How To Smoothly Carry Out Deep Hole Drilling And Achieve The Required Machining Quality During The Machining Process

     The continuous development of technology has driven progress in various industries. In terms of machinery, deep hole drills are widely used. In the process of deep hole drilling, problems such as dimensional accuracy, surface quality, and tool life of the machined parts often occur. How to reduce or even avoid these problems is an urgent problem we need to solve. Below are five common problems and solutions in deep hole machining to ensure that deep hole drills can proceed smoothly and achieve the required processing quality
1. The tool holder is limited by the aperture, with a small diameter and a large length, resulting in poor rigidity and low strength. During cutting, it is prone to vibration, ripples, and taper, which affect the straightness and surface roughness of the deep hole.
2. When drilling and expanding holes, it is difficult to input cooling lubricant into the cutting area without using special devices, which reduces the durability of the tool and makes chip removal difficult.
3. In the process of deep hole drilling, it is not possible to directly observe the cutting situation of the tool. Only by listening to the cutting sound, observing the chips, touching the vibration with hands, and observing the workpiece temperature instruments (oil pressure gauge and electric meter) based on work experience can we judge whether the cutting process is normal.
4. It is difficult to remove chips, and reliable methods must be used to break and control the length and shape of chips, in order to facilitate smooth removal and prevent chip blockage.
5. In order to ensure the smooth progress of deep hole drilling during the machining process and achieve the required machining quality, it is necessary to add chip removal devices inside (or outside) the tool, tool guidance and support devices, and high-pressure cooling and lubrication devices.
