In the metal cutting process, tool wear always occurs, tool wear and tool material, the nature of the work-piece material and cutting conditions are related. Tool wear can be divided into two categories: normal wear and abnormal wear. In normal cutting conditions, the basic form of tool wear is shown as edge wear, front face wear, rear face wear and tip wear. Abnormal wear forms, manifested as tool breakage, plastic deformation and so on. The main reasons of tool wear are as follows. 1, hard point wear Because the material contains some carbide, nitride, chip tumor residue and other quality point impurities. 2, bonding wear machining process, chip and tool contact surface at a certain temperature and pressure, plastic deformation and cold welding phenomenon, the tool surface bonding point is chip away and the wear occurs. 3, diffusion wear Due to the high temperature effect when cutting, the tool and the work-piece material in the alloy elements of mutual diffusion, and cause tool wear. 4, oxidation wear carbide tool cutting temperature of 700-800 ℃, some carbon in the tool, cobalt, titanium carbide, such as air oxidation, the formation of a layer of lower hardness in the tool surface oxide film, when the oxide film wear off in the tool surface caused by wear. 5, phase change wear in the cutting of high temperature, the tool metallurgical organization changes, thus causing a reduction in hardness caused by wear. Tool in the intermittent cutting conditions, due to strong mechanical and thermal shock, more than the tool material strength, will cause tool breakage. Under the effect of alternating mechanical loads, the fatigue strength of the tool material is reduced, easily causing mechanical cracks and breakage. There are many factors affecting tool life, which are mainly summarised in 5 aspects: work-piece material, tool material and its geometrical parameters, cutting dosage, tool sharpening quality, lubrication and cooling conditions.

Carbide saw blades are the most commonly used cutting tools for wood product processing, and their quality is closely related to the quality of processed products. The correct and reasonable selection of carbide circular saw blades for wood is of great significance for improving product quality, shortening processing time, and reducing processing costs. Tungsten carbide circular saw blades include the parameters, such as the saw tips grade, the material of the body, the tooth shape, the angle, the diameter, the number of teeth, the thickness, the bore size, and other parameters. These parameters determine the processing capacity and cutting performance of the saw blade. Today I will share some tips when we choose a tungsten carbide saw blade, the following parameters of the saw blade should be selected correctly according to the needs. Choose carbide tips grade Because tungsten-cobalt-based cemented carbide has better impact resistance, it is more widely used in the wood processing industry. The commonly used model in wood processing is YG8-YG15. Selection of saw blade tooth type The tooth type of the circular saw blade is divided into left and right teeth, tapered teeth, flat teeth, trapezoidal teeth, crescent teeth, etc. In actual use, the choice is mainly based on the type of raw material being sawed. The left and right teeth are suitable for opening and horizontal sawing of various soft and hard materials and particle boards. Tapered teeth are often used in the slot saw blades of panel saws. Flat teeth are mainly used for the sawing of ordinary wood. This kind of saw blade has a lower cost but is a rougher saw. The combination of trapezoidal teeth and flat teeth can also obtain high cutting quality without slotted saw blades, and there will be no veneer cracking during sawing. It is suitable for sawing various double-veneer wood-based panels. Choice of saw teeth angle The angle parameter of the saw teeth part is more complicated, and the correct selection of the angle parameter of the saw blade is the key to determining the quality of sawing. The most important angle parameters are rake angle, rear angle, and wedge angle. The number of saw teeth Gener

In most cases, there never will be one cutting tool insert solution that works for everyone. There are too many variables with respect to different machines, various cooling ways, cutting parameters, machining environments, and work pieces material. For example, we had a customer needed inserts for milling carbide bar, in most cases the customers are using CBN inserts for milling carbide. And he also tried CBN inserts to do the job, but the results not met his expectation. Under this situation our engineer suggested to use PCD inserts. He has taken our suggestion, and PCD inserts works very well for him. As we all know PCD inserts are usually use on aluminum. As a conclusion, if we wanted a most satisfied cutting tool the testing must needed in different chip breakers, grades and materials.

There are many factors that influence the lifetime of cutting tools such as the composition of raw material, machining data, design of products etc. However, we usually ignore the fact that coating also hold an important position on the lifetime of tools.   Coating Name Color Hardness Max service temperature Friction coefficient Application Area AlTiN Black 3500HV 900°C 0.40 Suitable for tools hardness greater than HRC45 TiAlCrN Purplish red 3500HV 900°C 0.40 Suitable for tools hardness less than HRC45 TiAlSiN Black 3800HV 1000°C 0.40 Suitable for high speed and high hardness dry or wet cutting TiAlN Purple 3000HV 800°C 0.40 Suitable for tools hardness less than HRC45 Nano Black Black 4000HV 1200°C 0.45   Nano Blue Blue 4000HV 1200°C 0.45 Suitable for tools hardness greater than HRC55 TiN Gold 2500HV 600°C 0.50 generalcoating for tool and dia materials TiSiN Bronze 3800HV 1100°C 0.25   Nano TiSiN Bronze 4000HV 1200°C 0.25   DLC Black 2500HV 300°C 0.10   The following is the result by our customer: Coating:TiSiN                   Workpiece:SKD11 Vc:100m/min  Fn:0.2mm/r ap: 10mm ae:0.3mm      Our tools                      From A company           From B company Related search keywords: coating for cutting tools, ceramic coating for cutting tools, diamond coating for cutting tools, types of coating for cutting tools, coating technique for cutting tools, coatings for cutting tools, cutting tool coatings, cutting tool coating, cutting tools coating, tool coating, types of coating on cutting tools, coating process, high-performance coatings for cu
