Machining center, also known as CNC machining centers, is the development of machinery and equipment from the CNC milling machine, is a milling machine controlled by electronic meter digital signals, but it is different from ordinary CNC milling machine, it has the ability to automatically exchange machining tools, can be installed in the tool magazine by the tool for different purposes, can be installed in a clamping through the automatic tool changer to change the spindle The machining tool on the spindle can be changed by the automatic tool changer in one clamping to realize a variety of machining functions.
The machining center is a general CNC milling machine on the basis of the development of a kind of automatic machining equipment, its machining function is very strong, not only the adaptability of parts processing, good flexibility, but also can be processed by ordinary machine tools can not be processed or very difficult to process the parts, machining precision, processing quality is stable and reliable, in the field of high-end equipment manufacturing industry is widely used.
Two, CNC machining center is to do
Machining center is widely used in the manufacturing industry, a processing equipment, a lot of manufacturing industry can not do without the machining center.
CNC machining centers mainly do some precision parts processing, and can achieve multi-axis linkage processing, processing ABS, PC, PE, POM, PP, acrylic, nylon, bakelite, silicone rubber, aluminum alloy, zinc alloy, magnesium alloy, titanium alloy, steel, copper, stainless steel, sheet metal and other materials, mainly used in automotive and motorcycle parts, lighting, automation robot, Mechanical hardware, aerospace and military, electronic instruments, medical equipment, 3C digital, household appliances, communications and cell phone industries.
Three, what is the classification of machining centers
There are many types of machining centers, according to different classification methods can be divided into different types:
1, according to the state of the spindle in the space
(1) Vertical machining centers: machining centers with the spindle in the space is in a vertical state.
(2) Horizontal machining center: the spindle is in a horizontal state in space.
(3) Vertical and horizontal machining centers: the spindle can be converted vertically and horizontally, also known as five-face machining centers, composite machining centers.
2, according to the number of machining center column points
Can be divided into single-column machining centers and double-column (gantry) machining centers.
3, according to the number of coordinates of the machining center movement and the number of coordinates controlled at the same time
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. Three-axis, four-axis refers to the machining center has the number of coordinates of the movement, linkage refers to the control system can simultaneously control the number of coordinates of the movement, so as to achieve the position of the tool relative to the workpiece and speed control.
4, according to the number and function of the table
There are three kinds of single-bench machining centers, double-bench machining centers and multi-bench machining centers.
5, according to the machining accuracy
(1) ordinary machining centers: resolution of 1μm, the maximum feed rate of 15 ~ 25m/min, positioning accuracy of l0μm or so.
(2) high-precision machining centers: resolution of 0.1μm, the maximum feed rate of 15 to 100m/min, positioning accuracy of about 2μm.
