CNC blade is the general name of indexable turning blade, and is the mainstream product in the field of modern metal cutting application. Mainly used in metal turning, milling, cutting grooves, thread turning and other fields. Next, to understand the NC blade model identification, NC blade model description.

Identification of NC Blade Type

CNC blades usually have a series of letters and numbers as the model of CNC blades. For professional personnel, it is very simple to understand the meaning of these letters and numbers, but for many businesses, these letters are recognized, the meaning of letters is completely unknown. NC blade direct pin, the following small knitting will introduce the model of NC blade for you.

Firstly, a simple example is given to outline the type of NC blade to be introduced. DNMG150408-MS is a blade, the general blade model is represented by 10 numbers. The first four letters in this model represent the characteristics of the blade, and the next six numbers represent the size and type characteristics of the blade.

D denotes 55 degree diamond blade, N denotes 0 degree rear angle of blade, M denotes accuracy grade of blade manufacture, G denotes front edge surface and center hole, 15 denotes length of cutting edge, 04 denotes thickness of blade 4.76mm, 08 denotes arc radius of tool tip 0.8mm.

(1) The first letter generally denotes the shape of NC blades. Commonly used are H, O, P, S, T, C, D and E, which are hexagonal, octagonal, pentagonal, square, 80-degree diamond, 55-degree diamond and 75-degree diamond.

(2) The second letter clearly indicates the angle of the blade's rear angle. The commonly used letters are A, B, C, D, E, F, G and O. A means the angle of the blade's rear angle is 3 degrees, B is 5 degrees, C is 7 degrees, D is 15 degrees, E is 20 degrees, F is 25 degrees, G is 30 degrees, N is 0 degrees, P is 11 degrees, and O means the other angle of the blade's rear angle.

(3) The third letter denotes the accuracy level of the blade. The most commonly used ones are M-level and G-level. Generally, rough and semi-finish blades are M-level, while precision and super-hard blades are G-level.

(4) The fourth letter represents the razor blade's front edge and central hole (groove and hole).

(5) There are six figures, which are divided into three groups. The first group represents the blade length, the second group represents the blade thickness, and the third group represents the blade tip arc radius.

(6) - The letters behind indicate the material of the blade. There are many materials of the NC blade. The products produced by different materials will be different naturally. Therefore, when purchasing the NC blade, we must pay attention to selecting the material of the blade. The price of different materials is also quite different. Generally, it is expressed by two letters, most of which are alloys, P for steel, M for stainless steel, K for gray cast iron or ductile iron, N for aluminium/scrap iron, S for heat-resistant alloy or titanium alloy, H for high hardness material, etc.
