Brazing/solid disc saw blade series (Super high wear-resistance/high impact-resistant application)
. Saw blade tooth profile
A tooth: straight tooth (ratched type)
It is mainly applied in finish milling and cutting. Its milling and cutting depth is shallow, about 3~5mm.
AW tooth: it is improved one based on A tooth. Tooth profile is left and right single inclined type. Its tooth function is same as that of A tooth, but its efficiency is higher.
B tooth: curved tooth (cam-generated type)
Tooth profile is bending flat tooth, mainly applied to cut deep groove. The cutting resistance is stronger than A tooth and the groove is deeper.
BW tooth: curved tooth (alternately beveled)
Tooth profile is left and right single inclined bending flat tooth, the improved one based on B tooth, mainly applied to cut thicker material of abnormal profile, with stronger cutting resistance, applied for general cross-cutting saw.
C tooth: HI-LO tooth (three-tooth regrinding; rough and finish tooth machining)
Its tooth profile is high and low ladder tooth profile. The difference between front and back tooth is 0.150.3mm. The front tooth is double-bevel, and the back tooth is flat. Its cutting efficiency is high, and can reduce cutting force when assisting in cutting saw.
BR tooth: it is latest improved design of B tooth, with a fine cutting groove of about 0.4mm at the top of tooth. Its function is to re-break waste materials from cutting and sawing work pieces and to increase discharge rate, so that comparing with BW tooth, its cutting and sawing efficiency increases by 25%.
