Send pressure oil to move the piston 21A fully in the C direction. Then, the shifter 11 also moves in the C direction via the rod 21a, and the gear G4 held between the cam followers 12.12, together with the gear G3, fully moves on the shaft 9 in the C direction to the position shown in FIG. gears G4 and 05 mesh with each other. When the motor 6 is driven to rotate in this state, the rotational force of the motor 6 is transmitted to the worm G6 via the gears Gl, G2, G4, and G5, and further to the worm wheel G.
7 and shaft 23, the tool rest 5 is driven to rotate in the directions of arrows A and B in FIG. Since the worm wheel G7 is movable relative to the shaft 23 in the directions of arrows G and H,
Even if the worm G6 moves in the G and H directions, the rotation of the worm G6 can be smoothly transmitted to the shaft 23.

The piston 23a is lowered together with the shaft 23 in the H direction. Then, the coupling plate 5a is fitted into and secured to the index plate 27, the tool rest 5 is positioned at a predetermined position with respect to the frame 2, and a predetermined tool rotation spindle, e.g.
The clutch plate 31A connected to the shaft 9A abuts and engages with the clutch plate 32a of the shaft 32 on the frame 2 side.

Then, gear G4 moves to position N via shifter 11, and gears G4 and G3 enter a neutral state in which they do not mesh with any of the gears. Then Bo) 20e
, 20h, the piston 21D moves fully in the direction C, and the piston 21A moves in the direction D until the piston 21A abuts the lock 21d of the piston 21D via the piston 21B, and the gear G4 moves to position H, and gears G4 and 012 mesh. If the motor 6 is rotated in this state, the rotation of the motor 6 will be from the shaft 9 to the gear G.
4゜G12, shaft 35, bevel gear Gll, GIO1 shaft 32
The phase is matched by the start of rotation of the shaft 320,
Clutch plate 32a engaged by the elasticity of spring 33,
31A to the shaft 30 and further to the hook gear G9. It is transmitted to the main shaft 29A via G8, and the main shaft 29A is rotationally driven together with the tool 3, so that a predetermined machining operation can be performed.
。 軸３２が主軸２９Ｂと噛合している場合も同様である。. The same applies when the shaft 32 is engaged with the main shaft 29B.

回転は増速され、主軸２９Ａ、２９Ｂの回転は高速とな
る。The rotational speed of the main shafts 29A and 29B is determined by the ratio of the number of teeth between gears G4 and G12, but at position H, the number of teeth Z of gear G4
4 is larger than the number of teeth Z+2 of G12, the rotation speed of Chiyo 6 is increased, and the rotation of main shafts 29A and 29B becomes high speed.

モータ６の回転は減速され、主軸２９Ａ。When lowering the rotational speed of the main shafts 29A and 29Ll to a low speed, pressurized oil is supplied to the port 20e with the motor 6 stopped. Then, the piston 21A becomes the piston 211
3, 21 While pushing D in the D direction, move it to its full stroke, move gear G4 to position, and move gear G3 to position.
When the motor 6 is rotated in this state, the rotation of the motor 6 is caused by gear 03. Transmitted to the main shafts 29A and 29B via G13, k Jllt0
Since the number of teeth Z3 of G13 is smaller than the number of teeth Z+3 of G13, the rotation of the motor 6 is decelerated and the rotation of the main shaft 29A is reduced.
２９Ｂの回転は低速となる。。29B rotates at a low speed. .
