CNC Machining Center Inner Structures

The CNC machining center is a high-efficiency automated machine tool that is composed of mechanical equipment and a CNC system and is suitable for processing complex parts. CNC machining center is currently one of the most widely used CNC machine tools in the world. Its comprehensive processing ability is relatively strong. After the workpiece is clamped, it can complete more processing content. The processing accuracy is high. For batch workpieces with medium processing difficulty, its efficiency is 5 to 10 times that of ordinary equipment, especially it can complete Many processings that cannot be completed by ordinary equipment are more suitable for single-piece processing with more complex shapes and high precision requirements or for small and medium batch production of multiple varieties. It concentrates the functions of milling, boring, drilling, tapping and cutting threads on one device, so that it has a variety of technological means. Machining centers are classified into horizontal and vertical machining centers according to their spatial position during spindle machining. Classified according to process use: boring and milling machining center, compound machining center. According to the special classification of functions, there are: single table, double table and multi-table machining center. Machining centers with single axis, dual axis, three axis and interchangeable headstock, etc.

Machining centers are often divided into vertical machining centers and horizontal machining centers according to the state of the main shaft in space. The main shaft of the machining center is vertical in space is called vertical machining center, and the main shaft is horizontal in space is called horizontal. Type machining center. The spindle can be converted vertically and horizontally, called a vertical-horizontal machining center or a five-sided machining center, also called a compound machining center. According to the number of columns in the machining center, there are single column and double column (gantry type).
 
According to the number of coordinates of the machining center movement and the number of coordinates controlled at the same time: there are three axes and two linkages, three axes and three linkages, four axes and three linkages, five axes and four linkages, and six axes and five linkages. Three-axis and four-axis refer to the number of motion coordinates of the machining center. Linkage means that the control system can control the number of motion coordinates at the same time, so as to realize the position and speed control of the tool relative to the workpiece.
 
According to the number and function of the workbenches: there are single-workbench machining centers, double-workbench machining centers, and multi-workbench machining centers.
 
According to the machining accuracy: there are ordinary machining centers and high-precision machining centers. Ordinary machining center, the resolution is 1μm, the maximum feed speed is 15~25m/min, and the positioning accuracy is about l0μm. High-precision machining center with a resolution of 0.1μm, a maximum feed speed of 15-100m/min, and a positioning accuracy of about 2μm. Among the 2~l0μm, more than ±5μm can be called precision level.
