れる。First, let me explain the case of polishing a tool with a spiral cutting edge.60 First, tool A? It is fixed to the tool gripping part 6 of the tool gripping machine 2,
Fully operate the nondle 24 of the first movement adjustment mechanism 19 to move the tool support device 1 in the axial direction, and move the tip of the tool A to the rotating plate 1.
2 and is brought into contact with a centering portion 74 erected on the top of the centering portion 74 . Once the tool Ak is positioned at a position where its tip touches the centering part 74,
After tilting down the centering part 74 and then operating the handle 49 of the vertical movement adjustment part 46 of the grinder support device 42 to position the grindstone 40 of the grinder 69 at the height of the tool A, the second
Operate the handle 65 of the movement adjustment mechanism 20 to move the tool At-
Grind it against the whetstone 40. Next, the total length of the cutting edge of tool A is 9
, microswitch 16.1 of tool feed i' adjustment mechanism 5
Contract 1) for 7 days. Next, when the power switch (not shown) is fully turned on and the start button (not shown) is pressed, the motor 10 of the tool rotation drive mechanism 6 rotates, and the cutting edge of tool A rotates to the polishing position. to the optical sensor 68! ll sensing-1;b, and upon receiving this sensing signal, motor 1
The rotation of u stops, and then the motor 11 of the tool rotation drive mechanism 6, the motor 15 of the tool feed drive mechanism 4, and the motor 41 of the grinder 69 start rotating. The motor 11 is a tool A
'lk This is a lead motor that rotates motor 15.
As the tool A moves forward due to the drive of the optical sensor 6
8 senses the entire cutting edge of tool A and rotates the motor 11 according to the lead of tool A. Here, the tool A is reliably polished by the grindstone 40 of the grinder 69.

研磨の一工程が終了する。When the blade length of the tool A has been polished, the female threaded portion 14 provided on the rotary shaft support 8 comes into contact with the tool feed 9 amount adjustment mechanism 50 microswitch 16, and upon receiving this contact signal, the motor 11, 15. 41 comes to a seat stop, and at the same time, the solenoid 67 of the movement forcing section 66 provided in the second movement adjustment mechanism 20 is energized, and the tool support device 1 is moved in a direction perpendicular to the axial direction and away from the grindstone 40 of the grinder 69. Then, in this state, the motor 15 reverses, and the rotary shaft support part 8, that is, the tool A, retreats, and the rotary shaft support part 8 & 2: the provided female threaded part 1
4 comes into contact with the microswitch 17, the motor 15 is stopped, and at the same time, the excitation of the solenoid 67Q) is also turned off. In this way, one process of polishing a tool having a spiral cutting edge is completed.

い。Next, the case of grinding a tool with a straight cutting edge is similar to the case of grinding a tool with a spiral cutting edge, and since the cutting edge is straight in this case, the tool is moved by the motor 10 only when positioning the first blade. The motor 11 does not need to be rotated after that, and the motor 11 is not driven.

。Next, operate the handle 49 of the vertical movement adjustment unit 46 of the grinder support device &42 to position the grindstone 40 of the grinder 69 at the height of the tool A, and then fully operate the handle 56 of the approach/separation IJIJ adjustment unit 44 to remove the grinder. All of the grindstones 40 of No. 69 are brought into contact with the outer periphery of the tip of the tool A from the direction of the axis Kid: of the tool A. Next tic Turn on the power switch r (not shown) of the circuit configured for grinding the tool A (ball end mill) and then press the start button (not shown), the motor 41 of the grinder 69 will rotate and the tool A(
7) At the beginning of the entire polishing process, the motor 65 of the rotary drive device 57 is activated at the same time.
rotates and rotates the rotating shaft 61 through all the gears 65.6jl. For the rotation of this rotating shaft 61, the worm 58 has 91
Since the end 66 of the gear 62 is in contact with the bracket 60, the rotation of the gear 62 causes the entire arm 47, which rests on the grinder support 48, to rotate around the shaft 46, and the end 66 of the gear 62 is in contact with the bracket 60. Once rotated, the motor 65 contacts the microswitch, stops the microswitch 41, and rotates the motor 65 in the opposite direction. The tip of the c9 tool A is rotated by the rotation of the arm 47, that is, the rotation of the grinder support device 420, and by the downwardly formed tapered surface of the rotary plate 72, which rotates with the rotation of the arm 47. The tool A is tilted upward and downward in the axial direction, and the 4IIEM by the grinder 69 is performed according to the lead of the cutting edge at the tip of the tool.

る。When the motor 65 rotates in the reverse direction, the rotating shaft 61 first moves straight in the axial direction until the end 67 of the gear 62 comes into contact with the bracket 59 due to the reverse rotation of the gear 62. This rotating shaft 61 goes straight IN! The lever 69 of the IIC machine 9 approaching/separating movement force unit 68 is rotated to pull the male threaded rod 51 in the separating direction against the spring 54, and as a result, the grinder support 4
8 is forcibly separated in the direction of separation, and the grinder 6
The grindstone 40 of No. 9 is separated from the tip of the tool A. motor 65
The end portion 67 of the F gear 62 becomes a bracket during the rotation of
When it comes into contact with Vc, further straight movement is blocked, arm 47
That is, the grinder support device 42 rotates backwards to its original position, that is, rotates 90 degrees backwards, and comes into contact with a microswitch (not shown) at the 1ζ point, which causes the motor 65 to rotate forward again, causing the end 66 of the gear 62 to move @ After advancing and rotating until it comes into contact with the bracket 60, it stops. In this manner, one process of polishing the tool A, that is, the ball end mill, is completed.
