摘要： PURPOSE:To permit the simultaneous machining of two holes without any interference between baldes by rotating two holders whose blades are installed in their radius positions of holes with a fixed phase difference and at the same angular speed, in a device for machining interference parallel holes having a distance between the centers of two holes less than the sum of radiuses of holes. CONSTITUTION:Chips 88, 90 cutting interference parallel holes 12, 14 of a housing body 10 are installed on an end of body sections 96, 98 and an adjustment is made so that their rotating radiuses can be equal to radiuses of holes 12, 14. And axial centers of rotating axes 32, 34 are placed in centers of holes 12, 14. Furthermore, to rotating axes 32, 34, body sections 96, 98 formed in rectangles are equipped with the phase difference of 90 deg. and meshing is made by preparing gears having the same number of teeth. This constitution permits that since rotating axes 32, 33 rotate at the same angular speed, chips 88, 90 always keep the phase difference of 90 deg. and no mutual collision occurs and thus the simultaneous machining of holes 12, 14 can be performed.

摘要： PROBLEM TO BE SOLVED: To obtain a tool holder mounting/demounting jig, for automatically mounting/demounting a holder body to a main spindle. SOLUTION: Fitting a drill holder 12 to a position where the engaging recess 108 of a groove-attached collar 90 is engaged with an engaging pin 354, into the housing hole 402 of a tool holder mounting/demounting jig 10, retains the drill holder 12 incapably both in relative movement and relative rotation in an axial direction. Fitting the sleeve 20 of a main spindle 14 into the drill holder 12 in this condition, fits the drill holder 12 to the sleeve 20 by the rotation of a rotation collar 150 into a fixed phase. In demounting the drill holder 12, it, retained on the sleeve 2, is fitted, to a position where the V-groove 100 of the collar 90 is engaged with an engaging pin 354, into the housing hole 402 of the jig 10, and then the drill holder 12 can become into a relatively rotatably retained condition on the jig 10. Rotating the sleeve 20 by a fixed angle in this condition, rotates the collar 150 into a release phase, thereby demounting the drill holder 12 from the sleeve 20.

摘要： PROBLEM TO BE SOLVED: To provide a reamer for finishing a circular hole with a high roundness and a good surface roughness. SOLUTION: A main groove 20 extending in the axial direction is formed on the outer peripheral surface of the body 12 of a reamer 10. A coolant blast-off port 26 is formed to one side groove side surface 22, and a chip 32 is fixed to the tip angle part of the other side side surface 28, and an edge part 70 furnished with the first and the second main cutting edges, an auxiliary cutting edge 42, a rake face 34, and the first auxiliary flank 40, is formed. An auxiliary groove 59 is fomred neighboring to the main groove 20. The side surface of the auxiliary groove 50 near the main groove 20 is made as the second flank 52, and the groove side surface 60 at the opposite side is formed square to the outer peripheral surface of the body 12. The outer peripheral surface of the part of the body 12 where the grooves 20 and 50 are not formed is made as a guide surface 74. The radius of the guide surface 74 is smaller by 3.5 μm to 5.5 μm than the turning radius of the auxiliary cutting edge 42. The guide surface 74 carries out the guide, and the edge part 70 carries out the finish process of the inner peripheral surface of a circular hole. The groove side surface 60 of the auxiliary groove 50 prevents the insertion of chips between the guide surface 74 and the inner peripheral surface of the circular hole.

摘要： PROBLEM TO BE SOLVED: To provide a valve seat machining device and a method high in machining accuracy and excellent in durability. SOLUTION: A head 68 holding a main cutting tool 120 and first and second auxiliary cutting tools 134, 138 is rotatably fitted to an eccentric fit-in protruding part 56 eccentric from the axis of a main spindle 10, and rotated by a head driving shaft 146. The main cutting tool 120 and the first and second auxiliary cutting tools 134, 138 are therefore changed in distance from the axis of the main spindle 10, and at the time of machining large and small tapered faces 132, 136, the first and second auxiliary cutting tools 134, 138 come in contact with a valve seat 110, but the main cutting tool 120 does not come in contact with the valve seat 110. This is reversed at the time of machining a seat face 118. The main spindle 10 advances while rotating, and the head driving shaft 146 is rotated in the same direction as the rotating direction of the main spindle 10 while being rotated along with the main spindle 10. The main cutting tool 120 moves toward the axis of the main spindle 10 on a plane right-angled to the axis of the main spindle 10 so as to machine the tapered seat face 118.

摘要： PROBLEM TO BE SOLVED: To provide a feed per revolution control method for a rotary tool, which can try to reduce maintenance in number, and lengthen the life of the tool. SOLUTION: The feed per revolution of a grinding wheel 1 in a process for grinding a work, is repeatedly changed in such a way not to be synchronized with the pitch P of scratches 15 having been made over the surfaces of each diamond and each grain 11. The scratches 15 are thereby made uniformly while being dispersed over the surfaces of each diamond and each grain 15. Streaks to be transcribed over the surface of the work, are thereby fine, and will never be conspicuous.
