There are five categories YT alloy alloy grades, namely YT30, YT05, YT15, YT14, YT5. This five kinds of material processed alloy grades are not the same.

Tungsten Carbide Cutting Tools Welding Flux

Tungsten carbide cutting tools welding uneven heating occurs if a good part of the welding and the other part of the welding bad phenomenon that reduces weld strength. After reaching the temperature for soldering alloy sheet according to the size, should be incubated for 10 to 30 seconds so that the surface of the cemented carbide tools, welding temperature uniformity. The main role of soldering flux carbide alloy sheet is to prevent the surface of the groove in the insert and the heating and oxidation, and to carbide precipitation of impurities in the welding material to facilitate the formation of scum carbide welding tool. In addition to the liquidity of tungsten carbide cutting tools welding flux welding surface allows good wetting, increased carbide welding materials.

Welding Material Requirements of Tungsten Carbide Cutting Tools

Tungsten carbide weld material to be formed has sufficient plasticity so that the solder itself by plastic deformation of the stress relief part of the welding; appropriate melting point of solder, weld metal is lower than the melting point of at least 40 ° to 60 ℃ but requires higher than the operating temperature of weld 300 ℃, this way you can ensure that the tool can work in high-speed cutting time. Under the conditions allowed, should try to reduce the melting point of the solder to reduce heat stress and deformation welding carbide cutter body because heat generated.

How Welding Tungsten Carbide Cutting Tools

Tungsten carbide cutting tools welding and tool steel, high speed steel cutting tools welding is not the same, this is due to the performance of the big differences between steel and carbide caused. Especially steel and tungsten carbide thermal conductivity and thermal expansion coefficients are not the same, tungsten carbide cutting tools welding, it tends to heating or cooling too fast welding of carbide cutting tools which easily lead to stress too much so that the tungsten carbide insert a crack. The larger sizes tungsten carbide inserts, tungsten carbide blade cracking phenomenon is also the more serious. When welding tungsten carbide tools should satisfy a requirement. One is tungsten carbide weld strength must be sufficient to ensure that the maximum amount of tungsten carbide cutting tools, and furthermore is not allowed to have a crack on the tungsten carbide blade.

Tungsten Carbide Tool Wear And Damage

As the tungsten carbide cutting process inevitably passivation passivation later changed the original carbide tool geometry and normal cutting, this time had to be transferred for sharpening or replacement pull tool cutting edge. Carbide Tool passivation two main reasons, the first carbide passivation reason may be because of tungsten carbide cutting tools in the process of cutting, because the workpiece - tool - chip contact zone occurs strongly friction resulting in tungsten carbide cutting tools such as front, flank and other surface materials are some parts of the chip or the workpiece material is gradually worn away and suffer. Tungsten carbide tool wear is an inevitable phenomenon.

How to Protect Solid Carbide Milling Tools

Solid carbide milling tools are manufactured with a sharpened carbide grinding, cutting tools have lasting, extremely sharp edges. CNC milling machine for sharpening carbide tools, carbide cutters, drills, carbide saw blades. If you simply throw a super-sharp tool kit, these techniques could endanger workers' fingers. Solid carbide milling tools, such as those used in CNC machine tools, has a very sharp cutting edge with a groove. For these tools to work properly, carbide edges must be kept sharp, no scratches or abrasions.

How Self-Tungsten Carbide Drill

If less than 2mm can be found tungsten carbide blade, such as a thin cutting blade used lathe, if more appropriate, generally available cemented carbide inserts with a cutting blade suitable for cutting machine to use, and then welded to the accompanying drawings in design corresponding round rod, drill bit better than the small drilled holes, with a diameter at least as large. Usually, after coarse grinding can be used by hand. If required hole diameter precision grinding machines available (tool grinder), and then use hand geometry and grind each cutting flutes. The diamond drill bit slightly smaller than the apex angle is appropriate, to repair a small chisel grind so easy when drilling hollow, to prevent swinging. Such tungsten carbide drill applies only to the depth of drilling hardened parts is not deep holes.
