Achieving High Productivity with Helical Cutting Inserts

UPAC separates pores into micropores (<2 nm), mesopores or mesopores (2 to 50 nm), macropores (> 50 nm) according to the pore size scale; according to the latest definition, the pores are subdivided into Micropores (<0.7 nm) and micropoles (0.7-2 nm), while wells below 100 nm are collectively referred to as nanopores. So how are the names of these hole materials come from?

MCM is short for Mobil Composition of Matter. Mainly by the Mobil Oil researchers, using ethyl silicate as a silicon source, synthesized by a micelle-based soft template method. MCM The Musketeers are MCM-41, MCM-48 and MCM-50. MCM-41 is a hexagonal mesoporous structure, the arrangement of a regular cylindrical mesopores made of one-dimensional pore structure. Mesopore diameter adjustable between 2-6.5 nm, large specific surface area. Compared to molecular sieves, there is no Bronsted acid sites in MCM-41. Due to its thin wall and low exchange rate of silicon units, Si-O bonds hydrolyze and re-crosslink in boiling water, resulting in structural damage. Therefore, Thermal stability is not good. The earliest papers on the synthesis of MCM-41 were published in the JACs in 1992, and the citations now have nearly 12,000 citations. (J. Am. Chem. Soc., 1992, 114 (27), pp 10834-10843.) MCM-48 has a three-dimensionally interconnected cell structure. MCM-50 is a lamellar structure and can only be referred to as “mesostructure” rather than “mesoporous” since the lamellar structure collapses upon removal of the surfactant-forming layer, and since there is no pore, this is not Deep down. 

Figure 1 MCM-41 synthesis mechanism diagram, the surfactant used is an anionic surfactant SBA series

SBA is short for Santa Barbara Amorphous. Among them, the big name is SBA-15. SBA-15 was first synthesized by Zhao Dongyuan, a teacher at Fudan University in 1998 after doing a post-graduate study at Santa Barbara, University of California, U.S.A. It was published in Science that year and has been quoted for more than 10,000 times (Science 23 Jan 1998: 279, 5350, 548-552.). SBA series of mesoporous silica materials are synthesized using a soft template method using a block type surfactant; its pore size is adjustable in the range of 5-30 nm. SBA-15 consists of a series of hexagonal parallel cylindrical channels with a few mesopores or pores arranged in random order with a cell wall thickness of 3-6 nm. Due to the thicker cell walls of SBA-15, the hydrothermal stability of the material is better than that of the MCM series. SBA-15 is a multi-dimensional porous material that contains both mesoporous materials. It can remove the surfactant embedded in the pore walls during the calcination process, resulting in a microporous structure.

Also belonging to the ordered mesoporous silica material, different from the SBA-15 (cubic p6mm) unidirectional pore structure, KIT-6 (cubic la3d) has interconnected cubic mesoporous structure. In the synthesis of KIT-6, a mixture of triblock surfactant (EO20PO70EO20) and butanol was used as a structure-directing agent. KIT-6 pore size adjustable in 4-12 nm, the specific surface area of 960-2200 m2 g-1. (Chem. Commun., 2003, 2136-2137)

Figure 6 (left) Structure diagram of SBA-15 p6mm and KIT-6 la3d, (right) TEM image of KIT-6 CMK series

The common method for synthesizing mesoporous carbon is the hard template method. Mesoporous molecular sieves such as MCM-48 and SBA-15 are used as template to select the appropriate precursors, carbonize the precursors under the catalysis of acid and deposit on the pores of mesoporous materials Road, and then dissolved with NaOH or HF mesoporous SiO2, to get mesoporous carbon. In 1999, Ryoo succeeded in replicating other mesoporous materials using mesoporous materials as hard templates. This series of materials named CMK. Also did not find the official naming, but most likely Carbon Molecular Sieves and Korea combined naming. He has successively Indexable Carbide Inserts produced CMK-1, CMK-2, CMK-3, CMK-8 and CMK-9 mesoporous carbon molecular sieve materials using MCM-48, SBA-1, SBA-15 and KIT-6 as templates. (J. Phys. Chem. B, 103, 37, 1999.) CMK-3 is a two-dimensional hexagonal structure with a narrow pore size distribution, high specific surface area (1000-2000 m2 / g), large pore volume 1.35 cm3 / g) and strong acid and alkali resistance, is a good catalyst carrier.

