6，Material selection principles

Thick plates: High toughness materials such as Cr12MoV and 6CrW2Si are preferred.

Thin sheet metal: mainly based on wear resistance (such as hard alloy, high-speed steel).

High precision scenario: It is necessary to combine precision grinding technology, and the recommended material is powder metallurgy high-speed steel or SKD-11.

1.Slitting and Cutting of Metal Sheets

General metal material processing: The slitting disc cutter is widely used for slitting processing of metal thin plates such as stainless steel, aluminum plates, and copper plates. High precision cutting is achieved through the longitudinal engagement of the upper and lower blades, meeting the specification requirements of building curtain walls, automotive bodies, and other components.

In the cutting of cold-rolled steel plates, hot-rolled steel plates, and pickled steel plates, the slitting disc cutter made of hard alloy or high-speed steel material can ensure a smooth cut, reduce material loss, and improve the yield of finished products.

High precision specification control: For materials such as silicon steel sheets and tinplate that require strict dimensional accuracy, high-precision slitting disc cutters with a thickness tolerance of ± 0.0005mm and a flatness tolerance of 0.001mm are required to meet the production standards of core components such as transformers and motors.

2.High Strength Material Processing in the Metallurgical Industry

Hot rolled and cold-rolled steel strip processing: The slitting disc cutter is used in the slitting production line of hot-rolled steel strip, which needs to withstand high temperature environment and high-strength shear force. The material is mostly Cr12MoV, SKD and other alloy tool steels, and the hardness and wear resistance are improved through vacuum heat treatment.

In the cutting of cold-rolled steel strip, the blade needs to be matched with hydraulic nuts and other devices to achieve tension control, avoiding deformation or edge burrs of the steel strip.

Nonferrous metal processing: When cutting non-ferrous metals such as aluminum strips and copper strips, the slitting disc cutter needs to have excellent anti adhesion and sharp edge. Hard alloy blades can effectively reduce material surface scratches and deformation.

3.Application of Special Materials and Complex Working Conditions

Stainless steel and corrosion-resistant materials: Special material blades such as LD and H13K are required for cutting stainless steel plates to solve the cutting problem of high hardness materials. They are suitable for corrosion-resistant scenarios such as chemical equipment and food machinery.

The surface of the slitting blade is treated with blackening to enhance its rust prevention performance and adapt to humid or corrosive environments.

Silicon steel and high-precision strip: The cutting of silicon steel sheets relies on a disc cutter with ultra precision flat grinding technology to ensure thickness and flatness tolerances ≤ 0.003mm, meeting the production needs of precision components such as motor cores.

4.Intelligent and Efficient Production Scenarios

Integration of automated slitting equipment:

The fully automatic longitudinal cutting line is equipped with a slitting disc knife and an intelligent cutting system, which can quickly adjust the slitting width to meet the needs of multiple varieties and small batch production, and increase efficiency by 20% -40%.

The turret type slitting device uses a rotating mechanism to replace blades offline, reducing downtime and supporting quick switching of process specifications.

Heavy duty and high-speed cutting scenarios

The high-speed wire cutting adopts Cr8 steel or high-speed steel blades, combined with personalized heat treatment technology, which can withstand the high temperature and impact load of wire cutting.

5.Industry Adaptation and Typical Applications

Automobile manufacturing: Cut steel plates are used for structural components such as the body and chassis, requiring blades to have both high precision and long lifespan.

Home appliance industry: The slitting of metal shells for refrigerators and washing machines requires strict control of burrs and dimensional errors, and is suitable for fully automatic slitting production lines.

Packaging and Electronics: Galvanized sheet and tinplate are cut and used for food cans and electronic component casings, relying on the wear resistance and stability of hard alloy blades.
