. Internal channels for giving of a cooling liquid guarantee effective heat removal and removal of a shaving from a cutting zone. The special arrangement replaceable inserts on a cutting part of mills provides the minimum fluctuations of forces of cutting at processing of preparations with a variable allowance, characteristic for details of the flying machines received also by a method of punching.
New mills can be used equally effectively as on modern high-efficiency machine tools of the increased capacity, and on the traditional machine tools of type FP17 till now widely used at domestic factories, letting out flying machines and accessories to them.
High efficiency of the SKIF-M tool at milling a hard materials is provided not only thanks to specially created geometry of a cutting part of the tool and its optimum design, but also and thanks to nanocomposit coverings cutting inserts, carried out in Belgorod on unique technology.
The program includes 638 standard sizes of face, trailer and long edge mills in diameter from 16 to 160 mm with indexable inserts.
