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: How to adjust the clearance between the upper and lower blades of the slitting machine?: In the complete slitting knife set, it also includes spacer sleeves, gaskets, and so on. The main purpose is to keep the width between the round blades and the horizontal clearance between the upper and lower blades. The thickness of the common gaskets is between 0.8mm-150mm. Its hardness, regardless of thickness, specifications, are above HRC45 degrees, to prevent scratches, bumps, solid and durable

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!: In the gear hob, the hob design is not the same as the ordinary hob design after the gear parameters are calculated by displacement.

Q: What's the difference in shape and function of the shaper cutter, shaving cutter and gear hob?: There are pictures and documents in the attachment, and the processing methods and principles of each tool are explained

Q: Experts, EG, how much is the hobbing hob used in the actual production of engagement? Feed rate? What is the effect of spindle speed, machining accuracy? What is the M2 M2.5 M3 M3.5 M4 M5 / M6 M7 M8 M9 M10 engagement, the lathe is Chongqing 3180 thank you teachers, generous with your criticism: Feed standard gear is 2.25* modulus relationship of gear spindle speed and machining, Y3180 hobbing machine workbench is the maximum speed of not more than 5 minutes per turn, speed is too fast, the worm attached table soon wear out.

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!!!: Just use CBN's grinding wheel, you can find it on Baidu and hope to help you

Q: Recently, the design of gear hobs and their machining helical gears have been studied! Encountered some problems, I would like to ask for advice! Given the modulus, pressure angle, surface and axial dimensions of gear hob basic parameters such as displacement coefficient which is? There is the use of gear hob to process a bevel gear, the workpiece rotates, a tilt angle of the cutter, moving from top to bottom, is excuse me, the method of helical gear surface machined out of the relationship with the gear hob surface and axial dimensions, is gear hob surface, generating the the method of helical gear surface size?: Because the hobbing process is along the normal direction, so we should know the normal form of the hob. This can be regarded as a rack, and the extension should be normal to the helical gear. But the design is basically not the same. Now computer operations are powerful, all through meshing calculations. The above point of view is for reference only...

Q: What is the number of hob head?: What is a single head hob? What is the number of hob heads: the number of heads (the head number or the number of teeth in the same law)Roll vortex due to vortex with a single head, double head, three head, it should also have the corresponding hob single head, double head, three points, often double or three units lack of hob can only use single head instead, how may be close to the workpiece in drawings is a technology problem.What is the fixed number: the amount of the call is only the quantitative numberIn hobbing adjustment, need to compute three gears, namely indexing hanging round I, feed, hanging wheel i: and differential gear i:. formula i_1=A_1 - Z_1/ (Z+ Z)...... (1) i_2=A_2 & f...... (2) i_3= (n - A_3 (+) /Z_1 (| Delta Z|) + /f (sin beta) / (n - m_n))...... (3) in the formula: A_1 - rolling gear machine indexing set number; A_2 rolled into a given number of gear machine; A_3 hobbing machine differential number; F hob vertical feed amount (mm/r); Z_1 - hob; Z - gear tooth number; Z supplement (micro workpiece tooth number the number of teeth), | Delta Z|

Q: On the Y3150, ready to use left gear hob hobbing left gear. How to adjust machine tools? Thank you, heroes: Left, do not use the knife back, plus the angle of the knife and the angle of the gear

Q: When the gear hobbing machine, gear hobbing cutting depth increases, the cutter shaft transmission box a gala Gala of the strange sound, returned from the new start roll disappears, each gear case, open the inspection found no gear hob shaft breakage, pressure bearing clearance, from the new installation and debugging after the situation remains the same, this is what's the matter?: The pressure has increased
