Xiangxing Xin is a supplier of CNC Machined Domed Knurled Knob components for manual adjustment and custom hardware assemblies. The rounded top forms the upper profile, while the separated knurled bands provide textured areas for hand contact.
Customization covers body diameter, overall height, dome contour, groove positions, and knurl geometry. Knurl pitch and depth can be reviewed together with the material and finished outside diameter to establish the required appearance and handling feel.
The mounting interface is defined by the customer's assembly. A threaded bore, plain bore, set-screw hole, or another specified connection can be evaluated after reviewing the mating component. Visible surfaces and functional interfaces can have separate inspection criteria.

The rounded top creates a continuous upper contour. Dome height and curvature can be adjusted to suit the available space and surrounding design.
Three diamond-knurled bands provide textured contact areas around the body. Band width and pattern can be specified according to the desired grip and appearance.
Two smooth recessed bands divide the knurled sections. Their width, depth, and edge transitions can be coordinated with the overall proportions.
The connection can be designed around the mating shaft or fastener. Bore dimensions, thread engagement, and any retention features are confirmed before production.
Confirm the material, overall dimensions, dome contour, mounting interface, and knurl requirements. Where handling feel matters, agree on a reference sample or suitable acceptance criteria.
Turn the cylindrical body, domed top, and circumferential grooves. Plan the machining sequence and allowances around the final knurled diameter.
For the CNC Machined Domed Knurled Knob, evaluate form knurling or cut knurling according to material, geometry, and pattern requirements. Control pattern tracking and the boundaries of each knurled band.
Machine the specified bore, thread, or retention features in a suitable sequence. Deburr the component and apply the agreed finish while preserving the defined knurl profile.
Check dimensions, mounting fit, pattern consistency, and surface condition. Use suitable protective packaging to reduce contact marks on the dome and knurled bands.
Yes. Please specify the pattern, pitch, band widths, groove positions, and finished outside diameter. A reference sample can help confirm the desired appearance and handling feel.
Yes. We can evaluate a threaded bore, plain bore, set-screw hole, or another specified interface. Please provide the mating dimensions, engagement depth, and retention requirements.
We review the knurl geometry and edge conditions together with the intended use. Deburring and finishing methods are selected to remove unwanted burrs while retaining the agreed texture. A sample can be used for handling approval.
Xiangxing Xin supports starting with one sample for custom CNC components. Pricing and production arrangements depend on the material, dimensions, knurl pattern, mounting features, and finish.
After engineering review, material and labor costs may be charged initially and refunded in full when a subsequent production order is placed. The arrangement and applicable conditions will be confirmed in the quotation.
Please provide a PDF or DWG/DXF drawing and, where available, a STEP or IGES model. Include material, quantity, mounting details, critical tolerances, knurl requirements, and surface finish. Photos or samples can also be reviewed to establish an agreed specification.
Xiamen Xiangxing Xin Industry and Trade Co., Ltd. reviews the external profile, knurl geometry, and mounting interface together to clarify manufacturing requirements before production.
CNC turning supports the body, dome, and grooves. Additional machining can be evaluated for mounting holes, threads, and retention features.
Samples can be used to confirm knurl definition, edge feel, dome appearance, and mounting fit before batch production.
Our company holds ISO 9001 and IATF 16949 quality management system certifications. Material certificates and dimensional inspection reports can be arranged according to the order. Confirmed drawings and approved samples provide a reference for repeat production.
