Micro grain for hrc45-hrc65 4- fast delivery and good price Speciafications Chemical composition: 8%-10%co-wc Physical and machinal properties: density: 14.40-14.65g/cm3 hardness: 91-93 hra flexural strength: 3200-4000n/mm2 Organizational structure: wc mean grain size: 0.5-0.6um Corresponds to international standards: k20-k30, k20-k40 Suitable for: machining of cast iron, nonferrous alloy, nonferrous metals, fireproof alloy, titanium alloy, alloy steel, carbon steel and other non-metallic. It has suitable for finishing processing the grooves and side. Meanwhile, it can be processing in high speed and high efficiency which the material hrc>60 The helix angle of the aluminum endmill is divided into 45 degree helix angle and 55 degree helix angle. The 45 degree helix angle is usually called double ligament. The 55 degree helix angle is usually called ligament. Double ligament aluminum end mill more commonly used, more rigid, single ligament aluminum end mill is more sharp, less rigid and double-edged with aluminum end mill nose end mill with r0.5 and r1, generally no special indication on the default is r0.5, r0.5 round nose mill is also more commonly used flat end mill has two edges and four blades, four blade more commonly used, generally no special instructions, the default for the four blade flat end mill aluminum end mill is also divided into three blades and two blade, no special instructions, but also the default is the three-edged. Two-edged aluminum blade is smoother.
