Metal-cutting tools from Harbor Freight Ad Texas are a set of groups of tools of various shapes and sizes for processing metal workpieces. With their help, you can change the shape, properties and size of metal products by removing part of the material. The result of the work will be a finished part or a blank. The scope of application of metal-cutting tools is very wide. Directly or indirectly, it is used in most industrial sectors, in construction and everyday life.
What does a metal-cutting tool consist of?
Despite the existence of many groups and varieties, the structure of the metal cutting tool is identical. It consists of two parts:
On the working half there is a cutting part for cutting off a part of the metal and often a calibration part. It is used to restore the cutting elements during overfilling, to guide the tool during the cutting process and to finalize the surface to be processed.
Depending on the tasks set, the cutting part of the tool is equipped with such structural elements:
one or more blades; channels for coolant supply; grooves for chip removal, chip breakers and curlers; basic elements that are used in the manufacture, overfilling and control of various types of metal-cutting tools.
The fastening part is necessary for fixing the metal-cutting tool on machines, in machines or holding it in your hands. Rigid fixation of the fastening part in a certain position counteracts the cutting force during operation. Depending on the design of the fastening part, there is a plug-in metal-cutting tool (with shanks and holders) and a nozzle (with a hole for fixing on the mandrel).
The main types of tools for cutting metal.
There are two main groups of metal-cutting tools: manual and machine tools.
Hand tools are used without special metal-cutting equipment. It can be used both manually and in manual machines with hydraulic, electric and pneumatic drive. Chisels, hacksaws, files, files, etc. belong to this group.
The range of machine-made metal-cutting tools includes several subgroups of products:
cutters, broaches, cutters, thread-cutting, gear-cutting, diamond, abrasive, for processing holes and grooves.
Characteristics of a metal-cutting tool.
The requirements for the quality of metal cutting tools from Harbor Freight Ad Texas are reduced to two main tasks – compliance with a given class of precision and purity of metal processing and high productivity.
The most important characteristic of production work is the speed of processes. However, an increase in the speed of metal processing increases the risk of tool breakage: from blunting and coloring of the cutting edges to breaking. The resistance of a metal-cutting tool to high temperatures and wear determines its service life and performance.
The cutting ability is determined by the properties of the material of the cutting part. It is made of:
- high-speed tool,
- carbon steels;
- hard alloys of cobalt,
- tungsten, titanium;
- mineral-ceramic materials.
In recent years, the use of nanotechnology in the production of metal-cutting tools has been gaining momentum.
The above materials ensure the preservation of the shape and properties of the tool during the metal cutting process under certain conditions. For example, drills made of carbon tool steels are recommended to be used at low speeds, from alloyed high-speed steels at medium and high speeds.