FDU series is short for Fudan University and is the work done by Zhao Dongyuan teacher after returning to Fudan University. FDU is a series of phenolic resins synthesized by soft-template method. The ordered mesoporous carbon materials can be synthesized by high-temperature carbonization and consist of spherical pores. The same is the VNMG Insert use of surfactant as a structure-directing agent, the use of phenolic resin precursors as raw materials, by solvent evaporation self-assembly method to get the orderly structure. (Angew. Chem. Int. Ed. 2005, 44, 7053-7045)

Starbon is the name of the mesoporous carbon material. Because the original Starbon was synthesized by researchers at the University of York by the sol-gel method of Starch and then carbonized. Therefore, its name is Starbon, and registered the brand name “Starbon”. Starbon mesopore volume of 2.0 cm3 / g, the specific surface area of 500 m2 / g, can be used as a catalyst carrier, gas adsorption or water purification agent. Now Starbon raw materials can be extended to pectin and alginic acid.

ZSM is an abbreviation for Zeolite Socony Mobil, and ZSM-5 is a trade name, which is the fifth Zeolite found by Socony Mobil Corporation. Synthetized in 1975, Nature reported its structure in 1978. ZSM-5 is an orthorhombic system. It is a kind of zeolite molecular sieve with three-dimensional cross-channels with high silicon and five-membered rings. It is oleophilic and hydrophobic, has high thermal and hydrothermal stability, and most of the pores have a diameter of about 0.55 nm Hole Zeolite.

Figure 10 TPABr synthesized ZSM-5 AlPO series

AlPO is the abbreviation of acid-free microporous aluminophosphate molecular sieve, which is the “second-generation molecular sieve” developed by the UOP Company of the United States since the 1980s. These molecular sieve frameworks are composed of an equal amount of AlO4- and PO4- tetrahedra and are electrically neutral and show weaker acid-catalyzing properties. With the introduction of heteroatoms, the original charge balance of the AlPO zeolite framework can be broken down , So that its acidity, adsorption performance and catalytic activity were significantly improved. The framework structure of AlPO4-5 belongs to the hexagonal system, with a typical 12-membered ring main channel with a pore size of 0.76 nm, which is comparable to that of aromatics.

Inspection System Helps Company Meet Short Lead Times

Powder metallurgy is the technology of making metal powder or using metal powder (or mixture of metal powder and non-metal powder) as raw material, through forming, sintering, and manufacturing metal materials and various types of products. There are some similarities between powder metallurgy and ceramic production, which belong to powder sintering VBMT Insert technology. Therefore, The metallurgy technology can also be used in the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solve the problem of new materials and plays an important role in the development of new materials.

Contents hide 1Application fields of powder metallurgy 2Advantages of powder metallurgy process 3Disadvantages of powder metallurgy process 4Natures of the powder is vital 5Common powder metallurgy forming process 5.1Grinding process 5.2Planing 5.3Metal deposition 5.4Turning 5.5Drawing processingApplication fields of powder metallurgy

First of all, powder metallurgy technology can minimize the segregation of alloy components and eliminate the coarse and uneven casting structure. It plays an important role in the preparation of high performance rare earth permanent magnetic materials, rare earth hydrogen storage materials, rare earth luminescent materials, rare earth catalysts, high temperature superconductors and so on.

Secondly, a series of high-performance materials such as amorphous, microcrystalline, quasicrystal, nanocrystalline and supersaturated solid solution are prepared. These high-precision materials have excellent electrical, magnetic, optical and mechanical properties.

Then using powder metallurgy technology can easily realize various types of composite, give full play to the characteristics of each group of source materials, which can be said to be a low-cost production of high-performance metal matrix and ceramic composite technology.

In addition, powder metallurgy technology can realize near net shape forming and automatic mass production, and also can effectively save production resources and reduce energy consumption.

Using powder metallurgy technology can make full use of ore, tailings, steel-making sludge, steel mill scale, recovery of waste metal as raw materials. It is a new technology that can effectively carry out material regeneration and comprehensive utilization.

Advantages of powder metallurgy process

1. It can process special materials. Materials powder metallurgy can be used to manufacture refractory metals, compounds, false alloys and porous materials.

2. Save metal and reduce cost. Because powder metallurgy can be pressed into the final size of the compact, no need to use machining. The loss of metal produced by this method is only 1-5%, while that of general processing is 80%.

3. Prepare high-purity materials. The powder metallurgy process does not melt the material in the material production process, and it will not mix with the impurities brought by other substances. The sintering is carried out in the vacuum and reduction atmosphere, and it is not afraid of oxidation or any pollution of the material. Therefore, the purity of the product is relatively high.

4. Correctness of material distribution. Powder metallurgy can ensure the correctness and uniformity of the material composition in the proportion.

5. Mass production reduces cost. Powder metallurgy is suitable for the production of products with a large number of uniform shapes, such as gears and other products with high cost, which can greatly reduce production costs.

Disadvantages of powder metallurgy process

1. The strength and toughness of P / M products are poor. Because the internal pores of the pressed billets can not be eliminated completely, the strength and toughness of P / M products are worse than those of castings and forgings with corresponding components.

