1. Types and characteristics of mesh treatment
The cast iron can be divided into: gray melting, white cast iron, forged cast iron, ductile melting, creeping cast iron, alloy cast iron, etc. Among them, gray melting is widely used in the automotive industry, and the automotive industry is a major demand for CNC tools, so that processing factories often have the demand for gray melting treatment.
2. What tools are used to treat ordinary melting?
The ordinary cast iron irons mentioned in this article are gray melting, ductile melting and austenitic melting. Due to the influence of the graphite content of the ductile melting, alloy strawberries economical coated can generally be used for integrated cemented carbide rods.
Ordinary cast iron treatment tools and economic tungsten steel strawberries are able to do so. Second, high -speed steel tools containing cobalt can be used.
3. What tools are used for melting difficult to treat?
Here we will only give examples of cold cast iron. To obtain a cast iron structure of encyclopedia, forming high resistance to hardness and wear. The hard cold melting can be divided into ordinary hard cast iron, nickel-chromium cold fern, high chromium white tin and white chromium-vana.
1) Treatment of the characteristics of the cold hard cast iron
Cold hard cast iron has high hardness, great fragility and great unit cutting force, and its shavings are in a broken fit. Force and cut concentrated heat near the tip, which makes the tool easy to make the tool. Most parts of hard cold melting treatment are whites, with significant and unequal treatment allowances, which increases the difficulty in processing cast iron. Of course, there are currently good solutions for cast iron treatment tools, cast iron strawberries, etc.
2) Selection of cold cast iron treatment tools
It is preferable to choose tool materials with high hardness, good wear resistance and a certain resistance when processing the cold melting. Generally, it is made of fine-grained or ultra-fine ceramic tools or an ultra-fine grain or aluminum that use coatings.
3) Reduction of use for the treatment of cold cast iron strawberries
Carbide cutting tool; at low speed and high supply. V = 9 m / min, the power frequency is generally selected according to the main deviation angle and the knife behind. Select 0.5 mm / R for rough melting treatment and 0.1 ~ 0.4 mm / r for the cast iron finish.
Ceramic tools; The milling generally at high speed is selected, with a coarse and semi-finished cast iron v = 50 ~ 80 m / min, and V = 80 ~ 120 m / min during the finish.
The cast iron treatment tools, such as knife particles, can be rough, semi-finished and finished. If you do not know which milling striker to use for melting, of course, you should choose the YG -type cemented carbide tool when processing cast iron strawberries.
