CNC lathe is a high-precision, high-efficiency automated machine tool, and its components usually include the following key parts:
1. Machine tool body
The machine tool body is the main structure of the CNC lathe, mainly composed of bed, spindle box, feed transmission system, tool holder, tailstock, center frame, etc.
Bed: The bed is the basic component of the CNC lathe, bearing the weight and workload of the entire machine tool. It is usually made of high-strength cast iron or cast steel materials, with good rigidity and stability.
Spindle box: The spindle box is the main transmission component of the CNC lathe, including transmission devices such as the spindle and motor. The model, speed and power of the spindle directly affect the processing capacity of the lathe.
Feed transmission system: The CNC lathe feed transmission system consists of transmission components such as the X-axis and Z-axis, which are responsible for controlling the feed movement of the tool on the workpiece. High-precision transmission devices such as servo motors and ball screws are usually used to ensure the accuracy and stability of the feed movement.
Tool holder: The tool holder of a CNC lathe is a component that supports and fixes the turning tool, and usually has functions such as automatic tool holder feeding and crank stroke. The structure of the tool holder and the number of tool holders determine the workpiece processing capacity of the lathe.
Tailstock and center frame: The tailstock of a CNC lathe is used to support one end of the workpiece, and the center frame is used to support the middle of the workpiece to ensure the stability and accuracy of the workpiece during processing.
2. Control system
The control system is the core component of the CNC lathe, which consists of electrical, hydraulic and pneumatic components, program control devices, etc. By writing CNC programs, the control system can automatically control various parts of the machine tool and realize various complex parts processing.
CNC system: The CNC system is the brain of the CNC lathe, responsible for receiving digital information on the control medium, and after compilation, calculation and logic processing, it outputs various signals and instructions to control the orderly movement of various parts of the machine tool.
Servo system: The CNC lathe servo system receives the pulse signal from the CNC system and converts it into the movement of the moving parts of the lathe to process parts that meet the requirements of the drawing. The servo system of CNC lathe usually adopts closed-loop control, which has the characteristics of high precision and high stability.
Control medium: The control medium of CNC lathe is the program carrier that transmits the part processing information to the CNC device, including CRT operation panel, lathe operation panel and storage medium.
3. Auxiliary device
The auxiliary device is an important part of the CNC lathe. It is used to receive the instruction information such as main motion speed change, tool selection and exchange, auxiliary action, etc. output by the CNC device. After necessary compilation, logical judgment, and power amplification, it directly drives the corresponding electrical, hydraulic and mechanical components to complete various prescribed actions.
Cooling system: The cooling system of CNC lathe is used to cool the cutting area to prevent overheating during the cutting process, affecting the processing accuracy and tool life.
Lubrication system: The lubrication system of CNC lathe is used to lubricate the various moving parts of the machine tool to reduce friction and wear, and improve the service life and processing accuracy of the machine tool.
Chip removal system: The chip removal system of CNC lathe is used to discharge the chips generated during the cutting process from the machine tool in time to keep the inside of the machine tool clean and tidy, and prevent the chips from affecting the processing accuracy and surface quality.
In summary, CNC lathes are composed of multiple parts, including the machine tool body, control system, and auxiliary devices. These parts cooperate and work in coordination with each other to achieve the high-precision, high-efficiency, and high-automation processing capabilities of CNC lathes.
