Blade Edge: Width 10-100 mm, Thickness 2-10 mm

Component Specifications

Definition

The blade edge is the critical cutting component of a skimming arm/blade assembly, designed to precisely remove thin layers of material from workpieces during machining, finishing, or surface preparation operations. It features specific geometry, sharpness, and hardness to ensure clean cuts with minimal deformation or burr formation.

Working Principle

Operates on the principle of shear cutting, where the sharp edge applies concentrated force to exceed the material's shear strength, separating material along a defined path. In skimming applications, it typically moves linearly or rotationally to shave off uniform layers.

Materials

High-speed steel (HSS), tungsten carbide, ceramic composites, or coated tool steels (e.g., TiN, TiAlN coatings). Hardness: 58-65 HRC for steel, 85-92 HRA for carbide.

Frequently Asked Questions

What factors affect blade edge longevity?

Material hardness, cutting speed, feed rate, coolant use, and workpiece material abrasiveness directly impact wear and edge life.

How often should blade edges be inspected?

Inspect every 8-16 hours of operation for wear, chipping, or dullness, depending on application severity.

Can blade edges be re-sharpened?

Yes, if made of HSS or tool steel, using precision grinding; carbide edges are typically replaced due to brittleness.
