Due to the limited space for chip and chip屑 in deep hole drilling machines, chip ejection is difficult. A slight oversight can lead to holes in the chips, excessive friction on the cutting edges, and damage to the drill bits, affecting the precision of the hole diameter.

During deep hole drilling operations, the coolant often struggles to reach the cutting zone, leading to insufficient dissipation of cutting heat. This results in excessive heat accumulation on the drill tool, thereby reducing the lifespan of the deep hole drilling machine's cutting tools.

3. Due to the long and slender cutting tools of deep hole drilling machines, their rigidity is poor, and high-speed rotation tends to cause vibration and deviation in the drilling process, resulting in the hole center being misaligned.

Deep hole boring machines represent advanced hole processing technology, offering precise and dimensionally accurate hole placements with excellent straightness, concentricity, surface finish, and repeatability, all achievable through a single cutting pass. They facilitate the processing of various deep hole configurations, including cross holes, oblique holes, blind holes, and flat-bottom blind holes. Not only are they suitable for processing deep holes with large length-to-diameter ratios (up to 300:1), but they can also handle shallow holes, with the smallest drilling diameter reaching 0.7mm.
