摘要： PURPOSE:To improve the productivity of various workpieces by allowing a facing space between a pair of side cutters to be changed into the facing space corresponding to the workpiece without changing the side cutters even in the case of changing the workpiece to the one different in the width of the machined part in a machining device for simultaneously cutting the top and rear faces (both sides) of the workpiece end part parallel with the required width by a pair of side cutters. CONSTITUTION:The tip of a spindle 2 rotatably journalled to fixed members 1 is fixedly provided with a fixed side cutter 6. The tip of a sliding shaft 7 axially piercing the inside of the spindle 2 so as to be rotated integrally with the spindle 2 while being relatively movable in the axial direction is fixedly provided with a movable side cutter 9 facing the fixed side cutter 6 in front of the fixed side cutter 6. The sliding shaft 7 is moved forward/backward by a wedge 10 wedged between the fixed members 1 and the sliding shaft 7 to adjust a facing space between the fixed side cutter 6 and the movable side cutter 9.

摘要： PROBLEM TO BE SOLVED: To provide an identification method for axial force of a bolt which enables identification of the axial force of a screwed bolt without use of data in other processes.
SOLUTION: An ultrasonic wave transmitting and receiving part 34 and a calculation part 42 for propagation time transmit ultrasonic pulse from a head 12a of the screwed bolt 1 toward the axial direction by an ultrasonic probe 22 and receives the reflected pulse reflected by a tip 12b of the bolt 1. Then, the ultrasonic wave transmitting and receiving part 34 measures a first to-and-fro time required to transmit the pulse and receive it, and provide it to a control part 40. Subsequently, a bolt 12 is untightened to a completely untightened state, and the ultrasonic probe 22 transmits ultrasonic pulse from the completely untightened head 12a of the bolt 12 toward the axial direction and receives the reflected pulse reflected by the tip 12b of the bolt 1. Then, a second to-and-fro time required to transmit the pulse and receive it is calculated and provided to the control part 40. A calculation part 44 for the axial force calculates the axial force of the tightened bolt 1 based on the first and second to-and-fro hours and speed of the ultrasonic wave.

摘要： PURPOSE:To assured dynamic balance in the taper machining device by moving a tool holder to the direction inclined to the rotating axial line of a spindle. CONSTITUTION:A tool holder 30 is fitted in a head main body 14 in such a way that the holder can be moved to the direction inclined to the rotating axial line of a spindle 10, so that the holder is moved with a moving member 74 moved. A balance piece 122 is fitted in a guide cylinder 120 which passes through the cut-out 110 of the tool holder 30 so as to be fixed in the direction perpendicularly intersected with the rotating axial line of the head main body 14, in such a way that a balance piece 122 can be moved, so that a pin 130 is engaged with an engaging groove 114 which is formed in the tool, holder 30 while being still more inclined in the inclined direction of the holder in such a way that the pin can be moved. A tapered hole is machined while both the tool holder 30 and a cutting tool 56 are moved to the direction that they approach the rotating axial line O as the tool holder 30 is advanced, and the balance piece 122 is moved to the radial direction of the spindle 10, that is, the reverse direction of the tool holder 30, so that dynamic balance is thereby assured.

摘要： PROBLEM TO BE SOLVED: To fasten a fastened tool at a high speed with high accuracy by using a rotating fastening device.
SOLUTION: High-speed fastening is performed by driving the rotating fastening device with high driving energy in starting the fastening. The driving energy is inhibited when fastening torque reaches driving energy switching torque Te. Whereby the over-chute of the fastening torque after the fastening torque reaches cut-off torque Tc and the driving energy is cut off, can be reduced, and final torque can be controlled to be close to target fastening torque Tt.

摘要： PROBLEM TO BE SOLVED: To cut off cutting chips by improving surface roughness during vibration cutting. SOLUTION: A low-rigidity part 24 capable of elastic deformation is provided at a midway position in the lengthwise direction of a tool body 22 whose cutter 21 has a cutting edge 5a. The low-rigidity part 24 is constituted of eight of first to eighth beams 26a to 26h separated from each other by seven of first to seventh through-hole parts 25a to 25g. The four beams are extended almost in parallel along the lengthwise direction of a shank 22, and the other four beams are inclined at a slight angle α to compensate for displacements S1, S2 in the lengthwise direction for balancing, and are vibrated almost in parallel in the feed direction.

摘要： PROBLEM TO BE SOLVED: To prevent a sliding shaft from becoming eccentric relative to a main spindle during machining by providing a clamp mechanism for holding the sliding shaft so as to be relatively not movable in the condition that it has been positioned to be coaxial with the main spindle, between the main spindle and the sliding shaft. SOLUTION: When the adjustment between a fixed-side milling cutter 14k and a movable-side milling cutter 16 is completed in accordance with the thickness of a workpiece to be machined, an unclamp shaft 24 in which the action of an unclamp cylinder has been released is pushed downward by the spring force of a spring 24s and is returned to its initial position. Thereby, a collet chuck 20 is operated, and the sliding shaft 16 is locked so as to be relatively unmovable in the condition that it has been positioned to be coaxial with the main spindle 14. Thus, the sliding shaft 16 is prevented from becoming eccentric relative to the main spindle 14 during machining.

摘要： PURPOSE:To restrict wear of the tapered part of a tool and the tapered part of a main spindle by providing a specified clearance between the tapered part of the main spindle and the tapered part of the tool, with the tool fixed to the main spindle. CONSTITUTION:The receiving face 14s formed around the tapered projected part 14s of a cutting tool 14 is in face-contact with the tip face 12d of a main spindle 12 with the cutting tool 14 fixed to the main spindle 12. Further, about 20mum clearance is provided between the tapered recessed part 12t of the main spindle 12 and the tapered projected part 14s of the cutting tool 14. Thus, force caused by bending moments due to machining is not applied to the tapered projected part 14s of the cutting tool 14 and the tapered recessed part 12t of the main spindle 12. As a result, the tapered projected part 14s and the tapered recessed part 12t practically do not wear with time. The positioning accuracy for the cutting tool 14 is not reduced.
