Which is better, graphite milling cutter or HSS milling cutter?

Graphite milling cutter is designed for higher hardness of graphite and other materials, high-speed steel milling cutter is more suitable for soft material processing, both have their own characteristics, we need to choose when combined with the processing needs to. So, which one is better? Specific differences and selection direction of Zhongye Da editorial share the following.

First, the core characteristics of the two milling cutters

Graphite milling cutter is often coated with diamond, high hardness, good heat and wear resistance, can extend the service life. Its cutting edge geometry angle is optimized, cutting performance is stronger, higher processing efficiency, but also reduce the time of tool change and the problem of tool marks. Wide range of applications, in addition to graphite, but also processing alloy non-ferrous materials, composite materials, high silica aluminum and other materials with high hardness.

High-speed steel milling cutter with a certain degree of hardness and toughness, can be used to keep the cutting edge sharp, the price is relatively affordable, in durability and efficiency have a better balance between. However, the cutting speed is limited, heat resistance is general, more suitable for processing soft materials such as soft steel, aluminum, brass, etc., not suitable for materials with high hardness.

Second, the choice of recommendations

Look at the processing material, if processing graphite, alloy non-ferrous materials such as high hardness materials, give priority to graphite milling cutter. If processing soft steel, aluminum and other soft materials, high-speed steel milling cutter is a more economical choice.

Look at the machining accuracy, for the higher precision and surface quality requirements of the scene, graphite milling cutter performance is more stable. HSS milling cutters can also ensure a certain degree of precision when processing soft materials, but the stability is slightly inferior.

For cost considerations, graphite milling cutters have a higher unit price, but can reduce overall consumption by improving efficiency and reducing tool change costs. For cost-sensitive and soft material processing scenarios, HSS milling cutters are more suitable.

Zhongye da editorial summary:

Graphite milling cutter and high-speed steel milling cutter has no absolute advantages and disadvantages, the key is whether to adapt to the processing needs. Combined with the type of material, precision requirements and cost budget comprehensive judgment, in order to choose a more suitable milling cutter, to protect the processing quality and efficiency.
