Metal and wood fabrication works involve high degree of precision operations, in which cutting is primary. Engineers have developed numerous designs of blades to cut the metal in the exact dimension as designed on paper. However, a clean cut is hard to achieve even with the sharpest of the blades. Resistance in cutting can lead to edge defects in the final shape of the part or finished good. Heat generation is another issue during cutting operations. To overcome this, the engineers innovated TCT circular saw blade. In this detailed blog, we are going to learn about this blade and how it reduces burrs after cutting.
What Are TCT Circular Saw Blades
A Tungsten Carbide Tipped (TCT) circular blade is a circular disc of high carbon steel on which Tungsten carbide is brazed. These blades are known for their excellent hardness. Compared to steel, the carbide tips are hard and more wear resistant. The steel blade body provides resistance to corrosion and stability, while the teeth has a long service life.
Why Burrs Are Formed During Metal Cutting
Burr formation is the rough chip or raised edges of the metal that remains attached to the workpiece. These are formed when the cutting tool fails to shear the material cleanly. Rather than separating completely, the metal deforms on the edge. Dull cutting teeth, improper cutting speed, machine vibration are some of the reasons behind it.
How TCT Blades Minimize Burr Formation
TCT circular saw blade is designed to reduce the burr formation of the ferrous and non ferrous metals, as well as wood, laminate and pipe production.
Extremely Hard Teeth
Tungsten carbide is a material that is significantly harder than conventional tool steel. The teeth apply an appropriate shear force to slice the workpiece to produce cleaner cuts.
Precise Tooth Geometry
There are many kinds of tooth profiles based on the material to which they will be applied. For example, a blade with nano PVD coating is suitable for cutting solids and non-ferrous metals.
Stable Blade Body
The steel disc is vibration resistant, hence it is stable during cutting operations. The cuts are straight and dimensionally accurate because of this.
Benefits of Burr-Free Cutting
There are many advantages of burr-free cutting in production lines:
- Time is saved on secondary finishing operations to deburr.
- Edges obtained on cutting are smooth and dimensionally accurate.
- Faster production cycles and reduced labour.
- Better fitting of the parts during assembly especially in tight tolerances.
Conclusion
To achieve burr free cutting of metals, wood, laminates and plastics, the right combination of tool and speed is required. A TCT circular saw blade is widely used in steel tube manufacturing, structural steel fabrication, equipment manufacturing and general engineering works. Its hardness and stable cutting are why it is preferred. We at NSA Engineering Solutions Pvt. Ltd. provide many variants of TCT cutters for ferrous and solid cutting operations. Our high-quality blades have been well-appreciated by the engineers across the industries.
