In modern manufacturing, metal structures, building installations, and home DIY, cutting discs are one of the indispensable basic tools. Cutting efficiency, cut quality, and tool life are often closely related to the proper selection of cutting discs. Especially when faced with cutting objects of different materials, choosing the right cutting disc is particularly critical. This article will focus on the cutting characteristics of various common materials and explain in detail how to choose the most suitable cutting blade type according to the material type to help users achieve efficient, safe, and low-cost processing goals in their work.
I. Metal material cutting: pay attention to sharpness and wear resistance
1. Ordinary carbon steel
Recommended cutting discs: metal universal resin cutting discs;
Thickness recommendation: 1.6mm~2.5mm;
Key points of selection: Carbon steel cutting does not require high sharpness, but it needs good wear resistance and high temperature resistance, so choose a cutting disc with moderate price and strong general performance.
2. Stainless steel
Recommended cutting discs: ultra-thin cutting discs for stainless steel;
Thickness recommendation: 1.0mm~1.6mm;
Key points of selection: stainless steel has high hardness and poor thermal conductivity, which is easy to cause heat discoloration or melting of the cut seam, so it is necessary to choose products with high sharpness, good heat dissipation and soft resin binder, which is convenient for the timely renewal of abrasives and reduces the heat-affected zone.
3. Alloy steel / tool steel
Recommended cutting discs: special cutting discs for industrial grade metal;
Thickness recommendation: 1.6mm~2.0mm;
Key points of selection: Alloy steel has higher hardness and is suitable for using cutting discs with uniform particles and high bonding strength to prevent early chipping or burning of the sheet.
II. Non-ferrous metal cutting: anti-blocking and anti-sticking sheets are the key
1. Aluminum, copper, brass
Recommended cutting discs: special cutting discs for non-ferrous metals (with anti-stick layer);
Thickness recommendation: 1.2mm~1.6mm;
Selection points: Aluminum, copper and other materials are prone to the phenomenon of "sticking sheets" in high-speed cutting, and choosing cutting discs specially designed for non-ferrous metals, with smooth chip evacuation and anti-clogging performance, can effectively improve cutting efficiency and finish.
III. Brittle materials such as stone and tiles: high wear resistance, anti-chipping edges
1. Granite, marble, artificial stone
Recommended cutting discs: special diamond cutting discs for stone;
Thickness recommendation: 2.0mm~3.0mm;
Key points of selection: natural stone has high hardness and complex internal texture, so it is recommended to use diamond inlaid cutting discs, which have sharp edges, strong wear resistance, and better anti-chipping ability.
2. Ceramic bricks, vitrified bricks
Recommended cutting discs: ultra-thin ceramic special diamond cutting discs;
Thickness recommendation: 1.0mm~1.2mm;
Key points of selection: Ceramic brittle materials have high requirements for the cleanliness of the cut, and the selection of ultra-thin sheets with thin incisions and uniform cutter heads can greatly reduce chipping and breakage.
3. Plastic, PVC, rubber and other flexible materials
Recommended cutting blades: special cutting blades for flexible materials or medium and low speed cutting saw blades;
Key points of selection: plastic cutting is easy to melt or stick chips, so it is necessary to choose cutting discs with soft abrasives, low heat resistance, low rotation speed cutting effect, and sometimes dry slices of silicon carbide materials.
4. Concrete, cement products, bricks and other building materials
Recommended cutting discs: diamond cutting discs for building materials;
Thickness recommendation: 2.5mm~3.5mm;
Key points of selection: cement, bricks and other materials contain a large number of quartz particles, strong wear, cutting discs need to have excellent wear resistance and impact resistance, it is recommended to use dry and wet cutting discs to improve efficiency.
5. General suggestions: 5 dimensions to consider when selecting
Hardness of cutting material: the harder the material, the higher the requirements for the abrasive of the cutting disc;
The performance requirements of different materials for cutting discs vary greatly, and blind selection will not only cause material loss, tool waste, but may even cause safety accidents. Therefore, whether it is individual users or enterprises purchasing in bulk, scientifically evaluating cutting needs and selecting the appropriate cutting disc model is the key to improving processing efficiency, reducing comprehensive costs, and ensuring operational safety. Mastering the above selection principles will make your cutting operation twice as effective with half the effort.
