Product Description

This custom CNC machined aluminum winch drum is designed for compact cable winding mechanisms used to lower inspection probes or lightweight sensors from UAV support systems. The helical groove guides the cable across the barrel, while the flanges help prevent it from slipping off the sides during winding.
Aluminum alloy provides a lightweight option for compact rotating components. The barrel diameter, groove pitch and surface finish should be matched to the cable diameter, minimum bend radius and required winding capacity.
Before production, confirm the shaft interface, cable specification, maximum working load, winding direction and available installation space. Critical checks include shaft bore dimensions, groove geometry, flange runout and the intended cable clearance.

    The engineering team reviewed our drawings carefully and asked practical questions before production. This helped clarify the tolerance, surface treatment, and assembly requirements. The finished parts met our expectations, and the communication process was efficient and professional. We would consider working with them again for future CNC projects
