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

The hard alloy bit too brittle is not recommended to use the titanium cobalt drill hardness is 12 degrees lower than the hard alloy but the impact is far better than other aspects of hard alloy, so I recommend the titanium cobalt drill, processing all kinds of materials, as long as the titanium cobalt drill deal, hard alloy as the game, looking for experience in practice, there are the problem can contact my 12 years of experience in fitter

Q:HSS clip can clamp the hard alloy saw it

According to S=Vc/ (pi * saw diameter).Extended introduction:product mixMonolithicThe cutter body and the cutter tooth are made into a whole.Integral welding gear typeThe tool tooth is made of hard alloy or other wear-resistant tool material and brazed to the cutter body.Inserted toothThe cutter teeth are fastened on the cutter body by mechanical clamping method. The replaceable cutter tooth can be the cutter head of the whole cutter material, or the cutter head of the welding tool material.

Q:How are hard alloy fittings machined and polished?

Cutting tools or ceramic cutting tools for cubic boron nitride material, cobalt alloy cutting tools, etc.,Diamond grinding materials for polishing.

Q:What are the standard units of measurement for carbide inserts?

Manufacturers usually use KG, which is used inside the shop

Q:Can CBN wheels grind cemented carbide? Why?

Cubic boron nitride grinding should not hard alloy and non-metallic hard materials in grinding, high temperature, CBN in alkaline aqueous solution will produce a chemical reaction, CBN wheel can be decomposed in 300 DEG C in alkaline solution, can trace decomposition in boiling water, the crystal grains were damaged, so the grinding, can only use oily the cooling liquid, and can not use water-based coolant.CBN wheel grinding for mild steel, heat-resistant steel, high hardness alloy steel precision grinding and finish grinding. The special steel products such as tungsten, molybdenum and cobalt high speed steel, alloy steel, high-speed steel with special grinding, super finishing machining of heat-resistant parts, and other steel quenching workpiece grinding line.

Q:Carbide yk20? What do you mean?

Cemented carbides YK20, Y represent alloy categories - tungsten cobalt, K20 represents cobalt contentDensity g/cm3:14.30-14.60;The hardness of HRA is more than or equal to 86.5;The shear strength is greater than or equal to N/mm2:2350,Performance and usage: with high toughness and wear resistance, suitable for embedding percussive rotary drilling bit, drilling in hard and tight hard rock.

Q:Would you like to ask me if the hard alloy can be polished with ordinary metallographic sand paper? Well, what kind of sandpaper does it usually start with? Thank you!

Hard alloy is too high and can not be polished by ordinary metallographic sand paper. It should be put on the machine tool by diamond grinding wheel, and the cost is also very cheapReally manual grinding, then you can add grinding cream to try, but the efficiency is very low

Q:Make cutting dosage

But modern machining, has no strict distinction between the T and G class, but in different types of processed materials and processing conditions, different ways such as the use of different materials, and with appropriate coating, to reduce the cost requirements.Cutting parameters need to be selected according to different cutting occasions and different materials to be machined.

Q:Can ceramic tools process cemented carbides?

No, ceramic cutters are usually used to process cast iron (high speed machining) and high hardness steel (Cui Huogang).Generally, the hardness of ceramic tools reaches HRA91-95, while the hard alloy can reach HRA93.The main components of ceramic tool materials are Al2O3 with high hardness and melting point. Si3N4 and other oxides and nitrides, and then added a small amount of metal carbide, oxide or pure metal additives, formed by pressing, sintering, and then a tool material. Its hardness can reach HRA91 ~ 95, and the hardness of HRA80 can still be kept at the cutting temperature of 1200 DEG C. In addition, the chemical inertia is large, the friction coefficient is small, and the wear resistance is good, and the service life of the processed steel pieces is 10~12 times of that of the hard alloy.Its major disadvantages are brittleness, low bending strength and low impact toughness. Therefore, it is mainly used for semi finishing and finishing, high hardness, high strength steel and chilled cast iron and other materials. Commonly used ceramic cutting tools are alumina ceramics, composite alumina ceramics and composite silica ceramics.Taiwan is hard gold metal carbide with high heat resistance and high wear resistance (WC tungsten carbide, titanium carbide, tantalum niobium carbide TiC TaC, NbC etc.) and metal binder (cobalt, nickel and molybdenum) powder metallurgy products under high temperature sintering. The hardness of HRA8 9 ~ 93, 850 ~ 1000 DEG C high temperature resistant, has good abrasion resistance, allowing the use of the cutting speed can reach 100 ~ 300m / min, can be a variety of materials including machining hardened steel, therefore it is widely available.
