What are the polishing methods for tungsten steel inner holes in the fluid polishing machine?
Common methods for internal hole polishing of special-shaped tungsten steel:
1. The polishing method of the inner hole of the special-shaped tungsten steel most manufacturers in the tungsten steel polishing, mainly is difficult to polish the special-shaped products, for example, the inner hole is irregular shape, can be filled with cloth in the inner hole, the workpiece fixed, with two people to pull, to product ironing, smoothness for the mirror.
2. The polishing method of tungsten steel with special shape is irregular polishing. Ultrasound polishing is usually used first, and then the polishing paste is added. The polishing machine is used to polish the tungsten steel with mirror surface.
3. The special-shaped tungsten steel regular square polishing method regular square, mostly in the surface grinder processing, can use the grain size diamond grinding wheel polishing. Round polishing of irregular tungsten steel. Round tungsten steel polishing to the mirror can be directly polished by diamond grinding wheels without center grinder.
4. Fluid polishing technology is recommended for inner hole polishing of special-shaped tungsten steel, which is convenient and efficient and has good polishing effect.
What preparations should be made for abrasive flow polishing?
Abrasive flow polishing is the chamfering deburring and mirror polishing of small holes, cross holes, special-shaped holes, surfaces and diamond corners of parts and components with special abrasive. This processing technology can effectively Polish parts concealed parts. The abrasive will transfer the pressure produced by the machine to the parts for grinding, polishing, chamfering, deburring, etc. The abrasive moves up and down, and rubs the surface. General abrasive material, particle size, viscosity can determine the effect of polishing, polishing before what preparation work?
Before polishing the workpiece with abrasive, it is necessary to clean the parts, especially the small hole, narrow groove and precision machining department. Cleaning before machining is to remove granular materials from parts. Large granular materials can clog small holes and even damage the machined surface. So cleaning is particularly important. Fixtures play a fixed role, and can make abrasive to the surface of the parts to be processed, some parts do not need parts as an auxiliary, large-scale mold production needs to be assisted by fixtures, furniture is generally made of alloy, stainless steel, nylon and so on.
