Helical Teeth Racks

Select appropriate materials based on the application requirements and performance characteristics of the rack. These materials possess excellent mechanical properties and wear resistance.

Use equipment like sawing machines or wire-cut electrical discharge machines to cut the raw materials into blanks with dimensions close to the final product, laying the foundation for subsequent processing.

As a key step, numerical control (NC) milling machines or specialized gear processing machines are used for tooth profile machining. During processing, the movement of the machine tool must be precisely controlled according to design parameters (e.g., module, number of teeth, helix angle) to machine the helical tooth profile that meets requirements. In the milling process, it is essential to select suitable milling cutters and cutting parameters (such as cutting speed and feed rate) to ensure the accuracy and surface quality of the tooth profile.

Depending on the material and application requirements, some racks may undergo heat treatment processes like quenching and tempering. These processes help improve the rack's hardness, strength, and wear resistance, thereby extending its service life.

Perform finish machining operations (such as surface grinding) on the racks that have undergone heat treatment or direct processing. This further enhances the smoothness and accuracy of the tooth surface, ensuring that the rack's dimensional tolerance and surface roughness meet standard requirements.

Use professional inspection equipment (e.g., coordinate measuring machines) to inspect the finished racks in terms of dimensional accuracy, tooth profile accuracy, and surface quality, ensuring they comply with the DIN standard and design requirements. After passing the inspection, the racks are assembled and prepared for use.
