0, hereinafter this operation is called black line alignment). Thereafter, the operation switch 43 is pressed to automatically process the wood 31 based on the position of the turret head 24 in the X direction.

[0004]

The speed of the manual movement is 6 to 8 m so that the turret head 24 can be finely adjusted by moving the turret head 24 right and left to make the black line alignment work easy.
m / sec. In addition, it is sufficient if the speed at the time of processing with the cutters 20 to 22 is approximately the same,
The same speed was used. Therefore, even when the plate thickness detecting section 23 of the turret head 24 is brought closer to the upper surface of the wood 31, the same moving speed is necessarily used.

However, when the turret head 24 is near the upper limit of the elevating range (for example, 450 to 480 mm) and the timber 31 is as low as about 90 mm in height, about 320 to 3
It took about 1 minute to move at a speed of 6 to 8 mm / sec over a distance of 90 mm, and the operability was poor. In the case where the turret head 24 is manually moved in the left-right direction to align the front mark 33 with the black line 32, it is difficult to align the black line if the moving speed is high. Also, manually operate cutters 20-22.
Turret head 24 up and down, left and right,
When processing wood by moving back and forth, if the moving speed is high, the processed surface becomes rough, and chipping and burrs are likely to occur. For this reason, a speed of about 6 to 8 mm / sec has been used as an appropriate place.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art, shorten the black line alignment time, improve operability, and improve manual operability and work efficiency.
