2007年5月18日 · Unless your Hass has a very fine resolution spindle encoder ( which I doubt is even an offered option on any Haas) this will not be possible. Any slight variation in timing between between the two spindles will produce tooth spacing and lead errors that you most likely won't want in your parts.

The Gear Hobbing unit offers high stiffness and runout accuracy. High flexibility due to interchangeable milling arbors for different cutting tools. Interchangeable milling arbor – removable counter support. Synchronization of work piece and …

2008年12月6日 · I have a Haas VF2 with a trunnion and yesterday a friend asked me if I could match the spindle and B-axis rpms well enough for gear hobbing. What he envisioned is tilting the A-axis to 90 degrees, set the appropriate spindle and B-axis rpms and feed over with a hob in the spindle to hob the gears.

2024年7月16日 · Master CNC gear hobbing with a fourth axis in this easy-to-follow guide! Learn gear design, calculations, and enhance your machining skills today.

2007年12月4日 · Gear hobbing can be done on many CNC lathes with live tooling IF the machine has certain control features. When I worked for Doosan, we routinely did this in the showroom.

2007年5月18日 · You'd need a gcode for the Haas to synchronize the spindle to the A axis. While we've got sync between the spindle and the Z for rigid tapping, I don't know if any other options exist. I've seen videos of hobbing on live tooled lathes, so there must be certain functions enabled on certain classes of machine.

Gear machining on a CNC lathe through hobbing requires a special live toolholder to mount the hob. Y axis is not mandatory but will allow the use of the whol...

2012年2月19日 · The gear will not have a true involute which produces a rolling action. If the tooth form is incorrect, you may end up with a sliding action or even a binding action.

Gear hobbing allows both machining straight and helical gears as well as splines. Gear hobbing is limited to external machining. This document will guide you through all the basic gear …

With our driven gear hobber you can perform the machining of gears directly on the turret lathe, avoiding the dead times due to the set-up on two different machines (lathe and gear-hobbing). The machining of cylindrical gears with straight or helical teeth, as well as conical gears with straight teeth, is possible.
