Q:Explain the heat treatment effect of casting parts, forging parts and welding parts
The three methods of metal processing have one thing in common. They are hot working, which are different in temperature and range of processing. Ductile cast iron is widely used because of its brittleness and poor impact. Heat treatment of cast iron usually adopts the annealing process, reduce the casting effect: 1 because of the internal stress caused by the thermal expansion and contraction, reduce the deformation after machining, decrease surface hardness, improve machining conditions;
Q:Is the cast steel a casting part?
Cast steel is divided according to material, as well as cast iron parts, cast aluminum parts and so onCasting parts are divided according to the method, as well as forging partsCast steel parts must be casting parts
Q:What is the ejection angle of the die casting (Tan Gang)?
Especially deep hole, and customers to discuss, generally take 0.3-1 degrees is enough
Q:What are the casting parts used to test shrinkage holes?
1. anatomy. It is easy to slack off by sawing and machining.
Q:What kind of flaw detector is better for casting parts?
If you want to detect internal defects, you can use ultrasonic flaw detector, ray flaw detector can also, but the ray of the safety protection level is too high, not recommended priorityMacro Xu flaw detector answered, such as the magnetic particle inspection machine has the demand can contact us, Baidu "macro Xu flaw detection""
Q:What are the effects of stiffeners on castings, or on welded parts (for 2 tons or less), casting or weldments on stiffeners?
4, the performance requirements of the steel: whether castings or welding parts, there may be quality defects, but the casting will generally be worse than the weldment.You should be able to make a choice in the end.
Q:Cause of choking of casting parts
The reason is not in the coated sand, see coating gas evolution, the best use of zircon powder coating (low gas evolution), there is a mold according to a vent needle, this depends on your way is flat or vertical pouring pouring pouring, if vertical pouring, venting pin on the die, and the big piece how could the plane, pouring water flat, a breath, a taboo ah!
Q:When the blank is a casting, the margin is evenly distributed, how should rough machining?Please help friends from mechanical classes.There is another problem: in the NC milling plane contour machining, when the rough margin is large, how to deal with.Who can help in time, add 20 reward. Urgently!!
Problem one,1, according to drawings, castings, material requirements and machine power, choose the right diameter of roughing tools, and can process this material blade type.2, according to the actual size of the casting blank, calculate the number and path of the knife, pay attention to small cutting depth, large feed, cutting width, to ensure that the tool diameter 80 - 90%, the amount of not full knife cutting, this tool and machine tool damage.Question two,If they can not change the casting blank allowance under the condition that the quantity large diameter cutter, such as milling cutter main angle 7560 degrees can give reasonable processing parameters, the same cutting depth should not be too large, because in the same machine power, tool diameter increases, cutting depth will need smaller.
Q:Why does the surface of stainless steel casting mirror mirror ripple?
Because the grinding machine is layer by layer. And the material inside the casting is not completely uniform.
Q:the parts of the threaded hole is casting, casting the hole directly, and then tapping or casting, and then punch 10When the casting is ready, punch it again before tapping it Is the hole casting good or is it punched and tapped on the drilling machine after casting?
If it is not directly cast hole hole, later processing, large pores may be directly cast out,
