How to choose ball nose milling cutter, square milling cutter and Corner radius milling cutter?
2021-12-06
Considering the influence of factors such as cutting efficiency, tool life, and workpiece shape, it is basically impossible to complete all processing with only one tool. The most commonly used tools can be divided into the following three categories:
(1) Ball nose end mill:
•Material: Ultra-fine tungsten steel
• Number of blades: 2 blades
•Helix angle 35°
•Unique arc clearance angle design
•Suitable for steel cast iron with hardness below HRC50°, alloy steel with high toughness
•material
•Red-shaped machining knife, with a sharp cutting surface on the edge of the knife, which can easily cut any workpiece. Smooth chip evacuation, long tool life and high precision
• A good choice for high-speed machining tools
• Adapt to cutting materials: A3, S45c, S50c, 40Cr, 42CrMo, 20Cr, Cr12, H13, NAK80, 718 and other carbon structural steels, alloy structural steels, cast steel, cast iron, die steel, etc.
(2) Square milling cutter:
•Material: Ultra-fine tungsten steel
• Number of blades: 4 blades
•Helix angle 35°
•Unique arc clearance angle design
•Suitable for steel, cast iron and alloy steel with high hardness below HRC55℃
•The closer the cutting edge is to the mirror surface, the smoother the cutting edge, smooth chip removal, long tool life and good precision
• A good choice for high-speed machining tools
• Adapt to cutting materials: A3, S45c, S50c, 40Cr, 42CrMo, 20Cr, Cr12, H13, NAK80, 718 and other carbon structural steels, alloy structural steels, die steels, etc.
(3) Corner radius end mill:
•Material: Ultra-fine tungsten steel
• Number of blades: 4 blades
•Helix angle 35°
•Unique arc clearance angle
•Suitable for steel, cast iron, alloy steel, high toughness materials with hardness below HRC50°
•The closer the blade is to the mirror surface, the smoother the blade, the smoother chip removal, the longer the tool life, and the better accuracy
• A good choice for high-speed machining tools
• Adapt to cutting materials: A3, S45c, S50C, 40Cr, 42CrMo, 20Cr, Cr12, H13, NAK80, 718 and other carbon structural steels, alloy structural steels, cast steel, cast iron, die steel, etc.
