FAQ

The difference between the gear hobbing machine hob hob with single and multi line please tell me what it is
Hob line number is the number of teeth, that is, the relative movement of the tool and the workpiece. Single track hob refers to the hob turn, the workpiece to a tooth. Double line hob refers to the hob turn, the workpiece to two teeth, and so on in turn. The more the number of hob, the higher the machining efficiency.
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.
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
How about the front edge, the normal and the normal tooth shape of the hob with rake angle?
Generally speaking, the front rake or the negative rake of the hob, the slot is straight. If the spiral groove hob, then the front face of the eccentric distance can not be controlled, the front and left side of the tooth shape can not be measured using the front face of the intuitive measurement method, there will be no knife surface measurement method is inevitable. If you really need, you can use the following formula Tan = w (Tan an*cos af+-sin AF *sin WF /cos WF) this formula can be converted into the reference tooth angle parameters of front blade tooth angle formula in meaning, can I see the previously available analytical formula
Grinding wheel for grinding hob
LZ uses the five axis linkage tool grinding, the good machine tool certainly must match the good tool! The grinding wheel should be CBN, with a particle size of 100-120.
Does the forum superiors in the gear hobbing process, because the workpiece in addition to generating motion, and an attachment movement for generating helical gear so I want to ask the question is to spur gear hob, turning a lead, the workpiece will rotate (360* / gear hob the number of degrees) for helical gear hob the same rotation of a lead, because of the additional movement of the workpiece, the workpiece rotation degree will be how much? PS: suppose the hob is the same as the gear rotation
The width of the tooth has nothing to do with it. The supply per turn is fixed
On the Y3150, ready to use left gear hob hobbing left gear. How to adjust machine tools? Thank you, heroes
Not this meaning, specific point, and, the left and right knife processing, the gear hobbing machine work table whether to reverse, if reversed, the knife pole is also reversed, need to put the turret back loaded?...... Ask for expert advice...
Recently in the shield machine cutter rock breaking simulation, the stress on body feels wrong, ask the shield machine general disc stress on the hob is, what about the magnitude is hundreds of MPa or greater?
30MPa, the answer is complete.
