During manufacturing of gears on Hob machine, the time taken for the setting of the hob fixture was very high. Whenever a gear of a new Root Diameter is to be manufactured, old fixture has to be removed & the relevant new fixture has to be installed. For changing of the fixture on the gear hob machine the time required was found out

Course Description. Learn and understand fundamentals of gear manufacturing. Acquire knowledge and understanding of gear nomenclature, hob and shaping of spur and helical gears, and splines. Learn and understand hobber and shaper machine set-up, as well as gear tooth element inspection. Understand the manufacturing process before gear tooth

As the hob feeds across the face of the work piece at a fixed depth, gear teeth will gradually be generated by a series of cutting edges, each at a slightly 

Gear-hob machines use a rotating, multiple-tooth cutting tool called a hob for generating teeth on spur gears, worm gears, helical gears, splines, 

For spur gears, set the hob head at the swivel angle as marked. Right hand hob goes one way, left hand the other. What you are trying to achieve is a rack parallel to the face of the gear so a right-hand hob on yours would be tilted to the right, a left-hand hob to the left. Check me on this, sometimes my brain goes astray.

Bring the hob table near the top of your gear blank and bring the blank near the scriber. If possible, before starting the hobber set the RPM to the lowest speed. It may not be possible to adjust the RPM of the hob unless the hobber is running. Now, start the hobber. Do not be surprised if the work table turns rapidly.

1) Incorrect hob sharpening. The hob has been sharpened with negative rake error, making the hob tooth smaller toward the outside diameter with gear tooth larger. This is the opposite of the condition shown in Figure 8. 2) Incorrect swivel angle setting on the hob machine. 3) Bad hob.

Whether compact or large, our gear hob machines impress with their flexibility. They can be used to machine workpieces from 60 millimeters up to oversized 

I've bought a small hob machine which cuts spur gears only. It's a Mikron 112. The machine is complete and working, just needs cleaning and lubricating and a VFD fitted for the motor, I have a full set of change gears and a decent number of cutting hobs.

Hob machines provide gear manufacturers a fast and accurate method for cutting parts. This is because of the generating nature of this particular cutting process. Gear hob is not a form cutting process, such as gashing or milling where the cutter is a conjugate form of the gear tooth.

The new "GE25A," a gear hob machine, will become available with a newly Easy and simple operation software for setting the machining 

Get pricing. Helios offers used hob machines from stock starting at $49,000. These machines are ideal for workpieces up to approximately 7″ OD, and configurations are available that include CNC, mechanical, with automation, and manually loaded. Even used hob machines can be incredibly productive thanks to CNC and automation systems.

In hob spur gear the hob teeth are set parallel to the axis of rotation of the blank. For helical teeth bob , the axis of the hob is set over an angle to produce the proper helix. While worm gears are produced with the axis of the hob set the right angle to the gear blank. Generally two techniques are used in the hob process.

The hob is set up so that the thread of the hob on the side facing the gear blank is directed vertically along the axis. This is done by setting the hob axis at 

Adjust the gear train ratio on the differential section until you get a helix angle between 20 and 30 degrees. Keep adjusting the angle of the hob table until

If a helical gear is to be cut, the hob axis is set at an inclination equal to the sum of the helix angle of the hob and the helix angle of the helical gear. The operation of gear hob involves feeding the revolving hob until it reaches the required depth of the gear tooth.
