Deep Hole Parts Processing Technology Features
Dec 19, 2018


Compared with general parts processing, deep hole parts processing has the following process characteristics:


  1. The quality requirements of deep hole parts are high, the dimensional accuracy is in the range of IT6-IT12, and the surface roughness Ra is in the range of 25-0.2μm.


2. The inner surface of the deep hole part is processed in a semi-closed state. The operator cannot directly observe the cutting condition of the tool. In addition, the chip space is small, the cutting heat is not easily dissipated, and the chip removal and cooling lubrication are difficult.


3. The process system is weak. The processing stability is low, vibration and deformation are easy to occur, and the processing precision and surface roughness of the hole are not easily ensured.


4. The cutting distance is long, the chip discharge is difficult, the cutting edge of the tool is unevenly loaded, the cutting temperature is high, and the tool is easy to wear, crack and chip.
