摘要： PROBLEM TO BE SOLVED: To easily position the cutting surface of an insert along a tool holder center line by providing a peripheral positioning member for finely adjusting the peripheral position of the insert. SOLUTION: A flat tip screwdriver, for example, is used to turn a peripheral positioning member 6 via a screwdriver groove formed on the flange 6a thereof, and the axial position of the flange 6a is finely adjusted arbitrarily. As a result, the position of an insert 3 is finely adjusted along a peripheral direction, and the cutting surface 3b of the insert 3 is easily positioned along the center line of a tool holder 1. Furthermore, the cutting surfaces 3b to 3b of each of inserts 3 to 3 in this case are all positioned on the center line at a whirling machining process, and a cutting operation is thereby facilitated.

摘要： PROBLEM TO BE SOLVED: To enable a groove having a specified depth to be cut, even if a workpiece has a non circular shape, in a cutting device for cutting a groove at an outer circumferential surface of the fixed circular workpiece. SOLUTION: A slide 14 is fixed to a surface plate installed at a main shaft in such as way that it may be moved in a diametrical direction. A blade stock is arranged at the slide 14 in such a way that it may be rotated through a supporting shaft 22 and at the same time the tool slide is held at an initial position by a compressive coil spring 34. Then, the tool slide is provided with a roller 28 for restricting a cutting depth of a cutting tool 26 while being abutted against an outer circumferential surface of a workpiece W. When a cutting operation is carried out, the roller 28 is filed along the outer circumnferential surface of the workpiece, thereby, the cutting depth against the outer circumferential surface of the workpiece W with the cutting tool 26 is kept constant.

摘要： PURPOSE:To aim at simultaneously working a vibration preventing device attaching part, by providing such an arrangement that a workpiece is supported by three way rollers of up, down and side, the rollers are coupled to one end of links rotated about a swingable shaft and having the other end attached with cam followers for rotary cams, so that the rollers may follow variations in the diameter of the workpiece. CONSTITUTION:In a link 5 which swings about a stud 15 as a rotational center with supporting rollers 1, 3 being closely contacted to the outer peripheral surface of a workpiece 4, a cam follower 7 is closely contacted to a cam 8 under the pressure force of a torsion spring 13 so that the supporting rollers 1, 3 are allowed to take a sufficient swinging range for supporting the workpiece due to the rotation of the cam 8. Further, a link 6 slides in a guide groove formed in a casing 14, radially of the workpiece 4 under the condition that a supporting roller 2 is closely contacted to the outer peripheral surface of the workpiece 4, and therefore, a cam follower 9 is closely contacted to a cam 10 under the tension force of a tension spring 16 so that a sufficient linear movement for allowing the supporting roller 2 to support the workpiece 4 is obtained due to the rotation of the cam 10. Accordingly, the diameter range of allowable gripping is enlarged and therefore, the working under such a condition that a vibration preventing part is attached, is made possible.
