Q:My company is using hobbing - shaving processing technology, the amount of shaving measurement, cross rod spacing and shaving teeth life size difference of 0.12mm-0.15mmThe accuracy level of the hob is related to the accuracy of the processing gear. The gears we processed require 7 levels of accuracy. The hob before each order is a class a precision, which is in conformity with the standardRecently a group of B level precision hob, no difference in other parameters, not on the bed test work, I would like to consult friends, what will the accuracy grade of hob parameters of gear, like our shaving, shaving is not able to correct these errors?: Class a hob and B grade hob as you have the final shaving process hobbing to use, both can, technically, economically speaking, B is more reasonable. If the hobbing process is finished, it should be A or AA. The tooth profile error of gear hobbing process mainly originates from the precision, accuracy, hob cutter hob and gear blank datum correction, and hobbing process accuracy, tooth pitch accumulated mainly depends on the precision of hobbing machine precision and gear blank correction accuracy. Hob different levels of error in the 0.05MM level, so instead of using B hob, shaving allowance as far as possible to stay, that is, 0.15MM can. Pay attention to the roughness of the gear surface as it was before.

Q: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.

Q:I produce high speed hob, M3, double headed, pressure angle 20 degrees, machined gear Z11 and Z9 gear. The normal line changes momentum 0.06~0.1 and does not dare to shave teeth. I analyze the reasons: long hob processing, less gear, gear inappropriate: in theory inappropriate. The machining tolerance is accumulated; the vibration is large; the accuracy of the hob; the accuracy of the gear hobbing machine. So far, I haven't solved it completely. But I told the gear factory to use the same hob to gear the Z43 gear, which is obviously much better. I hope you can correct me.: The accuracy of the rotary table of the gear hobbing machine is large, or the deviation of the concentricity between the small column head and the worktable is too large. The first step is to check the gear hobbing machine workbench precision spindle work station is equipped with a standard, do not try to play the top hat, mandrel, preferably with micrometer, if the mandrel in the beating of a point always hit the minimum (minimum can reach 0.003), always in 0.015~0.03 between swing dancing. Sometimes more than 0.03, the surface of the worktable shell and the surface of the cone must be overhauled. If the core shaft can be positive, it is on the top of the top, a core shaft on the two beat, normal upper and lower deviation but over 0.015, such as the top is not so, that column with the table concentricity deviation is too large, to correct the small column. That is, double headed cutter processing, less gear, gear, public wire, there is momentum, but there is no landlord said so big ah. No more than 0.03. It is also important to check the accuracy of hobbing machines and gear blanks.

Q:How to judge the direction of hob rotation?: Pay attention to the direction of his stroke

Q:Recently, the design of gear hobs and their machining helical gears have been studied! Encountered some problems, I would like to ask for advice! Given the modulus, pressure angle, surface and axial dimensions of gear hob basic parameters such as displacement coefficient which is? There is the use of gear hob to process a bevel gear, the workpiece rotates, a tilt angle of the cutter, moving from top to bottom, is excuse me, the method of helical gear surface machined out of the relationship with the gear hob surface and axial dimensions, is gear hob surface, generating the the method of helical gear surface size?: 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:M6-12 recommends the use of what their hob grinding, grinding wheel, a grinding method of hob can be good recommendation, currently with 60 of white corundum grinding wheel M12 hob grinding too slowly, a grinding wheel can grind a row of hob a tooth to wear 2-3 hours, but also easy to knife sub fire! Asks God to help solve!!!: You can choose PA or SA grinding wheel, particle size 46-60#, hardness J-K, you can.

Q:Hob mainly used for processing what?: Cut into strips evenly

Q:How to adjust the torque of disc hob commonly used in TBM?: The jack is adjusted by means of a jack mounted in different parts

Q:The circular cutter mould heating cutting pearl cotton machine, mainly to do with the machine last name? Where can I get it?: I have seen this kind of equipment as fast as possible, and the product is as fast as running water

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.
