The machine tools are mainly classified according to the processing method and the tools used. According to the national machine model preparation method, the machine tools are divided into 11 categories: lathes, drilling machines, boring machines, grinding machines, gear processing machines, thread processing machines, milling machines, planing machines, pulling Beds, sawing machines and other machine tools. In each type of machine tool, according to the scope of the process, the layout type and structural performance are divided into several groups, and each group is divided into several series (series).
In addition to the basic classification methods described above, there are other classification methods:
(1) According to the degree of omnipotence, the machine tool can be divided into:
1Universal machine tools have a wide range of processes, which can process different types of parts, such as horizontal lathes, universal cylindrical grinders and radial drilling machines.
2 Specialized machine tools have a narrow range of processes. They are specially designed and manufactured for machining certain parts or certain processes, such as shovel lathes and screw milling machines.
3 Special machine tools have the narrowest process range. They are generally designed and manufactured for the specific process of a specific part, such as various drill and boring machine tools used in mass production of automotive parts.
(2) According to the working precision of the machine tool, it can be divided into ordinary precision machine tools, precision machine tools and high precision machine tools.
(3) According to the weight and size, it can be divided into instrument machine tools, medium-sized machine tools (general machine tools), large-scale machine tools (quality greater than 10t), heavy-duty machine tools (quality above 30t) and super-heavy machine tools (quality above 100t).
(4) According to the number of main organs of the machine tool, it can be divided into single-axis, multi-axis, single-knife, multi-tool machine tools.
(5) According to different degrees of automation, it can be divided into ordinary, semi-automatic and automatic machine tools.
The automatic machine has a complete automatic working cycle, including automatic loading and unloading of workpieces, which enables continuous automatic machining of workpieces. Semi-automatic machines also have a complete automatic working cycle, but the loading and unloading of the workpiece still needs to be done manually, so it cannot be processed continuously.
Low voltage safety using AC12V power supply (Underwater Light need to be used with AC12V transformer,our lights do not include transformer ), is a safe voltage, can be used with confidence. Whether in water or on land, a variety of color changes will always create a romantic atmosphere, especially on rippled water surface, the effect will be better.
