To perform various tasks, it is required to use gauges, brackets, rings, threaded and smooth plugs, which are made according to the customer's dimensions or according to GOSTAM, as well as patterns, thread-rolling rollers, shock stamps and others used in production buy measuring tool .
For the manufacture of these tools, a material is used that has the following properties:
Hardness, which is an order of magnitude higher than the hardness of conventional materials;
Increased durability;
Heat resistance and thermal conductivity;
Mechanical strength.
High-speed steels and some other types of alloy steels correspond to all the specified properties. Recently, the use of simple carbon steels has been rather intensively reduced. High-alloy steels are used, which are characterized by higher strength characteristics, heat resistance and corrosion resistance. The hardness that is inherent in high speed steels is the main and most important, but not the only one. So most small high-speed tools break before the tool is completely worn out. This indicates the property of strength and toughness of steel. Brittleness, cracking and other chips are prevented by a combination of toughness and strength.
An important area of application is the regrinding of taps from large sizes to smaller ones, as well as the manufacture and regrinding of thread-rolling rollers from D 100 to D 205 (from M 6). In addition, measuring tools are in demand: wires, rollers, cones, patterns, shock stamps.
