Factors affecting the abrasion resistance of solid carbide milling cutter
 Feb 09, 2022|View:672

At present, the economic environment is stagnant, the industry competition is more and more fierce, the profit space is smaller and smaller, the major industries have entered a period of meager profit. Perhaps in the mold industry, the wear resistance of solid carbide milling cutter is also a concern for management. What are the factors that affect the abrasion resistance of the solid carbide milling cutter?

1. Solid carbide milling cutter materials


The solid carbide milling cutter material is the most fundamental factor to determine the cutting performance of the solid carbide milling cutter. It has a great influence on the processing efficiency, quality, cost, and durability of the solid carbide milling cutter.


The harder the solid carbide milling cutter is, the better its wear resistance, the higher its hardness, and the lower its impact toughness, the easier it is to break. Hardness and toughness are contradictory and a key problem for solid carbide milling cutter manufacturers to solve. How to balance hardness and toughness has been a hard research topic for many manufacturers.


2. Solid carbide milling cutter geometry


The solid carbide milling cutter can reduce the vibration of the solid carbide cutter by choosing the proper geometry, and the solid carbide milling cutter is less prone to breakage.

3. Solid carbide milling cutter


Choosing the right groove shape helps improve the wear resistance of the solid carbide milling cutter. The most common one on the market right now is the point cutter, which is suitable for machine tools with better performance. If the performance of the machine tool is poor, it is better to use a larger cutter with a rounded angle. The solid carbide cutter is sharper, and the stainless steel cutter is suitable for this solid carbide cutter.


4. Solid carbide milling cutter coating


The coated solid carbide milling cutter features high surface hardness, good wear resistance, stable chemical properties, heat and oxidation resistance, low friction factor, and low thermal conductivity, compared with the uncoated solid carbide milling cutter, the life of a solid carbide milling cutter is increased by 3 ~ 5 times, the cutting speed is increased by 20% ~ 70%, the machining accuracy is increased by 0.5 ~ 1 grade, and the cost of the solid carbide milling cutter is reduced by 20% ~ 50% .


However, different substrates are suitable for different coatings, some are suitable for physical coatings, some are suitable for chemical coatings, and physical coatings are more widely used than chemical coatings.
