The time that Tungsten carbide and Cemented carbide end mills can retain their sharpness mainly depends on many factors such as the workpiece material, cutting speed, and feed.
Next, PUWEI will take you to understand how to maintain the sharpness of carbide end cutter!
First: Workpiece materials
When we use Tungsten carbide to process soft materials, the end mills wear more slowly, and we can maintain their sharpness for a longer time.
The expected life of the Hard alloy end mills usually allows us to maintain 5-28 hours of machining time, which depends on the cutting conditions of the carbide end mills.
Carbide end mills in the processing of hard materials, due to the high hardness of the material, the wear of the end mill faster, the expected life is usually 30 minutes -8 hours, especially in the high-speed cutting when the wear increases, thus shortening the life.
Second: Tool Coating
We usually coat Hard alloy end mills with TiN, TiAIN, AICrN, and these coatings improve the wear and oxidation resistance of the tool.
The life of a coated end mill is generally 30%-200% longer than that of an uncoated end mill, depending on the machining conditions.
Finally: cutting speeds and feeds
High-speed cutting will lead to a rapid rise in end mill tool temperature, exacerbating the appearance of wear, excessive feed, easy to lead to tool chipping or rapid passivation, which is also one of the impact on the life of carbide end cutter.
How to extend the life of carbide end mills?
1. Choose high quality coated tools: Puwei carbide end mills are based on your workpiece material to choose the right type of coating to extend the life of carbide end cutter
2. Regular tool sharpening: apply tool sharpening equipment to extend tool life, avoid overload machining, do not excessively increase the depth of cut or feed, through this dimension is also to extend the life of the carbide
3. Optimize tool parameters: You can properly optimize the cutting parameters, reduce the cutting speed and feed of the carbide end mill to reduce wear and extend the life of the carbide end mill.
