The application belongs to the technical field of numerical control machining, and discloses a deep hole machining method. First, a first guide hole and a pre-drilled hole with a size smaller than a designed radial size are milled by using a straight head gun drill, and then a second guide hole and a deep hole are milled by using a ball head gun drill. The straight head gun drill is used for preliminarily rough machining the pre-drilled hole, and the ball head gun drill is used for subsequent fine milling drilling. The pre-drilled hole provides a chip removal channel for cutting chips in the ball head gun drill milling process, the cutting chips can be quickly removed, the inner wall of the deep hole is prevented from being scratched, and the size precision and surface smoothness of the deep hole are ensured. Meanwhile, the pre-drilled hole can provide a guiding effect for the movement of the ball head gun drill, and the straightness of the deep hole is greatly improved.

This invention relates to the field of deep hole machining process monitoring and intelligent prediction technology, and discloses a high-temperature alloy gun drill deep hole machining parameter prediction system based on multiple sensors. The system includes a deep hole drill bit, which has an internal flow channel cutting fluid supply module extending to the cutting zone. This module includes a high-pressure pump, a rotary joint, and a fluid supply pipeline connecting to the internal flow channel. The high-pressure pump pressurizes the cutting fluid to a pressure range within the internal flow channel where the cutting fluid is in a cavitation-free, continuous flow state. By multiplexing the cutting fluid from a simple cooling / chip removal medium into a continuous liquid acoustic transmission channel, the transmission attenuation rate of high-frequency acoustic pressure waves in the cutting zone within the 15 MPa high-pressure cutting fluid is less than 15%, while the attenuation rate of signals in the same frequency band via traditional transmission paths exceeds 85%. The signal-to-noise ratio of the core acoustic signature frequency band is improved compared to traditional methods, providing a high-quality raw data foundation for the backend AI model.

A smart cabinet structure for deep hole gun drills includes a smart cabinet body, a PLC module, an industrial control module, and a cloud platform.
