Q:How to adjust the clearance between the upper and lower blades of the slitting machine?

Personally think that the gap of slitting blades is to control the shear gap the upper and lower blades with precision gaskets, if the blade concentricity or balance is not good, is generally re sharpening, if the shaft imbalance gap, recommend the use of grinding device with grinding machine..

Q:Hob mainly used for processing what?

Cut into strips evenly

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:How about the front edge, the normal and the normal tooth shape of the hob with rake angle?

To design hob, first of all, the tooth profile of the reference rack is required, and other related teeth are obtained according to the different structure of the hob. If the hob is a bevel, zero, or rake angle, the reference rack tooth profile can be used as the normal profile of the cutter. If the hob is the straight groove zero front angle, the above reference rack tooth profile shall be converted to the axial profile of the cutter. If the hob is straight groove with positive rake angle, it should be in front of the tooth or the axial profile of basic rack tooth profile conversion to the knife, which is who, detection technology, and the dielectric depends on the designer tool depth and a site. If the hob is a bevel, zero, or front angle, the above reference rack profile shall be converted to the front tooth profile of the knife. While the original basic rack tooth profile and linear tooth shape (involute curve tooth (workpiece) and processing of non involute workpiece) two, the landlord asked not clear answer, ask you to give an example, test analysis.

Q:When machining M3 worm gear on Y3150 hobbing machine, how to determine the rotation angle and direction of hob cutter head?

Pressure angle, vortex data can be calculated, Wenling Kaisheng machinery specialized hob, broach, milling cutter, gear machining

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:I produce high speed hob, M3, double headed, pressure angle 20 degrees, machined gear Z11 and Z9 gear. The normal line changes momentum 0.06~0.1 and does not dare to shave teeth. I analyze the reasons: long hob processing, less gear, gear inappropriate: in theory inappropriate. The machining tolerance is accumulated; the vibration is large; the accuracy of the hob; the accuracy of the gear hobbing machine. So far, I haven't solved it completely. But I told the gear factory to use the same hob to gear the Z43 gear, which is obviously much better. I hope you can correct me.

The number of teeth of the theory is not suitable to duotou hob tooth number, use 9-11 double thread hob, usually duotou hob is to improve work efficiency, and processing precision will be relatively lower is certain, usually will be reflected in the pitch, what equipment you use, and your equipment speed of working table can handle? Personal comments are for reference only

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: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?

Correction: hob shall be hob block.Main points of hob block operation:The raw material is hob block roll up into pieces, to cut hob block must grasp three points; one is straight knife, two is the raw material and the knife angle between 45 to 60 degrees (about 70, three dollars is scissors) is every slice have to scroll a raw material, the rolling amplitude is determined you want to process massive size, is generally 1/3 weeks rolling material.Block cutting method of hob:1, a first bevel knife.2. Turn the section face up.3, in the 1/2 section (according to the block size and decided to cut the oblique).4, and then the last section of the plane turned upward.5, or about 1/2 oblique. This keeps turning over everything and turning everything over.
