Q: What are the casting parts used to test shrinkage holes?
3 fluorescent magnetic powder, this method can also be found in part.
Q: Why does the precision casting factory not usually make iron castings?
Jiangyin Lin Xing stainless steel (precision manufacturing) Co., Ltd. to provide professional precision casting
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: After reaming, the roughness can reach several levels, that is to say, the sample.Casting parts in rocker arm drilling, reaming, roughness, block. After reaming, the roughness can reach several levels, that is to say, the sample.
Not processed, do not understand your problem... There's something wrong with the drilling machine. Please call me
Q: The cause of fracture and why there is no toughness
This question is too broad, see what the casting casting Oh in order to reduce the wayward cast steel, ductile iron, gray iron and white iron, you can choose the material according to their own requirements.
Q: What do you mean by "proofing" in the casting? Do you charge for the proofing?
Proofing refers to making the first sample to confirm to the customer
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!!
Even distribution is a good thing. Generally, the machining allowance of the casting is uneven.If the processing depends on how your processing techniques have been arranged.In the NC milling plane contour machining, when the rough margin is large, how to deal with.1. Return to the foundry, too large margin improvement.2. Then you can spend more time on it.
Q: How to solve casting defect casting?
Different defects, different solutions, some shortcomings, the current domestic level can not be resolved
Q: Shandong foundry, casting small pieces of precision casting
Small foundry in Shandong too much, like many of us in Qingdao, then Dongying Changshun investment casting is a home, they are also casting precision casting equipment, specifically what I recommend that local enterprises, far is not convenient,
Q: The difference between sheet metal and casting parts
Sheet metal refers to the metal sheet (which can be bent straight board, etc.) generally uniform thickness, can obtain the required parts by stamping, molding, welding, splicing and other processing methods.
