FAQ

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?

The higher the accuracy, the smaller the gear tolerances, the better the surface finish. But you want to see carefully, and write is B class, sometimes can not reach the B level requirements, and only test to know whether it is B level, so must buy big manufacturers of goods

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 number of teeth of the theory is not suitable to duotou hob tooth number, use 9-11 double thread hob, usually duotou hob is to improve work efficiency, and processing precision will be relatively lower is certain, usually will be reflected in the pitch, what equipment you use, and your equipment speed of working table can handle? Personal comments are for reference only

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.

How to adjust the clearance between the upper and lower blades of the slitting machine?

In the complete slitting knife set, it also includes spacer sleeves, gaskets, and so on. The main purpose is to keep the width between the round blades and the horizontal clearance between the upper and lower blades. The thickness of the common gaskets is between 0.8mm-150mm. Its hardness, regardless of thickness, specifications, are above HRC45 degrees, to prevent scratches, bumps, solid and durable

Gleason hob material marked as: G30 what material?

Durability of the tool depends on the tool material and heat treatment hardness, different processing conditions, the selected material is different, the price tool of different materials are not the same, as consumers should have the right to know the Gleason, G30, G50 in terms of customers do not know what material, how to know and price.

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.

To use a special hob grinder, first open the power supply, install the hob, can not be used to open a nut tightly - hydraulic hob spindle extends to the hob and grinding wheel center line and then stop motion - wheel hob spindle will fall into the hob flute, to deep point, - Rotary hob, hob front the knife surface attached to the wheel surface, light, rake face and wheel plane is better - tighten the pressure of hob with nuts -- well, can the grinding hob.

Hello everyone！ I would like to ask about the difference between variable displacement hob and non variable hob First of all, is there any difference between the non - variable and modified gears in the design of hobs? If it's different, please give me more details, thank you!

The design modulus of the shift gear hob is different from the product modulus!

What does "hob" mean when cooking?

Say. You get with carrots. The first knife across a cut. The formation of an oblique incision. Then the carrots rotated 60 degrees. With this cut.
