7075-T6 is aluminum alloy. 7075 aluminum is a mix of 4 different materials: aluminum, 5.6% to 6.1% zinc, 2.1% to 2.5% magnesium and 1.2% to 1.6% copper.
6061 aluminum is an alloy mixed with many other elements. In addition to aluminum, people can also find silicon, iron, copper, manganese, magnesium, chromium, zinc and titanium. Although most of them only account for 0.04% to 0.8%, of which aluminum accounts for about 94%, they still play an important role in the manufacture of strong materials.
Aluminum itself is very soft, easy to bend, and will not bend back to its original state. There are multiple aluminum contents starting from 1100, which is the softest, non-heat treatable and cannot be machined. 7075 is the hardest and can be heat treated and processed. This is why it can be used on Anebon products, because heat treatment makes it stronger, and CNC machining is one of the most common methods for making metal blocks into products such as rods.
According to various drawing requirements. Anebon has many customers’ products that require EDM.
Features of Electrical Discharge Machining:
1) Any conductive material can be processed. The material removal in EDM is realized by the electric heating effect during discharge, and the machinability of the material mainly depends on the electrical conductivity and thermal characteristics of the material.
2) Suitable for processing low-rigidity workpieces and micro processing. Because the shape of the tool electrode can be copied to the workpiece, it is particularly suitable for processing workpieces with complex surfaces.
3) The surface of EDM is composed of numerous small pits and hard convex edges. Its hardness is higher than that of machined surface, and it is helpful to protect lubricating oil. Under the same surface roughness, its surface lubricity and wear resistance are also better than mechanical The machined surface is good, especially suitable for mold manufacturing.
4) However, the speed of EDM is generally slow.
