What do you know about planing, grinding and laser 3D printing?

1, planing processing - is a planing knife on the workpiece for the horizontal relative linear reciprocating movement of the cutting processing method, mainly used for the shape of the parts processing. The precision of planing is IT9~IT7, and the surface roughness Ra is 6.3~1.6um.
2, grinding processing - grinding refers to the use of abrasive, abrasive removal of excess material on the workpiece processing methods. Grinding is one of the more widely used cutting methods.
3, selective laser melting - in a slot covered with metal powder, computer-controlled beam of high-power carbon dioxide laser selectively swept over the surface of the metal powder. Where the laser goes, the surface of the metal powder completely melted and combined together, while the place not illuminated still maintains the powder state. The entire process takes place in a sealed chamber filled with inert gas.
4, selective laser sintering - is the SLS method using infrared laser as an energy source, the use of modeling materials are mostly powder materials. Processing, first preheat the powder to a temperature slightly below its melting point, and then in the scraping stick under the action of the powder paved; laser beam under computer control according to the layered cross-section information for selective sintering, a layer of the completion of the next layer of sintering, sintering is completed after the removal of all excess powder, then you can get a sintered parts. At present, the mature process materials are wax powder and plastic powder, with metal powder or ceramic powder sintering process is still under research.

5, metal deposition - and "squeezing cream" type of fusion deposition is somewhat similar, but the spray is metal powder. Nozzle in the spray metal powder material at the same time, will also provide a high-power laser and inert gas protection. This will not be limited by the size of the metal powder box, can directly manufacture a larger volume of parts and components, but also very suitable for localized breakage of precision parts for repair.
6, roll forming - roll forming method is to use a set of continuous rack to roll stainless steel into complex shapes. The sequence of rolls is designed in such a way that: the roll type of each rack can continuously deform the metal until the desired final shape is obtained. If the shape of the part is complex, up to thirty-six racks can be used, but for parts with simple shapes, three or four racks are sufficient.
7, die forging - refers to the use of die forging equipment in a special die forging blank forming and obtaining forgings forging method. This method of production of forgings accurate size, processing allowance is small, the structure is also more complex high productivity.
8, die cutting - that is, under the material process, the former process of molding the film positioned in the punch cutting die on the male die, close the die to remove excess material, retain the product 3D shape, and mold cavities to match.
9, die-cutting process - knife die - knife die downstream process, the film panel or line positioning on the base plate, the knife die fixed in the machine on the template, the use of machine downward pressure to provide the power to control the knife blade to cut off the material. He is different from the punching die is that the cut is smoother; at the same time, through the adjustment of cutting pressure, depth can be punched out indentation, half-broken and other effects. At the same time, the cost of the mold is low and the operation is more convenient, safe and fast.
10, centrifugal casting - is the liquid metal into the casting of high-speed rotation, so that the liquid metal in the centrifugal force under the action of the casting and the formation of casting technology and methods. Centrifugal casting casting, according to the casting shape, size and production of different batches, you can choose non-metallic type (such as sand, shell type or melt mold shell type), metal type or metal type in the coating layer or resin sand layer casting.
11, disappearance mold casting - is similar to the size and shape of the casting of paraffin or foam model bonding combined into a model cluster, brush and dry refractory coatings, buried in dry quartz sand vibration modeling, pouring under negative pressure, so that the model gasification, the liquid metal occupies the model position, solidification and cooling to form a casting of the new casting method. Vanishing mold casting is a new process of nearly no margin, precise molding, the process does not need to take the mold, no parting surface, no sand core, so the casting has no flying edge, burr and pulling the mold slant, and reduces the dimensional error due to the combination of the core.
12, squeeze casting - also known as liquid die forging, is to make the molten metal or semi-solid alloy, directly into the open mold, and then close the mold to produce filling flow, to the external shape of the part, and then apply high pressure, so that has been solidified metal (shell) to produce plastic deformation, the unsolidified metal to withstand the isostatic pressure, and at the same time, high pressure solidification, and finally obtain the parts or blanks Methods, the above direct squeeze casting; and indirect squeeze casting refers to the molten metal or semi-solid alloy through the punch into the closed mold cavity, and apply high pressure, so that it crystallizes under pressure solidification molding, and finally get the parts or blanks of the method.

13, continuous casting - is the use of through the crystallizer at one end of the continuous pouring of liquid metal, from the other end of the continuous extraction of molded material casting method.
14, pulling - is to use external force on the front end of the metal being pulled, the metal billet from the billet section of the mold hole in order to obtain the corresponding shape and size of the product of a plastic processing methods. Because the drawing more in the cold state, so also called cold drawing or cold pulling.
15, stamping - is by the press and mold on the plate, strip, pipe and profile, etc. to apply external force, so that it produces plastic deformation or separation, so as to obtain the required shape and size of the workpiece (stamped parts) forming processing methods.
16, Metal Injection - Molding (Metal Injection Molding, referred to as MIM) is a new type of powder metallurgy from the plastic injection molding industry derived from the near-net molding technology, as we all know, the plastic injection molding technology low price production of a variety of complex shapes of products, but the plastic products are not high strength, in order to improve its performance, the In order to improve its performance, metal or ceramic powder can be added to the plastic to get higher strength, good wear resistance products. In recent years, this idea has evolved to maximize the content of solid particles and in the subsequent sintering process to completely remove the binder and make the forming blank dense. This new method of powder metallurgical forming is called metal injection molding.
17, turning processing - refers to lathe processing is a part of machining. Lathe machining mainly with a turning tool on the rotating workpiece turning process. Lathe is mainly used for processing shafts, disks, sets and other workpieces with rotating surfaces, is the most widely used in machinery manufacturing and repair factories in a class of machine tool processing. Turning is the use of workpiece on the lathe relative to the tool rotation on the workpiece cutting method. The cutting energy of turning is mainly provided by the workpiece rather than the tool.
