Q:Din 5480 8j precision involute spline with what grade of hob processing?: Yes, I think your company is the product of the whole machine, and if it is the processing of outsourcing, we must communicate with customers

Q: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.

Q:Grinding wheel for grinding hob: White corundum is not good, we've also used it, the efficiency is low, the old want to repair the wheel, now back to the jade white jade et al than use a lot.

Q: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.

Q: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.

Q:How to adjust the torque of disc hob commonly used in TBM?: Although this problem a long time ago, but still can answer, upstairs are not reliable. The torque of the disc hob is determined by adjusting the inside ring size. General choice of repair, after the experience is easy to handle, according to experience values often meet the requirements.

Q:The circular cutter mould heating cutting pearl cotton machine, mainly to do with the machine last name? Where can I get it?: Electric knife, but you said hob all heating, I really don't know. Should be generally punch processing. There are also hot knife processing, but not hob. A cold knife can also heat it. Cold hob heating, you can try....

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.

Q: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.

Q:When the gear hobbing machine, gear hobbing cutting depth increases, the cutter shaft transmission box a gala Gala of the strange sound, returned from the new start roll disappears, each gear case, open the inspection found no gear hob shaft breakage, pressure bearing clearance, from the new installation and debugging after the situation remains the same, this is what's the matter?: This situation is generally caused by heavy load, please focus on the following conditions:1, the transmission shaft transmission less oil, to be added. 2, hob wear a large amount, or hob grinding is not correct, causing chip power increases, sharpening. 3, eat too much, over load rolling gear machine, adjust the cutting depth to the right. 4, whether the hardness of the workpiece material is too high?.
