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: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?: The helix angle is not rightIn case of a sudden power failure, the insurance operation will withdraw from the workpiece manually and then start to hit the neutral and slow to the stop timeThe gear hobbing machine is a mechanical gear transmission mechanism of a certain gap exists when running to suddenly stop gear internal clearance uneven distribution, and then start the hob cutter tooth workpiece synchronization card bad.

Q:Gleason hob material marked as: G30 what material?: Tool design post ASP 2030 is closer to S590

Q:What is the "hob" knife?: Hob cutting methodOn the left hand material rolling; right hand cut down with the raw material, the cutting knife rotating a cut, to master a certain inclination, cut into the water block, comb back block or hob block shape. Applicable to the quality of crisp food raw materials, such as carrots, potatoes, cucumber and so on.

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:What is the number of hob head?: De=DH 2ms type, De-- worm gear, outer diameter DH--, worm throat diameter, ms-- modulus, mechanical design manual, find the outer diameter of about 190 mm

Q:Does the forum superiors in the gear hobbing process, because the workpiece in addition to generating motion, and an attachment movement for generating helical gear so I want to ask the question is to spur gear hob, turning a lead, the workpiece will rotate (360* / gear hob the number of degrees) for helical gear hob the same rotation of a lead, because of the additional movement of the workpiece, the workpiece rotation degree will be how much? PS: suppose the hob is the same as the gear rotation: This has something to do with your axial feed speed. It should be the angle increase of the straight gear (360 degrees / gear lead) * feed speed

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!

Q:How about the front edge, the normal and the normal tooth shape of the hob with rake angle?: Generally speaking, the front rake or the negative rake of the hob, the slot is straight. If the spiral groove hob, then the front face of the eccentric distance can not be controlled, the front and left side of the tooth shape can not be measured using the front face of the intuitive measurement method, there will be no knife surface measurement method is inevitable. If you really need, you can use the following formula Tan = w (Tan an*cos af+-sin AF *sin WF /cos WF) this formula can be converted into the reference tooth angle parameters of front blade tooth angle formula in meaning, can I see the previously available analytical formula

Q:When machining M3 worm gear on Y3150 hobbing machine, how to determine the rotation angle and direction of hob cutter head?: Wenling Kaiyuan tool factory to solve; processing turbine is not to turn the angle and direction
