Cutting heat dissipation of deep hole drilling and boring machine

As a commonly used machine tool operating equipment,  deep hole drilling and boring machines are becoming more and more popular. You know the use of deep hole drilling and boring machines below, let's take a look below:

According to the situation of deep hole drilling and boring machine manufacturers, deep hole processing is in a closed or semi-closed state, and the cutting conditions of the tool cannot be directly observed. At present, based on experience, we can judge whether the cutting process is normal by listening to sounds, watching cutting, observing machine tool load and pressure gauge, and touching vibration.

Cutting heat dissipation. According to the introduction of deep hole drilling and boring machine manufacturers, 80% of the cutting is taken away during general cutting and hot cutting, and only 40% of deep hole drilling tools, which account for a large proportion of cutting heat and diffusion,  which delays blade overheating and the temperature reaches 600 degrees. Forced cooling must be used.

芯片 Deep hole drilling this chip is not easy to discharge.  Due to the depth of the hole, the chip has a long stroke and is easy to block, which causes the drill to collapse. Therefore, the length and shape of the chip should be controlled, and forced chip removal should be performed.

The stiffness of the process system is poor. Due to the size of the hole, the length of the hole is large, the length of the drill pipe is thin and long, the rigidity is poor, the vibration is easy to occur, and the drilling is easy to deviate. Therefore, the support guidance is extremely important.
