Selection of cutting parameters for gun drills 1. Selection of cutting parameters for gun drills: The cutting line speed is confirmed based on the processed data, but gun drills generally

Common problems and solutions of drill bits for deep hole drilling Surface roughness of the hole 1. Chip adhesion: reduce cutting speed; Avoid blade breakage; Replace with cutting fluid with

Characteristics of deep hole drilling: 1. The tool holder is limited by the aperture, with a small diameter and a large length, resulting in poor rigidity and low strength. During

Compared with general parts processing, deep hole drilling mainly has the following four processing process characteristics: (1) The surface of deep hole drilling parts is machined into a semi closed

Hard alloy gun drill, as the name suggests, is a drill bit made of hard alloy. Due to its slightly longer length compared to other drill bits, it resembles a

Improving the structure of hard alloy drill bits can enhance the quality of the inner hole. 1. Grind the drill bit into a geometric shape suitable for high-speed drilling. Because
