Q: How to adjust the clearance between the upper and lower blades of the slitting machine?: Personally think that the gap of slitting blades is to control the shear gap the upper and lower blades with precision gaskets, if the blade concentricity or balance is not good, is generally re sharpening, if the shaft imbalance gap, recommend the use of grinding device with grinding machine..

Q: When machining M3 worm gear on Y3150 hobbing machine, how to determine the rotation angle and direction of hob cutter head?: Wenling Kaiyuan tool factory to solve; processing turbine is not to turn the angle and direction

Q: Hello everyone！ I would like to ask about the difference between variable displacement hob and non variable hob First of all, is there any difference between the non - variable and modified gears in the design of hobs? If it's different, please give me more details, thank you!: If it is an ordinary standard hob, but also really did not hear the gear hob, nor is it, today I am the first time I heard the name of gear hob change. Of course, if you are grinding hob, repair edge hob, etc., or have customized hob. These non universal hobs, trimming and scraping allowance. The amount of grinding and so on, need to be customized in accordance with the corresponding data. Because these quantities are different

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: M6-12 recommends the use of what their hob grinding, grinding wheel, a grinding method of hob can be good recommendation, currently with 60 of white corundum grinding wheel M12 hob grinding too slowly, a grinding wheel can grind a row of hob a tooth to wear 2-3 hours, but also easy to knife sub fire! Asks God to help solve!!!: Choose 60-70 purpose CBN grinding wheel. Instant coating is not too big a problem

Q: How to judge the direction of hob rotation?: Wait a minute. When the ball is over, call again, just to see where the ball is going.

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: Recently in the shield machine cutter rock breaking simulation, the stress on body feels wrong, ask the shield machine general disc stress on the hob is, what about the magnitude is hundreds of MPa or greater?: Different strata use different types of hobs, and the rock breaking ability is the most natural rock shield machine

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: 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.
