Precision gear rack can be used in many occasions. Many machines like to use gear rack as transmission element, which has a great relationship with its high accuracy. In the process of rack machining, there will be some problems that affect the accuracy of the rack, which is a common phenomenon of tooth surface arris. How to deal with the tooth surface arris in precision gear rack processing?

There are many reasons for the edge of the tooth surface in precision rack machining, and the phenomenon of poor uniformity of the cutter teeth appears after hob grinding. Then, the axial running range of the hob is too large. In addition, too large radial runout can also lead to this situation.

Treatment method: The quality of the hob blade grinding shall be strictly controlled during the rack processing. If the hob is too dull, it shall be replaced in time. Check the installation position accuracy of the hob, and do not knock hard when installing the hob so as not to affect its accuracy. In order to maintain the stability of the hob, the end face of the washer shall be leveled before the rack processing, and the end face of the nut shall be adjusted to ensure that there is no clearance after the bracket is installed. Regularly check the rotation accuracy of the machine tool spindle and adjust the hob spindle bearing.

The above is an introduction to how to deal with the tooth surface arris in precision gear rack processing. If you need precision gear rack processing, please consult the iHF Hefa gear manufacturer.
