Principle of CNC lathe processing

Basic Principle:
A CNC lathe is a machine tool that uses digital control technology to automatically control the movement and processing of the lathe. It reads the pre-written processing program through the CNC system (CNC), converts the digital instructions into the movement and action of each coordinate axis of the machine tool, controls the relative movement between the tool and the workpiece, and thus realizes the precise processing of the workpiece.
Components:Host: including mechanical parts such as the bed, spindle box, tool holder, tailstock, etc., is the basic structure of the lathe, providing the movement and support functions of the machine tool.
CNC system: It is the core of the CNC lathe and consists of hardware and software. Hardware includes computers, input and output devices, controllers, etc.; software includes system programs and user programs, which are used to control and manage the machine tool.
Servo system: It consists of servo motors and servo drivers. According to the instructions issued by the CNC system, it accurately controls the movement speed and position of each coordinate axis of the machine tool to ensure the processing accuracy.
Auxiliary devices: such as cooling systems, lubrication systems, chip removal devices, etc., provide necessary support and guarantee for the normal operation and processing of the machine tool.
Processing characteristics
High precision: It can achieve high-precision processing, and the processing accuracy can usually reach the micron level, which is suitable for processing parts with high precision requirements.
High efficiency: It can automatically complete multiple processing steps, reduce manual operation and auxiliary time, and improve production efficiency. At the same time, CNC lathes can also realize multi-axis linkage processing to further improve processing efficiency.
High flexibility: You can easily realize the processing of different parts by simply changing the processing program. It is suitable for the processing of single pieces, small batches and complex shape parts, and has strong flexibility and adaptability.
Strong ability to process complex shapes: It can realize the processing of various complex curves and surfaces through programming, and can process part shapes that are difficult to complete with traditional lathes.Vertical machining centers are widely used, and their advantages of high machining accuracy and high efficiency are unmatched by ordinary machine tools. Vertical machining centers are made of high-grade cast iron, and are strictly treated with natural aging and stress relief processes to ensure the accuracy of the machine tool and the stability of machining performance. When customers choose, our machining center manufacturers generally make reasonable recommendations based on the customer's processing requirements and materials. The prices of machining centers with different configurations are also very different. There are many factors that determine the price of a machining center. As a user, you need to understand what parts are available for a vertical machining center? Let us introduce them to you for reference: Optional parts for vertical machining centers: 1. System: Common ones include FANUC/Mitsubishi/Siemens/New Generation/Kenti/Guangsu systems. 2. Tool magazine: bamboo hat-style tool magazine or disc tool magazine (that is, robot tool magazine). 3. Screw: Taiwan Hiwin high-precision ball screw or domestic brand screw. 4. Fourth and fifth axes: optional. 5. Chip remover: chain plate type or spiral type.

The brand of the tool-mounting spindle of the vertical machining center is also an important optional component. With the optimization of workpiece materials and the improvement of machining accuracy requirements, there are many applications for high-speed and high-power electric spindles. After being equipped with a series of related devices to control the spindle constant temperature and vibration function, the safety and reliability of the high-speed operation are greatly guaranteed. The advantages of the electric spindle are obvious, with small vibration and less thermal deformation. Independent cooling device is used to control the constant temperature of the rotating axis C axis, B axis, tool-mounting electric spindle and cutting oil. The core constant temperature control system and the superior spindle circulation internal cooling system ensure the stability under high-speed operation and the consistency of part machining accuracy.
