CNC deep hole drilling adopts advanced CNC system, multi-axis linkage to achieve various high-difficulty and high-capacity processing requirements, its processing speed is more than 6 times that of ordinary drilling machines, the processing aperture range is 2.5-32mm, and the maximum effective processing depth can reach 2 meters. The appearance components of the CNC drilling machine include the machine bed, the machine base, the machine column, the machine slide, the spindle, the operation panel and some necessary accessories. Among them, there are electrical principles, pneumatic hydraulic principles, cooling system principles and other working principles of the normal operation of the machine tool.

Deep hole drilling machines are divided into horizontal, inverted, vertical and three-coordinate structures. The machine tool has an independent and complete cutting oil high pressure, cooling and filtering system to ensure sufficient, clean and moderate temperature cutting oil supply. For easy operation, high-pressure coolant is supplied from the back end of the machine tool, and the drill bit is fixed on the spindle through a rotating clamping sleeve. The adjustment of the position in the form of workpiece rotation and tool rotation can be selected, and the way of spindle movement or table movement can also be selected. There is a chip recovery box on the machine tool, the chips are discharged from the chip conveyor, and the coolant is cooled, filtered and recycled, and a guide is installed at the front end of the chip conveyor to guide the drill bit into the workpiece surface. When the length of the drill bit is too long, it is necessary to add an auxiliary support frame for the drill pipe.

According to the arrangement of the spindle, it can be divided into horizontal deep hole drilling machine, vertical deep hole drilling machine and three-coordinate deep hole drilling machine.

According to the commonly used deep hole drilling processing systems, there are mainly gun drilling machines, BTA single-tube drilling machines, and jet drilling machines.

According to the form of motion: the workpiece rotates, the tool performs feed motion, the workpiece does not move, and the tool rotates for feed motion; when the workpiece rotates, the tool rotates in reverse and performs feed motion. The specific method used depends on the characteristics of the workpiece and the conditions of the machined holes.

According to the chip removal method: the cutting fluid passes through the hollow drill pipe, reaches the drill head for cooling and lubrication, and discharges the chips from the V-groove outside the drill and drill pipe, such as gun drilling. The cutting fluid enters between the outer wall of the drill pipe and the machined surface of the workpiece, reaches the head of the tool for cooling and lubrication, and pushes the chips out of the drill pipe. Internal chip removal methods, such as BTA drilling.

Good cooling effect. Eliminates heat generated by deformation and friction and suppresses the formation of built-up edge.

Good high temperature lubricity, reduce the wear of the blade support, and ensure that the tool maintains a good lubricating state under the high temperature of the cutting area.

Usually the hole depth is more than 3 to 5 times the diameter of the hole, which is called a deep hole. Its difficulty is in chip removal and cooling. The hole can be drilled with a twist drill. For smooth chip removal, the iron filings should be thin strips. Jump straight out and bring out smaller fragments, and the coolant can easily enter at the same time. The grinding method of the drill bit can be a relatively simple grinding method.

The included angle of the drill edge is increased to 130-140 degrees to increase the chip thickness and change the direction of chip discharge (the direction of chip discharge is perpendicular to the cutting edge). Grinding the chisel edge can reduce the occurrence of a chamfered angle at the same time the cutting edge of the axial cutting tool is close to the drill core to facilitate chip separation.

If the drill diameter is larger, the chip groove can be ground on one side of the cutting edge, and it should be wider to balance the cutting force of the two cutting edges. If the diameter is large, the two chip grooves can be ground. Chamfer a 1mm 45° angle on the outside corner of the cutting edge to reduce wear and improve finish. The rotation speed of the drilling is slightly lower, and the feed amount should be larger, so that the chips are thickened and discharged in strips.

The coolant nozzle of the deep hole drilling should face the hole inward so that the coolant can enter the cutting area. When the hole diameter is more than 8 times larger than the batch, it should be drilled on a special deep hole drilling machine, which is very efficient.

Machine tool structure: Vertical drilling machine: a drilling machine in which the spindle box and the worktable are arranged on the column, and the main shaft is arranged vertically. Horizontal drilling machine: a drilling machine deep hole drilling machine in which the spindle is arranged horizontally and the headstock can be moved vertically.

Machining accuracy: Because the main shaft of the vertical deep hole drilling machine is arranged vertically and the center position is fixed, the accuracy is much better than that of the horizontal type.

Operation processing: The vertical clamping is convenient for batch processing. The horizontal clamping takes a certain amount of time from the tool to the workpiece, and the processing efficiency of the vertical type is much faster than that of the horizontal type.

Processing range: The current limit depth of vertical processing range is only 300mm, while the horizontal type can reach a depth of several meters. The horizontal type of the operating table is also not smaller than the vertical type, and it is suitable for processing various sizes of molds.

Easy to control: Both vertical and horizontal deep hole drills are currently controlled by numerical control, which realizes one-key processing and is simple and convenient to operate.
