ABSTRACT:
A slide drive apparatus and a slide drive method for a pressing machine capable of enhancing positioning precision at the time of adjustment of die height, and responding to pressing work at high stroke per minute. For this purpose, the drive apparatus includes a slide (4), a servo motor (21) for controlling slide motion, a mechanical power transmission mechanism (3, 5, 6) for converting rotational power of the servo motor for controlling slide motion into reciprocating motion of the slide, and a servo motor (31) for adjusting die height, which performs die height adjustment of the slide by a position control.
