How to Check the "Cutting Edge" After a Tungsten Carbide Blades are Made
I. What Tools or equipment Are Used for Inspection?
1. "Extension of the Eyes" - Optical Magnifiers:
Tools: Bench magnifiers, illuminated magnifiers, stereomicroscopes.
What they're for: This is the most common, first-step inspection. Just like using a magnifying glass to examine an antique, it magnifies the cutting edge several times to several dozen times to check for obvious "wounds" on a macro level.
2."Precision Ruler" - Profilometer/Surface Roughness Tester:
Tools: Specialized tool profilometers (with a precision probe).
What they're for: This one is impressive. It doesn't rely on sight. Instead, an ultra-fine probe gently traces along the cutting edge, mapping it out like drawing a map, and generates a precise computer image of the edge's exact shape and smoothness. Whether the rake angle, clearance angle, and edge radius meet the design specifications is revealed instantly.
3. "Super Microscope" - Electron Microscope:
Tools: Scanning Electron Microscope (SEM).
What they're for: Used when you need to "solve a mystery," to find extremely tiny (nanoscale) defects or coating issues. It sees in extreme detail, revealing the microscopic world invisible to ordinary microscopes.
II. What Possible Flaws We should pay attention to?During inspection, just like looking for smudges on a face, focus mainly on these types of "flaws":
1. Chips/Edge Breaks:
They look like: Small, irregular notches on the cutting edge, as if chipped off by a tiny stone. This is the most obvious defect.
Why it is not good: They will leave raised marks or scratches on the workpiece surface during machining and cause the tool itself to degrade rapidly.
2. Micro-chipping/Serrated Edge:
What they are: Under the microscope, the edge appears uneven, like tiny serrations. Less obvious than large chips, but very common.
Why they're bad: Affects cutting sharpness and finish quality, accelerating tool wear.
3. Coating Defects:
They shows: Tools usually have a super-hard coating (like non-stick pan coating). Defects may include peeling, bubbling, uneven color, or incomplete coverage (exposing the yellowish tungsten carbide underneath).
Why they sucks: The coating is the "protective suit." Areas with defects will wear out first, causing the tool to fail prematurely.
4. Uneven Edge/ Burrs:
What they look like: The edge radius or chamfer is uneven-wider in some spots, narrower in others; or there are tiny material overhangs (burrs).
Why it bad: Affects the stability of cutting forces and chip evacuation, reducing machining precision.
5. Cracks:
What they look like: Hairline lines appearing on or near the cutting edge. This is a very dangerous defect.
Why they're bad: Under cutting forces, cracks can easily propagate, leading to sudden tool breakage, which is very hazardous.
