American Cutting Edge (ACE, Miamisburg, Ohio, U.S.), a division of CB Manufacturing & Sales Co. Inc., is a supplier of machine knives and industrial razor blades with the goal of removing industrial cutting challenges.

The company manufactures fiber chopping blades. Used in fiberglass cutting machines, the cutting implements are well suited to cutting reinforcement fibers and fiberglass to various industry standards, as well as custom lengths, to be used in fiber, textile and composites industries.

ACE’s staple fiber blades include:

• Mark IV and Mark V blades: Primarily used in tow cutting and fiber chopping
• Krupp blades: Used in finer chopping applications
• Staple blades: Offered in two standard sizes and used for fiber chopping
• Chopper gun blades: Use to chop and spray fiberglass mixed with resin
• Hook blades: Its ability to protect an application’s underlayment makes the blades suitable for textiles, roofing and flooring
• Pierret compatible knives: Applied to recycled fiber materials

Blades come in various materials and coatings such as stainless steels (420 and 440 series stainless for wet chop applications), carbon steel, tungsten carbide, zirconia ceramic, titanium nitride (TiN), titanium carbide (TiC) and ceramic.

Custom blades to customer specifications are also possible, particularly as many off-the-shelf fiber chopping machines are custom-built for their exact material application.
