As a senior supplier in the circular blade industry, "Can circular blades cut metal?" is a frequently asked question, and the answer is clear: Yes! However, it is necessary to choose the right blade and use the correct method; otherwise, the blade will be worn out and the construction period will be delayed. The following are the core key points.
Ⅰ. Choose the right blade: Different metals match exclusive models
There is no one-size-fits-all circular blade. Only precise matching can balance effectiveness and service life. Universal circular blades are suitable for cutting thin plates, with fine and sharp edges, resulting in flat and burr-free cuts, making them ideal for light industry fields with high precision requirements. For cutting thick materials or high-hardness metals such as stainless steel and hard aluminum alloys, special circular blades made of tool steel or tungsten carbide should be used. These blades have high hardness and strong wear resistance, and can withstand high-pressure cutting impacts.
II. Cutting Principle: Not Only Sharpness, but More on Shearing Force
Cutting metal with a circular blade is not "hard cutting" but rather utilizes shearing force: when the blade rotates at high speed, the edge concentrates the force on an extremely small contact surface, breaking the binding force of metal molecules and achieving rapid separation.
Ⅲ. Key Factors: 3 Points Determine the Success or Failure of Cutting
1. Rotational speed: It needs to be adjusted according to the thickness and material of the metal. If it is too low, it is easy to wear the blade and make the cut rough; if it is too high, it is easy to generate heat and cause metal deformation.
2. Feed speed: If it is too fast, it is easy to cause edge chipping and cut skew; if it is too slow, the efficiency is low. It is necessary to find a balance between high efficiency and stability.
3. Lubrication: It reduces friction, cools down and removes chips, avoids damage to the blade, and improves the smoothness of the cut.
Ⅳ Application Scenarios: Rigid Demands Across Multiple Industries
Circular blades are widely used in industries such as metal pipe manufacturing, aerospace, hardware manufacturing, home appliance processing, and mechanical parts production, and can be adapted for cutting thin and thick metals.
V. Selection Summary: Even Beginners Can Get Started
For thin and soft metals, choose general-purpose round blades; for thick and hard metals, select special hard-edge round blades. By matching them with appropriate rotation speed, feed rate, and lubricant, efficient and stable cutting can be achieved.
