Q:How to judge the direction of hob rotation?: The hob is vertical (vertical axis) to see the direction of the spiral direction of the hob blade is raised, most of the hob is rising toward the right, that is, the right-hand hob

Q:Gleason hob material marked as: G30 what material?: The estimate is similar to M35, because there is a higher grade of G70, which is equivalent to powder metallurgy high speed steel! I have seen their material introduction, and now I forgot

Q:Why is the front rake hob good for chip removal?: The rake angle of the front rake is lower than the front angle of the hob, but the inherent error is larger than the zero front angle, so the rough rolling force with low precision is often used

Q:On the Y3150, ready to use left gear hob hobbing left gear. How to adjust machine tools? Thank you, heroes: The angle of the gear subtracts the angle of the knife, the table reverses, and the knife is still turning

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?: Because the hobbing process is along the normal direction, so we should know the normal form of the hob. This can be regarded as a rack, and the extension should be normal to the helical gear. But the design is basically not the same. Now computer operations are powerful, all through meshing calculations. The above point of view is for reference only...

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 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: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 are the main causes of hob breaking?: The workpiece material hardness is high, the tool is not installed properly

Q:I have not heard of the operation of grinding hob, I would like to ask you, the friend knows, please explain, the more detailed the better, thank you for a friend here.: Just the front of the knife Clamping, positioning, special tooling and procedures, see the equipment will understand. When the machine tool is regrinding, after checking, it mainly detects the non radial of the rake face, the accumulative error of the chip groove and the axial deviation of the front cutter surface.
