- Q:What grinding wheel do we use to grind HSS HSS hobs?
- You can choose PA or SA grinding wheel, particle size 46-60#, hardness J-K, you can.
- Q:What are the main causes of hob breaking?
- In my opinion, there are many reasons for the broken teeth of the hob. In addition to the above analysis, it is also related to the regrinding of the tool, such as grinding the front face of the knife and grinding cracks
- Q:Hobbing machine hob shaft strange ring, what's the matter?
- The gear grinder is out of order and the gap is a bit too big
- Q:How about adjusting the machine tool by using left-hand hob to cut left gear?
- Left, do not use the knife back, plus the angle of the knife and the angle of the gear
- 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:Help: bevel gear hobbing processing workpiece and hob speed relationship
- 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:How to adjust the torque of disc hob commonly used in TBM?
- Torque wrenches need to be used, the specific firstname.lastname@example.org
- 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:How about the front edge, the normal and the normal tooth shape of the hob with rake angle?
- Generally speaking, the front rake or the negative rake of the hob, the slot is straight. If the spiral groove hob, then the front face of the eccentric distance can not be controlled, the front and left side of the tooth shape can not be measured using the front face of the intuitive measurement method, there will be no knife surface measurement method is inevitable. If you really need, you can use the following formula Tan = w (Tan an*cos af+-sin AF *sin WF /cos WF) this formula can be converted into the reference tooth angle parameters of front blade tooth angle formula in meaning, can I see the previously available analytical formula
- Q:When machining M3 worm gear on Y3150 hobbing machine, how to determine the rotation angle and direction of hob cutter head?
- When using worm gear hob, the tool holder is zero to zero. Sub gear: clutch to the straight gear processing position, differential open, hang 36 teeth fixed number wheel, but with fixed number wheel 24 than worm gear teeth number to calculate the number of 4 teeth.
