Q:The difference between the gear hobbing machine hob hob with single and multi line please tell me what it is

This is actually very simple as long thread form almost but the gear ratio will turn to recommend a specific group of host is the expertise of 124669105 mechanical processing technology alliance

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

Electric knife, but you said hob all heating, I really don't know. Should be generally punch processing. There are also hot knife processing, but not hob. A cold knife can also heat it. Cold hob heating, you can try....

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?

Class a hob and B grade hob as you have the final shaving process hobbing to use, both can, technically, economically speaking, B is more reasonable. If the hobbing process is finished, it should be A or AA. The tooth profile error of gear hobbing process mainly originates from the precision, accuracy, hob cutter hob and gear blank datum correction, and hobbing process accuracy, tooth pitch accumulated mainly depends on the precision of hobbing machine precision and gear blank correction accuracy. Hob different levels of error in the 0.05MM level, so instead of using B hob, shaving allowance as far as possible to stay, that is, 0.15MM can. Pay attention to the roughness of the gear surface as it was before.

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?

To answer the first question of cross-section of a thread, is the shape and size of the axial section profile shaft open when the bus is also in this section marked normal profile refers to open along with the thread section perpendicular to the direction of the normal section size is in the size of this section for the second the problem, really is a little big, clear need space more, therefore, suggest that you download a book at the Forum (gear cutter design) the book look, on page 35 is down

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:Gleason hob material marked as: G30 what material?

Gleason mark tool materials are: REX45, REX54 general REX76, G30, G50 but the same tool, G30 tool label tagging REX54 price than the price is much lower, and the M35 tool almost, so I suspect that this material is M35

Q:Hobbing machine hob installation angle is wrong, what will happen?Go to work in the middle of the hob stopped, and then use the manual to hob vertical movement, and then start the workpiece and why card and the card hob is bad? And the consequences?

For the share, I'll tell you. The angle is shifted, the hob's pitch is wrong. The back angle is also easy to take off.. If you move back, you'll certainly get stuck. With hob is also a certain relationship. Wenling Kaiyuan tool factory this kind of strength brand hob generally won't card bad. Don't forget to give me a bonus!!!!

Q:If a pair of conjugate gears have different coefficients, can the hob be used in general? The addendum of the tooth is required

We know that a pair of angle changing gears with unequal coefficient of change is not equal to 0, and his teeth are of different height. However, the tool edge is in accordance with the hob to pitch circle root circle direction follow certain dimensions of manufacturing tool edge starting point, and the gear tooth height because the modification coefficient is not the same as the height difference, top gear and gear tooth tangent, and this kind of hob is. The gear tooth top to the edge starting point is fixed, then the gear is cut after the addendum modification on the size difference is too much, so the hob is not universal

Q:Known gear hobbing machine speed, knife, and hob modulus, the number of teeth of the workpiece, the processing thickness (Chi Kuan), how to calculate the processing hours?

A knife or two knives, stroke shaft speed to the number (small feed rate can be slower), how much processing height, very good ah!

Q:On the Y3150, ready to use left gear hob hobbing left gear. How to adjust machine tools? Thank you, heroes

Not this meaning, specific point, and, the left and right knife processing, the gear hobbing machine work table whether to reverse, if reversed, the knife pole is also reversed, need to put the turret back loaded?...... Ask for expert advice...
