Cross Knob

A metal operating component featuring a four-leaf petal-shaped profile, designed to interface with equipment shafts or adjustment screws via a central mounting hole. It enables functions such as opening/closing fluid valves, fine-tuning mechanical positions, or locking mechanisms. The cross structure distributes force across multiple points, offering superior grip and leverage compared to traditional round handwheels. It is ideal for automated production lines and precision instrument panels where space is limited or frequent manual intervention is required.

The part surface undergoes high-grit mirror polishing, delivering a highly reflective metallic finish that enhances aesthetic appeal and facilitates cleaning in hygienic environments like food processing and medical facilities. Key manufacturing challenges include maintaining the smoothness of irregular curved surfaces and uniform edge chamfers. We strictly control the process to prevent deformation or scratches caused by local overheating during polishing, while ensuring coaxiality between the central hole and the outer contour for smooth rotational operation.

Leveraging our multi-axis machining centers and professional polishing workshops, we offer customized production for various base materials, including stainless steel and aluminum alloys. Our one-stop manufacturing service covers everything from 3D drawing review to surface finishing. Adhering to the ISO 9001 quality management system, we strictly control key mating dimensions and surface roughness. We provide material certificates and inspection reports to meet the dual standards of appearance and performance required by industries such as medical devices, semiconductor equipment, and high-end packaging machinery.
