Features

 

Low Cutting Cost

The teeth are made of high-speed steel to absorb wear, while the backing material does not participate in cutting, concentrating wear on the tooth tip area; this allows for more cutting meters with the same blade length.

 

High Efficiency
The backing material withstands cyclic bending stress around the wheel (the continuous bending radius is determined by the wheel diameter), while the teeth withstand cutting impact stress; these two types of stress do not superimpose in the same material.

 

Wide Compatibility
The tooth hardness ranges from low-carbon steel to medium-alloy steel, and the backing material provides structural load-bearing capacity; the same model can be used simultaneously for solid bars, profiles, and thin-walled parts.

 

Applications

 

Machinery Manufacturing Industry: Used for cutting steel and alloy materials to provide basic dimensions for subsequent machining.

Energy and Power Industry: Used for cutting pipes and structural components during equipment maintenance to meet on-site dimensional adjustment needs.

Research and Testing Institutions: Used for preparing metal samples to ensure material dimensions meet testing standards.

Metal Processing Industry: Used for continuous cutting in mass production to bring different materials to preset specifications.

 

FAQ

 

Q: How to determine if the current saw blade is suitable for the material being cut?

A: Observe the cutting process for persistent vibration, rough cut surface, or limited feed. This usually corresponds to tooth wear or tooth pitch mismatch. The saw blade type or tooth pitch should be reselected based on the material hardness and cross-section.

Q: Why is a bimetallic structure still needed for metal cutting?

A: Metal cutting involves two types of loads: tooth wear and overall strip bending. A bimetallic structure distributes these two loads to different materials, preventing a single material from failing under both stresses simultaneously.

Q: How to reduce tooth breakage or strip breakage during use?

A: Control the feed speed to ensure that the force on a single tooth does not exceed its load-bearing capacity. Reduce the feed when the cutting cross-section changes (e.g., from hollow to solid) to reduce concentrated impact loads.
