AN ALL-ROUND PERFORMER

Calcium carbide and increase the service life.
Calcium carbide is a composite consisting of relatively hard and soft packaging materials. These materials are too difficult, high wear resistance, high toughness hot. Used in various areas in need of tools or wear resistant components, such as the machining of hard materials; carbide improves the quality of tools and components, giving her the longest serving life and ensure safe operation.
Carbide recipe for success
We have made of tungsten carbides, super strong and ductile cobalt. The fused material in powder form. The quantity of cobalt used tungsten carbide grain size affects the properties of the abrasive performance, such as hardness, bending strength and fracture toughness. Ceratizit produces over 130 grades of carbide, each with its own unique material composition we have the perfect solution for every application in industry.
Production of tungsten carbide blanks
To make the completion of the powder mixture, carbide blank, you first need to go in the template resulted in a green compact can thus be formed. Once the is sintered at a temperature of between 1300 and 1500 degrees C and pressure up to 100 bar, the green compact is turned into a dense homogeneous carbide.
All of the production of carbide series
Our teachers the whole production chain, from the production of powder molding and sintering on the finishing grinding, polishing, corrosion, surface treatment: We blank and cover it with wear resistant coating for innovative products. This gives the desired properties for industrial applications.

Geometry and tools

A variety of grooves, slots,In the pockets in the work-piece may result from a variety of tool bits. A common tool bit types: square end cutters, ball end cutters, cutters T-slot; shell end mills, box cutters mill can be square slots, pockets, and edges; ball end mill cutters or fillet radii of the openings. T-slot milling cutters, exactly, to form openings T. Shell end cutters are used for large flat surfaces and the corner cuts. There are variations of these types of tool as well.
There are four critical angles of each end of the cutting tool, and cutting edge angle, relief angle, radial and axial relief angle and radial rake angle.
Depending on the material is milled, and the task to be accomplished, can use different types of tools and engineering. For example, when the grinding material such as aluminium, polished flutes may be helpful to use a very deep, very sharp cutting edge, high rake angles. When the machining difficult materials such as stainless steel, however, the shallow flutes and the square opposite the cutting edge of optimum material removal and tool life.
A wide range of materials used in the production of cutting tools. Tungsten is the most commonly used because it is good for the production of high grinding. High speed steel tool usually used when special shape is required and not usually used for high production. Ceramic inserts are typically used in high speed machining with high production. The diamond used usually in the products that require tight tolerances usually consists of a high surface qualities (metal or non-metallic materials). I in early nineties, and the use of coatings to reduce wear of friction (among other things), became more common.

  • Tin (yellowish coating, which has fell out of widespread use.
    TiCN (popular, bluish gray paint
    TiAlN figs (extremely popular, dark purple paint)
    Tialcrn alticrn alcrtin (PVD paint).
    PCD veins. Although not coated end mills manufactured with some of the ‘soul’ polycrystaline diamonds. The vein is formed in the environment of high temperature and high pressure. The blank shape and materials out of the ground along the vein to form the cutting edge. Though the instruments can be very costly, can be can last many times longer than other tools.
    Advances in end mill. The painting, however, with coatings such as amorphous diamond coating of nanocomposite PVD start to believe in the upscale shops. 2004).
    End mills are usually on the CNC (computer numerical control) machine tool cutting and grinding machines, under the pressure of the lubricant such as water, water soluble oil, volatile oil, high. Inside the grinding machine with grinding wheel mounted on the spindle (and in some cases, depending on what multiple spindles). The material is ground, these wheels are made from synthetic diamond (when grinding tungsten carbide, cubic boron nitride (when grinding cobalt steel), and other materials (on the D grinding, for example, ceramics), brass (sometimes in a bond).

Basic requirements for cutting tools

A material is the key factor that determines the performance of the cutting tools, and have a significant impact on the quality and efficiency of machining, machining tool and machining cost. Durability. The use of carbon tool steel as the cutting tool material, cutting speed and is a 10M / min; the early twentieth century material of high-speed steel cutting tool, cutting speed up to tens of meters per minute; in thirties, the alloy steel cutting speed increased to more than 100 meters per minute to several hundreds M N, m; when the former ceramic tool and super hard material and tool, so as to increase the cutting speed over one thousand meters per minute, during the development of processing materials has greatly promoted the development of cutting tool materials.
Tool material with good performance is a prerequisite for ensuring the efficient operation of cutting tools, cutting tools, cutting work. Under the strong friction, high pressure and high the temperature should be the following basic requirements.
1) high hardness and high wear resistance of the tool material should be higher than the hardness of the material that is the basic requirement of cutting tools, metal cutting machine. The material, the hardness of the material above the tool 60HRC. Harder material is a better corrosion resistance, but due to the complicated cutting condition, wear resistance of the material depends. The chemical composition and the stability of the structure of a metal.
2) sufficient strength and impact toughness and impact resistance force cutting force, but not broken knife edge breakage performance must be expressed as usually by bending strength. The toughness effect refers to a physical device in intermittent cutting and impact under working conditions to ensure that the ability to break edge, a high hardness, low impact toughness more brittle material. The hardness and toughness of contradiction, and also the key to overcome material cutting tools.
3) high temperature resistance, heat resistance, hardness, also known as red, is the main key performance index. It reflects the hardness, wear resistance strength, oxidation resistance, adhesion resistance and tool materials at high temperatures.
4) good manufacturability and economy. In order to facilitate the manufacture of tool material should have good manufacturability like forging, heat treatment, grinding performance. Economic considerations should be taken into consideration in the selection and manufacturing industries. At present, the cost of materials superhard coated cutting tools are more expensive, but the service life a very long time. In the batch and mass production, the cost of each part is reduced. Therefore, comprehensive study must be selected.

