Title:
RAM DEFLECTION CORRECTION DEVICE AND CORRECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2011/055597
Kind Code:
A1
Abstract:
Provided are a ram deflection correction device and a correction method which are capable of simultaneously correcting the displacement and the inclination of a ram tip. For this purpose, the ram deflection correction device, which corrects the deflection of a ram (15) of a machine tool supported by a saddle in such a way as to be movable in a horizontal direction (H), comprises a first tension bar (21) which is installed along the horizontal direction (H) and above the centerline (L) of the ram (15) and which provides a tensile force (F1) that pulls the tip of the ram (15) inward, and a second tension bar (22) which is installed along the horizontal direction (H) and above the centerline (L) of the ram (15) and which provides a tensile force (F2) that pulls inward at a position located inward of the tip of the first tension bar (21).
