Q:The difference between the gear hobbing machine hob hob with single and multi line please tell me what it is: Multi thread hob is long hob, 2 to 3 head, high efficiency, the processing of gear precision is lower. Single track hob is a single head hob, relatively speaking, the processing of gear less efficient, higher processing accuracy.The knife tooth gear cutter for spiral arranged along the cylindrical or conical, used for gear, processing method according to the exhibition of cylindrical worm and other cylindrical workpieces with tooth (see gear, gear). According to the different uses, the hob can be divided into gear hob, worm gear hob, non involute generating hob and fixed hob, etc..

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.: N1Z1=N2Z2, your machine tool is really high-speed machine tools, not only hob can high-speed, and even the workbench is so high speed, running HIGH

Q:How to judge the direction of hob rotation?: Pay attention to the direction of his stroke

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: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:What is the "hob" knife?: Ordinary cylindrical things use thisFor example, use cucumberFirst, at the end of a knife after the material roll chamfer an angle in a way called the beveled knife roller blade.Sorry, I can only find this one

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...

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: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: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!: The design modulus of the shift gear hob is different from the product modulus!
