Rationalization proposal Lyubertsy student of secondary school № 42 of Yuri Furmanov. How to ensure all novice turners cutters? Almost every school workshop this problem exists. The HSS tools quickly become dull and break in inexperienced hands boys, standard tool holders with brazed them on the plates from hard alloys are not suitable for school machines high. The same applies to the most affordable cutters with exchangeable sintered plate (durable, able to withstand the most critical conditions).
“SCHOOL” CUTTER
The compressor is one of the machines, which are frequently encountered in various production areas. Among the vulnerable sites that require durability and long remained a piston ring. It wear led to the deterioration of integrity, performance and efficiency of the unit.
Remember PushPull fabulous animal which could jump not only forward but also backward, because instead of a tail he had a second head? About it can not help reminiscent of the original bilateral cutter, manufactured by the innovators of the Gorky machine-tool production Association. Tool on a conventional tool holder has two cutting inserts mounted on carbide lining and is mounted to the top clamps. Under the clamps located struzhkolomy.
From circular knives, no matter where they worked in agricultural units, in the fields or in industrial plants, — wear out really fast sharp working edge. Therefore, innovators tend to find the most effective method of restoring the load of the tool.
Can we call today an industry where not carried to its good welding is a fast and reliable method of joining parts from different metals and alloys. Not accidentally, the interests of many young innovators are concentrated “around the electrode.” The army’s innovators N. Khvorostiv M. Bokov, S. Privateer built the unusual torch for arc welding in shielding gases. It is intended for the qualitative connection performance parts, made of steels and aluminum alloys.
Existing disk device for mechanized spreading of fertilizers do not always provide the uniformity and range of distribution of fertilizers on the field.
…drill press, which I use for several years and are quite happy. Make it can anyone who loves tinkering. The design shown in Fig. The drill is fixedly mounted in the upper part of the Jack by two clamps of flat steel. Gasket between her and Jack is a wooden block. The table is made of steel profiles, U-shape, it fit in with the moving end of the Jack bolt M8. To make the machine more stable, its abutment provorachivayut to any lasting basis.
