Standard handwheels can be modified with custom bore sizes and keyways to fit your specific shafts. Manufacturers like ZheJiang Dream Industry Limited provide precise CNC machining services to customize mounting types, including through bores, keyway bores, D bores, and square bores, ensuring a perfect fit for industrial machinery.
Modifying a standard machine spoked handwheel involves precise CNC turning, milling, and slotting processes. This allows operators to adjust the inner mounting dimensions while preserving the structural integrity of the outer handwheel, which is available in diameters ranging from 45mm to 2000mm. Standard materials such as Stainless Steel (304/316L), Aluminum, Cast Iron, Bakelite, and Brass can all undergo bore and keyway modifications.
To ensure exact alignment with your existing power transmission systems, the machining process relies on 2D and 3D technical files. Accepted formats include PDF, CAD, DWG, DXF, STEP, IGS, and STP. This digital precision prevents misalignment and reduces mechanical wear during long-term industrial operation.
Quality control procedures govern every modification stage. All processes comply with ISO 9001 standards, covering raw material inspection, semi-finished product inspection, and final dimensional checks. Real-world applications of these customized components include industrial valve setups in the United States, where 8,000 valve handwheels were modified and delivered with consistent dimensional accuracy for pipeline control systems.

What technical files are required to modify the bore and keyway?
We accept standard 2D and 3D engineering files, including PDF, CAD, DWG, DXF, STEP, IGS, and STP. These files allow our engineering team to program the CNC machinery for precise slotting and drilling.
Can you machine keyways on plastic or Bakelite handwheels?
Yes. CNC modification services apply to metal handwheels (Stainless Steel, Aluminum, Cast Iron, Brass) as well as engineering plastics, Phenolic, and Bakelite materials.
How do you ensure the modified keyway fits our shaft perfectly?
We perform full dimensional inspections and first article inspections (FAI) under an ISO 9001 certified quality system. Keyway and bore dimensions are verified against your approved technical drawings to control tolerances within ±0.03 mm.
Modifying the bore size and keyway of standard machine spoked handwheels is an efficient, cost-effective solution to ensure compatibility with your existing shafts. Utilizing professional OEM and ODM manufacturing services ensures that modified components maintain their structural strength, anti-slip performance, and corrosion resistance. For international shipping, standard express options like DHL, UPS, and FedEx, as well as air and sea freight, are available to meet project timelines.
