The number of teeth determines the cutting speed and purity of the material.
The more teeth a disc cutter has, the more fine the ends of the saw are obtained.
The number of teeth determines the cutting speed and purity of the material.
The more teeth a disc cutter has, the more fine the ends of the saw are obtained.
But at the same time, the mechanical load on the engine increases significantly and the process of removing chips from the cutting zone becomes very difficult.
This, in turn, reduces the angular rotation frequency of the cutting mill and the amount of its supply to the material body. And with a small number of teeth, the width of the interdental sinuses increases, which contributes to the effective removal of chips and has a positive effect on accelerating the sawing process.
But at the same time, the end faces of the saw turn out to be of poor quality with a rough, rough surface, requiring additional processing.
Disc cutters with a large diameter and a negative sharpening angle usually have a significant number of teeth.
A small number of teeth, first of all, are endowed with discs of small diameter, which have a positive angle of sharpening the teeth.
For wood processing, for example, the number of teeth is considered large if their number is in the range between 80 and 90 teeth.
A small number usually includes a set of teeth on a milling cutter from 10 to 40 pieces.
Similar ratios are maintained for other materials, including
tsch.
and for metals.
The gap between 40 and 80 teeth occupies the middle position.
Disc cutters with so many cutting elements are designed for various types of processing.
Disk cutters with an average number of teeth work equally effectively with both hard and soft materials, perform both longitudinal and transverse sawing, etc.
D. But at the same time, we must not forget that the number of teeth is also a function of the outer diameter of this tool, which is directly related to other technical parameters of the disc cutter.
