Simply put, the commonly used tool alignment methods for drilling and CNC machining centers include tool alignment instruments, active tool alignment, and trial cutting methods.
Due to the fact that the complete machining process of a workpiece may involve several or even dozens of cutting tools, trial cutting methods are relatively primitive and have poor tool accuracy, so they are rarely used. Let's first take a look at the first two typical knife alignment methods:
1. Active tool alignment method: Utilizing the tool detection function of the CNC machining center to achieve active tool alignment. This device can actively and accurately measure the length of each tool in each coordinate direction, and actively correct the tool error value. The entire detection and calibration process can be completed on the basis of normal operation of the machine tool. This tool alignment method relies entirely on electronic control equipment, eliminating manual tool alignment errors, resulting in higher accuracy and better tool alignment power.
2. Tool alignment method: Choose the tool alignment device for tool alignment. Due to its high economic efficiency, it is the main tool setting method for CNC machining centers. There are two types of knife alignment: internal knife alignment device and external knife alignment device. The demand for an off-site tool presetter should be corrected in advance outside the machine tool, and it can be used after being installed on the machine tool; In machine tool presetter is a method of directly measuring cutting tools at a fixed position on a machine tool.
In order to change tools in CNC machining centers, not only can the tool holder be used, but also the tool magazine can be used to achieve the tool change process. The main power of the tool magazine comes from the transmission power provided by the motor and hydraulic system, and the positioning unit is used to ensure that every replaced tool and tool sleeve can rely on accurate stopping.
The CNC machining center is fully enclosed and protected, with centralized processes and continuous machining processes. By using multiple tools, the automatic tool changing process can be easily achieved, and by using multiple workbenches, the workbenches can be automatically replaced. Meanwhile, CNC machining centers also have strong functional support and tend towards composite machining. High degree of automation, high precision, and high sales volume. Under appropriate circumstances, greater benefits can be achieved.
According to the specific structure, it can be divided into three forms: vertical, horizontal, and portal.
The difference between CNC machining centers and other CNC machine tools is that CNC machining centers have tool libraries and automatic tool changing devices, while other CNC machine tools do not have tool libraries and automatic tool changing devices. This is the difference between CNC machining centers and other CNC machine tools, and also the advantage of CNC machining centers. With the automatic tool changing device and tool magazine, workpieces can be clamped at once without manual operation, and multiple processes can be automatically completed.
