The vertical machining center is a machining center with a vertical main spindle. Its structural model is mostly a fixed column, and the worktable is rectangular. It has no indexing expansion and rotation performance. It is suitable for processing discs, sleeves, and plate parts. It usually has three linear movable coordinates. axis, and a turntable that rotates along the horizontal axis can be installed on the workbench to process spiral parts. The vertical machining center is easy to install, easy to operate, easy to observe the 6082 aluminum machining status, simple to debug the program, and ordinary to use.
Disadvantages: Limited by the height of the column and the tool change device, parts that are too high cannot be processed. When processing the cavity or concave profile, the chips are not easy to remove. In severe cases, the tool will be damaged, the processed surface will be damaged, and the processed surface will be affected. Implement it smoothly.
Advantages: Compared with the corresponding horizontal machining center, it has a simple structure, a smaller footprint, and is lower.
Features: After the workpiece is clamped once on the machining center, the digital control system can control the machine tool to automatically select and replace tools according to different processes, automatically change the machine tool spindle speed, feed amount, and the movement trajectory of the tool relative to the workpiece and other auxiliary functions. It can complete multi-process micromachining on several sides of the workpiece in sequence. It also has a variety of tool changing or tool selection functions, which greatly improves production efficiency.
Usually there is a rotary worktable with automatic indexing. It generally has 3 to 5 motion coordinates. The common ones are three linear motion coordinates plus one rotary motion coordinate. After the workpiece is clamped in one time, the installation surface and top surface are removed. In addition to the 7075 aluminum machining of the remaining four surfaces, it is suitable for adding box-type parts. Compared with vertical machining centers, horizontal machining centers have easy chip removal during processing, which is beneficial to processing, but the structure is complex. The price is higher.
