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
All kinds of modulus gear feed is not the same, generally the first knife is bigger, the back a few small knife. But some have a knife to survive.
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.
When hobbing, the feed amount is related to the precision of the gear. In order to achieve high precision, the scoring is coarse, fine, rolling and cutting. Generally speaking, within two 5mm modulus, the gears with seven to eight orders can be made according to the requirements of the drawing. In the market economy, if it is a one-sided pursuit of efficiency and quality can be relaxed if I have seen 8mm modulus gear knife into place, cutting tool and machine tool (Y3180A hobbing machine) can not stand, can the boss agree that it must be so. This kind of dry work check, do not check, you can certainly say that the quality of substandard, diameter jump failure, the roughness of the surface roughness, tooth shape and tooth direction, not to mention unqualified. But the boss is proud that the product can be sold at a low price, in short supply. At the technical level, I could only accept such a process, so I resigned.
