Component Specifications

Definition
Cutting blades/edges are specialized components mounted on fleshing cylinders in leather processing machinery, designed to remove subcutaneous tissue, fat, and residual flesh from animal hides with controlled depth and precision. These blades feature engineered cutting geometries and material properties optimized for continuous operation in wet, abrasive environments typical of leather production facilities.
Working Principle
The cutting blades operate through rotational motion of the fleshing cylinder against the hide surface. As the cylinder rotates at controlled speeds (typically 200-600 RPM), the blades engage the hide at a precise angle (15-30 degrees) and depth (0.5-3.0 mm). The cutting action combines shearing forces with controlled compression, removing unwanted tissue while preserving the grain layer. Blade geometry (rake angle, clearance angle, edge radius) determines cutting efficiency, heat generation, and hide surface quality.
Materials
High-carbon tool steel (AISI D2, AISI M2) or tungsten carbide with hardness 58-62 HRC for steel, 88-92 HRA for carbide. Surface treatments include chromium plating (3-5 μm) or titanium nitride coating (2-4 μm) for corrosion and wear resistance. Blade bodies typically use martensitic stainless steel (AISI 420) for structural integrity.

Frequently Asked Questions

How often should fleshing cylinder blades be sharpened?

Blades typically require sharpening every 40-80 operating hours, depending on hide type, processing volume, and material hardness. Regular inspection for edge dullness, increased cutting resistance, or irregular hide surfaces indicates sharpening is needed.

What are the signs of blade wear requiring replacement?

Significant edge chipping (>0.5 mm), visible cracks, reduced cutting width below 80% of original dimension, inability to maintain cutting depth consistency (±0.2 mm), or corrosion penetrating the substrate material indicate replacement is necessary.

Can blades from different manufacturers be used interchangeably?

Interchangeability depends on exact mounting dimensions, hole patterns, and blade geometry. While some standardized blades are interchangeable, always verify compatibility with specific fleshing cylinder models and consult manufacturer specifications.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
