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: Din 5480 8j precision involute spline with what grade of hob processing?: Yes, I think your company is the product of the whole machine, and if it is the processing of outsourcing, we must communicate with customers

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: When hobbing, the feed amount is related to the precision of the gear. In order to achieve high precision, the scoring is coarse, fine, rolling and cutting. Generally speaking, within two 5mm modulus, the gears with seven to eight orders can be made according to the requirements of the drawing. In the market economy, if it is a one-sided pursuit of efficiency and quality can be relaxed if I have seen 8mm modulus gear knife into place, cutting tool and machine tool (Y3180A hobbing machine) can not stand, can the boss agree that it must be so. This kind of dry work check, do not check, you can certainly say that the quality of substandard, diameter jump failure, the roughness of the surface roughness, tooth shape and tooth direction, not to mention unqualified. But the boss is proud that the product can be sold at a low price, in short supply. At the technical level, I could only accept such a process, so I resigned.

Q: Hob mainly used for processing what?: Gear hob processing external gear; spline hob processing external spline

Q: What do you think about the cutting hob?: Hob used for cutting, cutting out the shape of different blocks, similar volume, mainly used for Pier dishes to increase the shape of sensory effects, home braised beef / braised meat and other auxiliary materials, generally use this knife workCut hob basic attention is: cut a knife, rotating material 30-45 degrees, so that the cut out of different shapes, similar volume, to match the main ingredients

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: Gleason hob material marked as: G30 what material?: The estimate is similar to M35, because there is a higher grade of G70, which is equivalent to powder metallurgy high speed steel! I have seen their material introduction, and now I forgot

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

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.
