CNC cylindrical grinder can achieve high-precision machining
Date: 2025-12-21Read: 6
CNC cylindrical grinder is a machine tool controlled by a CNC system, widely used in the field of mechanical processing, especially in precision machining. It is mainly used for grinding the outer circle of shaft parts, ensuring high-precision dimensions and surface quality. The emergence of cylindrical grinding machines has greatly improved machining efficiency and product quality, especially in high demand machining applications such as aerospace, automotive, precision instrument and other industries, playing an irreplaceable role. The working principle is to achieve precision grinding of the outer surface of the workpiece by continuously cutting through the high-speed rotating grinding wheel in contact with the outer surface of the workpiece. During the machining process, the workpiece is fixed on the worktable and its movement is controlled by a feed system, while the grinding wheel comes into contact with the workpiece surface through high-speed rotation of the spindle. The rotation direction of the grinding wheel is opposite to the feed direction of the workpiece, effectively removing excess metal on the surface of the workpiece and achieving the goal of precision machining.
The grinding process is divided into three stages: coarse grinding, fine grinding, and ultra fine grinding. The rough grinding stage mainly removes most of the excess on the surface of the workpiece, while the precision grinding stage further refines the accuracy of the workpiece surface. Finally, in the ultra precision grinding stage, the grinder can achieve micrometer level precision control to ensure the ultra-high surface quality of the workpiece.
CNC cylindrical grinderCharacteristics:
1. High precision: Through precise control of the CNC system, high-precision machining can be achieved. By precise feed control and grinding parameter settings, the dimensional accuracy and surface quality of the workpiece can be ensured.
2. High automation: With a high level of automation, it can automatically complete multiple processes such as feed, grinding, and adjustment of workpieces, reduce manual operations, and improve production efficiency and processing quality.
3. Multifunctionality: It has multiple processing functions, such as conventional outer circle grinding, inner circle grinding, end face grinding, etc. By replacing different grinding wheels and tools, various grinding tasks of different shapes and sizes can be completed.
4. Flexibility: Able to program and adjust flexibly according to the requirements of different workpieces, adapting to the processing of workpieces with different specifications and materials. This gives the cylindrical grinder significant advantages in single piece and small batch production.
5. Stability: Adopting a high rigidity and high-precision structural design, it has high stability and can maintain machining accuracy during long-term continuous work.
Application of CNC cylindrical grinder:
1. Automotive manufacturing: commonly used for the processing of automotive components, such as shaft parts, gears, etc. The machining accuracy of automotive components directly affects the performance and safety of the entire vehicle, which can meet this requirement.
2. Precision instruments: The precision instrument industry has strict requirements for the machining accuracy and surface quality of components, and high-precision grinding can meet the needs of this industry.
3. Mold manufacturing: It is also widely used in the field of mold manufacturing, especially in the manufacturing of plastic molds, stamping molds, etc., which can ensure the accuracy and smoothness of the mold surface.