2. Powder metallurgy cannot be made into large products. Because the fluidity of metal powder is worse than that of liquid metal, its shape and size will be limited to a certain extent, and its weight will not exceed 10 kg.

3. The cost of die is high. Because the cost of die manufacturing is too high, it is only suitable for mass production.

Natures of the powder is vital

Powder is a general term for all properties, including the geometric properties (particle size and shape), chemical properties, mechanical properties and physical properties of powder. These properties can’t be obtained by traditional casting method. To a large extent, powder properties often determine the properties of P / M products.

Granularity. It is shrinkage during sintering and the final performance of the product, which can affect the processing and forming of the powder. Some properties are almost directly related to particle size. For example, the filtration accuracy of filter material can be obtained empirically by dividing the average particle size of the original particle by 10.

The particle shape of the powder. It depends on the pulverizing method, such as the powder produced by electrolysis, the particles are dendrite like; the iron powder produced by reduction method is sponge like. In addition, some powders are egg, disk, needle, onion, etc. The shape of powder particles will affect the fluidity and bulk density of powder. Because of the mechanical meshing between particles, the strength of irregular powder is also large, especially for dendrite powder. But for porous materials, spherical powder is the best.

Mechanical properties the mechanical properties of powder are the technological properties of powder. It is an important technological parameter in powder metallurgy forming process. The loose density of powder is the basis for weighing by volume method during pressing; the fluidity of powder determines the filling speed of powder to the die and the production capacity of the press; the compressibility of powder determines the difficulty of pressing process and the pressure applied; and the formability of powder determines the strength of the billet.

The chemical properties mainly depend on the chemical purity of raw materials and the method of pulverizing. The higher oxygen content will reduce the pressing performance, the strength of compacts and the mechanical properties of sintered products, so there are certain specifications in most of the technical conditions of PM.

Powder metallurgy has unique chemical composition, mechanical and physical properties which can not be obtained by traditional casting methods. Porous, semi dense or fully dense materials and products, such as oil bearing, gear, cam, guide rod, cutter, etc., can be directly made by using powder metallurgy technology. It is a kind of powder metallurgy product that needs little or no cutting.

Common powder metallurgy forming processGrinding process

Metal deposition

It is similar to the “milking oil” type of molten deposition, but the metal powder is ejected. In addition to spraying metal powder materials, the nozzle also provides high-power laser and inert gas protection. In this way, it will not be limited by the size of the metal powder box, and can directly produce larger parts, and it is also very suitable for the repair of local damaged precision parts.

Turning

Turning is one of mechanical machining methods. Spinning work piece gets processed by turning bits on working platform of lathe.It efficiently machines work piece consisting of spindle, plate, casing, and that with rotary surface. It’s safe to say turning is the most widely applied lathe machining in machine manufacturing. Turning is a method of cutting workpiece by using workpiece rotation relative to cutter on lathe. The cutting energy of turning is mainly provided by workpiece rather than tool. Turning is suitable for machining the rotating surface. Most of the workpieces with the rotating surface can be machined by turning methods, such as the inner and outer cylindrical surface, the inner and outer conical surface, TCMT Insert the end face, the groove, the thread and the rotating forming surface, etc. the tools used are mainly turning tools.

Drawing processing

Drawing process is a kind of plastic processing method which pulls the metal blank out of the die hole smaller than the section of the blank by the help of external force to obtain the corresponding shape and size of the product. Because drawing is usually carried out in cold state, this process is also called cold drawing or cold drawing.”

The passivation treatment of tools can help improve the rigidity of tools and avoid premature loss of cutting performance of tools.

2. Maintain the smoothness of the workpiece

Burrs on the cutting edge of the tool will cause tool wear, and the surface of the machined workpiece will become rough. After passivation treatment, the cutting edge of the tool will become very smooth, the phenomenon of edge collapse will be reduced accordingly, and the surface finish of the workpiece will also be improved.

3. Convenient groove chip removal

Polishing the tool groove can improve the surface quality and chip removal performance. The smoother the groove surface, the better chip removal will be, and more consistent cutting can be achieved.

After passivation and polishing, the tools of CNC machine tools will leave many small holes on the surface. These holes can absorb more cutting fluid during machining, which will greatly reduce the heat generated during cutting and greatly improve the cutting speed.

This is the earliest and most widely used passivation technology.

Nylon brush?edge radius?method

it is a common method to coat the abrasive medium of fine particles on the brush wheel or brush disc of nylon material, and re move the cutter through the high-speed rotation of the brush.

Sand blasting method

it is divided into dry sand blasting and wet sand blasting. It is also a common method of edge radius processing. Compared with nylon brush method, this process accomplish?a higher consistency of edges.

