A small CNC drilling and milling machine

Technical Field

The utility model relates to the technical field of mechanical processing, in particular to a small-sized numerically controlled drilling and milling machine.

Background Art

Small CNC drilling and milling machines are mainly used for milling of ordinary steel, copper, aluminum and non-metallic materials, and are widely used in the process of mechanical processing. When a workpiece is currently processed using a small CNC drilling and milling machine, it is sometimes necessary to machine a groove perpendicular to the inclined surface of the workpiece on the inclined surface of the workpiece (as shown in Figure 4 of the specification). However, the current small CNC drilling and milling machines are generally three-axis structures and cannot rotate the workpiece. For example, the patent that has been authorized, its patent application number is "CN201120104425.9", a small CNC drilling and milling machine and a patent application number is "CN200920120635.X small CNC drilling and milling machine". Since it cannot rotate the workpiece after clamping the workpiece, it cannot machine a groove perpendicular to the inclined surface on the inclined surface of the workpiece. When machining the groove on the inclined surface of the workpiece, the workpiece must be placed on a large four-axis machining center, so that after the workpiece is clamped, the inclined surface of the workpiece is rotated to a horizontal level and then processed using the machining center, which wastes the time of large-scale machining equipment and has low economic efficiency. Therefore, a small CNC drilling and milling machine that can adjust the angle of the workpiece according to actual needs is needed.
