How You Can Pick Suited TCT Saw Blade

DSC_1319.jpg    TCT saw blades combine many parameters, such as tooth shape, angle, number of teeth, circular saw blade, blade diameter, TCT variety, etc., to establish the processing potential and cutting function of the saw blade. Learn that you can better choose the right blade parameters as needed.

Commonly used tooth shapes have uniform teeth, sinus teeth, trapezoidal teeth, etc., and even teeth are widely used. Typically used in typical wood saws, this serration is simple and robust in the serration, making the bottom lever smoother in the slot approach operation. Even though the sinus saw blade is good at cutting serrations, it is ideal for cutting all types of wood-based panels and overlays. For a trapezoidal tooth saw blade, it is sufficient for cutting the cover layer and the fireproof board, which allows a relatively high saw cut quality.


    The angle of the sawtooth, the cutting position of the sawtooth, can reflect the overall performance of the cutting effect, the largest of which is the rake angle γ, the back angle α and the wedge angle β. As the sawing angle of the serration, the rake angle is usually between 10-15°, although the larger the rake angle, the faster the cutting.


    As the intersection angle in the sawtooth and the machined material, the relief angle is intended to prevent friction between them. The larger the back angle, the smaller the friction and the brighter the processing. Usually the back angle of the TCT saw blade is 15°.


    In the rake angle and the back angle, the wedge angle should not be too small to maintain the sawtooth strength, radiation ability and durability. The sum of the above three angles should be 90°.


    In general, the greater the number of teeth, the larger the cutting blade per unit time. More importantly, the more sawtooth, the better the overall performance of the cutting. However, it requires a wider variety of TCTs, which means that diamond saw blades are more expensive. Too close to the serrations will reduce the ability of the teeth, increasing the friction between the workpieces and affecting the life of the blades. Usually the insertion pitch is between 15 and 25 mm, and a reasonable number of teeth is selected depending on the sawn timber.


    In theory, the thinner the saw blade, the better. In fact, kerf is a kind of consumption. The thickness of the saw blade is determined by the material of the TCT saw blade and the sawing process, taking into account the stability of the saw and cutting material.


    Depending on the cutting equipment used and the thickness of the cutting workpiece, the diameter of the saw is small, which may result in a relatively low cutting speed. If it is really large, the cutting performance will be improved, but the requirements for sawing equipment are higher.


    The choice of tooth shape, angle, tooth type, thickness, diameter and TCT constitutes the entire TCT saw blade, and if selected and moderately matched, it can be fully utilized.
