Selecting Carbide Inserts: Types, Coatings, and Production
In modern machining processes, there are numerous types of carbide inserts and coatings. Do various CNC inserts have their own advantages? This depends on the type of insert. Only by finding the carbide insert suitable for the processing material during machining can continuous processing be achieved. Therefore, today we will learn how to select carbide inserts and their types.
Types of Carbide Machining Inserts
1 Classification by Geometric Shape
Type | Typical Groove Type | Features | Applicable Scenarios |
|---|---|---|---|
Positive Rake Inserts | C Type, D Type | Light cutting, smooth chip removal | Fine machining, thin-walled parts |
Negative Rake Inserts | T Type, R Type | High cutting edge strength, multiple cutting edge reuse | Heavy-duty rough machining, interrupted cutting |
Forming Inserts | V Type, S Type | Complex contour forming | Mold cavity, surface machining |
Cut-off Inserts | G Type, F Type | Narrow blade design, precise depth of cut control | Groove machining, cut-off operations |
2 Classification by Coating Technology
1. CVD Coating (Chemical Vapor Deposition)
Coating ：TiCN/Al ₂ O ₃ /TiN Multi-layer composite
Advantages High temperature resistance (> 1000℃ ), oxidation resistance
Scenarios High-speed continuous cutting of steel parts
2. PVD Coating (Physical Vapor Deposition)
Coating ： TiAlN 、 CrN 、 DLC etc.
Advantages Smooth surface, low coefficient of friction
Scenarios High-precision machining, viscous materials (aluminum alloy, titanium alloy)
