- Q:Grinding wheel for grinding hob
- A plain white disc grinding wheel should be fine. Basically, the wheels are standard parts
- Q:Hobbing machine hob shaft strange ring, what's the matter?
- This situation is generally caused by heavy load, please focus on the following conditions:1, the transmission shaft transmission less oil, to be added. 2, hob wear a large amount, or hob grinding is not correct, causing chip power increases, sharpening. 3, eat too much, over load rolling gear machine, adjust the cutting depth to the right. 4, whether the hardness of the workpiece material is too high?.
- Q:How to judge the direction of hob rotation?
- Pay attention to the direction of his stroke
- Q:What are the main causes of hob breaking?
- In my opinion, there are many reasons for the broken teeth of the hob. In addition to the above analysis, it is also related to the regrinding of the tool, such as grinding the front face of the knife and grinding cracks
- 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
- Q:The influence of hob accuracy grade on gear machining
- 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:Hob mainly used for processing what?
- Ordinary monolithic hob can cut the pizza, a high precision hob can cut softer materials such as rubber, patchwork, cutting. Mechanical hob is used in lathe processing, the type is not clear.
- 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:How about adjusting the machine tool by using left-hand hob to cut left gear?
- The angle of the gear subtracts the angle of the knife, the table reverses, and the knife is still turning
- 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....
