Tungsten Carbide Ordinary Single Blade Boring Tool

Details: Category: Tungsten Information; Published on Tuesday, 22 July 2014 14:52

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

Details: Category: Tungsten Information; Published on Tuesday, 22 July 2014 14:51

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 Fine Boring Tool Introduction

Details: Category: Tungsten Information; Published on Tuesday, 22 July 2014 14:42

Tungsten carbide fine boring tool is to ensure the accuracy of the aperture to guarantee that the location, roughness, roundness, etc..

In the processing centers, there are generally tungsten carbide fine boring tools with fine-tuning, there is a diametrical direction 0.01MM adjustment, as well as adjust the volume 0.001MM .

Tungsten Carbide Boring Tool Introduction

Details: Category: Tungsten Information; Published on Tuesday, 22 July 2014 14:40

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.

Tungsten Alloy Rod for Gold-plated Substitution 2

Details: Category: Tungsten Information; Published on Tuesday, 22 July 2014 09:28

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

Details: Category: Tungsten Information; Published on Monday, 21 July 2014 18:51

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.

Tungsten Carbide Thin-shank-machine-tap

Details: Category: Tungsten Information; Published on Monday, 21 July 2014 18:50

Tungsten carbide thin-shank-machine-tap is used for fine machining deep hole common thread (GB192 ~ 193, GB196 ~ 197) of the internal thread.

Tungsten carbide thin-shank-machine-tap’s features and precision: fine shank machine taps rotate clockwise direction, the precision is divided into three tolerance levels. That is: H1, H2, H3.

H1 level: suitable for processing thread 4H, 5H's;

H2 grade: suitable for processing 5G, the internal thread 6H;

H3 level: suitable for processing 6G, internal thread 7H, 7G's.

Tungsten Carbide 60-tapered-pipe-thread’s Feature

Details: Category: Tungsten Information; Published on Monday, 21 July 2014 18:46

Tungsten carbide 60-cylindrical-pipe-thread relies entirely on their own to form a seal between the threads without any sealing medium. Dry seal pipe thread stipulates a more stringent tolerances, precision metal thread , only on special occasions.

Tungsten carbide 60-cylindrical-pipe-thread has high strength and good sealing, the use of threads on the brittle material having a thin cross-section can reduce breakage. Tungsten carbide 60-cylindrical-pipe-thread between internal and external thread with no gaps, isan interference fit. There is transition cooperation with Tungsten carbide 60-cylindrical-pipe-thread. It is mainly used for high temperature and pressure on the sealing demanding places.

Tungsten Carbide 60-tapered-pipe-thread Introduction

Details: Category: Tungsten Information; Published on Monday, 21 July 2014 18:44

Tungsten carbide 60-cylindrical-pipe-thread, is also known as NPTF. US-made dry seal tapered pipe thread, National (American) Pipe Thread abbreviation belonging to the American standard 60-degree taper pipe thread for the North American region. Its tooth type angle of 60 degrees, cone degrees 1:16 taper limit deviation of -0.005 ~ +0.005 mm / mm NPTF thread of one and two two levels.

For the level, to test the height level of the thread. When a standard test can be omitted NPTF male thread, to ring simultaneously with the L1 and L2 ring; within the detection tungsten carbide 60-cylindrical-pipe-thread, we should use with the L1 plug and L3 plug at the same time.
