Abstract

PURPOSE:To increase guide faces at the time of high-speed reciprocating motion so as to improve load capacity to rotational moment and to heighten the reciprocating sliding motion stability of a slider by providing reciprocation guide mechanism, formed of serrations, between the guide face of the slider and that of a base. CONSTITUTION:On the upper face of a base 1, a serration 18 is formed into length corresponding to the moving distance, and a serration 19 slidably fitted to the serration 18 is formed at the lower face of a slider 4. A placing base 20 is fitted to the upper face of the base 1 by a bolt 21, and an upper guide 23 is fitted to the upper face of the placing base 20 by a bolt 23a through a gap adjusting shim 22. A serration 24 is formed at the lower face of the upper guide 23, and a serration 25 slidably fitted to the serration 24 is formed on the upper face of the slider 4. The serrations 18, 19, 24, 25 are formed of parallel trapezoidal protruding and recessed parts. Accordingly, at the time of machining with the high-speed feed of a bite 7 fitted to the slider 4, the sliding guide of high-speed reciprocating motion is performed by the sliding fitting of each serration to stabilize this reciprocating motion.

[Problem to be Solved by the Invention] In recent years, as a means of increasing the speed and efficiency of turning processing, servo motors have been rotated at high speeds exceeding approximately 3,000 r.p.m. due to structural constraints. Therefore, the lead of the screw shaft j of the ball screw mechanism f is, for example, a screw shaft with an outer diameter of 16 mm and a high lead of 16 mm. This structure allows slider b to reciprocate at high speed,
We are trying to perform high-speed turning.

However, in the case of the conventional reciprocating guide mechanism described above, when the slider b is reciprocated at high speed, a rotational moment in the torsional direction is applied to the slider b in addition to the force in the reciprocating direction. Due to the influence of this rotational moment and the long distance between the cutting tool and the guiding structure, the slider's guiding accuracy is reduced.
This has the disadvantage that high precision machining may not be possible.
