1. Classification by machine tool shape
(1) Vertical machining center is convenient for clamping workpieces, easy to operate, easy to observe machining conditions, easy to debug programs, and widely used. However, due to the limitations of the column height and tool changing device, parts that are too high cannot be processed; When machining cavities or concave surfaces, it is difficult to remove chips, and in severe cases, it can damage the tool, damage the machined surface, and affect the smooth progress of machining; The structure of vertical machining centers is simple, occupying a small area, and the price is relatively low. Therefore, it is suitable for processing workpieces with relatively small dimensions in the height direction. There are generally two ways to change tools in machining centers: using a robotic arm to change tools and using a tool library to change tools.
(2) A horizontal machining center has its spindle centerline set in a horizontal state. It is not suitable to observe the horizontal machining center during program debugging and trial cutting, making it inconvenient to monitor during machining, and inconvenient for part clamping and measurement; Compared with vertical machining centers, horizontal machining centers have a complex structure, occupy a large area, and are also more expensive; But it is easy to remove chips during processing, which is beneficial for processing.
(3) Gantry machining center
(4) Five sided machining center
2. Classification based on 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, etc.
3. Classification by number and function of workstations
Machining centers can be divided into single table machining centers, double table machining centers, and multi table machining centers.
Four points to pay attention to when using a drilling machine in a large iron drilling center:
Drilling machine refers to the mechanical and equipment that uses harder and sharper tools than the target object to leave cylindrical holes or holes in the target object through rotary cutting or rotary extrusion. It is also known as drilling machine, drilling machine, drilling machine, through hole machine, etc.
1: The drilling machine should be packed in a specially designed packaging box to avoid vibration and collision with each other.
2: When in use, remove the drill hole from the packaging box and immediately place it in the spring clamp of the spindle or the tool library for automatic replacement of the drill bit. Put it back into the packaging box immediately after use.
3: The drilling machine manufacturer should use non-contact measuring instruments such as tool microscopes to measure the drilling diameter, in order to avoid contact between the cutting edge and the mechanical measuring instrument, which may cause damage.