Drill material

The drill bit used in printed circuit boards are usually made of solid concrete, because the epoxy glass cloth copper clad panel cutouts. The very fast wear the so-called binder cobalt powder, tungsten carbide powder, matrix, by compression and sintering. Usually contains tungsten carbide cobalt containing 94%, 6 percent because of the very high hardness wear resistance, has a certain strength, and suitable for high speed cutting. But the poor rigidity. U too, in order to improve the performance of some hard substrate of cemented carbide, titanium carbide alloy steel with chemical vapor deposition layer of 5 to 7 microns. TiC (titanium nitride (TIN), which has a higher hardness. Other uses ion implantation technology titanium, carbon and nitrogen injection into the substrate. A certain depth, which not only improves the stiffness and strength even when they move regrinding drilling drill bit. Also, the diamond film is formed on the top of the means. The material, which improves the e I greatly the hardness and wear resistance. The stiffness and strength of cemented carbide drill is not only related to the ratio of tungsten carbide cobalt, but also boosted powdered particles. Cemented carbide with an average size of 1 microns. This kind of rig has high hardness, but also improves the compression and bending strength. In order to save the cost of many alloy steel welding handle of the original structure, bit by bit, drilling deal now with the background of stainless steel, but the price is reduced to a degree copy T because of the use of different materials and its dynamic concentric basement full of hard alloy bit, particularly small diameter.

Milling method

There are two ways to feed the workpiece relative to the direction of workpiece and the direction of rotation of the cutter.
The first is grinding out. The direction of rotation of the cutter is the same as that of the cutter. At the beginning of the cut burr of workpiece and cutter cuts the final chip.
Second is the reverse feed grinding and cutting cutter rotation in the opposite direction, the milling cutter in the workpiece must be slip at the beginning before cutting, the cutting thickness February, to the end of the maximum cutting thickness.
The cutting force has three factories in different directions on the edge of the end or face mills. In face milling cutter is just out of the job, should be given more attention to the direction of the cutting force of workpiece in grinding and cutting out the force pressure around the table. While the opposite forces cut the workpiece away from the table.
Progressive grinding effect is better, because the cut usually preferred grinding screw gap. Only when the machine has problem, has the problem that the grinding can be reverse grinding is solved.
Ideally, the diameter of the milling cutter is greater than the width of the workpiece, it should always be the focus of milling cutter, a short distance away from the center line. The job. Burr is easily produced when the tool is placed against the center pieces. Continue to enter and exit the cutting edges of the cutting force in the radial direction. It will change, and may damage the spindle and the blade vibration, and the surface can be very distracting and grinding ore is slightly off the center of the cutting force direction will not change. Will now – cutter Get preload. We can compare the grinding medium to drive the car in the middle of the road.
Every time he enters the cutter cutting edge, the cutting edge under the impact load, the load depends on the cross section of the chip, workpiece material, cutting. Is an important direction to cut between the cutting edges cutting when cutting the workpiece properly.
When the cutting axis is entirely outside the width of the workpiece, and the impact force in the remotest corner of the blade, and a cutting means. The initial load by the most sensitive part of the tool. It leaves the workpiece milling cutter on a knife edge, and a cutting blade from beginning to end, and shredder the force acts on the effect of the farthest point until it is empty. When the centre line of milling cutter is just on the edge of the workpiece when the slice thickness reaches a maximum. The blade. I cut the effects of load reaches the maximum when the pieces are cut. When the cutting axis is displayed in the job, the initial impact load is borne on the cutting edge of the most sensitive point away from the cutting edge, and when it dropped, the code is relatively stable.
A newer method of each blade moves away from a workpiece is important as when they come out of the cutting knife, the removal of residual materials may reduce when the blades. Chips of the workpiece along a blade inclined surface will produce instantaneous tensile force on the job and often produce burr. This tensile force threatens the safety edge hazardous conditions.
