How to prevent deformation during slow wire processing

 Slow-moving wire processing is a very exquisite and exquisite craft, and sufficient preparations need to be made, so that the processed products can be more quality. The slow-moving wire processing technology has a wide range of applications and is a must in our industries. If you want to do better with less technology, you must master all aspects of the processing knowledge. For example, the most common thing is the deformation during processing.  How can we solve it How to prevent deformation during slow wire processing Speaking of slow wire processing, it uses continuously moving fine metal wires as electrodes. Pulse spark discharge is performed on the workpiece, where it generates a high temperature above 6000 degrees. Moreover, if it wants to improve its quality problems and prevent its deformation, it can firstly start from the following aspects. 1. To prevent deformation, it is impossible for the material to have no internal stress. In particular, the internal stress of the que

What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

What are the Factors That Affect the Surface Roughness in Precision Part Machining?

What are the factors that affect the surface roughness in machining precision parts?

1, the influence of cutting force and friction.When precision parts processing cutting tool cutting edge rounded corners and in the face of workpiece profile extrusion and friction may cause a plastic deformation of the metal material, which leads to the existing residual area distorted or deeper grooves, at this point, the increased surface roughness and machining brittle material cutting scrap into broken particles, and the surface of the processed often shows traces of particles collapses,Leaving many pits and roughening the surface.

 

2, the impact of the accumulation of clastic tumors.When a cutting tool is cutting plastic at a certain speed, some small particles on the chip will adhere to the tip of the front cutter face, forming the accumulation edge of high hardness, which can replace the front cutter face and cutting edge cutting.

When the friction between the chip and the stacking edge is greater than the cold welding strength between the stacking edge and the front cutter face, or when it is impacted or vibrated, the stacking edge will fall off, so that the new-up edge will be gradually generated in the future.The formation, growth and shedding of the stacking edges will seriously affect the surface roughness of the parts.

 

3. Influence of scaly spines.In the cutting process, due to the friction and cold welding of the chip on the cutting surface during precision parts processing, the chip will regularly stay on the front cutter surface, thereby squeezing the newly processed surface.In severe cases, the surface can tear.Scales form on the surface, making the surface rough and uneven.

 

Due to the effects of the above physical factors on the roughness, in order to reduce the surface roughness, in addition to reducing the plastic deformation caused by the cutting force, the accumulation of tumors and scales during the machining of precision parts should be avoided.

 

The main process measures are: choose the cutting speed which is not easy to produce the accumulation edge and the prick to improve the cutting performance of the material to choose the cutting fluid correctly.
