Woodworking TCT Saw Blade In The Selection Of The Number Of Teeth On What?

Danyang Youjie Tools Co.,Ltd | Updated: Aug 05, 2016

40 tooth and 60 tooth gear as What is the difference?

40 teeth due to the small friction, will and effort, the sound will be small, but cut 60 tooth smoother. General woodworking with 40 teeth. To the sound of small, use a little thick, thin, but better quality. The more the number of teeth, sawing sectional smoother, if your machine is good and stable performance of the sound will be smaller.


30 tooth  with 40 tooth  is the difference?

Mainly because these:Different cutting speeds. Different gloss. The blade angle of the teeth themselves are also different. The blade body hardness, flatness, end jumping and other requirements are also different. In addition to the machine speed, feed rate and timber, there are some requirements. Blade equipment to do precision have a great relationship. 'Cut back' to the present this is the most difficult.


Why TCT saw blade need cutting lip?

Preventing clip blade;

Increase friction.


More tooth and less tooth saw blade to cut wood What is the difference?

Serrated teeth, the more the number of teeth in general, the more the cutting edge per unit time, the better cutting performance, but more than the number of teeth required more carbide cutting amount, the high price of the blade, but too dense serrated gullets of the chip becomes smaller, easy to cause the blade fever; additionally serrated too, when the feed rate mismatch, then cut per tooth is small, will exacerbate friction with the workpiece edge, affecting the life of the blade . Typically tooth spacing 15-25mm, should be selected according to a reasonable number of teeth cutting material.

To sum up: a small section inferior teeth tooth more smooth section, less than the price of gear teeth of much cheaper, less teeth than the teeth much less likely to burn the blade, if it is multi-saw teeth must use less, If the plywood and the like, must be used to reduce the number of tooth chipping.

Selection and Design for different sheet metal materials processing Woodworking carbide saw tooth type angle


TCT saw blade tooth selecting and cutting angles for different materials.

Of course, any alloy circular saw blades can cut different materials, but the effect is necessarily fatal or life quality results. Alloy circular saw blades are generally ordinary tooth, and multi blade serrated tooth and humpback. Common tooth for a fine-toothed or precision machining, aluminum and the like. Multi-saw for sparse teeth, slotted or open materials and cutting feed rate fast enough product. Suitable cutting teeth or humpback hard metal cutting, and having a depth cutting function. According to design any kind of tooth pitch, diameter and length of the cutting force to consider the design of alloy and thickness. Cooling groove width and length, angle is also very important, undercuts and pitch arc also directly related to the angle of the back teeth must consider the impact of cutting and chip removal. Of course, the substrate thickness is based on blade width by 1 or 0.8 coefficient value is appropriate, so that the matrix Adapters have strong enough impact.


Cutting tool angle depends on the material, but it is basically common side angle, lateral angle typically between 2.5 ° -3 °, the wheel of old and new wheel play small changes, but the best side rake angle in 0.75 °, the maximum allowed greater than 1 °, side angle grinding entirely selected according to the thickness of an alloy wheel diameter reasonably good enough to grind angle. Of course, selecting the outer diameter of the wheel, must pay attention to the wheel center and the edge line formed alloy straight, otherwise the angle can not wear out, here adjustment associated with operator experience or equipment scale. The left and right sides of the grinding process to the product quality of the key ring. Such as moderate or wheel running track error, the next step can not be a good grinding mill after the tool angle or rake angle, because the day after tomorrow can not compensate for deficiencies.


General access angle 15 °, depending on the cutting object can also be increased to 18 °, after the general angle should not be too large, otherwise the increase caused by the grinding force grinding wheel fillet not accuracy. Of course, after a sharp angle increases tool, but poor wear resistance, good abrasion resistance and vice versa, depending on your posterior horn pure requirements given angle, a slight change will not affect the quality of the tool. But back rake inappropriate too large, too large a tool does not wear, easy to broken teeth, grinding wheel is easy to produce rounded corners, prone to arc back rake, Kin Yee access to 11 ° -13 ° is appropriate, but about two must be familiar with the blade when the center side grinding, otherwise form the left and right high or low, directly affecting life.


The cutting rake angle of the workpiece and the cutting speed related. The larger the rake angle, the faster cutting speed, whereas the more slowly. Angle before cutting metal materials not exceeding 8 °, the thin metal minus 3 °, must have a leading edge angle cutting plastic materials for chip removal. The larger the angle formed front edge side of the main blade, cutting the other side loses its meaning, it is good enough for the blade rake angle 3 °, the maximum should not be 9 °, alloy saw blade rake angle and saw blade grinding rake angle is the key link in the most the main blade and the auxiliary blade is accurate grinding out key factor is the main tool life.


The aspect of cutting and finish cutting tooth design is the key. General requirements for Longitudinal cutting rake angle suitable too large, as much as possible cross-cutting rake design bigger, dry wood is suitable for the former, wet enough material applicable to the latter, the longitudinal edge rake angle can be smaller, lateral edge rake angle should bigger. Saw tooth for a different type of complex application of different cutting tooth, such as single or single left and right suitable mill, unilateral cutting plexiglass production line. About tooth for a variety of wood processing. Right and left or right left right left right and left flat flat finish cutting a suitable timber, moldings, plexiglass. Suitable metal ladder flat profile processing or hardwood processing, speaker jewelry boxes, the electronic saw blade angle, still back rake angle will increase. Flat teeth suitable for playing slots, must pay attention to any flat teeth sharpened with the main secondary edge, sharp teeth, inverted tooth appropriate ladder or wooden drawers class 90 ° demolition side, and electronic circuit boards and other purposes.
