how to choose the correct workpiece material being cut saw blade
1, aluminum blade:
A generally used alloy saw blade, alloy saw blade itself when it must be done inlaid alloy head; if no inlay alloy is not a blade, while just steel, not a blade; cutting aluminum partakers fine cut or rough cut (usually cut the radiator is relatively high, as is sanding paper generally used to cut aluminum is not very high.)
B cut aluminum alloy blades toothed gear selection Ladder (also known as the high and low gear, ladder flat teeth)
D. Aluminum is also useful for some guests to high speed hacksaw to cut. (Mainly to see the guests to use the machine is high-speed steel or aluminum machine machine)
E. Selection of alloy saw blade cut sheet generally used 100T or 120T teeth; cutting plate or for slotting saw blades can be used with fewer teeth (eg 40T, 60T, 80T)
Question:
1) The difference between the alloy and carbide Where? A: Actually this is not the same name of each person; still others called the overall alloy saw this really the same thing is not concrete grinding wheel the same name.
2) I do not know why the basic need of high-speed hacksaw to cut aluminum sheet What is the reason? Answer: D mentioned above, because the machine is not used for the same.
Cut copper, iron, aluminum and stainless steel differences:
A, class materials are selected HSS film, when a customer calls the customer needs to know is: what used to cut material that is cut iron, aluminum, copper, or stainless steel.
B, customers can now use the saw blade is what material type? By cutting the workpiece is hollow or solid? Thickness much? And the kind of cutting machine (the machine key parameter is the number of revolutions), so we masonry blades are considering and provide information to customers purchasing recommendations (such as cutting, be sure to use stainless steel cutting blade to cut the special stainless steel, because stainless steel hardness than high.)
C, HSS film serrated teeth usually opened by the agents, (such as wholesalers can not provide open tooth, when the offer must be reported to not open the tooth and teeth to open price, in general, should be required to open the tooth plus $ 10 per piece with teeth Fee)

Saw Carbide development
1 Improved tool shape, improve cutting efficiency
Improved tool shape from the point of view to consider, first tool rigidity of the material should be increased in order to increase the discharge amount per tooth chips.
(2) develop ultra-fine grain products, to achieve stable machining
Related to high-speed milling technology point of view, high-speed milling requires tools used must have high abrasion resistance, heat resistance and good toughness. Based on this, carbide end concrete cutting blade mills new products continue to emerge, such ultra-fine grain carbide end mills used as matrix materials and conduct composite coating processing, the cutting performance is greatly improved.
Ultra-fine grain carbide is raw material for further miniaturization of the particles, the average particle size of 1μm or less, and some even as small as several nm, which can improve the flexural strength, so that it has a very excellent toughness. In turning, when the diameter of the material to be processed is small, or very small diameter end mills, because speed is limited, it is difficult for high-speed cutting. Using conventional carbide tools, easy to produce chipping, while the use of ultra-fine grain carbide cutting tools, because toughness is high, and on the cutting edge of the tool can be made large rake angle, so get a good surface finish roughness.
3 emphasis coating technology
Coating is an effective means to 12 inch saw blade improve cutting performance, companies have attached great importance to this. In coating technology, currently has a single layer to multilayer development, combining different coating materials for overlapping multilayer coating, which can effectively improve the tool cutting performance. For example, the outermost layer coated with TiN, can reduce friction with the chip; second layer is coated Al2O3, can improve the tool in front of anti-adhesion and anti-wear properties; third layer is coated TiCN, to improve the anti-wear and anti-back front wear performance.
Tool surface coating multilayer coating, the hardness of up to 2500 ~ 3000HV, heat resistance has also been greatly improved, even if cutting temperature reaches 850 ~ 900 ℃ high temperature, tool material will still not be oxidized, and maintain good hardness. Multilayer coating can improve the toughness, the surface of the tool difficult to flap wheels extend to the internal crack, therefore, can effectively prevent the generation of chipping.
The coating materials, TiC and TiN coating for high-speed cutting of steel, diamond and CBN coating has reached a practical level. The most notable is the diamond coating, in the cutting process, as the temperature rises, diamond easily decomposed into graphite, therefore, can not be used with carbon steel machining, diamond coated tool is mainly used for aluminum light alloy high-speed high-precision machining of materials.

selection of ceramic tile eight note
Glazed glaze should be smooth and delicate; shiny surface should be crystal clear glossy, matte should be soft and comfortable. A few pieces of ceramic tile color will fight together, look carefully at the light, a good product color is very small, consistent color between products; rather bad products larger color, color shades between the products.
Specifications available bandsaw blades caliper measurements. Good product specification deviation is small, after paving the product uniform, cracks between the blocks straight, good decorative effect. Poor product specifications large deviation between products of varying sizes. Deformation can be visually observed directly. Requirements products side face flat, so that the product of small deformation, convenient construction, after paving brick flat appearance.
Pattern color patterns to detailed, realistic, there is no obvious lack of color, disconnection, dislocation and other defects.
Hue hue outside the wall should be concrete cutting blade in harmony with the surrounding environment, high-rise buildings generally should not use a white or light-colored wall decorative bricks too, in order to avoid the building lacks texture; in interior, floor tiles and wall tiles tones To support each other. To sanitary ware bathroom complete the main floor tiles and a variety of accessories, including hardware and other supporting materials, quality, grade should be its coherence.

diamond tools and grinding applications
Natural diamond tools currently used mainly for copper and copper alloys and gold, silver, rhodium and other precious metals, and special parts of the ultra-precision mirror processing, such as a disk recorder, an optical mirror, a polygon mirror and the second curved mirror and so on. But its crystalline anisotropy, the tool expensive. PCD performance depends on the content of diamond grains and cobalt, cemented brick saw blades carbide tool life (WC substrate) of the tool 10 to 500 times. Mainly used for a variety of non-ferrous metals such as turning of aluminum, copper, magnesium and its alloys, tungsten carbide and wear strong fiber reinforced plastic materials, metal matrix composites, wood and other non-metallic materials. When cutting speed, feed rate and depth of cut depends on processing conditions and the hardness of the workpiece material. Synthetic polycrystalline diamond compact (PDC) properties and applications close PCD tool, mainly used in non-ferrous metals, tungsten carbide, ceramics, non-metallic materials (plastic, hard rubber, carbon rod, wood, cement products, etc.), composite materials such as cutting, gradual replacement carbide cutting tools. Because the diamond particles cutting blades bonded to ask some residual metal and graphite, in which the bonding metal or showed coalescence vein-like distribution state will reduce tool wear and life. In addition there is a metal residue solvent, solvent metal in direct contact with the diamond surface. Lower (PDC) oxidation resistance and tool heat resistance, the cutting tool is not stable enough. Thick Diamond Tool preparation process is complex, because of the low melting point metals and their alloys and diamond has a high interfacial energy between. Diamond is difficult to be generally low melting point solder alloy infiltration. Weldability poor, difficult to produce complex geometry tool, it can not be applied TDF welding tool in high-speed milling. Diamond-coated tools can be applied to high-speed machining, because in addition to diamond coated tools have excellent mechanical properties, diamond coating process can be prepared any complex shape cutters for high speed concrete saws machining aerospace materials such as aluminum alloy and refractory processing of non- metallic material such as graphite electrodes.
is to determine the hardness of the abrasive cutting disc
Abrasive cutting discs hardness is to determine the main characteristics of the performance. Abrasive itself has a very high hardness, and therefore can process a variety of high hardness materials, in particular of abrasive materials are difficult to machine materials.
