Tungsten carbide deep hole boring tool also called deep hole boring head, divided into split type and combined type. Tungsten carbide deep hole boring tool head is one kind of deep hole boring tool cutter, involving: deep hole drills, deep rolling head, deep hole boring head. First drill hole drilling and rolling, finally bore (it should be rough boring, fine boring, rolled, and finally rolling, surface finish can be achieved after rolling 0.4μm).

The new tungsten carbide deep hole boring tool head is a three-blade BTA deep hole boring head, upper body fixed set with two boring bars and three cutting edges, bars and cutting edge at the same cylindrical surface of the outer edge. Tungsten carbide deep hole boring tool head is provided with two out crumbs mouth, mouth cavity under the debris semicircle extending forward 2-5mm. As a result of the chip work, the oil is fed from the boring bar outside, after the bars and cutting edge, fold back carrying the chips from the boring bar cavity discharge backwards to achieve a boring head and guide the cutting edge of the full cooling lubrication, on this basis, further freely super-hard cutting tool materials using cutting edge and the guide bar, in order to achieve high speed and precision of tungsten carbide deep hole boring tool.

The tungsten carbide double-edged boring tool’s both side symmetrically at the center of rotation of the blade, and also participate in cutting feed resistance generated symmetrical balance, radial component which cancel each other out, no longer affected by the spindle and swing around. It completely eliminates the single-blade knife’s boring bar unidirectional force, resulting in the spindle shaking and, therefore, apply to be mounted on a vertical radial drilling boring. The tungsten carbide double-edged boring tool’s head is easy to find the blade , and the radial dimension of the head can be fine tuned to be gradually enlarged, especially for those who simply boring circle, and the position accuracy is not too high bore.

As the head of the expansion volume can be adjusted, and thus a large aperture range of machining can be boring Ø80 a 150mm hole can also be boring certain size blind hole.

As for tungsten carbide trimming boring tool, there is no difficulty in the manufacturing process. The key place is the holder and seat adjustment nut threaded shank and with precision machining, thread here that is used to adjust the tool size for both fixed Arbor. Wire nut hole is processed with special taps, arbor hole with threaded with silk mill. Generally the thread pitch 0.5mm, engraved lines and values ​​are shown with micrometer precision same principle.

Tungsten carbide trimming boring tool must be installed into its matching boring rod used on boring machines, machining centers, special machine tools. Tungsten carbide trimming boring tool in fine-tuning rod installed in two ways: one is mounted at right angles, Tungsten carbide trimming boring tool’s axis and the axis of the boring bar 90 °, generally used for through-hole machining. The other is mounted at an angle, trimming boring tool axis and the axis of the boring bar 53 ° 8 ', generally used for blind hole machining. Both installation boring tool 75 ° and 90 °, there are two main declination.

The key to using the tungsten carbide double-edged boring tool is to ensure that the two edges of the boring bar symmetry center, from sharpening knives should pay attention to the loading point, otherwise easily occur when a single-edged knife to eat boring, tungsten carbide double-edged boring bar caused by unidirectional force, destruction of machine tool’s stability and affect accuracy.

From machine to ensure stability considerations, tungsten carbide double-edged boring tool should only be taken when the boring low-speed small amount of feed. Its speed and feed rate was 25r/min and 0.04mm / r, eating knife depth is about 0.5mm.
