Program-controlled machine tool

摘要

A program controlled machine tool, including a bed-like substructure, a machine frame having two vertical and parallel side walls, and a compound slide having a longitudinal slide which can travel in the direction of the Y-coordinate axis on the two side walls of the machine frame. A cross slide is guided in such a way that it can travel in the direction of the X-coordinate axis. A machining unit can travel in the direction of the vertical Z-coordinate axis and has a working spindle. A workpiece table arrangement arranged on the substructure in front of the side walls. The workpiece table arrangement is arranged on the front partial area of the flat base and the cross slide has a length in the direction of the Y-coordinate axis which corresponds approximately to the diameter of the workpiece table and/or the working space in the Y-direction.

主权项

1. A program controlled machine tool comprising:
a bed-like substructure; a machine frame on the bed-like structure, the machine frame having two vertical and spaced parallel side walls, one being a first side wall and the other being a second side wall that is shorter to the front than the first side wall, both side walls having front ends; a compound slide having a longitudinal slide movable in the direction of the Y-coordinate axis on the side walls of the machine frame, the compound slide also having a cross slide which is movable in the direction of the X-coordinate axis on the front side of the longitudinal slide; a machining unit movable in the direction of the vertical Z-coordinate axis on the cross slide by means of a vertical slide and has an integrated working spindle; a workpiece table arrangement, which is arranged on the substructure in front of the front ends of the side walls of the machine frame thereby defining a working area, wherein: the substructure is in the form of a flat base having cylindrical side and front walls and is rigidly attached to the machine frame; the workpiece table arrangement contains a swivel rotary table having two bearing blocks, the bearing blocks being fixed to the flat base of the bed-like substructure in front of the front ends of the side walls of the machine frame, a first of the two bearing blocks is adjacent to the shorter side wall of the machine frame and the cylindrical side wall of the base only has a bearing for one swivel pin of the swivel rotary table, and drive means for the swivel movements of the workpiece table about the common axis of the two bearing blocks being arranged at the opposite bearing block in addition to the bearing for another swivel pin; the workpiece table arrangement is arranged on a front partial area of the flat base; the cross slide having a length extending from the longitudinal side in the direction of the Y-coordinate axis which corresponds approximately to the diameter of the workpiece table or of the working area in the direction of the Y-coordinate axis; and the cross-slide having a trapezoidal shape in both side view and top view, and the vertical slide of the machining unit being guided on guides at a front narrow side of the cross slide.
