The continuous development of science and technology has led to the progress of all walks of life. In terms of machinery, the use of deep hole drills is quite extensive. Deep hole drilling machine tools are indispensable mechanical products in deep hole machining. What are the characteristics of deep hole drilling machine tools? If you don't know, follow the small series to see. 1. The arbor is limited by the aperture. The diameter is small and the length is large, resulting in poor rigidity and low strength. It is easy to generate vibration, corrugation and taper during cutting, and affects the straightness and surface roughness of the deep hole. 2. When drilling and reaming, the cooling lubricant is difficult to input into the cutting zone without special equipment, which reduces the durability of the tool and makes chip removal difficult. 3. In the process of deep hole processing, it is not possible to directly observe the cutting condition of the tool. It can only be judged by the working experience listening to the sound during cutting, looking at the chip, the vibration of the hand and the temperature of the workpiece, and the instrument (oil pressure gauge and electricity meter). Whether the cutting process is normal. 4, chip removal difficulties, must use reliable means to break the chip and control the length and shape of the chip, in order to facilitate the smooth elimination, to prevent chip blockage. 5. In order to ensure the smooth running of the deep hole during the processing and to achieve the required processing quality, the inner (outer) chip removal device, the tool guiding and supporting device and the high pressure cooling lubrication device should be added. Generally, the hole depth is more than 3 to 5 times of the hole diameter. It is called a deep hole. It is difficult to use a twist drill in the hole of the chip and the cooling hole. For the smooth chip removal, the iron chip should become a thin strip. Come out and bring out smaller pieces, while the coolant is easy to enter. The grinding method of the bit can be carried out by a relatively simple grinding method. 1, the angle of the cutting edge is increased to 130-140 degrees to increase the chip thickness and change the direction of chip discharge (the direction of chip discharge is perpendicular to the cutting edge) 2. Grinding the chisel edge to reduce the axial cutting edge while the cutting edge produces a corner at the core to facilitate chipping. 3. If the drill diameter is large, the chip flute can be ground on one side edge. To be wider, the cutting force of the two cutting edges can be balanced. 4. Pour 1 mm and 45 degrees from the outer edge of the cutting edge to reduce wear and improve finish. 5. The drilling speed is slightly lower, and the feed amount should be larger, so that the chips are thickened and discharged in strips. 6. The nozzle of the coolant should face the hole inward to facilitate the coolant entering the cutting area. When the hole ratio is more than 8 times larger than the batch size, it is best to drill holes in the special deep hole drilling machine. The effect is very high. I have tried to produce the lathe spindle diameter 32 length of about 850 mm material 45 steel for only 13 minutes. Deep hole drilling is divided into two types: external chip removal and internal chip removal; Smaller diameters use external chip removal, because the drill pipe is too small to remove the chip. The hole with larger diameter has sufficient space for chip removal. The high pressure oil is pressed between the hole wall and the drill pipe to cut the chips. The heat is discharged from the rod. The drill bit is specially made of hard alloy, which is divided into two parts: the guide and the chip edge. The chip is sharpened into a trapezoidal shape to divide the chip. The height and width of the chip breaker depend on the material and feed of the workpiece. The amount is preferably such that the chip shape is a tight C-shape or a tile shape.
