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.

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.

Tungsten carbide double-edged boring tool, having adjusting the knife slide, capping and adjusting screws and other components. Look at the picture below. Arbor adopts material 40Cr to finish transfer material, arbor bulk processed two symmetrical chute as loaded knife slot, arbor shank for Morse taper shank on the 5th. arbor bore concentricity of the taper shank of 0.01mm, cylindrical blade adjustment slider and arbor bore with the gap of not more than 0.02mm, the next part really a cone angle of the cone is 40 °.

Segment materials of tungsten carbide double-edged boring tool uses 10mm × 12mm high speed steel material, while sharpening angle twice the length of the blade and the blade should be exactly the same, in order to ensure a higher degree of symmetry twice after put the knife holes.

Tungsten carbide ordinary single blade boring tool only has one main cutting edge, regardless of roughing or finishing can be applied, but lower productivity. Because tungsten carbide ordinary single blade boring tool has poor stiffness, so it’s easy to cause bending deformation, in order to reduce the radial deformation and vibration resistance when boring and boring bars, generally take a larger main angle, κ r = 75 ° ~ 90 ° .

Its hole is a common processing method and processing a wide range, can be rough, but also for finishing.

Tungsten carbide single-edged knife boring machine folder has the cutter arbor, limiting pin, cutting blades and other components. Arbor has a cross section of the center of the hole, the coolant is sprayed into the nose from the shank end of the hole through the head inclined, caudal and intermediate guide both ends of the center hole to beat strict requirements. Cutting blades requires high precision and small surface roughness values.

Tungsten carbide single-edged knife boring machine folder has two main angles, from the boring role as the main angle 15 °, the length of 1mm, played the role of reaming main angle of 3 °, the length of 2mm, back reaming part repair light blade, adjust the full length inverted taper (total length of radial deviation wiper size 0.002mm).

Tungsten carbide single-edged knife boring machine folder is only a single main cutting edge for cutting, simple structure, easy to manufacture, wide, with a boring tool holes of different diameters can be processed in a single direction.

Tungsten carbide boring tool is a tool, generally round handle, there are large work-pieces use square shank, the most common situations that bore machining, reaming, copying, etc. There are one or two cutting section devoted to the existing holes for roughing, semi-finishing or finishing tool. Tungsten carbide boring tool can be used on boring machines, lathes or milling machines.

Tungsten carbide boring tool is divided into two types, rough boring boring tool points, such as tungsten carbide fine boring tool.

Tungsten carbide boring tool from the structure can be divided into integral boring shank, shank and modular boring heads classes.

From the processing requirements, it can be divided into coarse tungsten carbide boring and fine tungsten carbide boring tool knife.

If you are a gold dealer and attend some trade fair or put your gold products in the showcase, what you want least is your gold products are stolen.

However, your shining gold products are always very attractive to the thieves. In order to reduce any possible great loss, you'd better to put a fake, but a very similar substitute for gold products.

Tungsten alloy golden rod or gold-plated tungsten rod are the best choice.

Tungsten carbide planer for planing, with a cutting tool parts. Tungsten carbide planer can be divided according to use longitudinal, transverse, grooving, cutting and shaping planer and so on. For planing, the tool having a cutting portion.

Tungsten carbide planer’s structure substantially is similar to turning, but the work was interrupted cutting planer, by the impact load. Therefore, in the same cutting section shank tools sectional size large than 1.25 to 1.5 times, and using large negative blade angle (-10 ° ~ -20 °), the cutting edges to improve the performance impact loads.
