Product Description
Tungsten Carbide Circular Slitting Knives
The Carbide Circular Knives are used in a wide variety of applications for their ability to slice through many materials, so, usually the blades are made for these applications are custom sizes. Our Carbide Circular Knives can be supplied up to 400 mm in Diameter with different inner hole diameters, Pin holes, Key Ways, cutting edge shapes and bevel angles . They are precision ground to a high tolerance standard, mirror finish surface and sharp cutting edge. They can be used in high speed cutting, with a high production efficiency and good surface finish.Applications:
Paper industry
Printing industry
Metal industry
Textile industry
Tungsten carbide blade is mainly used for cutting paper in printing industry tungsten carbide knife products require high precision, no glitches, maximum abrasion resistance.
we are using HIP sintered and fine grinding, polishing plating to reduce frictions when cutting, improved the accuracy and speed slitting greatly, tool life extended.

FAQ
Q1. How do you control the quality ?
First control is 100% raw material from WC supplier, 100% inspecting throughout each process.Continuous training for experienced engineers and workers.
Q2. How can I choose the right TC Grade for the carbide products ?
If you can not confirm which TC grade is right for your products, please kindly provide us with your purpose of usage, we would suggest the most suitalbe grade for you.Q3. Why the short working life time of corrugated board knives ?
1.Is the grain size of the grinding wheel proper? Too coarse grain size of grind wheel :make a short working life time of knives.2.Too frequent grinding; the grinding time is too long, or the grinding pressure is too high.
Q4. Why the edge of corrugated boards cut by knives with burr and dent ?
1.Please check the cutting edge of your blades. Is the cutting edge keen enough?2.The corrugated board is too wet.
