Working Principle Of Horizontal Machining Center

Horizontal machining center refers to a machining center where the axis of the spindle is parallel to the worktable, and is mainly suitable for processing box parts. His working principle is that after the workpiece is clamped once on the machining center, the computer can automatically select different tools, automatically change the spindle speed of the machine tool, and sequentially complete the multi-process processing on multiple surfaces of the workpiece. His advantage is that it can greatly improve production efficiency.

The main axis of the horizontal machining center is in a horizontal state, usually with a square table that can perform indexing rotary motion. Generally, it has 3 to 5 motion coordinates. The common is three linear motion coordinates plus one rotary motion coordinate. It can make the workpiece complete the processing of the other four surfaces except the mounting surface and the top surface after one clamping, which is most suitable. Processing box parts. Generally, it has an indexing table or a numerical control conversion table, which can process all sides of the workpiece; it can also make joint movements of multiple coordinates to process complex spatial curved surfaces. Some horizontal machining centers are equipped with automatic exchange worktables. While processing the workpieces on the worktable at the working position, they can also load and unload the workpieces on the worktable at the loading and unloading position, which greatly shortens the auxiliary time and improves Processing efficiency.

The working principle of the machining center After the workpiece is clamped once in the machining center, the digital control system can control the machine tool to automatically select and replace the tool according to different processing procedures, automatically change the machine tool spindle speed, feed speed, and the tool's movement path relative to the workpiece. Other auxiliary functions, the horizontal machining center (2 sheets) with exchange worktable can complete the 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 of horizontal machining center characteristics is greatly improved. Due to the concentration of processes and automatic tool change, the machining center reduces the time of workpiece clamping, measurement and machine tool adjustment, etc., so that the cutting time of the machine tool reaches about 80% of the start-up time of the machine tool (common machine tools are only 15-20%); It also reduces the time of workpiece turnover, handling and storage between processes, shortens the production cycle, and has obvious economic effects. The machining center is suitable for small and medium batch production with complex parts, high precision requirements, and frequent product replacement. Compared with the vertical machining center, the horizontal machining center has a complicated structure, a large area, and a relatively high price. Moreover, the horizontal machining center is inconvenient to observe during processing, and it is inconvenient to clamp and measure parts, but the chip is discharged during processing Easy and beneficial to processing.
