Deep in the general machine tool, tool rigidity as bad, easy to lead in the deep processing of partial to the hole axis line skew the discharge of chip and tool cooling is also more difficult and is difficult to guarantee the required machining accuracy and surface roughness degree. And converted into a deep hole with lathe machines, because of its low cost and short manufacturing cycle, and more than one use (deep hole drilling, turning, deep hole boring and honing), etc, has been accepted by many manufacturers. This realization is the use of ordinary lathe processing deep hole, using Lathe complete processing of the hole. Converted into a deep hole machine tool lathe main machine and two major oil line. Machine mainly consists of a center frame, granted the three major oil players and coupling components; oil line into the oil with some of the major device, back to asphalt and chip removal boxes, fuel tank
