1. Ensure the coaxiality of drill pipe support (with drill bar support sleeve on it), tool guide sleeve and headstock spindle and drill box spindle.
2. Stepless adjustment of feed speed.
3. Sufficient pressure, flow and clean cutting fluid system.
4. Deep hole tool guide system. A deep hole drilling machine in which the workpiece rotates (or the workpiece and tool rotate at the same time) is similar to a horizontal lathe. Deep hole drilling machines are universal, special and refitted by ordinary lathe. In order to facilitate cooling and chip removal, the layout of deep hole drilling machines is horizontal, and the main parameter of deep hole drilling machines is large drilling depth. The deep hole honing machine tool has safety control and indication devices, such as spindle load (torque) meter, feed speed meter, cutting fluid pressure meter, cutting fluid flow control meter, filter controller and cutting fluid temperature monitoring. Before drilling into the workpiece, the deep hole cutter is guided by the cutter to ensure the accurate position of the cutter head, and the guide sleeve is close to the end face of the workpiece.
5. It has safety control indication devices, such as spindle load (torque) meter, feed speed meter, cutting fluid pressure gauge, cutting fluid flow control meter, filter controller and cutting fluid temperature monitoring, etc. Deep hole cutters are suitable for boring and rolling in machine tool manufacturing, locomotive, ship, coal machine, hydraulic, power machinery, pneumatic machinery and other industries, so that the workpiece roughness can reach 0.4-0.8 μ m。
