What should be paid attention to when processing fine workpieces with deep hole drilling machines?

The deep hole drilling machine is mainly used for overhead fine and dense workpieces. By using special drills such as gun drills, BTA drills, jet suction drills, etc., deep holes and fine shallow holes with a length-to-diameter ratio greater than 10 are processed. Deep hole processing represents advanced and efficient hole processing technology, with the characteristics of high fineness, high efficiency and high consistency.

The main index that determines the processing performance of a deep hole drilling machine is its processing efficiency, including cutting speed and feed speed. The cutting speed is determined by the tool structure and workpiece material, usually 50-100m/min.

The feed rate is determined by the processing and technical conditions of the workpiece, and is usually 10-100mm/min. Next, we will analyze several key factors that determine the processing efficiency of deep-hole machine tools to ensure that the processing efficiency of customers' deep-hole machine tools meets the requirements.

1. Ensure the coaxiality of the drill pipe support, tool guide sleeve and headstock spindle with the drill pipe box spindle.

2. Accurately control the stepless speed regulation of the drilling machine.

3. Choose a cutting fluid with sufficient pressure, sufficient flow, and clean.
