6D drilling Revolutionary innovation in drilling technology
Principles of vibration assisted drilling Conventional and vibration assisted drilling in direct comparison
The basic difference between the two drilling processes can be seen in the geometry and size of the chip. With conventional drilling, a long spiral ship is created. With vibration drilling, the chip is constantly broken off by superimposing the rotary motion with an axial oscillating motion, resulting in the creation of lots of small chips.
One significant advantage of vibration drilling is the substantially lower thermal load on the drilling tool and on the raw material. An analysis of the drilling process using an infrared camera clearly illustrates the advantages of vibration drilling. With conventional drilling, the temperature rises as the drilling depth increases. With vibration drilling, the processing temperature is significantly lower and remains constant as the drilling depth increases, since the chips do not create friction.
