In order to meet the requirements of deep processing technology Boring, deep hole boring machine shall meet the following conditions: 1) ensure that the drill stand (on which the drill pipe support sleeve), the tool guide sleeve and the headstock spindle and the drill spindle box concentricity. 2) stepless adjustment of the feed velocity. 3) sufficient pressure, flow and clean cutting fluid systems. 4) having a safety control indicating means deep boring processing, such as spindle load (torque) of the table, the table feed rate, cutting fluid pressure gauge, cutting fluid flow control table, filtered cutting fluid controller and temperature monitoring. 5) tool guidance system. Before the drill hole into the workpiece by the exact position of the tool tip guide guaranteed spot Boring, guide sleeve against the end face of the workpiece. Boring boring tool is mainly used in the workpiece boring machine, usually spiral Boring, boring tool rotation-based movement, boring tool or workpiece movement of the feed movement. Its precision and surface quality than drilling. Boring is the main equipment for processing large box of parts. Processing characteristics: processing a workpiece does not move, so that the tool moves, the tool center alignment hole center, and rotation of the tool (main motion).
