New description: [New technical field] This creation is about a type of dovetail milling cutter, especially one: a number of knives I, which can only be used for chip-type dovetail milling cutters when the blade is damaged. [Prior Art] ^In general machining, it is common to use a machine tool to drive a tool to rotate at a high speed, and then perform milling operations such as milling, drilling, etc. on various workpieces, in which, depending on the tool used, Grooves of various shapes such as a T-shaped shape, a V-shaped shape, a dovetail shape, and the like are sharply cut out on the workpieces. In the prior art, a dovetail milling cutter for milling a cross-section of a dovetail shape (or a dovetail shape) is manufactured by integrally forming a high-hardness steel such as high-speed steel or tungsten steel, and one end of the sharp knife is spaced apart. The ring is provided with a plurality of cutting portions extending obliquely in a skirt shape, so as to correspondingly mill a red-tailed groove having a bottom width larger than a width at the opening. However, since the above-mentioned prior art dovetail milling cutter is integrally formed, when the cutting edge of one of the cutting portions is damaged, in order to maintain the integrity of the milled tail groove wall surface, even the other blade portions Still intact, usually only the entire group of dovetail milling cutters can be eliminated and replaced, which will result in material waste and financial loss. [New content] In view of the above-mentioned shortcomings of the prior art, the present invention provides a blade type dovetail slot milling cutter, which is designed to solve the problem of damage to the blade edge of one of the prior art dovetail milling cutters. M398986 for the elimination and replacement of milling cutters. The technical means utilized in this creation is to achieve the above-mentioned creative purpose, so that a blade type dovetail milling cutter includes a - knife seat, and its end spacer ring is provided with a plurality of fixing portions. Each of the skirts extends obliquely and is concavely formed on the same side with a sipe; a plurality of blades respectively disposed in the sipe of the holder and detachably fixed to the corresponding holder The department meets.
