1. The app on the palm is a liar. He can't log in any more. He cooperates with pinoo and runs away with money. I was cheated into investing 500 yuan in mining machinery.

2. The best real name authentication software do not easily register, may leak your information, as you said I did not use, do not know.

3. I'm afraid these things can't be quantified, and I think it's better not to toss these things.

4. You can find Blizzard mining machine, reasonable cost, high mining efficiency, high configuration, optional

5. There's no ranking list... It's just for you to push your own... Xintong's seems to be OK, and there's a small manufacturer, Qingzhou Fangyuan, which is better used by friends nearby. Xiangyang and Qingzhou are both big procers of slag raking machines, but the quality is uneven. Be careful with re-election.

Lathe: linear speed = 3.14 * workpiece diameter * rotational speed (s), feed rate per minute f = feed rate per revolution * rotational speed s, milling machine: linear speed of blade = 3.14 * nominal diameter of tool * rotational speed of spindle s, feed rate per minute f = feed rate per tooth * number of teeth * rotational speed of spindle (n), unit meter and millimeter should be accurate

The selection of cutting speed is based on the cutting rate, feed rate and tool life. Improving the cutting speed is also a measure to improve proctivity. According to the proction time experience, it can also be selected by looking up the table within the cutting speed range allowed in the machine tool manual or referring to the relevant cutting data manual. After the cutting speed is determined, the cutting speed can be adjusted as n = 1000vc/ π D calculate the spindle speed of the machine tool

extended data:

in traditional machining, the feed speed is limited by the cutting speed and the rigidity of the process system, and the value is generally small; But in the high-speed machining mode, because of the increase of cutting speed, the cutting force and cutting heat are reced, which makes it possible to choose a larger feed speed when machining small resial materials

At the same time, larger feed speed can also effectively prevent the workpiece surface and tool burn, chip build-up and work hardening caused by high cutting speed

for example, when the ball end mill with a diameter of 10 mm TiAlN coating material is used to process the pre hardened steel with a hardness of 40 HRC, when the spindle speed reaches 12 000 R / min, the feed speed can be as high as 2 500 mm / min. In some cases where the tool diameter is smaller and the spindle speed is higher, the feed speed can be higher. However, the higher the feed rate, the better, because too high feed rate will make the surface quality of the workpiece decline

Speed multiplied by feed per revolution = feed per minute
500 * 0.3 = 150 feed per minute

feed per minute divided by speed = feed per revolution
150 / 500 = 0.3 feed per revolution × F

VF = feed speed (mm / min)

n = RPM (spindle revolutions)

F = cutting feed (mm / Rev)

cutting linear speed calculation formula: v= π Dn / 1000

n = RPM (spindle speed)

d = ￠ mm (cutting diameter)

V = m / min

V = m / min π= 3.14

feed - the greater the feed, the greater the roughness, the higher the feed, the higher the machining efficiency, and the smaller the tool wear. Therefore, the feed is generally determined, and the feed is determined according to the required roughness

extended data:

factors determining feed rate and cutting feed rate:

1. Tool material. The maximum allowable cutting speed varies with the tool material. The high temperature cutting speed of high speed steel tool is less than 50m / min, carbide tool is more than 100m / min, and ceramic tool is up to 1000m / min

2. The hardness of the workpiece material will affect the cutting speed of the tool. The cutting speed of the same tool should be reced when machining hard materials, but it can be increased when machining soft materials

3. Tool life. If the tool life is required to be long, a lower cutting speed should be adopted. On the contrary, higher cutting speed can be used

4, cutting depth and feed. When the cutting depth and feed are large, the cutting resistance is also large, and the cutting heat will increase, so the cutting speed should be reced

5. Tool shape. The shape of the tool, the size of the angle, the sharpness of the edge will affect the selection of cutting speed

6. Use of coolant. The machine tool has good rigidity and high precision, which can improve the cutting speed; On the contrary, the cutting speed should be reced

The processing sequence generally follows the following principles:

1. According to the order of rough turning, semi finish turning and finish turning, the machining accuracy is graally improved

2. The parts close to the tool setting point are processed first, and the parts far away from the tool setting point are processed later, so as to shorten the tool moving distance and rece the idle travel time

3. For parts with both inner and outer surfaces to be machined, rough machining of inner and outer surfaces should be carried out first, and then finish machining of inner and outer surfaces

4. The surface used as precision reference should be processed first. The more accurate the surface of positioning reference is, the smaller the clamping error is

The formula of feed rate and cutting feed is
VF = n × F
