Hitachi's ball end mills for metal mold finishing
Aluminum Color Coated Sheet is Aluminum Sheet with color coated on one side or two sides.It is widely used in construction areas.It is light in the weight and easy to be recycled.Also with the color coating,the surface is good looking and has longer life in corrosion resistance.Aluminum Color Coated Sheet has more advantage as follows:
1. Easy to process. Colored Aluminum Sheets,Painted Aluminum Sheets,Decorative Aluminum Sheet,Coloured Aluminium Sheet Trumony Aluminum Limited , https://www.szaluminumsheets.com
This spherical end mill includes re-grindable G-type and vertical wall W models, priced from 5895 yen to 11,130 yen.
Among them, the G-shape shortens the straight-line cutting edge of the outer peripheral portion, and in the chisel-edge portion, the "GF edge type" suitable for castings and raw materials and the "GH edge type" suitable for high hardness are used. On the special base metal, the layered wear layer based on PVD (Physical Evaporation Method), named “ACS†and “ATHâ€, is used to increase its adhesion strength, film hardness, and oxidation temperature.
The use of "ACS" and "ATH" coatings extends the blade's processing life in a smooth shape. The composition of the ACS coating starts from the side of the base metal and consists of a layer of Al high toughness bonding layer, a wear layer of AlCrSi and TiSi laminated, and a Cr lubricating film. The composition of the ATH coating starts from the side of the base metal and is as follows: a TiAl film, the same abrasion resistant layer as the ACS, and a TiSi heat resistant film.
In addition, the W-type uses an R-type cutting edge with no peripheral straight edge to slow down the high-frequency vibrations generated during vertical wall machining. The chisel edge part has the same GF/GH edge type as the G type, and the coating also uses the ACS/ATH coating.
The results show that the casting aluminum alloy with good casting property or deformation aluminum alloy with good processing plasticity can be obtained by adding certain Ba Au Du element.
2. Good conductivity and thermal conductivity.
The electrical and thermal conductivity of aluminum is second only to silver, copper and gold.
3. The density is small.
The density of aluminum and aluminum alloy is close to 2.7 g / about 1 / 3 of that of iron or copper.
4. High strength.
The strength of aluminum and aluminum alloy is high. The matrix strength can be strengthened by cold working to a certain extent, and some brands of aluminum alloy can also be strengthened by heat treatment.
5. Good corrosion resistance.
The surface of aluminum is easy to produce a dense and firm protective film of Al2O3, which can protect the substrate from corrosion.
