What is the difference between a deep hole drill and a gun drill? Deep hole drills are divided into gun drills, single pipe drills and jet suction drills. Therefore, gun drills belong to deep hole drills. There are two types of deep hole drills: gun-drilling deep hole drills and blade-type deep-hole drills. The blades of deep hole drills are interchangeable.
The body of a deep hole drill can be used permanently and the blade can be replaced. The gun-drilling deep-hole drill and the blade-type deep-hole drill both use oil feeders for cooling fluid, and can drill deep holes on solid materials such as carbon steel and alloy steel, with an aspect ratio of up to 1: 100. Special deep hole machining tool for chip removal. The v-shaped angle is 120 °. Application of gun drill special machine tools.
The cooling and chip removal method is a high pressure oil cooling system. The oscillating drilling skill is a relatively common deep hole drilling method announced in the cutting theory and oscillating theory, which belongs to a type of oscillating cutting. Oscillation drilling skills are based on general drilling methods, applying a certain amplitude and frequency of oscillation to the tool or workpiece, and then changing the touch connection between the tool and the workpiece.
The difference between it and the general drilling method is that the oscillation drilling technique introduces relative motion through the equipment to excite the device between the workpiece and the tool, and then affects the cutting amount, making the deep hole drilling process a pulsed time-cut-time-off This cutting process has excellent technological effects, which is why it has attracted many scholars at home and abroad to study it.
During the cutting process of the tool, the tool and the workpiece are periodically touched and disengaged. The direction and size of its movement speed are also constantly changing. These characteristics of the oscillating drilling skill are dealing with difficult machining processes or difficult to process data, such as In the processing of small and fine ultra-long holes, it is difficult to compare the general drilling skills, such as extended tool life, reduced cutting temperature, reduced cutting force, increased machining accuracy, decreased cutting temperature, etc., which makes drilling There has been a qualitative leap in processing skills.
