Q:What's the difference in shape and function of the shaper cutter, shaving cutter and gear hob?

The shaper cutter is like a straight gear, and the front face of the cutter is concave taper in order to form the rake angle, and the machining accuracy of the gear is higher (than hobbing).The shaving cutter is like a helical gear, and the cutter teeth are arranged in a longitudinal groove, which is used for fine machining after slotting and hobbing.The hobbing cutter is shaped like a worm and is arranged along the axial direction, and belongs to the rack type gear cutter.

Q:Din 5480 8j precision involute spline with what grade of hob processing?

Using DIN 5480 8j spline hob precision machining of involute spline, spline hob processing made available but the bottom diameter (darker than DIN 5480, hob) my previous company production of planetary reducer and excavator, frequent contact

Q:What is the "hob" knife?

Hob: common knife, generally used for cutting brittle materials and the type of raw materials.From the end of the material into 45 degrees angle vertical vertical knife. Then turn the material to the body direction, according to the number of rotating material to determine the size of the dishes

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?

The normal dimension of helical gear, if the surface of gear hob is out of gear, is the surface of helical gear involute?

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:If a pair of conjugate gears have different coefficients, can the hob be used in general? The addendum of the tooth is required

We know that a pair of angle changing gears with unequal coefficient of change is not equal to 0, and his teeth are of different height. However, the tool edge is in accordance with the hob to pitch circle root circle direction follow certain dimensions of manufacturing tool edge starting point, and the gear tooth height because the modification coefficient is not the same as the height difference, top gear and gear tooth tangent, and this kind of hob is. The gear tooth top to the edge starting point is fixed, then the gear is cut after the addendum modification on the size difference is too much, so the hob is not universal

Q:How to judge the direction of hob rotation?

Pay attention to the direction of his stroke

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!!!

You can choose PA or SA grinding wheel, particle size 46-60#, hardness J-K, you can.

Q:What does "hob" mean when cooking?

The name of the hob block, not food, and irregular lumps, as long as the eggplant, cut the eggplant, cut, turn, turn, is the hob block

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
