Q:I have not heard of the operation of grinding hob, I would like to ask you, the friend knows, please explain, the more detailed the better, thank you for a friend here.

To use a special hob grinder, first open the power supply, install the hob, can not be used to open a nut tightly - hydraulic hob spindle extends to the hob and grinding wheel center line and then stop motion - wheel hob spindle will fall into the hob flute, to deep point, - Rotary hob, hob front the knife surface attached to the wheel surface, light, rake face and wheel plane is better - tighten the pressure of hob with nuts -- well, can the grinding hob.

Q:The circular cutter mould heating cutting pearl cotton machine, mainly to do with the machine last name? Where can I get it?

Electric heating cutter, round hob, mould, heating, cutting, pearl cotton machine

Q:Why is the front rake hob good for chip removal?

The last said will form a positive front angle, a negative front angle, that is, the two side cutting edges. A closer look at the last post, I found no hob for the main cutting edge discussed. The reason is to answer the question of positive and negative angles. The main rake angle is the front edge of the main cutting edge formed by the intersection of hob diameter and chip groove.

Q:How to adjust the torque of disc hob commonly used in TBM?

Although this problem a long time ago, but still can answer, upstairs are not reliable. The torque of the disc hob is determined by adjusting the inside ring size. General choice of repair, after the experience is easy to handle, according to experience values often meet the requirements.

Q:What is the difference between worm gear hob and gear hob?

The most important thing is: worm gear hob and worm gear meshing with the worm, the outer diameter to be the same, the other tooth shape parameter is needless to say, should be the same!

Q:Does the forum superiors in the gear hobbing process, because the workpiece in addition to generating motion, and an attachment movement for generating helical gear so I want to ask the question is to spur gear hob, turning a lead, the workpiece will rotate (360* / gear hob the number of degrees) for helical gear hob the same rotation of a lead, because of the additional movement of the workpiece, the workpiece rotation degree will be how much? PS: suppose the hob is the same as the gear rotation

The width of the tooth has nothing to do with it. The supply per turn is fixed

Q:What is the number of hob head?

De=DH 2ms type, De-- worm gear, outer diameter DH--, worm throat diameter, ms-- modulus, mechanical design manual, find the outer diameter of about 190 mm

Q:I produce high speed hob, M3, double headed, pressure angle 20 degrees, machined gear Z11 and Z9 gear. The normal line changes momentum 0.06~0.1 and does not dare to shave teeth. I analyze the reasons: long hob processing, less gear, gear inappropriate: in theory inappropriate. The machining tolerance is accumulated; the vibration is large; the accuracy of the hob; the accuracy of the gear hobbing machine. So far, I haven't solved it completely. But I told the gear factory to use the same hob to gear the Z43 gear, which is obviously much better. I hope you can correct me.

Scraping the general process, scraping hob hob - modulation ---- carbide hob scraping. The general amount of stay, such as M5, usually leaves about 0.4. However, alloy hob is more valuable. Scraping hob must have roots, otherwise easily jump alloy hob tooth. Just say that.

Q:What does "hob" mean when cooking?

Correction: hob shall be hob block.Main points of hob block operation:The raw material is hob block roll up into pieces, to cut hob block must grasp three points; one is straight knife, two is the raw material and the knife angle between 45 to 60 degrees (about 70, three dollars is scissors) is every slice have to scroll a raw material, the rolling amplitude is determined you want to process massive size, is generally 1/3 weeks rolling material.Block cutting method of hob:1, a first bevel knife.2. Turn the section face up.3, in the 1/2 section (according to the block size and decided to cut the oblique).4, and then the last section of the plane turned upward.5, or about 1/2 oblique. This keeps turning over everything and turning everything over.

Q:What do you think about the cutting hob?

The thin one becomes thin Mostly uniform, and don't cut it.
