The bed guideway adopts double rectangular guideway which is suitable for deep hole machining machine, with large bearing capacity and good guiding accuracy; the guideway has been quenched and treated with high wear resistance. It is suitable for boring and rolling processing in machine tool manufacturing, locomotive, shipbuilding, coal machine, hydraulic, power machinery, wind machinery and other industries, so that the roughness of the workpiece reaches 0.4-0.8 μm. This series of deep hole boring machine can be selected according to the workpiece in the following working forms: 1. Workpiece rotating, tool rotating and reciprocating feeding movement. 2. Workpiece rotating, tool not rotating only reciprocating feeding movement. 3. Workpiece not rotating, tool rotating and reciprocating feeding movement. 4. Workpiece not rotating, tool rotating and reciprocating feeding movement. 5. Workpiece not rotating, tool rotating and reciprocating feeding movement. 6. Workpiece rotating, tool rotating and reciprocating feeding movement. rotation, tool rotation and reciprocating feeding movement.
