The radius of the cutting wheel plays a crucial role in its selection and use. Understanding the main factors affecting the radius of the cutting wheel is essential for proper selection and use of the wheel. A detailed analysis is presented below and recommended models and parameters are provided to provide valuable references to readers.
Basic Elements for Selecting the Cutting Wheel
1.Type of Material
The choice of cutting wheel depends first on the type of material to be cut. Different materials require different types of abrasives. For example, steel typically uses aluminum oxide cutting wheels, while stainless steel and non-ferrous metals such as aluminum require zirconium alumina or silicon carbide cutting wheels. The hardness and characteristics of the material determine the type of cutting wheel, as an inappropriate choice can result in low cutting efficiency or even damage to the cutting wheel and the material.
2.Hardness and Toughness
The hardness and toughness of the cutting wheel are also determining factors. A cutting wheel that is too hard can fracture when cutting hard materials, while a wheel with low toughness wears out quickly when cutting soft materials. Therefore, it is necessary to select an appropriate cutting wheel according to the hardness of the material. For example, when cutting cast iron, a harder cutting wheel is needed, while for cutting soft materials such as copper or aluminum, a cutting wheel with higher toughness is required.
3.Speed and Power
The speed and power of the machine directly influence the choice of cutting wheel. High-speed machines need high-strength cutting wheels to prevent breakage, while low-power machines need thinner cutting wheels to reduce cutting resistance. Different machines have different speed and power requirements, so when selecting a cutting wheel, it must be ensured that it can withstand the working conditions of the machine.
4.Cutting Speed
Cutting speed is also an important factor in the selection of cutting wheel. Higher cutting speed can increase work efficiency, but it also accelerates the wear of the cutting wheel. Depending on the specific needs of the work, cutting wheels of different speed levels can be selected.

|---|---|---|---|---|
| Steel | Aluminum Oxide | High | Norton Gemini RightCut | 4.5 |
| Stainless steel | Zirconia Alumina (Zirconia Alumina) | Average | Weiler Tiger Zircon | 6 |
| Aluminum | Silicon Carbide | Low | Grainger GatorBlade | 5 |
| Copper | Aluminum Oxide | Low | Norton BlueFire | 4.5 |
| Cast iron | Mixed Abrasives | High | Weiler Wolverine | 6 |
Specific Factors in Selecting Cutting Wheels
1.Cutting Depth
Cutting depth is an important factor that determines the radius of the cutting wheel. The larger the diameter of the cutting wheel, the greater the cutting depth. For example, a 4.5-inch cutting wheel can typically cut up to 1.25 inches deep, while a 6-inch cutting wheel can cut up to 2 inches deep. When selecting a cutting wheel, it is necessary to determine its diameter based on the required cutting depth.
2.Machine Specifications
Different cutting machines have different cutting wheel diameter requirements. Make sure that the selected cutting wheel is compatible with the machine's specifications. For example, a 4-inch angle grinder is usually equipped with 4.5-inch or smaller cutting wheels, while larger benchtop cutting machines may be equipped with 6-inch or even larger cutting wheels. When selecting a cutting wheel, carefully read the machine's manual to ensure that the cutting wheel diameter is compatible with the machine.
3.Application Scenario
Different application scenarios also have different requirements for cutting wheels. For example, a construction site needs efficient and fast cutting tools, so it is recommended to use cutting wheels with large diameter and high speed; while in precise processing environments, cutting wheels with higher precision and smaller diameter are needed. In addition, when selecting a cutting wheel, it is also necessary to consider the working environment, such as whether a waterproof or dustproof cutting wheel is needed, etc.
4.Cutting Method
The cutting method includes dry cutting and wet cutting. Wet cutting can reduce the heat and dust generated during cutting, thereby extending the life of the cutting wheel. When selecting a cutting wheel for wet cutting, make sure it is suitable for the machine and material used.Recommended Models and Parameters of Cutting Wheels
