Example Embodiment

[0019] See figure 1 The cutting tool for metal processing of the present invention includes a cylindrical tool holder 1 and at least one blade 2. The blade 2 may preferably be cemented carbide or other high-hardness materials, and the tool holder 1 has at least one blade 2 At least one blade seat 11 of the tool holder 1 is provided with a chip channel 12 at the rear end of each blade seat 11 that facilitates the falling of chips. The chip channel 12 is preferably a spiral shape consistent with the rotation direction of the tool holder. A circular ring 13 with a diameter larger than the diameter of the tool holder 1 is provided at approximately the middle position of the tool holder 1, and a connecting part 14 connected to the transmission shaft is provided at the rear of the tool holder 1, figure 1 An embodiment of the connecting portion 14 is shown in FIG. The connecting portion 14 may be in a cylindrical shape with cutouts on both sides of the cylinder. Rotational movement is t...

Abstract

The invention discloses a cutting tool used for metal processing, which comprises a cylindrical tool rest (1) and at least one blade (2), wherein the tool rest (1) is provided with blade bearings (11) for containing at least one blade (2); the rear end of each blade bearing (11) is provided with a cuttings channel (12) which is favorable for cuttings to fall off by the tool rest (1); each blade bearing (11) is a groove and is provided with three supporting surfaces for abutting against the blade (2), wherein the three supporting surfaces are respectively a cutting supporting surface (15), a longitudinal supporting surface (16) and a radial supporting surface (17); and at least one of the longitudinal supporting surface (16) and the radial supporting surface (17) is provided with at least one circular-arc notch (19). The hardness of the material is improved by the design on the tool rest structure, and therefore the tool has high fatigue strength. Meanwhile, material surface polishing is used to lower the possibility of forming fissures. In addition, the cutting tool has the advantages of simple structure and low cost and is convenient to manufacture.

Description

technical field [0001] The invention relates to the field of metal processing, in particular to a cutting tool for metal processing. Background technique [0002] There are various types of cutting tools used for chip removal in metal materials, which are used for drilling, grinding, turning, planing, milling and other processing tools, and the tools used for drilling, grinding and turning are Basically, they all have one thing in common. These tools usually include one or more blades and a tool holder that accommodates these blades. The rotation of the tool holder shaft drives the tool holder to rotate, so that the cutting edge of the blade forms a circular motion to cut the workpiece. Operation. [0003] As the materials of workpieces become more and more advanced, the characteristics of workpieces are also continuously improved, so that the static and dynamic loads on the tools acting on these workpieces become higher and higher, so it is necessary to effectively improve...
