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!!
Personal advice:Because of the large margin, your outline is easy to guarantee;So the key is to consider the assembly and aesthetics of the casting. You have to find the machining criteria;Rough the datum so that it can be machined;After the outline, turn back to the finishing line.If the casting requirement is not high, the benchmark can be directly processed; (not recommended)Over
Q:What are the effects of stiffeners on castings, or on welded parts (for 2 tons or less), casting or weldments on stiffeners?
3, weight: if reinforcement in products, casting weight is generally greater than the welding parts (the internal organizational structure and mode of production determines the mechanical properties of materials, so it determines the weight of the product), considering the cost of transportation, certain priority structure.
Q:How can the casting be free of trachoma?
2, pouring temperature should be enough, otherwise the sand can not float up;
Q:What reason is the bronze statue choking fire?
The casting process in boiling phenomenon, is the setting of the exhaust hole positioner position or number is not reasonable, the air cavity can not be discharged, overwhelmed by a material inlet, reflux, change mould, sincerely help you look forward to adopt,
Q:Heat treatment process and purpose of casting parts
Methods: artificial aging or natural aging (also called normalization) treatment.Artificial aging: heating to 2-3 Baidu, it is best to apply mechanical vibration, and maintain a period of time.
Q:What are the casting parts used to test shrinkage holes?
3 fluorescent magnetic powder, this method can also be found in part.
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:Explain the heat treatment effect of casting parts, forging parts and welding parts
Good welding of low carbon steel (alloy), probably because the weld workpiece rigidity, fast cooling, the weld internal crystallization of brittle microstructure (martensite), so after welding or welding process welding using self heat, reasonable arrangement of weld, welding seam and heat affected zone heat treatment. The welding heat treatment is often used to preheat before welding, after welding withasbestos cloth covering slow cooling annealing, reach the purpose, its main function is to reduce the internal stress, improve the weld microstructure of martensite formation, reduce brittle tendency, preventing welding cracks.
Q:Why does the surface of stainless steel casting mirror mirror ripple?
The surface can be improved by a little more than Xiasha
Q:What do you mean by "proofing" in the casting? Do you charge for the proofing?
Die die must charge, wood cheap, expensive aluminum mold
