Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the invention of the present application, the meaning of "a plurality" is two or more unless otherwise specified.

In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art through specific situations.

Referring to fig. 1, a new type of face milling cutter with a double-chamfer design of cutting edge, the milling cutter is a carbide milling cutter. The novel face milling cutter with the cutting edge double-chamfer design of the embodiment comprises a back cutter face 1, a front cutter face 2, a cutting edge 3 and a chamfer 4. When the whole milling cutter is machined, the power source drives the cutter point to rotate around the rotation axis, so that the milling cutter is driven to rotate and feed. Preferably, the shape of the cutting edge 3 is a straight line and conforms to the pre-formed structure required by the processing part of the workpiece, so that the highlight effect can be achieved without multiple processing, and the processing precision and the cutting power are improved. The front cutter face 2 is connected with the rear cutter face 1, the chamfer 4 is formed at the joint of the rear cutter face 1 and the front cutter face 2, the cutting edge 3 is formed at the joint of the rear cutter face 1 and the chamfer 4, the front cutter face 2 and the chamfer 3, a front angle is formed between the chamfer 4 and the machining face, and the front angle is 30 degrees.

In one embodiment, the cutting edge is made in the form of a width of 0.015mm to 0.02 mm. Preferably, the width of the cutting edge is 0.018 mm.

In order to ensure the final precision of the processing, in one embodiment, the milling cutter is ground by a grinding wheel in the grinding process, the grinding wheel comprises a high-gloss grinding wheel, and the cutting edge and the corresponding chamfer 4 are ground by the high-gloss grinding wheel. In this embodiment, a high-gloss grinding wheel combination with the grain size SDC2000 and an oil product with a relatively low viscosity may be used, so as to ensure that the saw teeth of the chamfer surface 4 are as small as possible and the grains are as fine and smooth as possible. Preferably, in one embodiment, the rake face 2 and the flank face 1 are both polished by a high-gloss grinding wheel.

In order to ensure the final precision of the processing, in one embodiment, a controller is used for controlling the grinding wheel in the milling process of the milling cutter, and the controller controls the grinding wheel to rotate in real time in the grinding process of the grinding wheel. The milling cutter can be selected from the tool grinder of MAKINO SEIKI, AGE 30. The main shaft is cooled inside, and the stability of the size of the cutter is greatly enhanced through the column structural design. The online dressing of the grinding wheel comprises the matching of the feeding speed and the rotating speed, and the selection of the granularity of the grinding wheel, thereby facilitating the verification of the machining precision and the machining correction.

In one embodiment, the controller is used for controlling the rotation speed and the feeding of the milling cutter in the milling process of the milling cutter. Preferably, in one embodiment, the milling cutter is ground by a high-speed low-feed method. The grinding process adopts a high-rotating-speed low-feeding mode as far as possible, the grinding wheel must be trimmed on line, the vibration is suppressed to the minimum, the precision target and the target effect can be achieved without multiple processing, and the yield of the milling cutter are improved.
