What should I pay attention to when choosing a high hardness tungsten carbide milling cutter?

PEEK is harder than PVC: the biggest feature of PEEK material is that it has a very high continuous service temperature, about 260 degrees, and excellent heat resistance and chemical stability, as well as extremely high creep strength and high toughness, which is used in piston sealing gaskets, plain bearings, valve seats, bearing sleeves, cogs, pump turbines, plug connections and sealing rings. The disadvantage is poor toughness and limited by weather conditions.

The material is mainly used in pumps, valves, seals, bearing retainers, pipes, portable lighting housings (automobile repair), brush industry, Bowden wire, dental equipment, seat slats, drilling mud core sleeves, light box covers and other fields. Generally, the hardness of nitrile rubber is divided into three kinds of Shore Shore, and different hardness can be selected according to the different sealing conditions. For the occasion of high pressure or large sealing gap, products with higher hardness should be selected, which can effectively prevent damage to the seal and prolong the service life.

However, the increase in hardness will also bring certain difficulties to the assembly, so it should be considered comprehensively. <>

When selecting materials for cemented carbide cutters, pay attention to the following points Blade tungsten carbide milling cutter production batch: when the production batch of the workpiece is very large, the rugged mold material should be selected with high quality and good wear resistance die steel, and the other skills of the mold layout have some parts and material requirements for helper layout, and they should also progress accordingly, when the batch of 45 degree tungsten carbide milling cutter is not large, you can think about low cost, and you can appropriately relax the demand for material results. 2. The results of the stamped material, the nature of the process and the conditions of the rugged die.

When the material being stamped is harder or the deformation resistance is larger, the mold convex and concave die should choose the material with good wear resistance and high strength, and the cold extrusion die with poor conditions of the rugged mold, beck tungsten steel milling cutter should be selected to have sufficient hardness, strength, patience, wear resistance and other inductive rigid results of the die steel, together with a certain red hardness and thermal strength. 3. For material results, we should consider the cold and hot processing results of the mold and the existing conditions of the factory Tungsten carbide milling cutter production and use the environment. In short, the choice of cemented carbide tool material is a very large question, and even if it is saved under the premise of ensuring the skill demand, it should be used as the general criterion for us to choose the mold material.

The parameters of milling stainless steel will be affected by many factors, such as the material, hardness, size, processing method, stability of the machine tool, and so on. Therefore, I can't give a completely accurate parameter suggestion, here are some parameter suggestions that are used in general:

Appropriate cutting speed: It is recommended that in the range of 50-150 meters, the higher the hardness of stainless steel, the slower the cutting speed should be.

Appropriate feed rate: It is recommended to be in the range of millimeters of teeth.

Appropriate cutting depth: It is recommended to be in the millimeter range, depending on factors such as the hardness, material and machining method of the workpiece.

Choosing the right coolant: Choosing the right coolant can improve cutting efficiency, reduce tool wear and extend tool life. It is recommended to use cutting fluids or cutting oils, etc.

It should be noted that these parameters are only some general reference values, and the specific parameters of solanka need to be adjusted and optimized according to the actual situation. In the process of machining, it is necessary to check the wear and tear of the tool in time to avoid problems such as excessive wear and tear leading to the decline of processing quality or tool breakage.

The thermal conductivity of stainless steel itself is low, and when cutting, the turning speed of the tool can not be high, and it is easy to burn the tool when it is high, and the machined parts in the noisy state are also easy to deform. Therefore, in the cutting of stainless steel, the cutting speed should be adjusted slower first, and then adjusted according to the specific situation of cutting.

It is recommended to go to the tool manufacturer to work for half a year, learn all the technology at home, and then do it yourself

Hello, the raw material used in tungsten carbide milling cutter is cemented carbide, commonly known as tungsten steel. Tungsten carbide milling cutter is generally made of cemented carbide round bar material, generally using CNC tool grinder for processing equipment, gold steel grinding wheel for processing tools, through the computer or G** processing route once formed and manufactured, this processing method has high efficiency and high precision. The raw material used in high-speed steel milling cutters is high-speed steel.

High speed steel needs to undergo a heat treatment process to improve its own hardness. By weight, because the density of tungsten carbide (tungsten steel) is much higher than that of high-speed steel, the weight is much heavier, so the first feeling is only by feel, followed by listening to the sound, because it is an old knife, you can knock it on each other, the sound of tungsten steel should not be crisp, it is muffled! In addition, the hardness of the hardness is observed by tapping.

Hello, the hardness and red hardness of tungsten carbide milling cutter and high-speed steel milling cutter are different, and the cutting speed of processing is also different. The machining efficiency of tungsten carbide milling cutters is 4 10 times greater than that of high-speed steel milling cutters.

Dear, I am glad to answer for you: Is the hardness of the machining stainless steel milling cutter as high as possible Answer: The choice of tool material has a great impact on the tool life, processing efficiency, processing quality and processing cost.

