A kind of laser cutting machine for carrying out Metal Cutting

Technical field

The utility model is related to the fields such as metal material production technology, is that one kind is used to carry out Metal Cutting specifically Laser cutting machine.

Background technology

Metal is that one kind has gloss (i.e. to visible ray strong reflection), is rich in ductility, the easily property such as conduction, heat conduction Material.It is relevant that the above-mentioned speciality of metal is all contained within free electron with metallic crystal.In nature, most metals with Compound state is present, and a few metals such as gold, platinum, silver, bismuth exist with free state.Metalliferous mineral majority is oxide and sulfide. Other existence forms have chloride, sulfate, carbonate and silicate.Link between metal is metallic bond, therefore arbitrarily more Change place all can again re-establish link, the reason for this is also good metal ductility.Metallic element is usual in compound Aobvious nominal price.Relative atomic mass it is larger be referred to as heavy metal.

Depart from because the electronics of metal is inclined to, therefore with good electric conductivity, and metallic element is usual in compound Band nominal price electricity, but when temperature is higher, because receive nuclear heat shock hindering, resistance will become big.Metallic molecule it Between link be metallic bond, therefore arbitrarily change position all can again re-establish link, this is also the good original of metal extensibility Cause.

In nature, most metals exist with compound state, and a few metals such as gold, silver, platinum, bismuth are deposited with free state .Metalliferous mineral majority is oxide and sulfide, and other existence forms have chloride, sulfate, carbonate and silicate.

Belonging to the material of metal has gold, silver, copper, iron, manganese, zinc etc..Under an atmospheric pressure and 25 degrees Celsius of normal temperature, the removal of mercury (liquid) outward, other metals are all solids.Most simple metal is silvery white (ash) color, and only minority is not that such as gold is yellow red Color, copper is aubergine.Band " Jin " is other mostly for metal.

It is metal generally by the Material Definitions with positive temperature resistance coefficient.Use containing the element that element is planted in 112 In periodic table, totally 90 kinds of metallic element.Positioned at the lower left of " boron-astatine line of demarcation ", in 5 regions such as s areas, p areas, d areas, f areas There is metallic element, transition elements is entirely metallic element.

In solid metallic conductor, there are many moveable free electrons.Although these electronics do not fetter any spy of what Determine atom, but all in the lattice of constraint what metal；Even under no External Electrical Field, because heat energy, these electronics are still Can randomly move.But, in conductor, average net current is zero.Wire inside arbitrary section is selected, is spaced at any time It is interior, from section while moving on to the number of electrons of another side, equal to the number that opposite direction moves past section.

Metal manufactures (smithcraft), is a kind of technology for metalliferous material being processed into article, part, component, Include the heavy parts of bridge, steamer etc., so engine, jewelry, watch trickle component.It is widely used in science, The different field such as industry, the art work, handicraft.
