Drills with mechanical fastening of replaceable many-sided neperetachivayemy hard-alloy plates

Drills with mechanical fastening of replaceable many - sided neperetachivayemy hard - alloy plates. Drills with MNP, including, a single - layer or multilayered wearproof covering are intended for drilling of openings on machines with ChPU, automatic transfer lines and modular machines, to satisfying norms of accuracy and rigidity established for them, by means of the drive of 7 - 30 kW. The radial system of rigidity "AIDS" has to be not less than 8000 - 15000 N/mm2 and dependences on diameter of a drill. Drills are issued with cylindrical and conic shafts, can have an internal supply SOZH and are equipped with two plates fixed by screws. At installation verified on the machine with application of special transitional cartridges and devices for a supply SOZH the following constructive options are possible: - the rotating drill - a supply SOZH is carried out through a special removable ring. - the unrotative drill - a supply SOZH is carried out via the nipple. Application of drills with MNP allows to receive openings not only the nominal size, but also to make boring at the radial shift of a drill, and also a coredrilling. Big advantage use of drills with MNP is a possibility of drilling at a zasverlovka on slanting, convex and to concave surfaces. When using drills with MNP productivity increases by 2 - 2,5 times in comparison with standard drills from quick cutting steel.
