High Quality Cnc Lathe Machine, Entry Level Cnc Machine

High speed machining is a new and high technology facing the 21st century. It is characterized by high efficiency, high precision and high surface quality. It has been widely used in the automotive industry, aerospace, mold manufacturing, instrumentation and other industries, and has achieved significant technical and economic benefits.

HOW TO REDUCE ALUMINUM DEFORMATION

In high-speed cutting, because of large machining allowance and intermittent cutting, milling process often produces vibration, which affects the processing accuracy and surface roughness. Therefore, the NC high-speed cutting process can be generally divided into roughing, semi-finishing, angle clearing and finishing processes.

How Does Temperature Affect Accuracy in CNC

In addition to improving dynamic and static stability, this structure has a significant effect on reducing thermal deformation errors for high-speed feed. The axially fixed structure that is pre-stretched 35m in a total length of 600mm is relatively close to the temperature rise at different feed rates.

Development of a mathematical model for the prediction

Chip morphology and segmentation play a predominant role in determining machinability and chatter during the machining of different materials. At lower cutting speeds the chip is often discontinuous, while it becomes serrated as the cutting speeds are increased. It has been identified that the chip formation process has a discrete nature, associated with the periodic shearing process of the
