Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a disposable ball milling cutter, and more particularly to a ball milling cutter that can be actively replaced with a wear blade to facilitate the implementation. [Prior Art] [0002] The milling machine is mainly a machine tool that rotates a milling cutter having a plurality of cutting edges and simultaneously moves the workpiece feed to cut the workpiece. For a small or mass production, the milling machine can be economically processed. The main machining projects include plane sharpening, surface milling, groove milling, gear milling, and cam milling, and the type of cutting tool is designed. If there is a milling cutter designed for milling planes, End mills for milling end faces or grooves, side sharpeners for heavy milling and sharp cutters, and ball milling cutters for fine milling. Referring to the fourth and fifth figures, the conventional ball milling cutter (3) is formed by integrally forming a plurality of cutters (3 2 ) arranged in a spherical shape at the end of the cutter body (3 1 ) by the circular shape. Arrange the IMr blade (3 2 ) design to perform the fine milling operation on the surface of the workpiece after machining. Since the ball milling cutter is mainly used for finishing machining, it requires extremely high machining precision. When the ball milling cutter wears, the user will Grinding is required to restore the sharpness of the cutting edge and the appropriate cutting angle to extend the life of the milling cutter. However, the cutting edge of the ball milling cutter is curved and has a certain angle of cutting to restore the cutting state of the grinding. It is difficult for users who are good at grinding and refurbishing. It takes a considerable amount of time to return the ball milling cutter to a machinable state. It often takes a lot of time for users who are not good at grinding and refurbishing. It is still impossible to return the ball milling cutter to the machinable state. Only 100102619 can be discarded. The tool cost is greatly increased. The tool cost is greatly increased. 'There is another'.

The reason is that the inventor has in view of the existing ball-shaped milling cutter, which is difficult to recover after wear, and has been assisted by many years of manufacturing and design experience and knowledge in related fields. The ball milling cutter is updated and developed in order to exert its higher practical efficiency. [0003] 发明 ο [Abstract] The present invention relates to a discard ball milling cutter whose main purpose is to provide a movable displacement Wear the blade to facilitate the implementation of the ball 1 first knife. In order to achieve the above-mentioned implementation, the present inventors have developed a ball-type milling cutter as follows: a tool body and a plurality of blades; wherein: the tool body is convexly disposed on the end surface of the tool body with a circular shape Hold the block, and there is a gap between the clamping blocks. In the clamp h. . 1 : i ' The holding block is provided with a locking hole, and the fastener is locked in the locking hole, and the locking piece is clamped by the clamping block. The outer side is locked into the gap; the cutting edge is a body having a blade portion, and the blade is disposed in the gap formed by the clamping block of the tool body, and the blade edge portion is oriented toward the outer side to make the locking member The locking hole of the clamping block is locked into the gap so that one end of the locking piece is perpendicularly disposed against the end surface of the cutting edge, and the cutting edge is clamped with the clamping block. 100102619 By using the 'blank knife' when the blade is worn, the lock can be released to remove the worn knife and replace the new one without the need to discard the entire ball milling cutter due to blade wear or time-consuming grinding damage.
