Products ：Industrial alloy round blades are indispensable precision cutting components on packaging machines. They are usually made of materials such as alloy tool steel or high-speed steel. Their shape is disc-like, with a round hole in the middle to facilitate installation and fixation on the equipment.

These blades mainly perform efficient striping or edge trimming operations on various packaging materials such as paper, film, metal foil, and tape through cutting or extrusion methods. Their core task is to ensure that the width of the cut packaging materials is accurate, the edges are smooth and flat without burrs, in order to meet the high-speed automation requirements of the subsequent packaging process and the appearance quality of the final product.

Product Name: Industrial alloy round blades

Material:

Alloy tool steel: Such as 9CrSi, Cr12MoV (corresponding to Japanese SKD-11). It has good toughness and certain wear resistance, with a high cost-performance ratio, and is a common choice for many cutting applications.
High-speed steel (HSS): For example, W6Mo5Cr4V2 (corresponding to M2 in the US). It has higher red hardness and wear resistance, and is suitable for high-speed cutting or processing of materials with slightly greater difficulty.

Size: The sizes of industrial alloy round blades vary. The common diameters range from 300mm to 1000mm; the thickness range: the thickness is usually between 0.5mm and 300mm; custom orders can be made upon request.

Type: Heat treatment: processes such as quenching + tempering; Precision machining and grinding; Coating treatment. Some of the blades will be coated with PVD (e.g. TiN).

Features:

High hardness and wear resistance: Using high-quality alloy materials (such as Cr12MoV), the blade has high hardness and excellent wear resistance, which can effectively extend the service life and reduce the frequency of replacement.
Precise cutting capability: The blade edge has been precisely ground, making it extremely sharp. This ensures smooth cutting, resulting in flat, smooth cuts without any burrs, meeting the requirements for high-precision slicing.
Corrosion resistance and anti-sticking properties: Some blades will be coated with materials such as Teflon to prevent certain materials (such as those containing sugar, oil, or sticky polymers) from sticking.
High stability: The high-quality blades ensure smooth operation at high speeds, reduce vibrations, and guarantee the quality of the cutting process.

Application Scenario: Industrial alloy round blades are widely used in the packaging industry, covering almost all common packaging materials:

Paper and cardboard: Cutting and trimming of various types of paper such as kraft paper, white board paper, and coated paper.
Plastics and films: Cutting of various plastic films and packaging materials such as BOPP, CPP, PET, PVC, etc.
Metal foil materials: Cutting of precise metal materials such as aluminum foil and copper foil.
Other materials: Cutting of materials such as tape, non-woven fabric, leather, rubber (including PP, PV) etc.

Selection criteria:

Based on the processing material: For cutting ordinary paper or films, cost-effective alloy tool steel (such as 9CrSi) can be chosen; for cutting high-strength or materials with abrasive properties, high-speed steel or hard alloy blades can be considered.
Confirm specifications and accuracy: Based on the model of the packaging machine and the requirements for cutting, determine the key specification dimensions such as the diameter, thickness, and inner hole diameter of the required blades, as well as the corresponding accuracy levels.
Consider non-standard customization: For special materials or unique cutting requirements, we offer custom services based on provided drawings and samples.
