1. The substrate must be cleaned, sprayed with a pair of double-section anti-rust primer, and sprayed with corrugated paint after drying.
2. The application viscosity is generally 35~60 seconds (coating 4 cups).
3, the paint is too thin, easy to expose the bottom, pinholes.
4. The distance between the spray gun and the substrate is too far, the ripple is small, and the ripple is large.
5, spray the first time as much as possible to cover the substrate, * distance can be far, the amount of oil can be small.
6. When spraying the second time, the interval is about 10 minutes, the oil output is slightly larger, and the distance is moderate. Walk * evenly and shape once.
7, the situation of the bottom, you can add one or two drops of anti-oil agent.
(1) Diamond pen dressing grinding wheel: According to the size of diamond particles and their distribution in the pen, diamond pens can be divided into several types, such as chain and powder. The alloy with strong bonding force is used as the bonding agent, so the diamond grinding wheel particles are not easy to fall off during use, so there is no need to repair the grinding process.
(2) Grinding wheel dressing by rolling method: Diamond grinding wheel dressing by rolling method. Grinding wheel drives the rolling wheel at the speed of 1~2m/s by reducing the speed
Made of, carbide or abrasive) rotary. The pressure of rolling wheel applied to grinding wheel is about 3~5MPa, grinding the surface of diamond grinding wheel
Make the abrasive particles fall off. The grinding wheel dressing by rolling method has better cutting performance and lower cost, but the surface roughness of the grinding part is rougher and rolling
Damage, short life, easy loss of precision. Therefore, this dressing method is mainly used for forming grinding with small batch size and low precision.
Green silicon carbide or ceramic white corundum is used for dressing. Dressing ring is the first choice for dressing diamond grinding wheel or CBN grinding wheel. It is sharp in dressing, not easy to remove sand and has high dressing efficiency.
