18 U drill speed feed to give how much suitable material A105 steel

A105 steel I haven't done. Looked at your parameters. Each revolution is fed for.

But there is a number 20 steel to be done at the customer's place.

He made 21 holes. The main problem it encounters is that the chips are constantly chipping. He tried several parameters there, and found that at about every revolution, the chip breaking was relatively good, and the finish of the hole wall.

It's ok too. There is also a way to increase the speed of the machine tool, which can make the parts look brighter.

105 steel is a bit similar to 20 steel, you now cut at a speed of more than 100 meters, in the case of machine tool allowing, good fixture, you can completely raise the meter speed to more than 200 meters, every revolution to give you a try.

The feed is too fast, only 2000 rpm feed is 150, if you want to make the hole smooth, you need to increase the smoothness of the speed of more than 3000 rpm. The smoothness of the U rotation is not good, the smoothness of the rifling knife is good, take the rotation, and then the rifling knife is bore down to ensure smoothness.

Steel normalizing, U drill 4D S2000 F230 four-corner blade, the effect is good, can process 10+ meters, the effect of the triangle blade is not as good as the four-corner.

How much is the rotational speed of drilling a 20-thick stainless steel plate with an 18 U drill on a machining center? What is the feed value?

Drilling stainless steel requires a higher rotational speed and a slower feed belt speed, otherwise it will lead to problems such as rapid wear of the cutting edge, difficulty dropping chips or clogging of the drill bit. The specific parameters should be determined according to the specific drill bit model, steel type, processing conditions, etc., the following is the general reference value: speed:

Generally between 2000-3000 rpm, it can be fine-tuned according to different drill bit models and steel hardness. Feed speed: generally between millimeter revolutions, it can also be fine-tuned according to the specific situation.

It is important to note that drill bits are susceptible to heat when machining stainless steel, so they need to be cooled sufficiently, which can be done with specialized cutting fluids or water. In addition, it is necessary to pay attention to the stability of the collapse line during the cutting process to avoid excessive impact or lateral force of the drill bit in the machining.

Hello dear, glad to answer for you. The 15U drill speed feed parameter is 45 knives. The speed feed of the U-drill is a form of showing the speed of the U-shaped drill bit.

Recommendations 5000-10000) Recommendations 2000-3000) Recommendations 2000) Recommendations 2000) Recommendations 1200) 3-4 (Recommendations 800+) 5-9 (Recommendations 600-800) 10-14 (Recommendations 600) 15-18 (Recommendations 320-400) 24-30 (Recommendations 240-270) This implicit speed is for reference only. In practice, the required drilling speed and feed rate should be finalized based on the drilling depth and material.

Summary. No. 45 steel drilling (no heat treatment) in the case of low hardness of the material; Drilling 4-8mm holes can be selected from 1000-1200 rpm. Drill 10-14 mm holes at a speed of 500-700 rpm.

When the hardness of the material is HRC23-34, the rotation speed and feed speed should also be reduced when drilling the hole, and the cooling water should be used to cool down more to reduce the cutting heat.

Drill 12 through holes in the radial drill, made of 45 steel, how much is the appropriate speed feed?

No. 45 steel drilling (no heat treatment) in the case of low hardness of the material; Drill 4-8 mm holes in 1000-1200 rpm. Drill 10-14 mm holes at a speed of 500-700 rpm. When the hardness of the material is HRC23-34, the rotation speed and feed speed should also be reduced when drilling the stool Zheng hole, and cooling water should be used to cool down more to reduce the cutting heat.

If the 45 steel is annealed, the speed can be beaten to 800 rpm. The amount of the pass is about that. However, when drilling, Nai Sakura sells to take out the drill bit several times to clean up the drill cuttings, and prevent the drill bit from being squeezed to death by the drill cuttings and breaking.

In addition, apply lubricant or oil to the drill bit.

Without heat treatment, I rotate at 400 and feed, is it too slow?

Hello dear! Your revs of 400 are a bit slow, you can try to add a little more.

Another problem is that as soon as the speed is high, the quality of the hole will be very poor, and there are potholes inside, is the drill bit not sharpened well or what is the reason?

1.The quality of the drill bit is not stupid 2The speed of the electric drill is not enough 3When punching, the water did not keep up with the drill and burned 4Drill the drill bit on the oil stone (fine whetstone) with judgment === We call it milling drill bit.

The drill speed and feed are calculated as follows: 1. S 1000 V (D)S Spindle speed V m min (cutting speed) Tool diameter 2, f s ff=mm min (feed speed) S spindle speed f The materials processed by drills with different diameters per revolution feed are different, and the speed and feed are very different. D10 white steel drill bit, processing 45 rigid, s=800, f=100 in the same case, the larger the diameter, the lower the speed.

In practice, appropriate adjustments are made according to the chip condition and cutting load. Eliminate centering errors when any drill bit is working, and the first few turns are critical. Because at the beginning of cutting, the drill head is subjected to eccentric forces.

In addition, the irregular shape of the workpiece surface can cause lateral slips, causing the tool to bend, break, or at least increase the deviation of the hole. For drill bits with a diameter of less than 3mm, Mitsubishi recommends that an initial hole with a depth of 1 2 times the diameter of Zhen Jianfeng be drilled with a rigid centering drill. The tip angle of the centering drill should be equal to or greater than the tip angle of the final drill hole.

If the top angle of the centering drill is small, the two cutting edges will contact the workpiece first than the center when the micro drill is cut in, which is easy to cause chipping.
