Q:Carbide drills and cobalt high speed steel bit, which is good? What's the difference between these two materials?

The two materials are not good or bad, the key is to look at the application!!Carbide drill, high hardness, wear resistance, high efficiency, toughness slightly worse, therefore, the rigidity of the machine tool and spindle runout and speed are required!Cobalt high speed steel including ordinary high-speed steel, good toughness, edge processing can be very sharp, more suitable for processing some sticky materials, of course, low strength materials will be nothing difficult, but its high temperature resistance, wear resistance is relatively poor, the drilling speed is not high!!Therefore, the choice of drill or according to your working conditions to choose,

Q:We'll drill on the stainless steel column. Which bit is better?

If it's cylindrical carbide, it's better to be on the drill bit or as a guide

Q:What is the difference between tungsten cobalt alloy and YG8 and YG6 series cemented carbide?

YG6, YG6X, YG8, YG8C, YG11C, and so on,YG6 hardness and wear resistance are slightly higher than that of YG8, but strength and toughness are not as good as YG8

Q:The difference between cemented carbide and tungsten.

Tungsten steel (hard alloy) with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.Also known as tungsten steel, hard alloy, refers to the sintering of the composite materials containing at least one metal carbide. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, tantalum carbide is tungsten steel common components. The grain size of the carbide component (or phase) is usually between 0.2-10 microns, and the carbide grains are bonded together with metal binders. Binder usually refers to metal cobalt (Co), but for some special purposes, nickel (Ni), iron (Fe), or other metals and alloys can also be used. The composition of an undetermined carbide and bond phase is called "grade"".

Q:I would like to use carbide cutting tools, car work, ordinary A3 steel or 45 steel, lathe speed to play more appropriate, the workpiece surface quality is better?

The surface quality is good, the blank diameter is 50MM. Can play around eight hundred rpm.When the car is refined, 1200r/min

Q:Do you want to center hole? How deep is fit? Or do not hit it directly? My drill bit and the center hole contact point are easy to collapse

A very shallow point can be;Because once too deep, and the center hole of the aperture is less than the drill bit to drill aperture, so is not in contact with the workpiece, but the main cutting edge part in contact with the workpiece, so cause drill can not correctly centering, so easy to collapse;In the deep hole processing, it is necessary to use pre hole; the general pre hole is the drill bit, the hole size is the same, and the depth is usually about 3 times;I hope I can help you

Q:Hard alloy and cast iron join together, use temperature 150 degrees, what glue is better to use?

High temperature resistant high strength metal and carbide inorganic adhesive YL04-3. For the structure of all kinds of cutting tools such as bonded &def hard alloy cutter and lengthened drill, geological drill; casting airhole crack repair; use temperature of -196 DEG ~800 DEG

Q:There are three kinds of cemented carbides, of which tungsten, cobalt and titanium are brittle cemented carbides?

[classification of cemented carbide] ISO carbide carbide cutting into 3 categories: P, K and M.1, P class (equivalent to China's YT class) cemented carbide by WC, TiC, and Co composition, also known as tungsten titanium cobalt carbide. This kind of alloy is mainly used for processing steel materials. Common brands are YT5 (mass fraction of TiC is 5%), YT15 (mass fraction of TiC is 15%), with the mass fraction of TiC increased, the mass fraction of cobalt decreased, hardness and wear resistance increased, bending strength decreased. This kind of hard alloy is not suitable for processing stainless steel and titanium alloy.2, K class (equivalent to China's YG class), carbide composed of WC and Co, also known as tungsten cobalt carbide. These alloys are mainly used to process cast iron, nonferrous metals and their alloys. The common grades are TG6 (cobalt mass fraction 6%) and YG8 (cobalt mass fraction 8%). As the mass fraction of cobalt increases, the hardness and wear resistance decrease, and the flexural strength and toughness increase.3, M class (equivalent to China's YW class), carbide is based on WC, TiC, Co, and then added TaC (or NbC) and into. After the addition of TaC (or NbC), the comprehensive properties of cemented carbide were improved. Such cemented carbide can be used for both cast iron and non-ferrous metals, as well as for steel and for high temperature machining

Q:The difference between HSS and carbide knives

High speed steel which is mainly used in the rapid operation of the machine, its good fatigue performance, high temperature performance is better, but the hardness is generally hard alloy steel mainly refers to alloy steel with high hardness, high hardness of the steel is mainly emphasized in a certain range, but may be brittle or will be relatively large, high performance high temperature, poor.

Q:How to distinguish the authenticity of Zhuzhou diamond brand cemented carbide blade?

Zhuzhou diamond brand cemented carbide blade is the first brand in our country. We can distinguish its authenticity from the following aspectsVisual package: it is packed in plastic box, the upper and lower cover are transparent plastic, and the bottom box is blueNormative labels: according to the ISO standard, lists the recommended types of processing materials, bar code identification, marked "diamond brand" trademark and "China well-known trademark" and enterprise logoType anti-counterfeit: each piece of hard alloy welding machine, clamping blade convex superscript "ZCCT" logo, direct press formingSealing anti-counterfeiting: labels and sealing paste affixed to the interface of the packaging box, one-time paste, can not be pasted after tearingZhuzhou Jing Jing carbide sales Co., Ltd.
