a blade made from two dissimilar metals; steel spring backing with high-speed steel edge material welded to tips of the teeth. the high-speed steel often contains 8% cobalt for extreme wear characteristics.

advantages of a bi-metal (matrix) blade inclue fatigue resistance. resists back edge swaging. operates at high band tension for straighter cuts versus carbon steel blades. reduction in blade hardness occurs at about 1300 f

Skiving is one of the important preparatory operations carried out in the fabrication of leather goods. Skiving is also known as paring in leather goods terminology. Skiving operation is done mainly to reduce the thickness of the cut components of the leather material mostly at the edges to varying width in different ways to suit the methods of construction, in the manufacture of leather goods. Except in cut edge construction, in all other fabrication work, skiving is invariably done.

Skiving is necessary for fancy leather goods making. It is performed by machine in modern factories, machines of the cylindrical knife type being the most popular. For some classes of leather goods the reduction of leather substance by the machine alone is sufficient for the subsequent assembling processes. In other grades of articles the machine operation is followed by hand skiving. Knife is used to effect the future reduction necessary for turning over rounded corners, and for touching up the machine pared parts. The feather edging and fine edging of the leathers are usually carried out with the hand knife.

When correctly adjusted and operated, the skiving machine produces a very uniform reduction of substance. Hard and thick leathers can be as evenly pared as those of soft texture, and the reduction of large areas is performed more satisfactorily and with less risk of damage then with hand knife. As a labor saving appliance, the machine is remarkable; a time factor of roughly 90 percent for straight forward skiving is in favor of the machine as compared with the hand process.

bimetal blades are metal cutting blades. they are used on band saws to cut carbon steel, tool steel, structural steel, stainless steel, pipes and tubes, die steel, angles and flat stock, and mixed metal applications. our clients who use these metal cutting bandsaw blades include steel service centers, small to large manufacturers, fabricators, maintenance shops, job shops, tool and die shops, and anyone interested in saw cutting a broad range of shapes, structures, and solids.

m42 grade refers to the grade of the hss tooth used in the bimetal configuration. m42 grade steeels are better suited for cutting iron and soft steels.

Carbon Flexback blades are a low cost alternative on easy to cut material. Carbon Flexback blades have an excellent fatigue factor to give long saw blade life on bandsaws running at high speed, cutting non-ferrous metal, and wood. Its flexible backer is also suitable for absorbing contour cutting stresses.

These bandsaw blades are made from a solid piece of carbon steel with a flexible back. Their teeth are heat treated to retain their sharp edge.

pink fused aluminaiswhite fused aluminawith chrome oxide (under 0.5% cr2o3) has been added in the fusion process to produce a grain that is slightly tougher than regularwhite fused aluminaused for grinding unhardened high alloy steels. If more chrome oxide (about 3% cr2o3) has been added to, it will get ruby fused alumina, which provides additional toughness overpink fused alumina.

the raw material and refining work ofpink aluminum oxideare basically the same as white aluminum oxide. They are both needed to add cr203 and well mixed to be refined as abrasives with rose red color. Its hardness is close to white corundum, and the roughness is higher than white aluminum oxide. It is suitable for grinding knifes, measuring tools, meters, screw etc. That require low roughness.

most grinding wheels are made with vitrified bonds, which consist of a mixture of carefully selected clays. At the high temperatures produced in the kilns where grinding wheels are made, the clays and the abrasive grain fuse into a molten glass condition. During cooling, the glass forms a span that attaches each grain to its neighbor and supports the grains while they grind.

aluminum oxide is the most common abrasive used in grinding wheels. it is usually the abrasive chosen for grinding carbon steel, alloy steel, high speed steel, annealed malleable iron, wrought iron, and bronzes and similar metals. there are many different types of aluminum oxide abrasives, each specially made and blended for particular types of grinding jobs. each abrasive type carries its own designation-usually a combination of a letter and a number. these designations vary by manufacturer.

Doctor Blades are manufactured in a wide range of sizes and shapes. Steel blades can range from .004 (0.10mm) to .010 (0.25mm) in thickness. They can also have special shapes to fit the application. The most used shape in both gravure and flexo is called a lamella tip. This tip is a reduced step area that is typically .060 (1.4mm) wide and is usually of the base metal thickness. A typical blade that is widely used is .006 (0.15mm) thick with a .003 (0.075mm) thick lamella (reduced step). The lamella (reduced step) allows the doctor blade to meter very fine ink cells without leaving any ink in the areas of the cylinder that are not designed to print. Doctor blades and printing cylinders can range in length from 7 up to 120. The small sizes can print labels and other small printing jobs, while the largest sizes are for printing the very high volume publication and packaging items.

adiamond grinding cup wheelis a metal-bondeddiamond toolwithdiamond segmentswelded or cold-pressed on a steel (or other metal, such as aluminum) wheel body, which usually looks like a cup. diamond grinding cup wheels are usually mounted onconcrete grindersto grind abrasive building materials like concrete, granite and marble.

there are various styles and specifications of diamond grinding cup wheels to fit various application requirements. the ones with many big diamond segments can undertake heavy workloads, for example, grinding concrete and stone, while those with small or sparse diamond segments are normally used for fast removal of paints, wallpapers, glues, epoxy and other surface coatings.

just like other metal-bonded diamond tools, the diamond segments on diamond grinding cup wheels can have different bonds, different diamond grits, different diamond quality and different diamond concentrations to fit different uses. for example, if the material to be ground is hard, the bond should be softer, and if the material is relatively soft, the bond should be harder.

diamond grinding cup wheels are used in different-roughness grindings. for coarse grinding, the bond should be softer and the diamonds' quality should be higher, because in this case the diamonds become blunt more easily. the diamond grit should be bigger, normally from 35 grit to 50 grit. for this is coarse grinding and big grit can improve working efficiency. the diamond concentration can be lower.

for fine grinding (sometimes called "polishing"), the bond should be harder and the diamonds' quality can be lower, as in this case the diamonds can last longer and a hard bond can also help the precision of the process. the diamond grit is normally between 80 grit and 120 grit, depending on the grinding requirements. the diamond concentration should be higher.

after being ground, the material can be further polished with resin-bonded diamond polishing pads of different diamond grits.
