FAQ

What's the difference in shape and function of the shaper cutter, shaving cutter and gear hob?
Slotting cutters are cutters used on slotting machines, which mainly process internal and external gears. The hobbing cutter is a tool for processing gears on a gear hobbing machine. It can process gears other than internal gears. The shaving cutter is a cutting tool for shaving gears on a shaving machine, mainly finishing the gears. Structurally different
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
Gleason hob material marked as: G30 what material?
Tool design post ASP 2030 is closer to S590
What is the difference between worm gear hob and gear hob?
There are many forms of worm gear and the parameters of hob are different. The common Archimedes cylindrical worm gear mechanism, the worm gear hob shaft surface tooth shape is the standard modulus, the standard pressure angle (common is 20 degrees), and the gear hob usually is the surface tooth shape as the standard value
What are the main causes of hob breaking?
In my opinion, there are many reasons for the broken teeth of the hob. In addition to the above analysis, it is also related to the regrinding of the tool, such as grinding the front face of the knife and grinding cracks
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.
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
This has something to do with your axial feed speed. It should be the angle increase of the straight gear (360 degrees / gear lead) * feed speed
Experts, EG, how much is the hobbing hob used in the actual production of engagement? Feed rate? What is the effect of spindle speed, machining accuracy? What is the M2 M2.5 M3 M3.5 M4 M5 / M6 M7 M8 M9 M10 engagement, the lathe is Chongqing 3180 thank you teachers, generous with your criticism
Feed standard gear is 2.25* modulus relationship of gear spindle speed and machining, Y3180 hobbing machine workbench is the maximum speed of not more than 5 minutes per turn, speed is too fast, the worm attached table soon wear out.
