Material Application of Carbide End Mill Cutter
Connect with the Sundi Tools Sales Team
Application of Carbide end mill Cutter
Carbide end mill cutters are versatile tools used in CNC machines, engraving machines, and standard milling machines to process heat-treated hard and moderately complex materials. Their hardness usually ranges from HRA93-97, almost as hard as diamonds, which makes them durable and brittle for specific applications. They are also not annealed, making them suitable for a wide range of jobs.

Step 1: Analysis And Design
-
Step 1: Analysis And Design
By thoroughly communicating with our customers and gaining a deeper understanding of their requirements, including accuracy, roughness, and tool lifespan, we can fabricate high-quality carbide milling tools tailored to specific applications.
-
Step 2: Suitable Material Selection
-
Step 2: Suitable Material Selection
We carefully select tungsten carbide rods with varying specifications and performance characteristics based on their intended uses. Our shank diameter tolerance is 0/-0.005mm, reducing vibrations during high-speed cutting.
-
Step 3:Produced by Walter
-
Step 3:Produced by Walter
We use Walter machines for both cutting tool production and re-grinding, and they perform excellently in terms of increasing efficiency. The Walter machine body has a high deadweight and rigidity, that effectively reduces vibration impact and ensures high grinding accuracy. With a stock of 24 grinding wheels, our machines can handle complex geometry structures and large-scale milling cutter production.
-
Step 4: Measure
-
Step 4: Measure
After the completion of carbide end mill production, we conduct a comprehensive test on each tool using Zoller equipment to measure every diameter, angle, and arc. All tools must pass the program's checks before they are sent to our QC department.
-
Step 5: Coating
-
Step 5: Coating
Coating is a chemical and thermal barrier that reduces diffusion and chemical reactions between the tool and the workpiece, thus reducing matrix wear. End mills that undergo coating have many advantages, including high surface hardness, good wear resistance, stable chemical properties, heat and oxidation resistance, low friction coefficient, and low thermal conductivity characteristics. Coated end mills have a cutting life increased by 3-5 times more than an uncoated tool, increased cutting speed by 20%-70%, improved processing accuracy by 0.5-1 level, and reduced total cost by 20%-50%.

Step 6: Package and Delivery
Before packaging and shipping, our expert quality control team tests the tools for dimensions and surface finish to ensure they meet our high standards.
troubles shooting
Sometimes, we are encountering the problems when using the solid inserts, the following are the typical situations that you may face
cutting blade borken

Recycle and Regeneration of Carbide End Mills
Recycle with Re-grinding and Coating
We don’t just offer high-efficiency carbide end mills, we also provide recycling services through re-grinding and coating to reduce tooling costs. Normally, the grinding process only uses 20-30% of new tools but can increase the tool’s working life by over 70%. The proper coating also extends the tool’s life.
Regeneration and Coating
Are you concerned that old tools may no longer work with updated production processes due to changes in dimensions?
We offer regeneration services that update the diameter, shapes, and applications of tools to ensure compatibility with new production processes. The proper coating also extends the tool’s life.
