The configuration selection of slant bed CNC lathe will directly affect its processing performance and scope of application. The following is an introduction to configuration selection from entry-level to high-end:
1. Entry-level configuration
A. Control system: You can choose control systems such as GSK. This type of system has a simple operation interface, relatively simple programming, and a relatively affordable price. It is suitable for beginners and small processing companies or personal workshops that do not require particularly high processing accuracy.
B. Spindle motor: Generally equipped with an ordinary three-phase asynchronous motor with a power of about 3-5.5kW. It can meet the low-speed cutting processing needs of general materials, such as simple parts processing of aluminum, copper and other materials.
C. Guide rail: Ordinary rectangular guide rails are used. The structure is simple, the cost is low, and it has a certain load-bearing capacity, but it is relatively limited in terms of motion accuracy and speed. It is suitable for occasions with small processing loads and low precision requirements.
D. Tool holder: Usually equipped with a four-station or six-station electric tool holder. The tool change speed is relatively slow, but it is sufficient to meet the needs of simple processing procedures, and it is cheap and easy to maintain.
2. Intermediate configuration
A. Control system: Fanuc 0i-Mate, Siemens 808D and other systems can be selected. These systems are powerful, with rich instruction sets and perfect programming functions, and can realize more complex parts processing, while having good stability and reliability.
B. Spindle motor: Equipped with 7.5-11kW servo spindle motor. The servo motor has better speed regulation performance and precision control ability, can achieve higher cutting speed and feed speed, and is suitable for processing a variety of materials, such as steel parts, cast iron parts, etc.
C. Guide rail: Linear rolling guide rail is adopted. It has the advantages of small friction coefficient, high motion sensitivity, high positioning accuracy, and can withstand large subversion torque. It can keep good stability when the machine tool moves at high speed, and is suitable for processing parts with medium precision requirements.
D. Tool holder: Eight-station or twelve-station hydraulic tool holder is often used. The tool change speed is fast and the precision is high. It can meet the multi-process processing requirements of more complex parts and improve processing efficiency.
3. Advanced configuration
A. Control system: It is recommended to use high-end CNC systems such as FANUC 31i-MB and Siemens 840D sl. These systems have powerful computing power and complex control functions, support advanced functions such as five-axis linkage, high-speed cutting, and intelligent processing, and can be used to process high-precision and complex-shaped parts, such as aerospace parts, precision molds, etc.
B. Spindle motor: Use high-power, high-speed electric spindles of 15-30kW and above. The electric spindle integrates the motor and the spindle, has higher speed and precision, can achieve high-speed cutting and precision processing, and is suitable for processing high-strength and high-hardness materials.
C. Guide rails: Use high-precision hydrostatic guide rails or air-floating guide rails. This type of guide rail has extremely high precision and rigidity, can provide friction-free and wear-free movement, and ensure the stability and reliability of the machine tool during high-speed and high-precision processing, but the cost is relatively high.
D. Tool holder: A power turret with an automatic tool changer (ATC) can be configured. The power turret can not only realize the automatic exchange of tools, but also provide power-driven tools for milling, drilling and other processing operations, greatly improving the processing capacity and flexibility of the machine tool.
E. Other configurations: It can also be equipped with high-precision measurement systems, such as laser measuring instruments and contact probes, to achieve online measurement and precision compensation of parts; adopt high-performance cooling systems and chip removal devices to ensure the cooling effect during processing and the cleanliness of the working environment.
The configuration selection of the inclined bed CNC lathe needs to comprehensively consider the processing needs, budget and future development. From entry-level to high-end configurations, the functions and performance of the equipment are gradually improved, suitable for different application scenarios.
