Point-to-point CNC machine is a CNC machine with a specific working mode.
Its basic feature is to control the CNC system through a program, so that the tool can move accurately from one point to another or from one surface to another without having to care about the intermediate motion trajectory.
This type of machine is mainly used for single-point cutting of parts with a certain contour, so it is also called "point-to-point CNC machine".
Basic composition
Point-to-point CNC machine generally consists of the following main parts:
Machine body: responsible for carrying the workpiece, which is the basic structure of the machine.
CNC system: responsible for controlling the movement of each axis of the machine, which is the "brain" of the machine.
Actuator: responsible for converting the commands issued by the CNC system into actual machine movement, such as tool movement, rotation, etc.
Sensor: responsible for detecting the movement of each axis of the machine to ensure the movement accuracy and stability of the machine.
Tool detection system: responsible for real-time monitoring of tool wear, tool breakage, etc. to avoid unexpected situations during processing.
Working principle
The basic working principle of point CNC machine tools is to control the CNC system through the program to realize the motion control of each axis of the machine tool, so as to realize high-precision processing of the workpiece. During the processing, the CNC system sends control signals for each axis according to the pre-compiled processing program, so that the actuator can perform corresponding movements. The actuator converts the control signal into the movement of each axis on the machine tool to realize the positioning, movement, rotation, feeding and other operations of the workpiece. At the same time, the sensor monitors the movement of each axis of the machine tool in real time and feeds back to the CNC system to ensure the movement accuracy and stability of the machine tool.
Application field
Point CNC machine tools are widely used in the manufacturing industry, especially for those occasions that require high-precision single-point cutting. For example, in the fields of aviation, electronics, instruments, and instruments, it is often necessary to process some parts with complex contours. At this time, point CNC machine tools can play their advantages of high precision and high efficiency.
Precautions
Although point CNC machine tools have the advantages of high precision and high efficiency, some problems need to be paid attention to during use. For example, it is necessary to regularly maintain the machine tools to ensure the normal operation of each component; at the same time, it is also necessary to provide professional training for operators to ensure that they can master the machine tool operation skills and improve processing efficiency and quality.
In summary, the point CNC machine tool is a high-precision and high-efficiency CNC machine tool that achieves high-precision processing of workpieces through program control. It has broad application prospects and development space in the manufacturing industry.
