When we talk with our clients who want to buy tungsten carbide knives, not only for tobacco making, including other demanding industries, such as textile slitting, fiber cutting, corrugated board slitting, usually the things we need to confirm, or What to Prepare Before Talking in choosing or custom industrial tungsten carbide blades, are as following:
I. Drawings / Technical Specs
1. Insufficient Homogeneity of WC-Co Powder
Prepare either a drawing or a specification sheet. Include:
Geometry
▶ Outer diameter (OD)
▶ Inner diameter (ID) / bore size
▶ Thickness (T)
▶ Cutting edge angle (if applicable)
▶ Chamfer / bevel details
▶ Tolerances for OD / ID / thickness
▶ Edge type:
flush-ground
double-bevel
single-bevel
hone type
sharpness requirements
Mounting Details
▶ Keyway? (Y/N, dimensions)
▶ Holes? (quantity, location, countersink)
▶ Fit with a specific brand of tobacco machine (e.g., Hauni, GD, Molins)
2. Application Information
This helps us to choose the carbide grade and sintering hardness. we should Prepare:
What material the knife will cut?
Cigarette rod
Filter rod
Tipping paper
Cork paper
Plug wrap
BOPP film
Cutting conditions:
Continuous high-speed? (e.g., 8,000–12,000 rpm for filter knives)
Wet or dry cutting
Expected usage life / performance target
3. Preferred Carbide Grade
If you know what grade you want, please tell
If you know what grade you want, tell them:
YG10X / K10 – common for cigarette/slitting knives
YG12X – tougher, for filter rod processing
Ultra-fine grain carbide – for precision tobacco blades
If you don’t know, they will select according to application — but giving a baseline helps.
4. Surface Finish Requirement
Especially important for tobacco knives:
Ra requirement (e.g., Ra ≤ 0.05 μm)
Polished vs. ground vs. mirror finish
Coatings? (Usually no coating for tobacco; but some need TiN)
5. Your Quality Requirements
We will ask about:
Hardness (e.g., HRA 90–92.5)
Flatness tolerance (e.g., ≤ 0.003 mm)
Parallelism
Concentricity
So there will be a standard,it helps us design and quote accurately.
