Next, the operation will be described. As shown in FIG. 1 and FIG. 2, while the predetermined tool 3 is indexed to the processing position by the turret head 2 to process the work 4, the ultra-high pressure coolant is jetted to the cutting portion 7. At this time, in the drive mechanism 9, the pressure fluid, for example, compressed air is supplied to the first fluid supply passage 33, and the second fluid supply passage 34 is supplied.
Open to atmospheric pressure. Then, the compressed air is supplied to the supply path 3
3 is supplied to the front chamber 30 to press the piston 26 in the arrow E direction, so that the shaft member 10 is biased in the E direction. As a result, the engaged portion 45 engaged with the cam groove 44 moves the cam member 11 in the G direction. As a result, the seal member 53 is strongly pressed against the swivel sliding portion 48 to prevent the coolant from leaking. The seal member 53 is the cam member 11
Since the size is such that it slightly projects from the end face 54, the seal member 53 directly adheres to the swivel sliding portion 48.

The coolant supplied to the coolant supply passage 32 has a gap 16 between the fixed shaft 8 and the shaft member 10.
Flow through the second flow path 12 in the cam member 11, the inside of the seal member 53, the first flow path 5 in the turret head 2 and the third flow path 14 in the tool 3 to discharge the coolant. It is injected at high pressure from the outlet 14a to the cutting portion 7 to break the chips and cool and lubricate the cutting portion 7.

When cutting with the tool 3 is finished and the tool is to be replaced with the next tool, the drive mechanism 9 is operated before the turret head 2 performs the turning indexing. That is, the compressed air is switched from the first fluid supply passage 33 to the second fluid supply passage 34 and supplied to the rear chamber 31. At the same time, the first fluid supply passage 33 is opened to atmospheric pressure. Then, the piston 26 and the shaft member 10 are urged in the arrow F direction. During switching of tools, supply of coolant is stopped in advance to reduce the pressure in the flow path.

As shown in FIG. 3, when the shaft member 10 is biased in the F direction, the cam member 11 moves to the H position via the cam device 46.
Move a predetermined stroke in the direction. As a result, the seal member 53 separates from the turning slide portion 48. Next, the indexing drive mechanism (not shown) built in the tool rest 1 is driven to rotate the turret head 2 to index the next tool to the machining position.

Make them adhere closely. After that, if the coolant is supplied to the coolant supply path 32, the work 4 is machined by the new indexed tool, and the cooling of the cutting portion 7 by the coolant and the lubrication and the breaking of the chips are performed in the same manner as the previous time. It

As described above, according to the present invention, when the coolant is supplied, the seal member 53 is used for sealing, and when the tool is indexed, the cam device 46 is used to positively disengage the seal member 53 from the swivel sliding portion 48. There is. Therefore,
When the coolant is flowing, the turning sliding portion 48 can be reliably sealed by the sealing member 53. Further, since the seal member 53 is not in contact with the swing sliding portion 48 during the swing indexing operation, damage to the seal surface can be prevented.
