1) Ensure the coaxiality of the drill pipe bracket (with the drill pipe support sleeve on it), the tool guide sleeve, the headstock spindle and the drill pipe box spindle. The guide rail of the bed of the deep hole drill adopts the double rectangular guide rail suitable for the deep hole machining machine, which has large bearing capacity and good guiding accuracy; the guide rail has been quenched and has high wear resistance. Deep hole drills are used to process deep holes with an aperture ratio (D/L) of more than 1:6, such as deep holes in parts such as gun barrels, gun barrels and machine tool spindles.

2) Stepless adjustment of the feed movement speed.

3) Sufficient pressure, flow and clean cutting fluid system.

4) The deep hole drill has safety control indicating devices, such as spindle load (torque) gauge, feed speed gauge, cutting fluid pressure gauge, cutting fluid flow control gauge, filter controller and cutting fluid temperature monitoring, etc.
