Hob cutters for manufacturing gears and worm gears need to meet the highest standards when it comes to precision and service life. Haas Multigrind customers require gear qualities q1–q3. This is true whether it’s a very small tool, or a 600-kilogram gear-cutting tool used to manufacture gear wheels for the winches on freighters and container ships.
The dimensional accuracy and surface quality of a gear component are absolutely key to an efficient transmission of power and smooth operation. On the Multigrind® CB and CA grinding centers, grinding gears from solid is just as easy as processing premilled blanks that are subsequently hardened. Haas grinding software enables users to quickly and easily define the respective workpiece, including clearance angle calculations and collision avoidance simulation. Thanks to our machines’ kinematics, large grinding wheels can be used when rough grinding. For the operator, this means a longer service life and more material removed.
Using a compensation program that mathematically compensates for the hysteresis of the probe, the components can be probed in the machine. The deep grooves and fine contours of the teeth can also be processed in one clamping, regardless of the size of the workpiece. The intelligent integrated 3-D probing system guarantees maximum precision during the entire grinding process. This is how to achieve repeatability and accuracy of a few microns, and avoid time-consuming clamping and unclamping.
The grinding wheels can be trued in the machine using the integrated dresser unit. This is another way our machines save time and offer added precision.
