Is the YT15 knife not easy to use? Oh, I'm in trouble!

1. The differences between milling inserts YT5, YT14, YG8 and YW2 inserts are as follows:

1. The strength is different.

YT5 has the highest strength, the highest impact and vibration resistance among YT alloys, and is not easy to chipping during the cutting process; YT14 has higher use strength and better vibration resistance, which is slightly worse than YT5; The use intensity of YG8 is higher, and the intensity decreases sequentially. The strength of YW2 has been increased again, and it can resist huge impacts.

2. The wear resistance is different.

YT5 has poor wear resistance, so it is often used for rough machining; YT14 has stronger wear resistance than YT5, faster cutting speed, and better performance in terms of wear resistance; YG8 has poor wear resistance and slower cutting speed during machining; YW2 has poor wear resistance.

3. The hardness is different.

The hardness of the better strength, that is, the better impact resistance, is not high, so the hardness of YT5 and YW2 is not high, and the hardness of the material should not be too hard when processing, and the remaining two hardness are higher.

Second, the scope of application:

YT5 use: used for carbon steel and alloy steel, used for rough turning, rough planing, rough milling, drilling and other purposes;

YT14 use: used for carbon steel and alloy steel, used for rough turning, rough gouging, rough milling, drilling and other purposes;

YG8 uses: used for cast iron, non-ferrous metals and non-alloy materials processing, turning, planing, milling, drilling and other purposes;

YW2 uses: suitable for heat-resistant steel, high-fierce steel, non-resistant steel, alloy steel, and difficult-to-machine materials, and also suitable for rough and semi-finishing of ordinary steel and cast iron.

It is often said that:

YT15 wrought iron finishing turning tool, YG8 pig iron knife.

The letters indicate the alloying elements contained in the knife grade, and the numbers indicate the content.

All belong to cemented carbide, YT15 belongs to tungsten cobalt titanium alloy, YG8 is tungsten cobalt alloy, due to the titanium element added to YT15 to improve the hardness, but the higher the hardness, the more it is not resistant to impact, so generally YT15 is used to make fine knives, and the hair knives are used with YT5, YG8 is impact-resistant and wear-resistant.

In general, G8 can be used to make wrought iron knives, but YT series can not be used for pig iron processing, for example, it is better to use G8 knives for steel castings, because steel castings generally inevitably have trachoma, cracks and other defects, and G8 can also be used for stainless steel processing.

If YT15 is used to make pig iron, then because YT15 is not wear-resistant, pig iron is like an abrasive, YT15 props can still be used as pig iron at a particularly low speed, but the effect of YG8 cannot be achieved.

Due to the wear of the tool, the YT15 knife will be the processing surface of the pig iron, through the grinding you will find that the YT15 knife is better than YG8 grinding, the reason is that the YG8 wear resistance is higher, now we generally do not use YT15 this brand of knives, the hair knife uses YT5, the impact resistance is good, the fine knife uses YA6, the use effect is very good at high speed, or YT726, these two grades must be high-speed, some people like to use YS8, this grade is super hard, but very brittle, Must be high-speed, continuous cutting, in the drawings require a high finish when we use imported machine clamping tools, generally is the highest speed that the machine tool can achieve, comparable to the roughness of grinding.

Milling Insert YT5 The insert is milled pig iron, and the insert and YG8 are milled cast iron or non-ferrous metal materials

YT5 has good resistance resistance, which means that the blade is not easy to break but easy to burn, and the YT14 blade is not easy to burn but easy to break!

It is recommended that if you have pig iron, it is best to use YT5, and if you want cast iron, use YG6!

YT5 characteristics: among YT alloys, it has the highest strength, the highest impact and vibration performance, and is not easy to jump on the edge, but it has poor magic resistance.

Uses: used for carbon steel and alloy steel, for rough turning, rough planing, rough milling, drilling and other purposes.

YT14 features: high use strength, good impact and vibration performance, but worse than YT5, magic resistance and cutting speed are stronger than YT5.

Uses: used for carbon steel and alloy steel, for rough turning, rough planing, rough milling, drilling and other purposes.

YG8 characteristics: high use strength, poor magic resistance and cutting speed.

Uses: used for cast iron, non-ferrous metal and non-alloy material processing, turning, planing, milling, drilling and other purposes.

YW2 characteristics: high strength, can withstand strong impact resistance.

Uses: Suitable for heat-resistant steel, high-fierce steel, non-resistant steel, alloy steel, and difficult-to-machine materials, and also suitable for rough and semi-finishing of ordinary steel and cast iron.

YT class - carbon steel, YW class - alloy steel, YG class - cast iron.

YT tungsten titanium cobalt cemented carbide.

The content of TIC in YT14 and YT15 heads is 14% and 15%, respectively, and the content of CO is 8% and 6%, respectively.

With the increase of TIC content and the decrease of CO content, the hardness and wear resistance of the cutter head are improved, and the flexural strength, especially the impact toughness, is significantly reduced.

YT15 YT14 can be YW2 OK This is the processing of stainless steel wide side touch on the cutter head has a type of lease number If not, you can grind and try YT15 or something is not very good to grind Easy to collapse The machine clamp knife is the same As long as it is not a cautious talk about counting cars.

Generally, YT15 is also used, and YW2 G8 is generally wear-resistant, but not bright, and its model is generally marked.

(1) These two are only different from the titanium content, YT14 contains 14 titanium, and the other one contains 15 titanium.

2) YT14 YT15 are alloy insert grades, YT15 is suitable for the finishing of steel and cast steel, and it is advisable to use medium feed and high cutting speed; YT14 is suitable for semi-finishing of steel and cast steel.

YT14 YT15 are alloy insert grades, YT15 is suitable for the finishing of steel and cast steel, and it is advisable to use medium feed and high cutting speed; YT14 is suitable for semi-finishing of steel and cast steel.

YS8 tungsten carbide is suitable for iron-based and nickel-based superalloys.

Finishing of high-strength steels. density, flexural strength.

1620n mm3, hardness.

YW2 cemented carbide contains a large amount of CO (about 8%), so the flexural strength is high (approx., but the hardness is slightly lower, and is generally used for roughing and semi-finishing of stainless steel, high-strength steel and cast iron.

Personally, I recommend using the kind of clip-on blade, no grinding, just choose the right blade according to the material it is machined and the allowance.

If the kind of uncoated carbide used;

I don't know if you were wear-resistant or chipping when you used it before;

If you have a broken blade, use YT14, and if you are not wear-resistant, use YW1 to try it.

The car is made of iron, if so, it is recommended that you use an open knife,,, if you can't sharpen, you can buy a knife block with a clamp, but the scabbard is large. YT15 will do.

It should be possible to use YT15, provided that you must make sure that you buy the best cutter head.

Isn't your knife sharpened badly, I've been using YT15 which is quite easy to use.

High-speed steel cutters or cobalt high-speed steel cutters can also be used.

YW1 has good thermal stability, can withstand certain impact loads, and has good versatility. It is suitable for the finishing of difficult-to-machine steels such as heat-resistant steel, high manganese steel, stainless steel, etc., and is also suitable for the finishing of general steel, cast iron and non-ferrous metals. The wear resistance of YW2 is slightly inferior to that of YW1 alloy, but the use strength is higher and can withstand large impact loads.

It is suitable for the finishing and semi-finishing of difficult-to-machine steels such as heat-resistant steel, high manganese steel, stainless steel and high-grade alloy steel, as well as the processing of general steel, cast iron and non-ferrous metals.

To put it simply: YW knife test combination car special material, YW2 is suitable for large amount of YW1 suitable for small amount of [fine turning]. View the original post
