Q:What is the number of hob head?
The number or number of teeth in the same law
Q:Din 5480 8j precision involute spline with what grade of hob processing?
Using DIN 5480 8j spline hob precision machining of involute spline, spline hob processing made available but the bottom diameter (darker than DIN 5480, hob) my previous company production of planetary reducer and excavator, frequent contact
Q:Hobbing machine hob shaft strange ring, 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?.
Q:Hob mainly used for processing what?
Gear hob processing external gear; spline hob processing external spline
Q:When machining M3 worm gear on Y3150 hobbing machine, how to determine the rotation angle and direction of hob cutter head?
Wenling Kaiyuan tool factory to solve; processing turbine is not to turn the angle and direction
Q:Why is the front rake hob good for chip removal?
In my understanding, the front corner is the angle formed by the front face and the vertical direction. Thank you for your communication
Q:How to adjust the clearance between the upper and lower blades of the slitting machine?
Method for adjusting installation clearance between upper and lower rolling blades of slitting machine:The clearance between the upper and lower blades of the slitting machine is usually adjusted by precision shims. But be careful, if the blade concentricity or balance is not good, then you have to sharpen the knife again.Slitting machine and slitting line, slitting machine, slitting machine, is a kind of metal cutting equipment. 1. uses: suitable for longitudinal shearing of metal strip, and winding the slitting strip into coils. 2. advantages: easy to operate, high cutting quality, high utilization of materials, cutting speed, stepless speed regulation and so on. 3. structure: from uncoiling (unwinding), material positioning, slitting, slitting, coiling (winding) and so on. 4. applicable materials: tinplate, silicon steel sheet, aluminum strip, copper, stainless steel plate, galvanized sheet, etc.. 5. applicable industries: transformers, motors, household appliances, automobiles, building materials, packaging industry, etc..
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:What is the difference between worm gear hob and gear hob?
There are many forms of worm gear and the parameters of hob are different. The common Archimedes cylindrical worm gear mechanism, the worm gear hob shaft surface tooth shape is the standard modulus, the standard pressure angle (common is 20 degrees), and the gear hob usually is the surface tooth shape as the standard value
Q:What is the reason that the double gear hob changes the gear line of public gear too big?
Scraping the general process, scraping hob hob - modulation ---- carbide hob scraping. The general amount of stay, such as M5, usually leaves about 0.4. However, alloy hob is more valuable. Scraping hob must have roots, otherwise easily jump alloy hob tooth. Just say that.
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.
