Q:Grinding wheel for grinding hob
White corundum is not good, we've also used it, the efficiency is low, the old want to repair the wheel, now back to the jade white jade et al than use a lot.
Q:Gear hob surface and shaft surface shape parameter is how to return a responsibility?
The normal dimension of helical gear, if the surface of gear hob is out of gear, is the surface of helical gear involute?
Q:How to judge the direction of hob rotation?
Pay attention to the direction of his stroke
Q:What is the reason that the double gear hob changes the gear line of public gear too big?
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: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: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: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: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: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:How about adjusting the machine tool by using left-hand hob to cut left gear?
Left, do not use the knife back, plus the angle of the knife and the angle of the gear
