Horizontal machining center: refers to the machining center in which the axis of the main shaft is parallel to the table, and is mainly suitable for machining box parts.
A horizontal machining center has a horizontal spindle, usually with a square table for indexing rotary motion. Generally, there are 3 to 5 motion coordinates. The common one is three linear motion coordinates plus one rotary motion coordinate. It can make the workpiece complete the processing of the remaining four surfaces except the mounting surface and the top surface after one clamping. Machining box parts. Generally, it has an indexing worktable or a numerical control conversion worktable, which can process all sides of the workpiece; it can also make joint movements of multiple coordinates to process complex spatial surfaces.
The working principle of horizontal machining center：
After the workpiece is clamped once on the machining center, the digital control system can control the machine tool to automatically select and replace the tool according to different processing procedures, and automatically change the machine tool spindle speed, feed rate, and the movement path of the tool relative to the workpiece and other auxiliary functions. Complete multi-process machining on multiple surfaces of the workpiece. And there are a variety of tool change or tool selection functions, so that the production efficiency is greatly improved.
Compared with the vertical machining center, the horizontal machining center has a complex structure, a large area, and a higher price. Moreover, the horizontal machining center is inconvenient to observe during processing, and it is inconvenient to clamp and measure parts, but it is not convenient for chip removal during processing. Easy, good for processing.
The horizontal machining center is divided into fixed column type and mobile column type according to whether the column moves.