The hardness of the tool material must be higher than the hardness of the workpiece material, and the general requirement is more than 60HRC. The harder the tool material, the better the wear resistance. (2) Strength and toughness.

The tool material should have high strength and toughness to withstand cutting forces, shocks and vibrations, and prevent brittle fracture and chipping of the tool. (3) Heat resistance. The tool material should have good heat resistance, be able to withstand high cutting temperatures, and have good oxidation resistance.

4) Process performance and hand-destroying economy. The tool material should have good forging performance, heat treatment performance and welding performance; grinding performance, etc., and to pursue a high performance ratio. Thank you for your patience.

The above is my full reply, if you are satisfied with my service, please give a thumbs up, and I wish you all the best! Peace and joy!

Tungsten steel cutter hardness indicates the ability of a material to resist hard objects pressing into its surface. It is one of the important performance indicators of metal materials. Generally, the higher the hardness, the better the wear resistance. Gaoluo Precision Mould Company tells you that the commonly used hardness indicators are Brinell hardness, Rockwell hardness and Vickers hardness.

1. Brinell hardness (hb).

With a certain load (generally 3000kg) to a certain size (diameter is generally 10mm) of hardened steel balls pressed into the surface of the material, keep for a period of time, after loading, the ratio of the load to its indentation area, that is, Brinell hardness value (HB), the unit is kilogram force mm2 (n mm2).

2. Rockwell hardness (hr).

When the HB > 450 or the specimen is too small, the Brinell hardness test cannot be used and the Rockwell hardness measurement is used instead. It is to use a diamond cone with a top angle of 120° or a steel ball with a diameter of , under a certain load, to press into the surface of the measured material, and the hardness of the material is calculated from the depth of the indentation.

According to the hardness of the test material, it is expressed in three different scales:

HRA: It is the hardness obtained by using a load of 60kg and a diamond cone presser, and is used for extremely hard materials (such as cemented carbide, etc.).

HRB: It is the hardness obtained by using 100kg load and diameter hardened steel balls, and is used for materials with lower hardness.

Such as annealed steel, cast iron, etc.).

HRC: It is the hardness obtained by using 150kg load and diamond cone presser, and is used for materials with high hardness (such as quenched steel, etc.).

3. Vickers hardness (HV).

With a load of less than 120kg and a diamond square cone press with a top angle of 136°, the surface area of the material indentation pit is divided by the load value, which is the Vickers hardness hv value (kgf mm2).

The material is generally a combination of tungsten carbide and cobalt powder, and the particle size and uniformity are mainly measured to judge the quality of the material. The hardness is generally pressed into the tested tool with a Rockwell hardness machine, which is generally around HRA90. However, the coating hardness of the general coated tool coating is very high, and it can reach HV3000, so the hardness should be measured to measure the tool holder.

These equipment and testing all cost a lot of money, and the general tool can only be bought from the perspective of wear resistance in use to evaluate the quality of a knife.

The raw material of tungsten carbide milling cutter is cemented carbide which is equal to tungsten steel. Tungsten carbide blank production ingredients:

There are two kinds of TAP powder (WC, TIC), and the particle size of these two powders is generally6un.Powder (TAP WC) particle size + trace elements + cobalt (OC) + binder =

Tungsten carbide [stirred in the machine to form]. ATP powder (TAP WC) is the main ingredient and is closely related to the hardness of tungsten carbide milling cutters. The finer the particle size of TAP powder, the higher the hardness and the more wear-resistant, on the contrary, the harder the rougher, the more brittle the Qianshan and the worse the bending resistance.

When sharpening the knife, do not open a short flute to make the tungsten carbide knife durable.

Cemented carbide tools (especially indexable carbide tools) is the leading product of CNC machining tools, some countries have more than 90% of the turning tools, more than 55% of the milling cutters are made of cemented carbide, and this trend is still increasing. Since the 80s of the 20th century, the tool industry has continued to expand the production of various solid and indexable carbide tools or inserts, and its varieties have been extended to the field of various cutting tools, among which the indexable carbide tools have been expanded from simple turning tools and face milling cutters to various precision, complex and forming tools. Tungsten carbide is also a common material used to make general-purpose tools such as drills and face mills.

At the same time, the use of cemented carbide for complex tools such as reamers, end mills, medium and large module gear cutters for machining hard tooth surfaces, and broaches is also increasing. The annual output value of cemented carbide tools and inserts has accounted for more than 30% of the total output value of cutting tools.

Don't break the chips, it will be a little more durable, but the iron filings that come out are not easy to break and are easy to get entangled in the workpiece.

Add the appropriate coolant, reduce the cutting speed, and increase the cutting volume appropriately to compensate for the efficiency.

Tungsten steel knives, at present, refer to the tungsten steel of the blade of the machine clamp knife!! I've never heard of tungsten carbide knives sharpened!! Generally, white steel bars and cemented carbide need to be ground by hand!
