- 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:What is the number of hob head?
- The number or number of teeth in the same law
- Q:Gear hob surface and shaft surface shape parameter is how to return a responsibility?
- To answer the first question of cross-section of a thread, is the shape and size of the axial section profile shaft open when the bus is also in this section marked normal profile refers to open along with the thread section perpendicular to the direction of the normal section size is in the size of this section for the second the problem, really is a little big, clear need space more, therefore, suggest that you download a book at the Forum (gear cutter design) the book look, on page 35 is down
- Q:Gleason hob material marked as: G30 what material?
- Tool design post ASP 2030 is closer to S590
- Q:Hobbing machine hob installation angle is wrong, what will happen?Go to work in the middle of the hob stopped, and then use the manual to hob vertical movement, and then start the workpiece and why card and the card hob is bad? And the consequences?
- The general accuracy, generally a twice fine, roll into half in the dynamic angle (angle between the roll angle transform, gear hob axis and a position transform) cutter and gear blank is not the tooth socket overlap, serious breakage, the workpiece is not serious waste.
- 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: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: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:Tool presetting method in hob grinding
- To use a special hob grinder, first open the power supply, install the hob, can not be used to open a nut tightly - hydraulic hob spindle extends to the hob and grinding wheel center line and then stop motion - wheel hob spindle will fall into the hob flute, to deep point, - Rotary hob, hob front the knife surface attached to the wheel surface, light, rake face and wheel plane is better - tighten the pressure of hob with nuts -- well, can the grinding hob.
- Q:Known gear hobbing machine speed, knife, and hob modulus, the number of teeth of the workpiece, the processing thickness (Chi Kuan), how to calculate the processing hours?
- A knife or two knives, stroke shaft speed to the number (small feed rate can be slower), how much processing height, very good ah!