Stirring method of edge radius processing

This method is to put the whole tool into the abrasive bucket before treatment, and position the depth of the tool through the laser sensor to ensure the quality of treatment. The blade consistency of this process is also higher than that of nylon brush method.

Electrochemical mechanical edge radius processing

This is a composite process that combines electrochemical machining and mechanical grinding. First, electrolytic deburring, and then mechanical grinding to remove oxide film.

Laser method: it is a passivation technology developed on the basis of laser cladding technology. It can produce high heat on the blade surface by laser, melt some materials, and achieve the effect of passivating the blade.

Vibration edge radius processing method

 the main processing device includes a vibration table and a worktable. The blade is placed in a container that is connected with the vibration body. The container is filled with abrasive particles. The abrasive particles and the blade repeatedly collide to remove trace materials on the cutting edge through collision to achieve edge passivation.

Magnetic abrasive method

This is a edge radius processing that applies a magnetic field in the direction perpendicular to the axis of the cylindrical surface of the workpiece, and adds magnetic abrasive between the magnetic field S and N poles. The magnetic abrasive will be adsorbed on the magnetic pole and the workpiece surface, and will be arranged into a flexible “abrasive brush” along the direction of the magnetic line of force. The cutter rotates and Carbide Milling Inserts vibrates axially at the same time to remove the metal and burrs on the workpiece surface.

Micro abrasive water jet technology: a new and environment-friendly processing technology, which forms a liquid-solid high-energy jet through the control of the pressurizer and nozzle diameter, and realizes passivation treatment by high-speed and repeated collision on the workpiece.

The Benefits of Using Carbide Cutting Tools

BIG KAISER’s EWN boring head was recently featured in an article on Modern Machine Shop magazine. The article highlights how Ansonia Manufacturing, the only machine shop in the town of Sonoma, California, discovered our EWN2-32ExER32 boring head and how this tool helped them Tungsten Carbide Inserts complete a tricky hardware component job for a “live” glass art sculpture.

At the beginning of the article, owners Andrew and Jamie Storck share details about the complexity of the sculpture, specifically one of the seven parts which proved particularly challenging. Called a “lollipop,” this 7-inch-long, 304-stainless-steel component featured a 7/16-inch-diameter shaft and a 7/8-inch sphere on one end with a through-hole and a smaller tapped cross-hole to lock in the swivel component that installs in the through-hole.

The Storcks knew that a boring head would be needed to machine the sphere’s through-hole. As stated in the article, “at IMTS the Storcks discovered that the EWN2-32ExER32 from BIG KAISER attached directly to theexternal threads on LB 3000’s live-tooling station without the need for a collet or collet nut. As a result, the boring head’s insert was closer to the face of the turret station for better rigidity. They had found the answer to their problem.”

“After we installed the boring head and started running parts, we never had to adjust the head’s diameter or change the insert for the entire 1,200-part run,” Ms. Storck says. “That certainly speaks to the quality Threading Inserts of this boring head.”

BIG KAISER’s EWN2-32ExER32 adapts to live tooling stations by removing the standard ER32 clamping nut and screwing the boring head directly onto the ER32 station. This eliminates the need for straight shank adapters and substantially reduces unnecessary tool projection from the turret.

How To Choose The Grade Of Cemented Carbide For Mining Tools

The correct choice of cemented carbide mining tool grades is one of the most important factors to ensure the effective use of cemented carbide.

When choosing cemented carbide grades, the toughness of the alloy should be emphasized for extremely hard Threading Inserts rocks and heavy-duty rock drills with large impact energy, and alloy grades with higher cobalt content should be selected; for hard, brittle, and corrosive rocks, emphasis should be placed For the wear resistance of the alloy, select alloy grades with slightly lower cobalt content; for medium-hard and below-medium-hard rocks, use alloy grades with lower cobalt content and higher hardness; for coal mining under heavy loads Cemented carbide for machine picks is mainly used to reduce the content of cobalt and increase the grain size, thereby greatly improving the bending strength and impact toughness of the alloy; for cylindrical teeth, cross, and three-blade drill bits, use hardened with lower cobalt content. Quality alloy. At the same time, the following points should be noted:

1. The physical and mechanical properties of the rock formation, such as hardness, friction, etc. and its shape characteristics. The generally adopted principle is: the APMT Insert harder the rock to be cut, the better the toughness of the selected alloy sheet, but not too soft. Note that the wear resistance should not be too low, because too soft will increase the consumption of the alloy and reduce the drilling efficiency. For rock formations with many cracks, regardless of the hardness and the type of rock drill used, the cross-shaped bit should be used .

2. Model of rock drill, such as light, heavy, etc.;

3. Rock crushing method (cutting, shearing, crushing, crushing, etc.);

4. Equipment capacity (wind pressure level)
