3. Can you provide a discount for your goods?
A: Yes,we can offer you a 10% discount if you place an drder of 300 sets one time...
- Q: How to improve the surface roughness of casting parts?
- First, the accuracy of the model should be improved; two is to change the molding technique; the three is the coating; and the worker's technical level.
- Q: What are the requirements for casting steel castings?
- 1, high quality requirements of the surface or the main processing surface should be placed below.
- Q: What method of casting does not rust? I think the sample is like oil
- The surface of a general casting is easy to rust. In order to prolong the rusting period, antirust paint or antirust oil is usually sprayed. What you said should be anti rust oil.
- Q: What are the casting parts processing engineering?
- Among them, special casting has metal mould casting, pressure casting, low pressure casting, lost wax casting (also known as precision casting), shell casting, lost foam casting, centrifugal casting, continuous casting, V casting, and clay casting
- Q: Question, such as title, I hope I don't copy the definition of rolling and casting in Baidu encyclopedia, thank you
- Service performance: heat conductivity, friction reduction, shock absorption, heat resistance and corrosion resistanceTo compare these properties, it depends on the specific material, structure, and use of the parts. Otherwise, there is no comparisonS
- Q: How to cast iron and wrought iron collocation
- 3, if you have a file in the hand, can be used to file to see finish can also make a judgment from the file down the iron can also be seen, but this is beyond your request, it can be done in the factory. 4, if placed in the grinder grinding, see iron spark from a judge or iron wrought iron, but this is only to do in the factory. About it, may not be full, but through these methods, generally can distinguish between iron or wrought iron.
- Q: How can the casting be quenched and tempered?
- Return, general castings (especially steel castings) commonly used heat treatment process is normalized and tempered. Of course there are completely by annealing or remove stress annealing...
- Q: Would you please tell me how to use casting parts for a year?The cast of an aircraft wing needs to be put aside for a year before it breaks;Does anyone know why?
- 3, the resonance method is cast on its resonant frequency vibration 1060ndn, to eliminate the residual stress in casting.
- Q: Lathe processing stainless steel casting parts to use what type of tool, the speed into the amount of how much tool angle
- There is YW1 best, if not using YG6X, YG8 is ok!The speed should not be high, the greater the diameter, the lower the speed! For example, a diameter of 100 mm, speed is not greater than 80 rpm, each point is good!The main tool is the front angle to be larger, more than 6 degrees, and the groove should be wider and larger to reduce the cutting resistance! When the rear angle is properly reduced and the strength is increased, it is recommended to take 3 degrees.The main components are: spindle box, exchange gear box, feed box, slide box, tool post, tail frame, light bar, lead screw, bed, foot and cooling device.Spindle box: also known as the headstock, it is the main task of the rotary motion of the main motor came through the transmission mechanism of a series of positive and negative spindle to be required two different steering speed, the spindle box gives impetus to the movement of the box. Medium spindle is the key part of lathe. The stability of the spindle on the bearing directly affects the quality of the workpiece. Once the rotation accuracy of the main shaft is reduced, the value of the machine tool will be lowered.
- Q: Which master knows how the casting tolerances for malleable iron, gray iron and ductile iron should be chosen? Hurry up, thank youCan you provide a tolerance scale for castings, please?
- Our country has a national standard for casting tolerance levels. This national standard applies to you in malleable iron, grey cast iron, and ductile iron.
