Description
Carbide saw blade,Carbide blade cutter

Definition of solid carbide metal saws blade (flat teeth series):
Solid carbide saw blades with parallel outside contour lines and inner hole axes are called flat saw blades; those that the lines do not parallel are called deformed teeth saw blades, including single-angle, unsymmetrical double angle.symmetrical double angle, convex and concave milling cutters, key slotting cuters, etc.
Most commonly seen and used are the flat carbide metal saws blade.those that are entirely made of solid carbide metal materials are called profile solid carbide flat teeth metal saws and profile solid carbide deformed teeth metal saws. In absence of special requirement, the profile solid carbide metal saws (flat teeth saws) can be produced with specification of the six major factors of outside diameter x thickness x inner diameter x teeth number x boss diameter (if applicable)-material to be milled.

Solid Carbide Metal Saw Blade Use Direction:
The profile solid tungsten carbide metal saw cutters have many excellent features, however its durability is inferior to high-speed steel metal, so then the cutting engineering is not properly choose or when the machine bed has inferior accuracy, the edge is easily damaged. How to avoid the shortcoming and take advantage of its feature lies its proper use. the thinner a carbide metal saw cutter is, it will be more sensitive to vibration and tensile stress during operation, and it will be liable to be damaged in the presence of a radial run-out .therefore the milling machine has to be in an optimum working condition, namely with a high machine accuracy, highly rigid cutter arbor, smooth drive and adequate cooling, the specific requirements are as follows:
(1)The installation accuracy of the milling cutter onto the cutter arbor usually should be as follows: radial runout 0.02mm;axial runout 0.01mm
(2)Both sides of the cutter blade should be clam ped onto the cutter arbor with as large as possible flanges so long as not to adversely affect the milling depth ,so that the vibration is absorbed and both sides of the saw are prevented from being pressed.in normal cases,the diameter of flanges must not be less than 1/3 of the outer diameter of the saw.
(3)A reasonable milling linear velocity Vc and amount of feed per tooth Sz should be choose. under equal conditions, usually a Vc faster than that of the HSS metal saw blade may be choose for the solid carbide metal saw cutter, however the amount of feed per tooth should be lower than that of the HSS metal saw.
Usually ,its Sz is set from 0.005 to 0.025mm/tooth . the specific parameters are determined by the operator according to the milling machine speed,properties of material to be milled,the outer diameter ,thickness,number of teeth of the milling cutter, cutting depth and other factors.
