Precision Cutting Blade Assembly for Fish Filleting Machines

Product Specifications

Technical details and manufacturing context for Precision Cutting Blade Assembly

Definition

The Precision Cutting Blade Assembly is a critical component of an Industrial Fish Filleting Machine, responsible for executing clean, precise cuts to separate fish fillets from bones and skin with minimal waste. It ensures consistent cutting quality and operational efficiency in high-volume fish processing environments. The assembly typically consists of multiple sharp blades mounted on a rotating or reciprocating mechanism. It operates by applying controlled mechanical force to slice through fish tissue along predetermined paths, guided by the machine's positioning system to achieve uniform fillet thickness and shape. The assembly is available in configurations with blade diameters ranging from 150 to 250 mm, blade thicknesses from 0.8 to 1.2 mm, and cutting speeds from 3000 to 6000 rpm. Positioning accuracy is maintained within ±0.05 mm to ensure consistent fillet thickness. The operating pressure range is 1.0 to 1.6 MPa, and the operating temperature range is -10 to 50 °C. The assembly offers ingress protection ratings from IP54 to IP65 (per IEC 60529) for washdown environments. Blade material is stainless steel grade 1.4116 (per DIN EN 10088-3) for corrosion resistance, with high-carbon steel also available. The weight ranges from 3.5 to 5.0 kg. These values are directory reference ranges and must be verified for the specific model and application with the legal manufacturer or supplier. The assembly is designed for integration into industrial fish processing lines, and its performance depends on proper installation, alignment, and maintenance. Regular inspection of blade sharpness and wear is recommended to maintain cutting quality. The assembly is not a standalone machine; it requires the host machine's control system for operation. Always consult the manufacturer's documentation for detailed specifications and safety guidelines.

Working Principle

The assembly uses a set of sharp blades mounted on a rotating or reciprocating drive. The machine's positioning system guides the blades along predetermined paths, applying controlled mechanical force to slice through fish tissue. The blade speed and feed rate are coordinated to achieve uniform fillet thickness and shape, minimizing waste. The blades are made of stainless steel or high-carbon steel, and their geometry and sharpness are critical for clean cuts. The operating pressure and temperature affect the cutting performance and blade durability. The assembly's ingress protection rating ensures it can withstand washdown conditions. Proper alignment and tensioning of the blades are essential for consistent operation.

Frequently Asked Questions

What materials are used for the blades?

The blades are available in stainless steel grade 1.4116 (per DIN EN 10088-3) for corrosion resistance, and high-carbon steel is also an option. The specific material should be confirmed with the manufacturer for the intended application.

What is the operating pressure range?

The operating pressure range is 1.0 to 1.6 MPa. It is important to verify that the system pressure is within this range to ensure proper cutting performance.

What ingress protection rating does the assembly have?

The assembly offers ingress protection ratings from IP54 to IP65, per IEC 60529. IP65 is suitable for washdown environments. The actual rating depends on the specific configuration and should be confirmed with the supplier.

How does the assembly achieve consistent fillet thickness?

The assembly maintains positioning accuracy within ±0.05 mm, which ensures uniform cutting depth and fillet thickness. The machine's positioning system guides the blades along predetermined paths, and the blade speed and feed rate are coordinated to achieve consistent results.
