How to prolong the service life of Deep Hole Trepanning Head

In the process of deep hole processing, the service life of the Deep Hole Trepanning Head directly affects the processing efficiency and cost. To extend the service life of the deep hole drilling head, the following key aspects can be taken into consideration:

Reasonable selection of drill bit material: Select the appropriate drill bit material according to the characteristics of the material being processed. For example, when processing metals with high hardness, such as alloy steel, carbide drill bits can be used. They have strong hardness and wear resistance and can effectively cope with the cutting challenges of high hardness materials.

Optimize processing parameters: Accurately control cutting speed, feed rate and cutting depth. If the cutting speed is too fast, the drill bit temperature will rise sharply and aggravate wear; if the feed rate is too large, it is easy to cause uneven force on the drill bit and breakage. Generally speaking, for different materials and hole sizes, the best parameter combination is determined by experiments or reference to the processing manual.

Sufficient cooling and lubrication: Effective cooling and lubrication can reduce the temperature of the drill bit, reduce friction and wear. An internally cooled drill bit can be used to directly deliver the cutting fluid to the cutting area through the internal channel, which has a better cooling effect. The choice of cutting fluid is also very important. Oily cutting fluid has good lubricity and is suitable for fine machining; water-based cutting fluid has strong cooling properties and is often used for rough machining.

Regular maintenance: After each use, clean the chips and cutting fluid residue on the Deep Hole Trepanning Head in time to prevent corrosion. Check the wear of the drill bit regularly. Once the wear exceeds the allowable range, sharpen or replace it in time. When storing, place the drill bit in a dry and clean environment to avoid collision.
