Machining Centers In Four Different Construction Types
Machining center is one of the world's highest output and most widely used CNC machine tools. BEST PARTS has a strong comprehensive processing ability, and can complete more processing contents after a workpiece is clamped at one time. The optional lathe has high machining accuracy, and can complete batch workpieces with medium or higher difficulty. The machining production efficiency of the machining center is 5 to 10 times that of ordinary equipment, and it can complete the processing that many ordinary equipment cannot complete. For complex shapes and high-precision single-piece processing or small and medium batches of multiple varieties, engineers will follow the production process.
1. Classification by machine tool
(1) Vertical machining center
The vertical machining center is convenient for clamping workpieces and is
easy to operate. It is easy to observe the processing situation, the debugging program is easy, and it is widely used. Due to the limitation of the height of the column and the tool changing device, parts that are too high cannot be processed. Chips are not easy to remove when machining a cavity or a concave profile. In severe cases, the tool will be damaged, the processed surface will be damaged, and the smooth processing will be affected. The structure of the vertical machining center is simple. Therefore, it is most suitable for processing relatively small workpieces in the height direction.
There are generally two types of tool change methods in machining centers: tool change through a robot and tool change through a tool magazine.
(2) Horizontal machining center
Horizontal machining center is a machine tool that realizes milling processing through the mechanism of horizontally arranged spindles. Due to the horizontal arrangement of the spindle, the tool reciprocates along the side of the workpiece to promote efficient chip removal. Horizontal machining centers can also be equipped with double exchange tables to achieve unattended operation and shorten workpiece processing cycles. The centerline of its main axis is set horizontally.
The horizontal machining center is not suitable for observation during debugging and trial cutting, inconvenient monitoring during processing, and inconvenient part clamping and measurement. Compared with the vertical machining center, the horizontal machining center has a complex structure, which shows the horizontal machining center. Ability to process complex parts. The horizontal machining center is easy to remove chips during machining, which is beneficial to machining.
(3) Gantry machining center
Gantry machining center refers to the machining center where the spindle axis is perpendicular to the workbench. The Z-axis support structure of the gantry is different. The Y-axis crosses between the two columns, which increases the load and machining range of the workbench.
(4) Five-sided machining center
In addition to the difference in structure between the five-axis machining center and the pentahedron machining center, the main difference is the processing range.The five-axis machining center is not only used in aviation, aerospace, military, precision equipment, high-precision medical equipment and other industries.
2.Classify by the number of motion coordinates and the number of coordinates controlled simultaneously
The machining center can be divided into three-axis two-linkage, three-axis three-linkage, four-axis three-linkage, five-axis four-linkage, six-axis five-linkage and so on.
3. Classified by the number of workbenches and functions
Machining centers can be divided into single-table machining centers, dual-table machining centers, and multi-table machining centers.
