Q:My company is using hobbing - shaving processing technology, the amount of shaving measurement, cross rod spacing and shaving teeth life size difference of 0.12mm-0.15mmThe accuracy level of the hob is related to the accuracy of the processing gear. The gears we processed require 7 levels of accuracy. The hob before each order is a class a precision, which is in conformity with the standardRecently a group of B level precision hob, no difference in other parameters, not on the bed test work, I would like to consult friends, what will the accuracy grade of hob parameters of gear, like our shaving, shaving is not able to correct these errors?: It has something to do with smoothness! If shaving, the hobbing machine B will be enough! When we do not shave teeth, with double A knife shaving, then the series of knives will not affect too much

Q:The difference between the gear hobbing machine hob hob with single and multi line please tell me what it is: Hob line number is the number of teeth, that is, the relative movement of the tool and the workpiece. Single track hob refers to the hob turn, the workpiece to a tooth. Double line hob refers to the hob turn, the workpiece to two teeth, and so on in turn. The more the number of hob, the higher the machining efficiency.

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:Gleason hob material marked as: G30 what material?: Durability of the tool depends on the tool material and heat treatment hardness, different processing conditions, the selected material is different, the price tool of different materials are not the same, as consumers should have the right to know the Gleason, G30, G50 in terms of customers do not know what material, how to know and price.

Q:Why is the front rake hob good for chip removal?: The rake angle of the front rake is lower than the front angle of the hob, but the inherent error is larger than the zero front angle, so the rough rolling force with low precision is often used

Q:What is the difference between worm gear hob and gear hob?: There are many forms of worm gear and the parameters of hob are different. The common Archimedes cylindrical worm gear mechanism, the worm gear hob shaft surface tooth shape is the standard modulus, the standard pressure angle (common is 20 degrees), and the gear hob usually is the surface tooth shape as the standard value

Q:If a pair of conjugate gears have different coefficients, can the hob be used in general? The addendum of the tooth is required: If the basic parameters of the gear are the same (m * ha * C *), and the tip of the tooth has no trimming, the hob can be used in general. When the addendum of the gear tooth is required, it should be analyzed. If the coefficient of variation between the two coefficients is not large, and the margin of repair is not very strict, there is a general possibility. If the X difference is large, it can not be universal, there will be the top of the tooth repair margin is too small phenomenon. Even when x=0 is rolling with the same knife, the average number of rolls is less, and the gears are smaller at the time of repair, while the number of teeth rolled seems larger.

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: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: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 gear grinder is out of order and the gap is a bit too big
