Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention can be embodied in many different forms than those herein described and it will be apparent to those skilled in the art that similar modifications can be made without departing from the spirit and scope of the utility model and, therefore, the utility model is not to be limited to the embodiments set forth herein.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for illustrative purposes only and do not represent the only embodiments.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The embodiment of the utility model relates to a novel superfinishing polishing knife, which comprises a knife body extending in the front-back direction, wherein a ball head structure larger than one half of a sphere is coaxially arranged at the front end of the knife body, a neck is arranged between the front end of the knife body and the ball head structure, and the neck comprises a straight line section close to the ball head structure and a conical section close to the knife body, as shown in fig. 1 to 2. The polishing knife provided by the embodiment is specially used for mirror polishing, the roughness reaches below Ra0.03, the manual polishing process is omitted, and high precision and more ideal glossiness can be obtained. The diameter precision of the cutter is 0-3 mu m, the R precision reaches +/-2 mu m, high-precision cutting can be carried out, and the cutter edge is sharp. Compared with the hard alloy end milling cutter, the cutting tool is more wear-resistant and has longer service life. The cutter can be polished, so that the use cost of a customer is greatly reduced.
In this embodiment, the rear end of the ball head structure has a circular section, and the shape and size of the circular section are the same as the end surface of the straight line segment; specifically, the radius of the circular section is smaller than that of the cutter body.
The ball head structure is provided with a connecting part connected with the straight line section, and the connecting part is connected with the straight line section in an end face welding or V-shaped welding mode.
The ball head structure is made of PCD materials, the front end of the connecting portion is made of PCD materials, and the cutter can have good hardness and abrasion resistance.
In this embodiment, the cutter body is made of cemented carbide.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
