What Are The Precautions For Deep Hole Processing?
Dec 11, 2021
No matter what we are processing, there are corresponding precautions, especially for deep hole processing. Deep hole drilling will introduce you to the precautions for deep hole processing. I hope you can read our article carefully.
1. The tool holder is limited by the aperture, with small diameter and large length, resulting in poor rigidity and low strength. It is easy to produce vibration, ripple, and taper during cutting, which will affect the straightness and surface roughness of the deep hole.
2. When drilling and reaming, it is difficult for the cooling lubricant to be input to the cutting area without special devices, which reduces the tool durability and makes chip removal difficult.
3. In the process of deep hole machining, you cannot directly observe the cutting condition of the tool. You can only judge the cutting by listening to the sound during cutting, watching the chips, hand vibration and workpiece temperature, and observing the meters (oil pressure gauge and electric meter) based on work experience. Whether the process is normal.
4. Chip removal is difficult. Reliable means must be used to break the chips and control the length and shape of the chips to facilitate smooth removal and prevent chip jams.
5. In order to ensure the smooth progress of the deep hole in the machining process and achieve the required machining quality, an internal (or external) chip removal device, a tool guide and support device, and a high-pressure cooling and lubricating device should be added to the tool.
