Tungsten Carbide Staggered Edge End Mill

Tungsten carbide staggered edge end mill is a kind of new special cutter for fiber composite materials, its cutting edge is divided into upper and lower parts, the workpiece material should be on the middle area under the producing process. Due to the use of a proximal portion of the cutting edge blade right-handed, left-handed blade near the handle of the staggered design, the lower end of the right-handed cutting edge end mill for milling under the surface, under the surface by the upward cutting force; standing upper cutter L on the cutting edge for milling the surface, on the surface by the downward cutting force. Thus, the material, the lower surface of the fibrous layer are completely cut off easily, effectively preventing the upper and lower surfaces of the workpiece tear, burrs and other processing defects.

Spiral staggered around edge carbide end mill is mainly used for paper trimming and milling aramid honeycomb sandwich composites. Since the cutting edge of the tool is symmetrical about a staggered spiral, and helical cutting edge around the junction is always held in the neutral position of the paper and the aramid honeycomb sandwich structure, and therefore, in the trimming process, two surfaces of the sandwich structure cutting force is always toward the center of the sandwich structure, thus avoiding crack, layer or spinning phenomenon.

Tungsten Carbide Anvils

Code key for the description of sintered tungsten carbide anvils

DC636: DC means the name of sintered products, 6 means category of sintered products, 36 means dimensions of the working facets of sintered products.

a. The part is 2 Chinese phonetic alphabets indicating the name of sintered products. For example, DC indicates anvils and DG indicate pressure cylinders.

b. The second part is one numeral indicating the category of sintered products. For example, 6-facet anvils are indicated by 6 and 2-facet anvils and pressure cylinders are indicated by 2.

c. The third part with 2 numerals indicates the dimensions of the working facets of the anvils or the dimensions of the cavity of the pressure cylinders with only integers.

Carbide anvil’s type consist by the model of the finished product, code-named top hammer, the top diameter, the size of the top surface, edge length, nominal angle, height, outer cone of the outer cone of the code serial number, a large ramp angle, large composed of twelve part serial codes bevel angle, the shape of the top surface, the top surface shape of the code.

Tungsten Carbide Pressure Cylinders Aadvantages
1. Tungsten carbide cylinder with stable quality, good density, high overall performance.
2. Pressure cylinder is designed to follow the basic principles of mechanics, is a brittle material, has a high compressive strength, shear force is weak.
3. The general grade of pressure cylinders is YG8 & YL30.3, is the diameter is bigger than 90mm, it is use YL30.3.

Tungsten Carbide Jig

Tungsten carbide jig means drilling on the workpiece or reaming with machine fixture.

The structural characteristics of the jig is carbide addition to positioning of the workpiece, the clamping device, there is the position in accordance with the distribution of processed holes provided drill sleeve and drilling template to determine the position of the tool, and to prevent the machining tool tilt process, thus ensuring the positional accuracy of the hole to be machined.

Tungsten Carbide Jig Application

Ensure the position of the jig to improve drilling efficiency, reduce workers' technical requirements.

Uses of Tungsten Carbide Jig

1, flange 2, the motor plate 3, base, 4 hydraulic valve block 5, cover 6, nuts 7, washers 8, shafts, etc.

Tungsten Carbide Jig Processing Methods

Old: Finishing well drilling template, and then drill into the casing pressure.

New: The first drill sleeve positioned within fortunately certain environment, then pouring the filler cap, suitable for use hydraulic valve block using a jig flange class. 

Tungsten Carbide Kits

Tungsten carbide kits with high hardness, wear resistance, toughness, heat resistance, corrosion resistance, long life and other advantages, the average life is 30 times more than ordinary kits, but also at a higher temperature By continuing to work and increase efficiency.

Tungsten carbide kits can be divided into fixed kits, interchangeable kits, quick-change kits and slant-hole kits and other four types, is to guide the drilling or reaming tools used in the machine on the workpiece fixture, to determine the tool position and the tool during processing to prevent vibration, inclination, thus ensuring the positional accuracy of the hole to be machined.

Tungsten carbide fixed kits mainly used for small batches. Under production conditions with simple step drill hole. Fixed kits is mounted directly in the corresponding holes drilled in the template, so after a fixed kits wear generally can not be replaced.

Shoulder primarily for drilling template is thin, necessary for holding the drill guide sleeve length. With the shoulder, you can prevent the cutting and coolant falls on drilling template kits hole. The lower end of fixed drilling sleeve should extend beyond drilling template, in order to prevent the ribbon cutting and increased involvement of the kits kits wear.

Tungsten Carbide Products

Tungsten carbide is a material used for a number of industrial applications and it is characterised by its high strength, toughness and hardness. Its name derives from the Swedish for tung (heavy) and sten (stone) and it is mainly used in the form of cemented tungsten carbides. Cemented carbides (also known as hardmetals) are made by 'cementing' grains of tungsten carbide into a binder matrix of cobalt or/and nickel.

Tungsten carbide as a material can vary in carbide grain size (0.2 – 50 microns) and by binder contents (up to 30%), as well as by the addition of other carbides. By varying the grain size of the tungsten carbide and the binder content in the matrix, engineers have access to a class of materials whose properties can be tailored to a variety of engineering applications. This includes high-tech tools, wear parts and tools for the construction, mining and oil and gas sector.

Tungsten carbide products typically have a high resistance to wear and can be used at high temperatures, allowing tungsten carbide's combined hardness and toughness to significantly outperform its steel product equivalents.

Tungsten Carbide Polished Ball

Tungsten carbide polished ball is polished from blank ball, which are able to reach the surface of G25, with high density, high wear resistance and small friction，are widely used in high-tech equipment and petroleum, ball seal and other industries.

Tungsten carbide polished ball with high density, high strength, high wear resistance, high acuracy and could bear high corrosion-resistant and high temperature.

Tungsten carbide add with Co is the best material for tungsten carbide polished ball, which could manufacture the most extremely precise ball. Are widely unsed in precision bearings, instruments, meters, pen, spraying machines, water pumps, mechanical parts, sealing valves, brake pump, squeeze-hole punch, oil, hydrochloric acid laboratory, hardness measuring instrument, gear, weight, decoration, finishing and other high-end industry. Tungsten carbide ball include blank balls, finished balls, punching balls, bearing balls, valve balls, non-magnetic balls, monel balls, hole balls, measuring balls, scratch chromospheres and pen balls.
