Thus, the detailed description of the embodiments of the present invention provided below is not intended to limit the scope of the utility model as claimed, but is merely representative of selected embodiments of the utility model.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

Example (b):

as shown in fig. 1-8, an insert having a chamfered configuration. The cutting edge grinding tool comprises a blade body, wherein the edge of the blade body is a cutting edge, the cutting edge is formed by grinding the edge of the blade body together by a chamfer A and a chamfer B, and a mounting hole is formed in the center of the blade body. And taking the surface of the chamfer A of the blade body as the A surface of the blade, and taking the surface of the chamfer B of the blade body as the B surface of the blade.

The inclination of the chamfer A is greater than that of the chamfer B, and in fact, the existing blade only uses the chamfer A to form a blade edge, the blade edge is flush with the surface B, the sharpness of the existing blade is high, but the blade edge is easy to wear, the blade edge is easy to break, and the blade edge is easy to jump in the processing process, especially when being used on a handheld lathe tool.

The angle of the chamfer B is 10-25 degrees, the depth of the chamfer is 0.2-0.5 mm, and the influence on the sharpness of the blade is small in the range of the angle and the depth. Meanwhile, the cracking of the acrylic material and the resin material during processing can be relieved, so that the processing method is suitable for processing the acrylic material and the resin material.

The mounting hole is circular, and its inside face on the blade body is the toper face, and in fact, the mounting hole is the hole that current installation standard corresponds, only is used for the location of installation and processing.

The shape of blade body is various, lists two kinds of comparatively classic cutter body shapes below:

(1) circular cutter body

As shown in fig. 1-2, the insert body is circular, the cutting edge is a circumference, the chamfer B is an oblique chamfer surrounding the cutting edge, and the chamfer B is a conical surface as a whole.

(2) Square cutter body

The square cutter body has two chamfering modes, namely chamfering according to the trend of the cutting edge and chamfering integrally by taking the center of the B surface as a standard, and the detailed method comprises the following steps:

as shown in fig. 3-5, chamfering is performed according to the trend of the edge: the blade body is square, and the cutting edge is the four sides, and the cutting edge place limit is the arc, and its chamfer B is for using the whole chamfer of the center of blade body B face as the centre of a circle, and chamfer B is whole for the arcwall face.

As shown in fig. 6 to 8, chamfering is performed with the center of the B-plane as a standard whole: the blade body is square, and the cutting edge is four sides, and the cutting edge place limit is the arc, and its chamfer B is the curved chamfer that corresponds with the cutting edge radian.

When the blade body is a square blade, a shallow recess is arranged on the surface A or the surface B of the blade to be used as an identification point. The marking points are round depressions or other shapes which meet the requirements, such as triangles, squares and the like, and the round shapes are adopted because the round shapes are convenient to process and accurate in positioning. The marking point is arranged to ensure that the blade of the square cutter body plays a role of marking the starting point when being installed.

In fact, the mark point is arranged on the surface A or the surface B and is determined according to the installation position of the blade, the mark point is reasonably arranged on the outward surface of the blade, and after all processing is finished, the mark point is positioned on the edge formed by the chamfer of the surface B.
