Q: Hobbing machine hob installation angle is wrong, what will happen?Go to work in the middle of the hob stopped, and then use the manual to hob vertical movement, and then start the workpiece and why card and the card hob is bad? And the consequences?: The helix angle is not rightIn case of a sudden power failure, the insurance operation will withdraw from the workpiece manually and then start to hit the neutral and slow to the stop timeThe gear hobbing machine is a mechanical gear transmission mechanism of a certain gap exists when running to suddenly stop gear internal clearance uneven distribution, and then start the hob cutter tooth workpiece synchronization card bad.

Q: 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

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: 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: 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!!!: Choose 60-70 purpose CBN grinding wheel. Instant coating is not too big a problem

Q: Hob mainly used for processing what?: Gear hob processing external gear; spline hob processing external spline

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?: Because the hobbing process is along the normal direction, so we should know the normal form of the hob. This can be regarded as a rack, and the extension should be normal to the helical gear. But the design is basically not the same. Now computer operations are powerful, all through meshing calculations. The above point of view is for reference only...

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: What is the "hob" knife?: Hob cutting methodOn the left hand material rolling; right hand cut down with the raw material, the cutting knife rotating a cut, to master a certain inclination, cut into the water block, comb back block or hob block shape. Applicable to the quality of crisp food raw materials, such as carrots, potatoes, cucumber and so on.

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?.

With many years' experience in this field, we set up independent R & D center, testing centers, quality control centers inside factory ourselves. We carry out ISO9001 system in the company, all staffs constantly follow advanced managing & strict quality control process, quality-oriented is a constant guidance for our work here.
