There‘s many machining ways of metal parts,now let‘s see which ways are included!

Turning,Milling,Plane Bore,Drilling,Grinding

It‘s mainly about processing of removing material and those of not removing.Among them,the processing of removing material includes Car,milling,planer,grinding,laser,electrolysis,water processing.And those that don‘t remove material include forging,casting and so on.

1.Drilling
Drilling machine can also perform other processing drilling, workpiece positioning clamping fixed;The bit rotates on one side while drilling into the workpiece.

2.Turning and boring
Ordinary machine tool is one of the most common machine tool for turning workpiece turning to remove metal from the workpiece machining workpiece rotate at the same time, the cutting tool cut into the workpiece or along the workpiece cutting bore is the metal workpieces have been drilled or cast out of the hole to enlarge or for further processing of processing method on the lathe is boring by rotating a single blade cutter side facing the workpiece feed.

3.Milling
Milling is the use of rotary cutting tools to remove the metal, which has multiple cutting blades, called milling cutters.
We are professional in CNC milling parts,and there‘s advanced machine center machines in our factory.

4.Grinding
Grinding is the use of a grinding wheel called a grinding wheel to remove metal grinding to finish machining of workpieces, the machining method of processed workpiece size accurate, smooth surface grinding of circular workpiece workpiece side spin, a grinding wheel for rotating feed grinding flat workpiece, workpiece movement back and forth in rotating wheel is prepared The stiffness of the grinding process is often used to heat treated workpieces for final finishing, to the exact size.

5.Bullnose plane
Processing like planing,planer planing and slotting machine use single blade knife to produce precise plane.We should know  the use of the difference between the shaper to the cutting tool workpiece feeding, cutting tool movement back and forth on the workpiece for planer machining, cutter cut into the workpiece or feed to the workpiece, workpiece movement back and forth under the cutting tool.

We know the basic machining methods of machining, if enrich the theoretical knowledge and apply flexibly, we can process high-quality mechanical parts.
Now let me analyze the different processing types in detail, and how the cost and process effects it needs are cast.

Casting: the metal is heated to melt and then poured into the model for complex parts.

Classification of casting:
Sand mold casting: low cost, small batch, can process complex modeling, but may require a lot of post-processing.

Investment casting/lost wax casting method:
this kind of machining method has high accuracy and continuity, can also be used for machining complex modelling is relatively low cost, can achieve perfect surface effect, suitable for mass production.

High note casting: for machining error of complex shape because of the characteristic of the process itself, do not need post-processing after molding, products, however, only in the case of mass production can demonstrate the advantages of low cost method of die casting, machining cost is high, only in the case of mass production cost are reasonable but the cost of the final product is relatively low and the error is higher can be used to produce parts with thin wall thickness.

Rotary casting: an ideal method for processing small parts, usually used in jewelry manufacturing to reduce the cost of processing.

Directional solidification, the machine can produce good fatigue resistance performance of the very strong heat-resistant alloy pouring into the model, and then through strict control of heating and cooling process, to eliminate any tiny flaws in the plastic molding processing part.

Plastic forming process: refers to the metal high temperature heating in order to remodel, is labor intensive production.

Plastic forming process classification:
Forging: cold or hot work under the condition of punching and extruding to the metal mold, the simplest and oldest metal molding process.

The high temperature metal billet passes through a number of continuous cylindrical rollers, and the metal is inserted into the mold to obtain the preset shape.

Drawing steel wire: a series of drawing dies that are gradually reduced to make a thin filamentous process.

Extrusion: a kind of solid or hollow metal molding process with the same cross section shape for continuous processing, which can be used for high temperature operation and cold.

Impact extrusion: the process for processing small to medium sized parts with no funnel taper requirements is fast, and the cost of machining various wall thickness parts is low.

Powder metallurgy: can a processing black metal components can also processing non-ferrous metal components of process including mixing alloy powder and the mixture, press it into a mold two basic processes of metal particles through high heat sintering molding this process does not need to machine processing, utilization rate of raw materials can reach 97% different different parts of the metal powder can be used to fill the mold.

Solid forming parts:
Solid forming: refers to the raw material is used by some can be done under the condition of the modelling of metal strip, slice and other solid form belongs to the labor-intensive production and processing costs can be relatively cheap.

Classification of solid forming processing:
Spinning: a very common used in the production of circular symmetrical parts processing methods, such as plates, cups and cones when processing, the high-speed rotating plates push in also told the fixed on the lathe model, to achieve predefined shape in the form of the process is suitable for all kinds of batch production.

Bending: an economical process for processing any form of sheet, rod, and tubular material.

Continuous copper molding: metal feeding roller pressure between, in order to obtain continuous length, cross section consistent metal molding and extrusion process are similar, but has limits to the processing components of wall thickness, can only get a single wall thickness only on the premise of mass production, manufacturing cost is the most reasonable.

Press molding: the metal sheet is pressed between the male and the female die, which is used for machining the hollow shape. The depth can be shallow.

Punching: using special tools to cut out a certain molding process on the sheet metal, large, small batch production can be applied.

Blanking: similar to the punching process, the difference is that the former USES the offset part, while the latter USES the remaining part of the metal strip after the punch.

Shearing: cutting a sheet of metal in a cut, and cutting the paper from the best position with a pair of scissors is a good idea.

Chip forming: when cutting the metal, the cutting method of chip production is called chip forming, including milling, drilling, lathe processing and milling, sawing, etc.

No chip forming: use of the existing metal strip or sheet metal and so on carries on the modelling of no chip to produce this kind of technology including chemical processing, corrosion, electric discharge machining, sandblasting processing, laser cutting, water jet cutting and hot cutting, etc.
